UAS: UAS Regulation (Delegated Regulation (EU) 2019/945), explained

The UAS Regulation sets the design, class-label (C0 to C6), conformity assessment, CE marking and operator duties for drones placed on the EU market for the open and declared specific categories. It entered into force on 1 July 2019, and since 1 January 2024 a drone flown in the open category generally needs a class identification label.

Who it applies to

Covered by the act

  • The design and manufacture of unmanned aircraft systems intended to be operated under the rules and conditions of Implementing Regulation (EU) 2019/947, and of remote identification add-ons, plus the rules on making UAS, accessories kits and remote identification add-ons available on the market and on their free movement in the Union
  • Chapter II products: UAS intended to be operated under the rules of the open category or under an operational declaration in the specific category, other than privately built UAS, bearing one of the seven class identification labels of Parts 1 to 5, 16 and 17 of the Annex, that is C0, C1, C2, C3, C4, C5 and C6; class C5 accessories kits as set out in Part 16; and direct remote identification add-ons as set out in Part 6
  • Chapter III: UAS operated in the certified category and in the specific category other than under a declaration, whose design, production and maintenance must be certified where the UAS has a characteristic dimension of 3 metres or more and is designed to be operated over assemblies of people unless lighter than air, is designed to transport people, is designed to carry dangerous goods and requires a high level of robustness, or where the competent authority has concluded that the operational risk cannot be mitigated without certification
  • Chapter IV: UAS operators that have their principal place of business, are established or reside in a third country, if their UAS are operated in the Union (Art. 2(3)); those operators must comply with Implementing Regulation (EU) 2019/947 for UAS operations within the single European sky airspace, meaning the airspace above the territory to which the Treaties apply and any other airspace where Member States apply Regulation (EC) No 551/2004 (Art. 1, Art. 3, point (34), and Art. 41(1))
  • The economic operators in the chain, defined as the manufacturer, the authorised representative of the manufacturer, the importer and the distributor of the UAS, with an importer or distributor treated as the manufacturer where it places a product on the market under its own name or trademark or modifies a product already on the market in a way that may affect compliance

Derived and downstream products

  • The regulation does not apply to UAS intended to be exclusively operated indoors, and the basic regulation it is adopted under does not apply to aircraft and their remote control equipment while carrying out military, customs, police, search and rescue, firefighting, border control, coastguard or similar activities or services under the control and responsibility of a Member State (Art. 2(4) of the UAS Regulation; Art. 2(3)(a) of Regulation (EU) 2018/1139)
  • The seven class identification labels map onto the operating rules: C0 and C1 are flown in open subcategory A1, C2 in subcategory A2, and C2, C3 and C4 in subcategory A3, while C5 is the aircraft for standard scenario STS-01, visual line of sight over a controlled ground area in a populated environment, and C6 for STS-02, beyond visual line of sight with airspace observers, both in the specific category under an operational declaration (Art. 4(1)(a) of Implementing Regulation (EU) 2019/947 and points UAS.OPEN.020, UAS.OPEN.030, UAS.OPEN.040, UAS.STS-01.020 and UAS.STS-02.020 of its Annex)
  • The class limits are cumulative design targets, not just mass bands: C0 is below 250 g with a maximum level-flight speed of 19 m/s and a 120 m height limit; C1 is below 900 g or transmits less than 80 J to a human head on impact at terminal velocity, with the same speed and height limits, a serial number, direct remote identification, geo-awareness, lights and a sound power level within the Part 15 limits; C2 is below 4 kg with a low-speed mode of no more than 3 m/s, a protected command and control link and the same identification and awareness functions; C3 is below 25 kg and less than 3 m in characteristic dimension; C4 is below 25 kg with no automatic control modes beyond flight stabilisation and lost-link assistance; C5 follows the C3 requirements with a flight termination function, a 5 m/s low-speed mode and link monitoring; and C6 follows the C3 requirements with a maximum ground speed of 50 m/s, programmable operational volume limits and flight termination (Annex, Parts 1 to 5, 16 and 17)
  • Internal production control under Part 7 is only available for products assessed against Parts 1, 5, 6, 16 or 17, that is classes C0, C4, C5 and C6 and remote identification add-ons, and only where the manufacturer has applied harmonised standards for all requirements for which such standards exist; classes C1, C2 and C3 always go through EU-type examination with conformity to type under Part 8 or full quality assurance under Part 9, and Part 9 may not be used for a UAS that is a toy (Art. 13(2))
  • The notified body identification number is added after the CE marking only where the full quality assurance procedure of Part 9 is applied; a product assessed under Part 8 carries the CE marking and the class label without a notified body number even though a notified body issued the EU-type examination certificate (Art. 16(5) and Art. 39(1)(c))
  • A UAS that is a toy within the meaning of Directive 2009/48/EC must comply with that directive as well, and points (4), (5) and (6) of Part 1 on controllability, injury minimisation and electric power do not apply to class C0 toys; a UAS that is not a toy must meet the relevant health and safety requirements of Directive 2006/42/EC only for risks other than those linked to the safety of the flight, a reference read against Regulation (EU) 2023/1230 from 20 January 2027 (Art. 4(2), Annex Part 1 point (10), recitals 5 and 6 of the base act; Regulation (EU) 2023/1230, Art. 51(2) and Art. 54 as corrected by corrigendum 32023R1230R(01)); the toy directive is itself repealed by Regulation (EU) 2025/2509 on the safety of toys with effect from 1 August 2030, from when the three references to Directive 2009/48/EC in this Regulation are read as references to that regulation (Regulation (EU) 2025/2509, Art. 56 and Art. 59)
  • Directive 2014/53/EU on radio equipment applies to unmanned aircraft that are not subject to certification and are not intended to be operated only on frequencies allocated for protected aeronautical use, where they intentionally emit or receive electromagnetic waves below 3 000 GHz, and Directive 2014/30/EU on electromagnetic compatibility applies where they fall outside the radio directive, so most consumer drones carry a single CE marking covering several acts (recitals 7 to 9 of the base act and Art. 14(4))
  • Software updates of a product already made available on the market may only be made if they do not affect the product's compliance, which makes over-the-air firmware a conformity matter and not only a feature matter (Art. 4(3))
  • A product in conformity with harmonised standards whose references are published in the Official Journal is presumed to conform to the requirements those standards cover; the only harmonised standard listed so far is EN 4709-002:2023, Aerospace series - Unmanned Aircraft Systems - Part 002: Direct Remote identification, published by Commission Implementing Decision (EU) 2024/2103 of 30 July 2024 and published with a restriction: it does not confer a presumption of conformity with the broadcast requirements in point (12)(b) of Part 2, point (14)(b) of Part 3, point (9)(b) of Part 4 and point (3) of Part 6 of the Annex (Art. 12; Commission Implementing Decision (EU) 2024/2103, Art. 1 and Annex)
  • Classes C5 and C6 sit at the boundary with the specific category: a class C5 UAS may be a class C3 UAS fitted with an accessories kit that converts it, the class C5 label must then be affixed to every accessory, the kit may be placed on the market on its own, and it must not change the software of the class C3 UAS (Annex, Part 16, point (8))
  • Seven corrigenda have been published to the original act, on 19 June 2019, 25 June 2019, 4 October 2019, 6 January 2022, 24 November 2022, 27 June 2024 and 12 January 2026, but none of them concerns the English language version: they correct the Czech and Spanish, French, Danish and Polish, Portuguese, Romanian, Hungarian and Maltese versions respectively, which is why the English consolidated text carries no corrigendum markers (CELEX 32019R0945R(01) to 32019R0945R(07))

Does UAS apply to your product?

Three questions, a first answer from the regulation’s own scope rules. No account needed.

The rules behind this check
  1. UAS intended to be exclusively operated indoors, Unmanned aircraft and their remote control equipment carrying out military, customs, police, search and rescue, firefighting, border control, coastguard or similar activities under the responsibility of a Member State · any · any Not in scope The regulation does not apply to UAS intended to be exclusively operated indoors, and the basic regulation it rests on does not apply to aircraft and their remote control equipment while carrying out military, customs, police, search and rescue, firefighting, border control, coastguard or similar activities or services under the control and responsibility of a Member State, undertaken in the public interest by or on behalf of a body vested with the powers of a public authority. National rules and, in Denmark, the separate provisions of the drone order on public authorities apply instead; the Member State must still ensure such activities have due regard to the safety objectives of the basic regulation. Source · Art. 2(4)Source · Art. 2(3)(a)
  2. Privately built UAS assembled or manufactured for the builder's own use, not assembled from a ready-to-assemble kit placed on the market by a manufacturer · any · any It depends A UAS assembled or manufactured for the builder's own use is excluded from Chapter II, so it carries no class identification label, no CE marking under this regulation and no EU declaration of conformity; a set of parts placed on the market by a manufacturer as a single ready-to-assemble kit is not privately built and is in scope. A privately built UAS may still be flown in the open category under Article 4(1)(a) of Implementing Regulation (EU) 2019/947, in subcategory A1 below 250 g and in subcategory A3 below 25 kg, and where it is used in the specific category below 120 metres it needs a direct remote identification add-on meeting Part 6 of the Annex, whose serial number is broadcast.

Drone without a class identification label placed on the market before 1 January 2024 · any · any It depends A drone without a class identification label that was placed on the market before 1 January 2024 may continue to be operated in the open category only in subcategory A1 if its maximum take-off mass including payload is below 250 g, or in subcategory A3 if it is below 25 kg including fuel and payload; the wider transitional rules of Article 22, which allowed operation of non-compliant UAS up to 500 g, 2 kg and 25 kg under competency conditions, ended on 31 December 2023. New units of such a model may not be placed on the market for the open category, because Article 4(1)(a) of Implementing Regulation (EU) 2019/947 requires the UAS to belong to one of the seven classes, be privately built or meet the Article 20 conditions. Source · Art. 4(1)(a), Art. 20 and Art. 22
  4. Drone that is a toy within the meaning of Directive 2009/48/EC, marketed for children under 14 with a toy declaration · Manufacturer (including brand owners and modifiers), Importer, Distributor (wholesaler, retailer or online seller of drones), Authorised representative · any It depends A drone that is a toy within the meaning of Directive 2009/48/EC is in scope of this regulation and must comply with the toy directive as well; points (4), (5) and (6) of Part 1, on safe controllability, injury minimisation and exclusively electric power, do not apply to a class C0 UAS that is a toy, the machinery health and safety requirements of Article 4(2) do not apply to toys at all, and the full quality assurance procedure of Part 9 may not be used to assess a toy. In Denmark a toy drone with the class C0 label, or one below 250 g and 19 m/s placed on the market before 1 January 2024, is exempt from the aviation liability insurance minimum.

What you must do

Obligations by role

Manufacturer (including brand owners and modifiers)18
  • Decide which class the UAS is designed for and meet every requirement of that Part: for class C0 a maximum take-off mass below 250 g including payload, a maximum level-flight speed of 19 m/s, a height limited to 120 m above the take-off point, safe controllability, minimised injury and sharp edges, exclusively electric power and a follow-me range of no more than 50 m; for class C1 below 900 g or less than 80 J transmitted to a human head at terminal velocity, plus mechanical strength, a lost-link recovery or flight termination method, lights including at least one green flashing light for night conspicuity and a low-battery warning; for class C2 below 4 kg with a selectable low-speed mode of no more than 3 m/s and a command and control link protected against unauthorised access; for class C3 below 25 kg and less than 3 m in characteristic dimension; for class C4 below 25 kg with no automatic control modes beyond flight stabilisation and lost-link assistance; for class C5 the class C3 requirements without the height limitation and geo-awareness duty, plus flight termination, a 5 m/s low-speed mode and link quality monitoring; and for class C6 the class C3 requirements plus a 50 m/s ground speed limit, programmable operational volume limits, trajectory programming and flight termination. Art. 4(1) and Annex, Parts 1 to 5, 16 and 17
  • Build in the identification and awareness functions the class requires: a direct remote identification system that accepts and integrity-checks the UAS operator registration number and broadcasts in real time, over an open and documented protocol receivable by ordinary mobile devices, the registration number and verification code, the unique serial number, the time stamp, the geographical position and height, the course measured clockwise from true north, the ground speed, the remote pilot position or take-off point and the emergency status, while resisting tampering; and, for classes C1, C2 and C3, a geo-awareness function with an interface to load and update the UAS geographical zone data, a warning when a breach of airspace limitations is detected and a warning when positioning or navigation cannot support the function. Annex, Part 2, points (12) and (13), Part 3, points (14) and (15), and Part 4, points (9) and (10)
  • Determine the A-weighted sound power level of classes C1, C2, C3, C5 and C6 by the Part 13 noise test code (EN ISO 3744:2010), and keep non fixed-wing class C1 and C2 aircraft within the Part 15 limits (81 dB for C1; 81 + 18,5 lg(m/900) dB for C2). Annex, Part 2, points (8) and (9), Part 3, points (10) and (11), Part 4, point (6), Part 13 and Part 15
  • Affix the guaranteed sound power indication of Part 14, the number in dB with the LWA sign and the pictogram, on the aircraft and its packaging. Annex, Part 14
  • Draw up the Part 10 technical documentation before placing the product on the market and keep it updated: a complete product description with photographs or illustrations of external features, markings and internal layout, the versions of all software and firmware involved in compliance, the manufacturer's and installation instructions, conceptual design and manufacturing drawings and schemes with the explanations needed to understand them, the list of harmonised standards applied in full or in part and the solutions adopted where they were not, a copy of the EU declaration of conformity, the EU-type examination certificate where Part 8 was used, design calculations, examination results and test reports, copies of what was submitted to the notified body, supporting evidence for the design solution and the addresses of the places of manufacture and storage; draw it up in an official language of the notified body's Member State or a language that body accepts. Art. 17 and Annex, Part 10

UAS in plain terms

The UAS Regulation, formally Commission Delegated Regulation (EU) 2019/945 on unmanned aircraft systems and on third-country operators of unmanned aircraft systems, is the EU’s product law for drones. It lays down the requirements for the design and manufacture of unmanned aircraft systems intended to be operated under Implementing Regulation (EU) 2019/947 and of remote identification add-ons, the rules for making those products available on the market and moving them freely in the Union, the types of UAS whose design, production and maintenance must be certified, and the rules for UAS operators based in third countries that fly in the single European sky airspace (Art. 1). A UAS is an unmanned aircraft together with its control and monitoring unit, and an unmanned aircraft is any aircraft operating or designed to operate autonomously or to be piloted remotely without a pilot on board (Art. 3, points (1) and (3)).

The centre of the regulation is the class identification label. Chapter II applies to UAS intended for the open category, or for operational declarations in the specific category, that are not privately built and bear one of the seven class identification labels set out in Parts 1 to 5, 16 and 17 of the Annex, that is C0, C1, C2, C3, C4, C5 and C6; it also applies to class C5 accessories kits under Part 16 and to direct remote identification add-ons under Part 6 (Art. 2(1)). The label is not marketing: it states which set of technical requirements the drone meets, and under the operating regulation it decides where and how close to people the drone may be flown. The regulation entered into force on 1 July 2019; classes C5 and C6 arrived with Delegated Regulation (EU) 2020/1058 on 9 August 2020, and the 2024 amendment rebuilt the certification conditions and added a low-battery warning to classes C1, C2 and C3 from 1 May 2025.

Official text Read the regulation on EUR-Lex: consolidated text of 24 June 2025 (CELEX 02019R0945-20250624), which incorporates Delegated Regulations (EU) 2020/1058, (EU) 2022/851, (EU) 2024/1108 and (EU) 2025/1130; the original act (CELEX 32019R0945) and the document information page list the amendments and the seven corrigenda; none of those seven touches the English version, which is why the English consolidated text carries no corrigendum markers. The operating rules are in Implementing Regulation (EU) 2019/947, consolidated text of 1 May 2025.

Scope

Chapter II, the product chapter, covers class-labelled UAS for the open category and for declared operations in the specific category, class C5 accessories kits and direct remote identification add-ons. Chapter III covers UAS operated in the certified category and in the specific category other than under a declaration: since 1 May 2025 their design, production and maintenance must be certified where the UAS has a characteristic dimension of 3 metres or more and is designed to be operated over assemblies of people unless it is lighter than air, is designed to transport people, is designed to carry dangerous goods and needs a high level of robustness to protect third parties in an accident, or where the competent authority has concluded on the operator’s risk assessment that the risk cannot be mitigated without certification (Art. 40(1)). Chapter IV covers UAS operators established, resident or with their principal place of business in a third country (Art. 2(3) and Art. 41).

Three things fall outside. UAS intended to be exclusively operated indoors are not covered at all (Art. 2(4)). Privately built UAS, meaning aircraft assembled or manufactured for the builder’s own use but not aircraft assembled from a ready-to-assemble kit placed on the market by a manufacturer, are excluded from the class regime (Art. 2(1)(a) and Art. 3, point (22)). And the basic regulation the UAS Regulation rests on does not apply to aircraft and their remote control equipment while carrying out military, customs, police, search and rescue, firefighting, border control, coastguard or similar activities under the control and responsibility of a Member State (Regulation (EU) 2018/1139, Art. 2(3)(a)).

Other product law applies alongside. A drone that is a toy within the meaning of Directive 2009/48/EC must meet the toy directive as well, while points (4), (5) and (6) of Part 1 do not apply to class C0 toys; a drone that is not a toy must meet the relevant health and safety requirements of Directive 2006/42/EC only for risks other than flight safety, a reference read against Regulation (EU) 2023/1230 on machinery once the directive is repealed on 20 January 2027 (Art. 4(2); Regulation (EU) 2023/1230, Art. 51(2) and Art. 54, as corrected by corrigendum 32023R1230R(01), OJ L 169, 4.7.2023, p. 35). Directive 2014/53/EU on radio equipment applies to drones that are not subject to certification and are not confined to protected aeronautical frequencies, and Directive 2014/30/EU on electromagnetic compatibility applies where the radio directive does not (recitals 7 to 9). Where several acts require a declaration, one EU declaration of conformity covers them all (Art. 14(4)).

What you must do

The seven classes C0 to C6

Class C0 is an aircraft below 250 g including payload, with a maximum speed in level flight of 19 m/s, a height above the take-off point limited to 120 m, safe controllability, a design that minimises injury and avoids sharp edges, exclusively electric power and a follow-me range of no more than 50 m (Part 1). Class C1 is below 900 g, or transmits less than 80 J to a human head on impact at terminal velocity, and adds mechanical strength, a reliable lost-link recovery or flight-termination method, a sound power level within the Part 15 limits, an ANSI/CTA-2063-A-2019 serial number, direct remote identification, geo-awareness, a low-battery warning, controllability lights and at least one green flashing light for night conspicuity (Part 2). Class C2 is below 4 kg and adds a selectable low-speed mode of no more than 3 m/s for non fixed-wing aircraft and a command and control link protected against unauthorised access (Part 3). Class C3 is below 25 kg with a maximum characteristic dimension of less than 3 m (Part 4). Class C4 is below 25 kg and, unusually, must not be capable of automatic control modes beyond flight stabilisation assistance and lost-link assistance (Part 5).

Classes C5 and C6 were added for the specific category under declaration. A class C5 UAS meets the class C3 requirements except the height limitation and the geo-awareness duty, and must be a non fixed-wing aircraft unless tethered, show the remote pilot its height above the surface, offer a selectable low-speed mode of no more than 5 m/s, provide a reliable and independent means to terminate the flight that forces a descent, prevents powered horizontal movement and reduces impact dynamics, and let the remote pilot monitor the link quality with alerts before and on loss (Part 16). A class C6 UAS meets the class C3 requirements except the height limitation, the electric-power rule and the geo-awareness duty, and adds a maximum ground speed of 50 m/s, position, speed and height information in flight, means to prevent breaching a programmable operational volume, independent flight termination and trajectory programming (Part 17).

Conformity assessment and notified bodies

Article 13 offers three routes: internal production control under Part 7, EU-type examination followed by conformity to type based on internal production control under Part 8, and conformity based on full quality assurance under Part 9. Part 7 is only available when assessing a product against Parts 1, 5, 6, 16 or 17, that is classes C0, C4, C5 and C6 and remote identification add-ons, and only where the manufacturer has applied harmonised standards for every requirement for which such standards exist. Classes C1, C2 and C3 therefore always involve a notified body. Part 9 is closed to products that are toys. The assessment must take account of all intended and foreseeable operating conditions, and a product in conformity with harmonised standards published in the Official Journal is presumed to conform to the requirements they cover (Art. 12); the only harmonised standard listed so far is EN 4709-002:2023 on direct remote identification, published by Commission Implementing Decision (EU) 2024/2103 of 30 July 2024 with a restriction: it does not cover the broadcast requirements of point (12)(b) of Part 2, point (14)(b) of Part 3, point (9)(b) of Part 4 and point (3) of Part 6, so a manufacturer cannot rely on it for those points.

Declaration, CE marking, class label and sound power level

The manufacturer draws up the Part 10 technical documentation before placing the product on the market, keeps it and the EU declaration of conformity for 10 years, and draws the declaration up to the Part 11 model stating that compliance with Parts 1 to 6, 16 and 17 has been demonstrated, identifying the class and, for non fixed-wing aircraft, the guaranteed sound power level. Each product ships with a copy of the declaration or with the Part 12 simplified declaration carrying the exact internet address of the full text (Art. 6(8) and Art. 14). Before placing the product on the market the manufacturer affixes the CE marking visibly, legibly and indelibly, followed by the notified body’s identification number only where Part 9 was used; the class identification label at least 5 mm high on the aircraft, on each accessory of a class C5 kit and on the packaging, with no misleading markings; the sound power indication of Part 14 where applicable; the type and unique serial number; and the manufacturer’s name, trade name or trademark, website address and a single postal contact address (Art. 15 and Art. 16). Importers add their own identification (Art. 8(3)).

Noise is measured by the Part 13 test code, based on EN ISO 3744:2010, with the rotors at hovering speed under maximum take-off mass over a reflecting plane and a hemispherical microphone array, repeated until two values differ by no more than 1 dB. Part 15 sets maximum sound power levels only for non fixed-wing classes C1 and C2, in three columns: from entry into force, from two years after and from four years after. For class C1, with a maximum take-off mass of 250 g or more and below 900 g, the limits are 85 dB, 83 dB and 81 dB. For class C2, with a maximum take-off mass m of 900 g or more and below 4 000 g, they are 85 + 18,5 lg(m/900) dB, 83 + 18,5 lg(m/900) dB and 81 + 18,5 lg(m/900) dB, where lg is the base 10 logarithm. Because the regulation entered into force on 1 July 2019, the two-year column applied from 1 July 2021 and the strictest column has applied since 1 July 2023, which puts the class C2 ceiling at 81 dB at 900 g and at roughly 93 dB at 4 000 g.

Remote identification, geo-awareness and the information notice

Classes C1, C2 and C3 must carry direct remote identification that accepts the UAS operator registration number, verifies the integrity of the full string and raises an error if the check fails, and then broadcasts in real time, over an open and documented protocol receivable by ordinary mobile devices, the registration number and verification code, the aircraft’s unique serial number, a time stamp, the geographical position and height above the surface or take-off point, the course measured clockwise from true north, the ground speed, the remote pilot’s position or the take-off point, and the emergency status, while resisting tampering. The same classes must carry geo-awareness: an interface to load and update UAS geographical zone data without degrading it, a warning when a potential breach of airspace limitations is detected, and a warning when positioning or navigation cannot support the function. A separate direct remote identification add-on under Part 6 broadcasts the add-on’s own serial number and is the route for privately built aircraft in the specific category (Art. 40(5)). Every class ships with manufacturer’s instructions and the information notice published by EASA on the applicable limitations and obligations, in the language the Member State determines.

Obligations by role

  • Manufacturers design to the class, run the conformity assessment, hold the technical documentation, draw up the declaration, apply the CE marking, class label, sound power indication, type and serial number and their contact details, supply instructions and the EASA notice, keep series production in conformity, watch software updates, act on non-conformity, keep 10-year traceability and notify the market surveillance authority when placing a class C5 or C6 UAS or a class C5 add-on on the market (Art. 6).
  • Authorised representatives act on a written mandate that cannot include designing to the Annex or drawing up the technical documentation, keep the declaration and documentation available for 10 years, answer reasoned requests and cooperate on corrective action (Art. 7).
  • Importers verify the assessment, documentation, markings and accompanying documents before placing a product on the market, add their own identification, protect compliance in storage and transport, sample-test where the risks warrant it, act on non-conformity, keep the declaration for 10 years and notify for classes C5 and C6 (Art. 8).
  • Distributors act with due care, verify the CE marking, class label, sound power indication, documents and identification, ensure the instructions and notice are in the right language, hold back products they believe to be non-compliant, protect compliance in storage and transport and cooperate with authorities (Art. 9).
  • UAS operators register, upload the registration number, keep the geo-awareness data current and fly within the subcategory or authorisation their aircraft’s class allows; third-country operators follow Implementing Regulation (EU) 2019/947 in the single European sky airspace (Art. 41).

An importer or distributor that sells under its own name or trademark, or modifies a product already on the market in a way that may affect compliance, becomes the manufacturer for the whole of Chapter II (Art. 10).

The operating rules in Regulation (EU) 2019/947

The product rules only pay off if the customer can fly. Implementing Regulation (EU) 2019/947 has applied since 31 December 2020 and divides operations into the open, specific and certified categories. The open category requires the UAS to belong to one of the seven classes, be privately built or meet the Article 20 legacy conditions, to be below 25 kg, kept in visual line of sight, within 120 metres of the closest point of the surface, at a safe distance from people, never over assemblies of people, and to carry no dangerous goods and drop no material (Art. 4). Class C0 and C1 aircraft fly in subcategory A1, class C2 in A2 at a minimum horizontal distance from uninvolved people, and classes C2, C3 and C4 in A3 well away from residential, commercial and recreational areas. Operations outside those limits need an operational authorisation from the competent authority of the Member State of registration, or an operational declaration where the operation matches standard scenario STS-01, visual line of sight over a controlled ground area in a populated environment with a class C5 aircraft, or STS-02, beyond visual line of sight with airspace observers and a class C6 aircraft (Art. 5). Declarations based on national standard scenarios stopped being valid on 1 January 2026 (Art. 23(4)).

The transition is now closed. Article 22 allowed unlabelled aircraft in the open category until 31 December 2023 under mass-based conditions, and Article 20 still lets drones placed on the market before 1 January 2024 be flown in subcategory A1 below 250 g or A3 below 25 kg. From 1 January 2024 a drone newly placed on the market without a class label cannot lawfully be used in the open category unless it is privately built, which is why the class mark became a selling point that autumn.

Enforcement and penalties

Member States organise market surveillance of products placed on the Union market and control of products entering it, and must make their market surveillance and border control authorities cooperate with the aviation competent authorities designated under Article 17 of Implementing Regulation (EU) 2019/947, using the occurrence reporting system of Regulation (EU) No 376/2014 (Art. 35). The articles of Regulation (EC) No 765/2008 cited there were deleted on 16 July 2021 by Article 39 of Regulation (EU) 2019/1020 and are read as that regulation, whose Annex I lists Regulation (EU) 2018/1139 as point 70 as regards unmanned aircraft; Article 5(3) of the UAS Regulation separately makes Article 4(1) to (4) of Regulation (EU) 2019/1020 apply from the same date, so every UAS placed on the market needs a responsible economic operator established in the Union. Article 30 of Regulation (EC) No 765/2008 on the general principles of the CE marking, cited in Article 15, survives.

Where an authority has sufficient reason to believe a product presents a risk it evaluates it against all of Chapter II, requires corrective action, withdrawal or recall within a period commensurate with the risk, informs the notified body, and takes provisional measures if the operator does not act, notifying the Commission and the other Member States; an unopposed measure is deemed justified after three months, and the Union safeguard procedure resolves disagreements (Art. 36 to Art. 38). Article 39 lists eleven forms of formal non-compliance that must be ended, from a CE marking affixed in violation of the rules or not at all, through a missing class identification label, sound power indication, serial number, manual or information notice, to a missing or incorrect EU declaration of conformity, incomplete technical documentation and missing manufacturer or importer identification.

The regulation itself sets no penalties, because it is a Commission delegated act; the duty to penalise sits one level up, in Article 131 of Regulation (EU) 2018/1139, which requires Member States to lay down effective, proportionate and dissuasive penalties for infringements of that regulation and of the delegated acts adopted under it. The sanctions themselves come from national law. In Denmark, executive order nr. 1735 of 24 November 2020 on market surveillance of the drone area makes Trafikstyrelsen the supervisory authority for the product requirements and lets it demand access without a court order to business books, documents, information, business premises, storage and means of transport, take any product free of charge for testing, obtain expert opinions, order warnings to users, an end to misleading marketing, remedial action, a stop to sales, withdrawal, recall or destruction, order an online interface to change or remove content referring to a non-compliant drone, act in the operator’s place where it cannot be located, and publish its measures; refusing access, withholding documents or products, ignoring an order or failing to report on the measures taken is punishable by fine, with corporate liability under chapter 5 of the criminal code (executive order nr. 1735/2020, § 3 to § 12). On the operating side, executive order nr. 1649 of 12 December 2023, in force since 1 January 2024 and amended by executive order nr. 527 of 20 May 2025, makes Trafikstyrelsen the competent authority under Implementing Regulation (EU) 2019/947 and punishes breaches of its insurance, competency, distance and zone rules with a fine (executive order nr. 1649/2023, § 33). Drones are not one of the product areas of the Danish product act, so the department Markedsovervågning of Erhvervsstyrelsen that continues Sikkerhedsstyrelsen’s work from January 2026 has no role in drone product surveillance.

How Conphora helps

Conphora monitors the UAS Regulation, its amendments, the operating rules in Implementing Regulation (EU) 2019/947 and the Danish executive orders, and maps your drones against the class requirements, the conformity assessment routes, the marking and instruction duties and the transitional dates, flagging gaps in the class identification label, the CE marking, the sound power indication, the serial number, the EU declaration of conformity and the technical documentation before they become enforcement problems. The platform helps you keep one declaration covering the UAS, radio, electromagnetic compatibility, toy and machinery rules the same product needs, keep the 10-year records and the supplier and customer traceability, and alerts you when a class requirement, a harmonised standard, a Danish executive order or the operating framework changes.

Penalties

Enforced by Member States organise market surveillance of UAS placed on the Union market and control of UAS entering it, and their market surveillance and border control authorities must cooperate with the competent authorities designated under Article 17 of Implementing Regulation (EU) 2019/947; Article 35(1) still cites Article 15(3) and Articles 16 to 26 of Regulation (EC) No 765/2008 for surveillance of products placed on the market, Article 35(2) cites Article 15(5) and Articles 27, 28 and 29 for control of products entering it, Article 35(3) cites the information systems of Articles 22 and 23, and Article 36(1) cites Article 21; all of those are read as Regulation (EU) 2019/1020 since 16 July 2021, when Chapter III of Regulation (EC) No 765/2008, containing Articles 15 to 29, was deleted by Article 39(1), point (4), of that regulation, while Article 30 on the general principles of the CE marking, cited in Article 15 and Article 39(1)(a), sits in Chapter IV and survives. Regulation (EU) 2019/1020 lists Regulation (EU) 2018/1139 as point 70 of its Annex I in so far as the design, production and placing on the market of aircraft referred to in points (a) and (b) of Article 2(1) of that regulation, where it concerns unmanned aircraft and their engines, propellers, parts and equipment to control them remotely, are concerned, so it is the basic regulation and not this delegated act that is listed, and Regulation (EU) 2019/945 is not in the Article 4(5) list either, and Article 5(3) of the UAS Regulation itself makes Article 4(1) to (4) of Regulation (EU) 2019/1020 apply from 16 July 2021, so every UAS placed on the market needs an economic operator established in the Union. In Denmark, Trafikstyrelsen is the supervisory authority for the product requirements under executive order nr. 1735 of 24 November 2020 on market surveillance of the drone area (bekendtgørelse om markedsovervågning af droneområdet), issued under the aviation act, and the same authority is the competent authority for drone operations under executive order nr. 1649 of 12 December 2023 supplementing Implementing Regulation (EU) 2019/947; the product side has never moved to Sikkerhedsstyrelsen or its successor department Markedsovervågning of Erhvervsstyrelsen, because the product act (lov om produkter og markedsovervågning) does not list drones among its product areas. The toolkit is corrective action, a prohibition or restriction of the making available, withdrawal or recall, orders to end formal non-compliance such as a missing CE marking, class identification label, sound power indication, serial number, manual, information notice, EU declaration of conformity, technical documentation or operator identification, and in Denmark orders to warn users, stop misleading marketing, remedy, stop sales, withdraw, recall or destroy a drone, orders to an online interface to change or remove content referring to a non-compliant drone, and fines with corporate liability under chapter 5 of the criminal code.

Delegated Regulation (EU) 2019/945 contains no penalty article of its own, because it is a Commission delegated act adopted under Articles 58 and 61 of Regulation (EU) 2018/1139; the duty to penalise sits in the basic regulation instead. Article 131 of Regulation (EU) 2018/1139 requires Member States to lay down the rules on penalties applicable to infringement of that regulation and of the delegated and implementing acts adopted on the basis thereof, and to make those penalties effective, proportionate and dissuasive. Article 41 of Regulation (EU) 2019/1020 does not add to that, because it only covers the Union harmonisation legislation listed in Annex II to that regulation, and neither Regulation (EU) 2018/1139 nor this Regulation is on that list. Everything else runs through the market surveillance chapter and national law. Market surveillance authorities that have sufficient reason to believe a product presents a risk to health or safety or to other public interests evaluate it against all the requirements of Chapter II, require the economic operator without delay to take corrective action, withdraw or recall the product within a period commensurate with the risk, inform the notified body, and where the operator does not act take provisional measures to prohibit or restrict the making available, withdraw or recall it, notifying the Commission and the other Member States; a measure not objected to within three months is deemed justified and the Union safeguard procedure settles disputes, and a compliant product that still presents a risk can be treated the same way. Formal non-compliance must be ended in eleven listed cases: a CE marking affixed in violation of Article 30 of Regulation (EC) No 765/2008 or of Article 15 or 16, a missing CE marking or type, a missing or wrongly affixed notified body number where Part 9 was applied, a missing class identification label, a missing sound power indication where required, a missing serial number or one in the wrong format, a missing manual or information notice, a missing, undrawn or incorrectly drawn EU declaration of conformity, missing or incomplete technical documentation, or missing manufacturer or importer name, trade name, trademark, website address or postal address; where it persists the Member State restricts or prohibits the making available or has the product withdrawn or recalled. Since 16 July 2021 the surveillance powers come from Regulation (EU) 2019/1020, whose authorities can demand documents and supply-chain information, inspect and acquire products, require corrective action, prohibit the making available and have products withdrawn, recalled or destroyed. In Denmark, Trafikstyrelsen supervises the product requirements under executive order nr. 1735 of 24 November 2020 and may demand access without a court order to business books, documents, information, business premises, storage and means of transport, take any product free of charge for testing, order the operator to warn users, stop misleading marketing, remedy the non-compliance, stop sales, withdraw, recall or destroy the product, order an online interface to change or remove content referring to it, act in the operator's place where it cannot be located or made to comply, and publish the measures; a fine is imposed on anyone who refuses access, withholds documents, refuses to hand over a product, fails to comply with an order or fails to report on the measures taken, with corporate liability under chapter 5 of the criminal code. Breaches of the Danish drone order supplementing Implementing Regulation (EU) 2019/947, including insurance, competency, distance and zone requirements, are likewise punishable by fine.

    Guide rebuilt on the SPEC-62 model from the consolidated text

    The guide was rewritten from the consolidated text of Delegated Regulation (EU) 2019/945 of 24 June 2025, the four amending acts, the consolidated text of Implementing Regulation (EU) 2019/947 of 1 May 2025, Regulation (EU) 2018/1139, Regulation (EU) 2019/1020, Regulation (EU) 2023/1230 and the Danish executive orders nr. 1735/2020, nr. 1649/2023 and nr. 527/2025. Two corrections to the previous version: the class system runs from C0 to C6, seven classes, not C0 to C4, because Delegated Regulation (EU) 2020/1058 added classes C5 and C6 and class C5 accessories kits from 9 August 2020; and Denmark's enforcement is Trafikstyrelsen on both sides, as the supervisory authority for the product requirements under executive order nr. 1735/2020 and as the competent authority for operations under executive order nr. 1649/2023, not only for operations and operator registration. The exact class limits, the conformity assessment routes and the cases where a notified body is needed, the noise test code and the Part 15 sound power limits, the marking and instruction requirements, the Article 39 list of formal non-compliance, the Article 40 certification conditions as rewritten in 2024, the remote identification add-on and the class C5 accessories kit now replace the earlier general description, and the market surveillance reference in Article 35 is read as Regulation (EU) 2019/1020.

Questions people ask about UAS

What are the drone classes C0 to C6 and what do they mean?

They are the seven class identification labels a UAS must bear to be operated in the open category or under an operational declaration in the specific category. Class C0 is below 250 g with a maximum level-flight speed of 19 m/s and a 120 m height limit; class C1 is below 900 g or transmits less than 80 J to a human head on impact at terminal velocity and adds direct remote identification, geo-awareness, night lighting, a low-battery warning and a sound power limit; class C2 is below 4 kg with a selectable low-speed mode of no more than 3 m/s and a command and control link protected against unauthorised access; class C3 is below 25 kg and less than 3 m in characteristic dimension; class C4 is below 25 kg with no automatic control modes beyond flight stabilisation and lost-link assistance; class C5, added in 2020, follows the class C3 requirements plus flight termination, a 5 m/s low-speed mode and link monitoring; and class C6 follows class C3 plus a 50 m/s ground speed limit, programmable operational volume limits and flight termination. Classes C0 and C1 fly in open subcategory A1, C2 in A2, and C2, C3 and C4 in A3, while C5 and C6 are the aircraft for standard scenarios STS-01 and STS-02 in the specific category.

Can I still sell or fly a drone without a C class label?

A drone without a class identification label and not privately built may only be flown in the open category if it was placed on the market before 1 January 2024, and then only in subcategory A1 if its maximum take-off mass including payload is below 250 g, or in subcategory A3 if it is below 25 kg including fuel and payload. The wider transitional rules of Article 22 of Implementing Regulation (EU) 2019/947, which allowed unlabelled aircraft up to 500 g, 2 kg and 25 kg under competency and distance conditions, ended on 31 December 2023. Because Article 4(1)(a) requires an open-category UAS to belong to one of the classes, to be privately built or to meet the Article 20 conditions, new units placed on the market from 1 January 2024 without a class label cannot lawfully be flown there, which is why retailers stopped listing them; Trafikstyrelsen ran a public campaign on the change and stresses that retailers are responsible for what they sell.

Do I need a notified body for my drone?

It depends on the class. Internal production control under Part 7 of the Annex, without a notified body, is available only when you assess a product against Parts 1, 5, 6, 16 or 17, that is classes C0, C4, C5 and C6 and remote identification add-ons, and only if you have applied harmonised standards for every requirement for which such standards exist. For classes C1, C2 and C3 you must use EU-type examination by a notified body followed by conformity to type based on internal production control under Part 8, or conformity based on full quality assurance under Part 9, which is closed to products that are toys within the meaning of Directive 2009/48/EC. The notified body's identification number goes after the CE marking only where Part 9 was used.

How does Regulation (EU) 2019/945 relate to Implementing Regulation (EU) 2019/947?

They are a pair adopted the same spring under Regulation (EU) 2018/1139: 2019/945 is the product law and 2019/947 is the operating law. 2019/945 sets what a drone must be, the class requirements, the conformity assessment, the CE marking and the class identification label, and the duties of manufacturers, authorised representatives, importers and distributors; 2019/947 sets the open, specific and certified categories, the subcategories A1, A2 and A3, remote pilot competency, operator registration, the UAS geographical zones, the operational authorisations, the standard scenarios STS-01 and STS-02 and the designation of national competent authorities. The bridge is the class label: the class a drone carries under 2019/945 decides which subcategory or standard scenario it may be used in under 2019/947, and Article 35(3) of 2019/945 requires market surveillance and border control authorities to cooperate with the authorities designated under Article 17 of 2019/947.

What else must a drone comply with besides the UAS Regulation?

Usually several acts at once. A UAS that is a toy within the meaning of Directive 2009/48/EC must also meet the toy directive, and a UAS that is not a toy must meet the relevant health and safety requirements of Directive 2006/42/EC for risks other than those linked to the safety of the flight, a reference that is read against Regulation (EU) 2023/1230 on machinery once the directive is repealed on 20 January 2027. Directive 2009/48/EC is in turn repealed by Regulation (EU) 2025/2509 on the safety of toys with effect from 1 August 2030, so from that date the toy references in Article 4(2), Article 13(2)(c) and point (10) of Part 1 of the Annex are read as references to the Toy Safety Regulation; toys placed on the market before then may still be made available and EC type-examination certificates run until 1 February 2031. Directive 2014/53/EU on radio equipment applies to unmanned aircraft that are not subject to certification, that are not intended to be operated only on frequencies allocated for protected aeronautical use and that intentionally emit or receive electromagnetic waves below 3 000 GHz, and Directive 2014/30/EU on electromagnetic compatibility applies where the radio directive does not. Where several Union acts require a declaration, a single EU declaration of conformity covers them all, and the CE marking stands for the whole set.

Who enforces the drone product rules in Denmark?

Trafikstyrelsen. Executive order nr. 1735 of 24 November 2020 on market surveillance of the drone area, in force since 1 January 2021 and issued under the aviation act, makes Trafikstyrelsen the supervisory authority for the product requirements of Delegated Regulation (EU) 2019/945 unless other legislation provides otherwise, and gives it the power to demand access without a court order to business books, documents, information, business premises, storage and means of transport, to take any product free of charge for testing and technical examination, to obtain expert opinions, to order warnings to users, an end to misleading marketing, remedial action, a stop to sales, withdrawal, recall or destruction, to order an online interface to change or remove content referring to a non-compliant drone, to act in the operator's place and to publish the measures. The same authority is the competent authority for drone operations under executive order nr. 1649 of 12 December 2023, which supplements Implementing Regulation (EU) 2019/947 and has applied since 1 January 2024. Drones are not one of the product areas of the Danish product act, so the market surveillance department of Erhvervsstyrelsen that took over Sikkerhedsstyrelsen's tasks in January 2026 has no role here.

What is a class C5 accessories kit?

A class C5 UAS may be built as such, or it may be a class C3 UAS fitted with an accessories kit that converts it into a class C5 one. Where the conversion route is used, the class C5 label must be affixed to every accessory in the kit, the kit may only convert a class C3 UAS that is not a fixed-wing aircraft unless tethered and that provides the necessary interfaces, and it must not change the software of the class C3 UAS. The kit may be placed on the market independently of the aircraft, in which case the manufacturer must place a single conversion kit on the market that does not alter the class C3 UAS compliance with Part 4, makes the converted UAS meet the additional class C5 requirements, and comes with instructions listing every class C3 UAS it fits and explaining installation and operation. For the operation to be lawful under standard scenario STS-01 the UAS must be accompanied by both EU declarations of conformity and carry the class C5 label.

Does the UAS Regulation apply to a drone I built myself or fly only indoors?

No to both, with one qualification. The regulation does not apply at all to UAS intended to be exclusively operated indoors, and a privately built UAS, meaning one assembled or manufactured for the builder's own use and not assembled from a ready-to-assemble kit placed on the market by a manufacturer, is excluded from the product chapter, so it carries no class label, no CE marking under this regulation and no EU declaration of conformity. A privately built aircraft may still be flown in the open category, in subcategory A1 below 250 g and in subcategory A3 below 25 kg, and where it is operated in the specific category below 120 metres it must carry a direct remote identification add-on meeting Part 6 of the Annex, whose own serial number is broadcast in place of the aircraft's. Military, customs, police, search and rescue, firefighting, border control and coastguard flights under the responsibility of a Member State fall outside the basic regulation altogether.
