EMC in plain terms
The Electromagnetic Compatibility Directive (EMC Directive), formally Directive 2014/30/EU, regulates the electromagnetic compatibility of equipment. Its aim is to ensure the functioning of the internal market by requiring equipment to comply with an adequate level of electromagnetic compatibility (Art. 1), which the directive defines as the ability of equipment to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to other equipment (Art. 3(1), point (4)). Two essential requirements carry the whole directive: emissions must stay below the level that stops radio, telecommunications or other equipment working as intended, and immunity must be high enough for the equipment to keep working without unacceptable degradation in the disturbance expected in its intended use (Annex I, point 1).
The 2014 text is a recast of Directive 2004/108/EC aligned with the New Legislative Framework, adding the economic operator duties, traceability and market surveillance procedures shared with the Low Voltage and Radio Equipment Directives. As a directive it works through national law: Member States had to transpose it by 19 April 2016 and apply it from 20 April 2016 (Art. 44 and Art. 45).
Official text Read the directive on EUR-Lex: Directive 2014/30/EU (CELEX 32014L0030), or the consolidated text of 30 May 2026 that includes the aviation amendment and the internal market emergency procedures.
Scope
The directive applies to equipment, meaning any apparatus or fixed installation (Art. 2(1) and Art. 3(1), point (1)). Apparatus is any finished appliance or combination of appliances made available on the market as a single functional unit for the end user that is liable to generate electromagnetic disturbance or whose performance is liable to be affected by it; components and sub-assemblies intended for incorporation by the end user, and mobile installations intended to be moved and operated in a range of locations, count as apparatus (Art. 3(1), point (2), and Art. 3(2)). A fixed installation is a particular combination of apparatus and other devices assembled, installed and intended for permanent use at a predefined location (Art. 3(1), point (3)).
Five groups are excluded: radio equipment, which the Radio Equipment Directive covers with its own EMC essential requirement; aviation equipment within Regulation (EU) 2018/1139 intended exclusively for airborne use; radio amateur equipment not made available on the market; equipment whose physical characteristics make it inherently incapable of exceeding acceptable emissions and immune to the disturbance of its intended use; and custom-built evaluation kits for research and development (Art. 2(2); Directive 2014/53/EU, Art. 3(1)(b)). Where other Union legislation lays down the essential requirements more specifically for particular equipment, the directive ceases to apply to that equipment for those requirements (Art. 2(3)), and it does not affect legislation on the safety of equipment (Art. 2(4)).
The duties fall on the economic operators: manufacturer, authorised representative, importer and distributor (Art. 3(1), point (15)), with Member States identifying the person responsible for a fixed installation (Art. 19(3)). A manufacturer is whoever manufactures apparatus or has it designed or manufactured and markets it under his own name or trade mark (Art. 3(1), point (11)), and an importer or distributor that sells under its own brand or modifies apparatus in a way that may affect compliance takes on the manufacturer’s obligations (Art. 11).
What you must do
Essential requirements and harmonised standards
Equipment must meet the Annex I essential requirements (Art. 6): emissions below the level that prevents other equipment from operating as intended, and immunity sufficient to operate without unacceptable degradation, both judged with regard to the state of the art. A fixed installation must in addition be installed applying good engineering practices and respecting the information on the intended use of its components (Annex I, point 2). Equipment that conforms to harmonised standards, or parts of them, whose references are published in the Official Journal is presumed to conform to the requirements those standards cover (Art. 13). Member States may still take special measures to overcome an EMC problem at a specific site or to protect public telecommunications networks and safety-related stations, and must notify them to the Commission (Art. 5(2)).
Conformity assessment, technical documentation and CE marking
Compliance of apparatus is demonstrated either by Module A internal production control under Annex II or by EU-type examination followed by conformity to type based on internal production control under Annex III, and the manufacturer may restrict the notified-body route to some aspects of the essential requirements while using Module A for the rest (Art. 14). Under Module A the manufacturer performs an electromagnetic compatibility assessment of the apparatus on the basis of the relevant phenomena, covering all normal intended operating conditions and every configuration identified as representative of its intended use (Annex II, point 2), establishes technical documentation with a risk analysis, drawings, the standards applied or the solutions adopted, calculations and test reports (Annex II, point 3), keeps manufacturing in conformity (Annex II, point 4), affixes the CE marking to each item and draws up a written EU declaration of conformity for the apparatus model, keeping both for 10 years (Annex II, point 5).
The EU declaration of conformity follows Annex IV, is translated into the languages the Member State requires, is kept up to date and, where several Union acts require a declaration, is a single declaration covering them all (Art. 15). The CE marking is subject to the general principles of Regulation (EC) No 765/2008 and is affixed visibly, legibly and indelibly to the apparatus or its data plate before placing on the market, or to the packaging and accompanying documents where the nature of the apparatus does not allow it (Art. 16 and Art. 17).
Information, instructions and traceability
The apparatus carries a type, batch or serial number and the manufacturer’s name and single postal contact address; importers add their own (Art. 7(5), 7(6) and 9(3)). Instructions in the language the Member State determines must state the specific precautions to take when assembling, installing, maintaining or using the apparatus so that it stays compliant, give the information needed to use it as intended and, where compliance is not ensured in residential areas, indicate that restriction clearly, where appropriate also on the packaging (Art. 7(7) and Art. 18). All operators identify their suppliers and customers for 10 years (Art. 12).
Fixed installations
Apparatus made available on the market that may be incorporated into a fixed installation must comply as apparatus. For apparatus intended for incorporation into a particular fixed installation and not otherwise made available, Articles 6 to 12 and 14 to 18 are not compulsory, provided its documentation identifies the installation and its EMC characteristics, the precautions for incorporation and the manufacturer’s and importer’s identification (Art. 19(1)). The good engineering practices applied to the installation are documented and held by the person responsible at the disposal of the national authorities for as long as the installation is in operation. Where there are indications of non-compliance, in particular complaints about disturbance, the competent authorities may request evidence of compliance, initiate an evaluation and impose measures to bring the installation into compliance (Art. 19(2)).
Obligations by role
Manufacturers design and manufacture to the essential requirements, assess, document and declare conformity, affix the CE marking, keep the documents for 10 years, keep series production in conformity, mark the apparatus with an identifier and their name and address, supply instructions and the Article 18 information, take corrective action and inform the authorities of risks, and cooperate on request (Art. 7). Authorised representatives act under a mandate that must at least cover keeping the documents and cooperating with authorities, and cannot take over design or documentation duties (Art. 8). Importers place only compliant apparatus on the market, verify the manufacturer’s work, add their own name and address, ensure instructions in the required language, protect the apparatus in storage and transport, take corrective action and keep the declaration for 10 years (Art. 9). Distributors verify the CE marking, documents, language and markings before making apparatus available, protect it in storage and transport and see that corrective action is taken (Art. 10). Importers and distributors that sell under their own brand or modify apparatus become manufacturers (Art. 11).
Emergency procedures from 30 May 2026
Directive (EU) 2024/2749 inserted Chapter 5a. Articles 40b and 40c apply only to apparatus designated as crisis-relevant goods, only while an internal market emergency mode under Regulation (EU) 2024/2747 is active and only after the Commission has adopted the corresponding implementing act (Art. 40a). During such a period the Commission may list standards or establish common specifications that give a presumption of conformity where harmonised standards are missing or cannot be used, and Member States prioritise market surveillance of the listed apparatus and assist one another (Art. 40b and Art. 40c).
Enforcement and penalties
Market surveillance follows Regulation (EU) 2019/1020 (the directive’s Article 37 cites Regulation (EC) No 765/2008, whose surveillance chapter that regulation replaced on 16 July 2021). Where an authority has sufficient reason to believe that apparatus presents a risk to the public interests the directive protects, it evaluates the apparatus, requires corrective action, withdrawal or recall within a period commensurate with the risk and, if the operator does not act, prohibits or restricts the making available, withdraws or recalls the apparatus and informs the Commission and the other Member States (Art. 38). The Commission decides disputed national measures through the Union safeguard procedure (Art. 39). Formal non-compliance, such as missing or wrongly affixed CE marking, a missing or incorrect declaration, incomplete technical documentation or missing identification and address information, must be ended and otherwise leads to restriction, prohibition, withdrawal or recall (Art. 40), and non-compliant fixed installations are brought into compliance by the measures the competent authority imposes (Art. 19(2)).
Penalties are set nationally: Member States lay down effective, proportionate and dissuasive penalties for infringements of their transposing laws, which may include criminal penalties for serious infringements (Art. 42). In Denmark, the directive is implemented through the act on radio equipment and electromagnetic compatibility (lovbekendtgørelse nr. 958 of 22 June 2022) and executive order nr. 1107 of 6 November 2019; Sikkerhedsstyrelsen, which since January 2026 is a department of Erhvervsstyrelsen (the Danish Business Authority) named Markedsovervågning, controls the products on behalf of Styrelsen for Dataforsyning og Infrastruktur, which holds the sector responsibility.
