CE Marking: What It Requires and Who Is Responsible

If you sell products on the European market, CE marking is likely one of the most important compliance topics you need to address. The CE mark is not just a symbol – it is your declaration that the product meets the applicable EU requirements for safety, health and the environment. In this guide, we review what CE marking actually entails, who bears the responsibility, and which steps you need to go through to achieve it.

What Is CE Marking?

CE stands for Conformit Europenne and is the EU’s harmonised marking system. When you affix the CE mark to your product, you as an economic operator declare that the product meets all relevant requirements in the EU directives and regulations that apply to the product category in question.

The CE mark is not a quality stamp in the traditional sense. It is a legal obligation and a prerequisite for the product to be freely traded within the entire EEA area. Without the correct CE marking, you risk your product being stopped at the border, withdrawn from the market or triggering fines and sanctions. Read about the consequences of non-compliance to understand what can specifically happen.

Which Products Require CE Marking?

CE marking is not relevant for all products. It applies to product categories covered by specific EU directives or regulations. Among the most common are:

• Machinery Directive (2006/42/EC): Machinery and safety components.
• Low Voltage Directive (2014/35/EU): Electrical equipment designed for use at voltages between 50 and 1000 V AC.
• EMC Directive (2014/30/EU): Electromagnetic compatibility for electronic devices.
• Toy Safety Directive (2009/48/EC): Toys intended for children under 14 years.
• Construction Products Regulation (305/2011): Construction products.
• Medical Devices Regulation (MDR 2017/745): Medical devices and in vitro diagnostics.
• Radio Equipment Directive (2014/53/EU): Wireless equipment and radio communication.

If your product falls under one or more of these directives, CE marking is a legal requirement – not an option.

Who Is Responsible?

A central question is who actually bears the responsibility for CE marking. The answer depends on your role in the supply chain.

The Manufacturer

The manufacturer has the primary responsibility. It is the manufacturer who must ensure that the product is designed and manufactured in conformity with the relevant directives. The manufacturer must carry out or commission the necessary conformity assessment, prepare technical documentation and issue the EU Declaration of Conformity (DoC). It is also the manufacturer who physically affixes the CE mark to the product.

The Importer

If you import products from countries outside the EEA, you assume an independent responsibility. You must verify that the manufacturer has carried out the correct conformity assessment, that the technical documentation exists, and that the product bears the correct CE mark. You must also be able to present the declaration of conformity to market surveillance authorities if they request it.

The Distributor

As a distributor, you are not obliged to prepare documentation, but you must exercise due diligence. This means you must verify that the product bears the CE mark, that the necessary documents accompany the product, and that there are no obvious signs of non-conformity. If you sell a product that you know or should know does not meet the requirements, you can be held liable.

Step by Step: From Directives to CE Mark

The process of CE marking your product may seem complex, but it follows a logical sequence. Here are the key steps:

1. Identify Relevant Directives and Harmonised Standards

Start by determining which EU directives and regulations apply to your product. A product may be covered by multiple directives simultaneously – for example, an electronic device may be covered by both the Low Voltage Directive, the EMC Directive and the RoHS Directive. Each directive typically has associated harmonised standards (EN standards) that specify the technical requirements you must meet.

2. Assess Product Conformity

Carry out a risk assessment and test your product against the relevant harmonised standards. For some product categories, you can perform this assessment yourself (internal production control). For others – such as medical devices or pressure equipment – the involvement of a Notified Body is required.

3. Prepare Technical Documentation

Your technical documentation is the core of CE marking. It must document that the product meets all applicable requirements, and it must be available to the authorities for at least 10 years after the product has been placed on the market. The documentation should typically include a product description, design drawings, risk assessments, test reports, and a list of the harmonised standards applied. See our guide to audit-ready documentation to ensure your documentation stands up to authority inspection.

4. Issue the EU Declaration of Conformity (DoC)

The Declaration of Conformity is a legal document in which you as the manufacturer (or authorised representative) declare that the product meets the applicable requirements. The DoC must contain:

• Name and address of the manufacturer.
• Unique identification of the product (type, batch, serial number).
• A list of the directives and harmonised standards the product has been assessed against.
• Date and signature of a responsible person.

The declaration must be drawn up in at least one of the official EU languages and made available to the end user or authorities.

5. Affix the CE Mark

Once the documentation is in place and the declaration of conformity has been issued, you can affix the CE mark to the product. The mark must be visible, legible and indelible. It must have a minimum height of 5 mm and maintain the correct proportions in accordance with EU guidelines. If a Notified Body has been involved, the body’s identification number must be placed next to the CE mark.

The Declaration of Conformity in Practice

Many businesses underestimate the importance of the Declaration of Conformity. It is not a document you fill out once and forget. If you make changes to the product’s design, materials or manufacturing process, you must assess whether the change affects conformity – and whether the declaration needs to be updated. Likewise, you must monitor changes to applicable directives and standards, as these may mean your product is no longer in conformity.

How Conphora Automates the CE Marking Process
