EU CE Marking Framework
The conformity assessment and marking system that gates access to the European single market -- covering 25+ directives and regulations, from low-voltage electronics to medical devices to construction products.
CE marking is the legal ticket that lets a product be sold in Europe. It is not a quality seal or an award -- it is a declaration by the manufacturer that the product meets all the safety, health, and environmental requirements set by the EU directives that apply to it. Without it, a product covered by those directives simply cannot be placed on the European market. That market covers over 450 million consumers across 27 Member States plus the EEA countries.
The system works like this: manufacturers figure out which EU directives apply to their product (there may be several -- a wireless gadget could fall under the Radio Equipment Directive, the Low Voltage Directive, the EMC Directive, and RoHS simultaneously). They then test and assess the product against the essential requirements of each directive, prepare technical documentation proving compliance, and sign a Declaration of Conformity taking personal legal responsibility. For lower-risk products, the manufacturer can do all of this themselves. For higher-risk products -- pressure vessels, medical devices, equipment for explosive atmospheres -- an independent third party called a notified body must be involved.
The whole framework is built on Decision 768/2008/EC, which standardises the rules across all product sectors. It defines a menu of conformity assessment procedures, called modules A through H1, ranging from simple self-certification to full quality assurance with design examination by a notified body. Each product directive specifies which modules are available, and the choice depends on the level of risk the product poses.
Getting it wrong is not a bureaucratic inconvenience -- it is a legal violation. Market surveillance authorities across the EU can pull non-compliant products off shelves, block imports at the border, impose fines, and in cases of fraudulent marking, pursue criminal charges. The system is expanding too: from December 2027, the Cyber Resilience Act will require software products to carry CE marking for the first time, bringing an entirely new category of companies into the framework.
CE marking is not a quality mark -- it is a legal prerequisite for market access. Without it, products covered by applicable EU legislation cannot be legally placed on the single market, which represents over 450 million consumers and is the world's largest regulatory bloc for product safety. The marking declares that the manufacturer has assessed the product against all applicable essential requirements and takes responsibility for its conformity.
The system is built on the New Legislative Framework (NLF), adopted in 2008, which harmonises the conformity assessment infrastructure across all product sectors. Decision 768/2008 establishes a common menu of conformity assessment modules (A through H1), standardised definitions of economic operator obligations, and a uniform approach to market surveillance. Regulation 765/2008 sets the rules for accreditation of conformity assessment bodies and market surveillance coordination.
The framework is expanding. The Cyber Resilience Act will bring pure software products into the CE marking system for the first time from December 2027. The new Machinery Regulation modernises conformity assessment for AI-enabled and autonomous machines. The General Product Safety Regulation provides a safety net for risks not addressed by specific product legislation. Each expansion adds complexity: a single product may need to comply with three, four, or more directives simultaneously, each with its own essential requirements, harmonised standards, and conformity assessment procedures.
For manufacturers, the operational implications are significant. Technical documentation must be maintained for ten years (or longer under some directives). Notified body certificates have limited validity. Harmonised standards are revised regularly. Post-market obligations require ongoing monitoring, incident reporting, and corrective action capability. The cost of getting CE marking wrong -- market withdrawal, recalls, fines, reputational damage -- far exceeds the cost of doing it right.
The CE marking framework spans these core directives. Each sets its own essential requirements and conformity assessment procedures.
| REF. | DIRECTIVE / REGULATION | SCOPE | MODULE(S) | NB |

Decision 768/2008 defines a standardised menu of modules. The applicable directive specifies which modules are available for each product category.
Internal production control
Manufacturer self-assesses conformity. Prepares technical documentation, ensures production conformity, draws up DoC, and affixes CE marking. No notified body involvement.
Low-risk products: consumer electronics (LVD, EMC), toys, simple electrical equipment
The DoC is a legal document signed by the manufacturer, declaring that the product meets all applicable EU requirements. It must accompany the product or be available on request.
The DoC must cover all applicable directives in a single document. Where different directives require different information, the DoC must include all required elements. The manufacturer (or authorised representative) must retain the DoC for at least 10 years after the product is placed on the market.
Notified bodies are third-party conformity assessment organisations designated by EU Member States. They are required when the applicable directive mandates independent verification.
Notified bodies are designated by the national authority (Notifying Authority) of an EU Member State and notified to the European Commission. They are listed in the NANDO database.
Typically accredited by the national accreditation body (e.g., DAkkS in Germany, UKAS in UK) under EN ISO/IEC 17065 (product certification), 17025 (testing), or 17021 (management systems).
Examines a representative specimen (type) of the product and assesses whether it meets the essential requirements. Issues an EU type-examination certificate (Module B).
Monitors the manufacturer's quality management system and/or conducts periodic or unannounced inspections during production (Modules D, E, H).
Tests and verifies every product or a statistical sample against the approved type or applicable requirements (Modules F, G).
Issues, suspends, withdraws, or restricts certificates based on ongoing compliance. Must notify the Commission and other notified bodies of certificate changes.
Must be independent from the manufacturer. Cannot provide consultancy to manufacturers on how to achieve compliance and then certify the same products.
Since Brexit, the UK operates a parallel conformity marking system. This comparison reflects the status as of 2026.

|---|---|---|
| Territory | EU 27 Member States, EEA (Norway, Iceland, Liechtenstein), Turkey, Switzerland (partial) | Great Britain (England, Scotland, Wales). Northern Ireland uses CE marking under the Windsor Framework. |
| Legal basis | New Legislative Framework (Regulation 765/2008, Decision 768/2008) | UK Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019. Based on pre-Brexit EU law, separately maintained. |
| Conformity assessment | EU harmonised standards; conformity assessment by EU-notified bodies | UK designated standards (initially identical to EU); conformity assessment by UK-approved bodies |
| Notified / Approved bodies | Notified bodies designated by EU Member States and listed in the NANDO database | UK-approved bodies designated by UKAS (UK Accreditation Service). EU notified body certificates not accepted. |
| Declaration of conformity | EU Declaration of Conformity referencing EU directives/regulations | UK Declaration of Conformity referencing UK statutory instruments (SI equivalents of EU directives) |
| Marking requirements | CE marking: minimum 5mm height, proportional, visible, legible, indelible | UKCA marking: minimum 5mm height, separate symbol from CE. Both markings may appear on the same product for dual market access. |
| Importer obligations | EU-based importer or authorised representative required since Market Surveillance Regulation 2019/1020 | UK-based importer required. Product must bear the name and address of a UK economic operator. |
| Current status (2026) | Fully operational. Continuously updated with new legislation (CRA, new Machinery Regulation). | UK extended CE marking recognition indefinitely in most sectors (announced Dec 2024). UKCA marking remains available as an alternative. |
| Transition provisions | No transition -- CE marking is the established EU system | UK recognises CE marking for most product categories without end date. Products can use CE, UKCA, or both. |
