CE marking

## CE marking The CE marking is the conformity marking a manufacturer affixes to products covered by EU harmonisation legislation after completing the applicable conformity assessment procedure. It declares the product meets the essential requirements of all relevant EU directives and regulations, allowing sale throughout the European Economic Area. It is not a quality mark or a government approval. ### Key facts - "CE" stands for Conformité Européenne; the marking must follow a prescribed graphic form with exact proportions, and be visible, legible and indelible on the product or its data plate. - CE marking is required by more than 20 EU directives and regulations, including the Toy Safety Directive, EMC Directive, Low Voltage Directive, Radio Equipment Directive, Machinery Regulation and Medical Devices Regulation. - The manufacturer, or the authorised representative where one is designated, affixes the marking under its sole responsibility after completing conformity assessment. - Depending on the product's risk class, conformity assessment may be pure self-declaration or may require a notified body to examine the type, audit the quality system, or test production. - The marking must be accompanied by the EU declaration of conformity and a technical file kept available to market surveillance authorities for ten years. - Affixing CE marking to a product outside the scope of CE legislation, or to a non-compliant product, is an offence punishable under national law in each member state. - The CE marking is recognised in the EEA (EU plus Iceland, Liechtenstein and Norway); Turkey and some other countries also accept it under trade arrangements, while Great Britain now uses UKCA marking. ### What CE marking is CE marking is the visible endpoint of the EU's New Legislative Framework for product regulation. Each harmonisation directive or regulation sets "essential requirements" for health, safety and other public interests, and then defines conformity assessment procedures, the "modules", through which the manufacturer demonstrates compliance. The CE mark is the manufacturer's public statement that this process is complete and that the product satisfies every applicable instrument. The graphic itself is regulated: the letters C and E in a specific graduated design, with minimum height of 5 mm except for small products where the packaging or documents carry it. Where a notified body was involved in the production-control phase, its four-digit identification number follows the CE mark. These formalities matter because market surveillance officers check them during inspections; a misshapen logo or missing notified body number is treated as a formal non-compliance even if the product is technically safe. Crucially, CE marking is a manufacturer's declaration, not a government approval. No authority stamps the product before sale. The system relies on the manufacturer's conformity assessment, documented in the technical file, with market surveillance authorities checking compliance after products reach the market. This is why the documentation duties are as important as the mark itself: the mark without a valid technical file is an empty claim. ### Why it matters for market access CE marking is the single most important product compliance gate for the European market. Without it, a covered product cannot legally be placed on the EU market, and customs authorities can detain consignments at the border when the marking, declaration or labelling is missing or defective. For many product categories it is also the key to 30 countries at once: one conformity assessment opens the entire EEA. The marking drives the whole product development timeline. Because conformity assessment must be complete before the mark is affixed, and the mark before placing on the market, testing, risk assessment and documentation are critical-path activities, not end-of-project paperwork. Products that need notified body involvement face additional lead time: type examination queues, quality system audits and production testing can add months. Companies that discover CE requirements after tooling is cut frequently face redesigns, because essential requirements constrain design choices such as materials, guards, electrical clearances and software safety functions. CE marking also shapes commercial relationships. Importers must verify that the manufacturer carried out the conformity assessment, that the technical documentation can be made available, and that the product bears the marking and required labelling. Distributors must check the marking and documentation before making products available. A non-EU manufacturer therefore needs its importer relationships structured around compliance, not just logistics, and marketplace sellers need an EU economic operator behind the listing. ### Who it applies to CE marking applies to products falling within the scope of EU harmonisation legislation that provides for the marking. The main categories include: - Toys, under the Toy Safety Directive, with chemical, mechanical, flammability and electrical requirements. - Electrical and electronic equipment, under the Low Voltage Directive, EMC Directive and RoHS Directive, and radio equipment under the Radio Equipment Directive. - Machinery, now under the Machinery Regulation (EU) 2023/1230, which replaces the Machinery Directive. - Medical devices and in vitro diagnostics, under their respective regulations, with risk-class-dependent notified body involvement. - Personal protective equipment, gas appliances, pressure equipment, lifts, and construction products, each under sector legislation. - Ecodesign-covered products, where CE marking also signals compliance with energy and environmental requirements. The duty to affix the marking falls on the manufacturer. An importer who places a product on the market under its own name or trademark, or who modifies a product in a way that affects compliance, is legally considered the manufacturer and assumes the full duty. Distributors and importers who do not modify the product still have verification duties and must not make non-compliant products available. Products outside the scope of CE legislation, such as most general consumer goods covered only by the General Product Safety Regulation, must not bear the CE mark. Affixing it where no legislation provides for it is misleading and punishable. ### Requirements and the conformity assessment process The route to the CE mark follows a consistent sequence across sectors. 1. Identify applicable legislation. Determine every directive and regulation covering the product. A connected toy, for example, may fall under the Toy Safety Directive, the Radio Equipment Directive, the RoHS Directive and the Ecodesign framework simultaneously. Each applicable instrument must be satisfied before the mark is affixed. 2. Identify essential requirements and standards. Each instrument sets essential requirements; harmonised EN standards cited in the Official Journal give a presumption of conformity with the requirements they cover. Applying harmonised standards is voluntary but is the standard route; alternative technical solutions require the manufacturer to demonstrate equivalence. 3. Carry out conformity assessment. The applicable module depends on the product and its risk class. Module A (internal production control) allows self-assessment for low-risk products: the manufacturer tests, documents and declares. Higher-risk products require notified body involvement: EU type examination (Module B) plus production controls (Modules C to F), or full quality assurance (Module H). The choice is dictated by the legislation, not the manufacturer. 4. Compile the technical documentation. The technical file must enable assessment of conformity: design and manufacturing descriptions, risk assessments, lists of applied standards, test reports, and quality system evidence. It must be kept for ten years after the last product is placed on the market. 5. Draw up the EU declaration of conformity and affix the mark. The declaration identifies the product, the manufacturer, the applicable legislation and standards, and where relevant the notified body. Only then is the CE mark affixed, visibly, legibly and indelibly. 6. Maintain compliance. Design changes, new variants, updated standards and new legislation require reassessment. The declaration and technical file are living documents. | Module family | Notified body involvement | Typical use | |---|---|---| | A (internal production control) | None | Low-risk products, e.g. many EMC Directive products | | A1/A2 (supervised testing) | Product checks | Selected categories | | B + C/D/E/F (type examination + production) | Type approval plus production control | Machinery, medical devices, radio equipment | | G (unit verification) | Every unit examined | One-off or small-series high-risk products | | H (full quality assurance) | Quality system approval | Highest-risk categories | ### Market access relevance CE marking strategy should be set at product concept stage. The applicable legislation determines design constraints, testing budgets and launch timelines, and late discovery of an applicable directive is one of the most common causes of delayed European launches. A regulatory scoping exercise for each product family, mapping directives to requirements and modules, is inexpensive insurance. Testing and certification capacity should be booked early. Notified bodies in popular sectors operate waiting lists, and test laboratories need production-representative samples, which means the compliance schedule must align with the engineering build plan. Parallel testing to harmonised standards while design is finalised compresses the timeline. Documentation discipline is a competitive advantage. Market surveillance authorities increasingly request technical files electronically and on short deadlines; companies with organised, current files clear checks quickly, while companies that must reconstruct files under pressure face findings. For non-EU manufacturers, the authorised representative or EU importer should hold or have immediate access to the file. Finally, plan for the UK separately. Great Britain requires UKCA marking for most product categories, with its own designated standards and approved bodies. A product bound for both markets needs both conformity assessments, and labelling must carry both marks where both are claimed. ### Common misconceptions | Misconception | Reality | |---|---| | "CE marking means the product was approved by the EU." | It is the manufacturer's own declaration. No authority approves the product before sale; authorities check compliance through market surveillance. | | "CE stands for China Export." | There is no "China Export" mark. The CE graphic has legally defined proportions, and lookalike marks are treated as deceptive. | | "Our product is low risk, so we can skip the paperwork." | Even self-assessed products require a technical file, risk assessment and declaration. The paperwork is the compliance. | | "One CE mark covers all future variants." | Design changes and new variants require reassessment. The declaration must reflect the products actually placed on the market. | | "CE marking shows the product was made in Europe." | It indicates conformity with EU legislation, not origin. Products made anywhere can bear it if they comply. | | "We can affix the mark and finish testing later." | The mark may only be affixed after conformity assessment is complete. Premature marking is an offence. | ### Frequently asked questions How long does CE marking take? For self-assessed low-risk products with existing test data, weeks. For products requiring notified body type examination and quality system audits, typically three to nine months from engagement to marking, depending on sector queues and whether testing reveals design issues. How much does it cost? Self-assessment costs are mainly testing and engineering time. Notified body involvement adds certification fees that vary by sector and product complexity, from a few thousand euros for simple types to six figures for complex medical devices or machinery. Annual surveillance audits add recurring cost. Can we use test reports from a non-EU laboratory? Yes, if the laboratory is competent and the testing follows the applicable standards. The manufacturer remains responsible for the validity of the results. Notified bodies may require testing in accredited laboratories for the modules they oversee. What is the difference between CE and UKCA marking? CE marking is for the EU/EEA; UKCA is for Great Britain. The technical requirements are currently similar because UK designated standards mirror harmonised EN standards, but the legal regimes, marking rules and conformity assessment bodies are separate. Do we need to re-certify when a [harmonised standard](/glossary/harmonised-standard) is updated? When a standard's citation in the Official Journal is superseded, products assessed to the old version may lose presumption of conformity after the transition date. Manufacturers should monitor the Official Journal and reassess affected products. Who checks CE marking in practice? National market surveillance authorities in each member state, coordinated through EU networks, plus customs at the external border. Online marketplaces also face growing duties to check the compliance of products sold through their platforms. ### Sources - UK Government guidance on CE marking: https://www.gov.uk/guidance/ce-marking - European Commission, New Legislative Framework and the Blue Guide: https://single-market-economy.ec.europa.eu/single-market/goods/new-legislative-framework_en - Regulation (EU) 2019/1020 on market surveillance and compliance of products (EUR-Lex): https://eur-lex.europa.eu/eli/reg/2019/1020/oj/eng
