What is CE marking?
CE marking is a declaration by the manufacturer that a product meets every requirement of the EU harmonisation legislation that applies to it. It is not a certificate, not a quality mark, and not an indication of origin. The letters "CE" stand for Conformité Européenne. The mark's legal function — and its limits — are defined in Regulation (EC) No 765/2008 and Decision No 768/2008/EC, together with each applicable product-specific directive or regulation.
Affixing CE marking creates a legal claim. By marking a product, the manufacturer takes responsibility for its compliance with every applicable act. Affixing the mark to a product not covered by such legislation — or to one that does not meet the requirements — is itself an infringement, with consequences described in penalties for incorrect CE marking.
Legal basis
Two horizontal legal instruments define CE marking generically:
- Regulation (EC) No 765/2008 on accreditation and market surveillance. Article 30 sets out the general principles of CE marking: who may affix it (only the manufacturer or authorised representative), what it signifies (the product's conformity with the applicable Union harmonisation legislation providing for its affixing), and the prohibition on affixing marks that could mislead third parties as to its meaning.
- Decision No 768/2008/EC on a common framework for the marketing of products. Annex I contains the reference provisions that EU harmonisation acts use when they require CE marking — including the wording of manufacturer obligations, conformity assessment modules, and the rules on affixing the mark.
These two acts form part of the New Legislative Framework, the modular structure used by EU harmonisation law since 2008. They do not themselves require CE marking on any particular product — that requirement comes from each sectoral directive or regulation. A product needs CE marking only when a specific act says so. There is no general obligation to CE-mark goods sold in the EU.
The Commission's own interpretation of these rules is published as the Blue Guide, currently in its 2022 edition (Commission Notice C/2022/3637, OJ C 247, 29.6.2022, p. 1). The Blue Guide is not legally binding but is treated as authoritative by Member State authorities.
What CE marking signifies
Under Article 30(3) of Regulation 765/2008, by affixing the CE marking the manufacturer:
- indicates that they take responsibility for the conformity of the product with every applicable requirement in the relevant Union harmonisation legislation;
- indicates that the applicable conformity assessment procedure has been completed;
- where that procedure required the intervention of a Notified Body, that the body's role in the production-control phase is reflected by the addition of its four-digit identification number next to the mark.
The legal effect is that the marked product benefits from the principle of free movement within the European Economic Area: Member State authorities must not restrict its placing on the market on grounds covered by the harmonising act, unless they can show non-compliance.
What CE marking is not
The mark is widely misunderstood, and several misreadings recur in market surveillance reports and customs disputes. CE marking is not:
- A quality mark. The applicable legislation defines minimum safety, health, environmental, and consumer-protection requirements. A CE-marked product meets those minima; it is not certified to be superior, durable, or fit for any particular purpose.
- A certification. The mark is affixed by the manufacturer, not issued by a third party. Even when a Notified Body has been involved, the body issues a certificate (for example an EU type-examination certificate); it does not issue the CE mark.
- An indication of EU origin. A product manufactured in China, Vietnam, or the United States and conforming to the applicable EU acts bears CE marking in exactly the same way as a product made in Germany. Country-of-origin marking is governed by separate customs and consumer-protection rules.
- An environmental or ethical label. Apart from specific environmental requirements in acts such as RoHS Directive 2011/65/EU or the Ecodesign Regulation 2024/1781, CE marking carries no general statement about a product's environmental impact, supply-chain practices, or sustainability.
- The "China Export" mark. The persistent claim of an unofficial "CE" mark standing for "China Export" — supposedly distinguished by narrower letter spacing — has no basis in any EU document and is rejected by the Commission. There is one CE mark, defined by the graphic in Annex II of Regulation 765/2008.
Scope: which products require CE marking
A product requires CE marking only when at least one EU harmonisation act in force lists it within scope and mandates the affixing of the mark. The full set of such acts — currently around 25 — covers categories including machinery, electrical equipment, radio equipment, toys, personal protective equipment, medical devices, pressure equipment, construction products, lifts, gas appliances, recreational craft, and measuring instruments.

Products outside the CE system
Several large categories of regulated products do not bear CE marking even though they are tightly regulated under EU law:
- Food, feed, and tobacco products: regulated under separate EU food law (Regulation (EC) No 178/2002 and successors). No CE marking applies.
- Medicinal products: authorised under Directive 2001/83/EC and Regulation (EC) No 726/2004. Medical devices are CE-marked under the Medical Devices Regulation (EU) 2017/745, but medicines are not.
- Cosmetics: governed by Regulation (EC) No 1223/2009, which does not provide for CE marking.
- Motor vehicles: type-approved under Regulation (EU) 2018/858 rather than CE-marked. Vehicle components may carry "e" or "E" approval marks.
- Chemicals: regulated under REACH (Regulation (EC) No 1907/2006) and CLP (Regulation (EC) No 1272/2008); no CE marking.
The general rule is therefore: assume a product is outside the CE system until you can identify a specific harmonisation act that places it inside.
Products requiring multiple acts
A product is frequently covered by more than one harmonisation act, and each applies in full. A cordless drill, for example, sits within the scope of the Machinery Regulation (EU) 2023/1230, the EMC Directive 2014/30/EU, the Radio Equipment Directive 2014/53/EU (where it contains a wireless module), the RoHS Directive 2011/65/EU, and the Battery Regulation (EU) 2023/1542. The single CE mark on the product signifies conformity with all of them. The EU Declaration of Conformity must list every applicable act.
Geographic scope
CE marking is required for products placed on the market in the 27 EU Member States. By virtue of the EEA Agreement, it is also required and recognised in Iceland, Liechtenstein, and Norway. Switzerland recognises CE marking for products covered by its Mutual Recognition Agreement with the EU, sector by sector. Turkey applies the CE system to most harmonised product categories through its Customs Union arrangement.
The United Kingdom recognises CE marking indefinitely in Great Britain for 21 product regulations under the Product Regulation and Metrology Act 2025 and associated regulations; the UKCA mark remains optional rather than required for those categories. Northern Ireland continues to apply EU rules under the Windsor Framework. See CE marking vs UKCA for the current allocation by sector.
Who affixes the mark
Only the manufacturer or an authorised representative acting under written mandate may affix CE marking (Regulation 765/2008, Article 30(1)). For products imported from outside the EU, the manufacturer remains the responsible party for the marking; the EU importer verifies that the marking is present, the technical documentation exists, and contact information is on the product. An importer who places a product on the market under its own name or trademark, or modifies a product already placed on the market in a way that affects its compliance, is treated as the manufacturer (Decision 768/2008/EC, Article R6).
Distributors do not affix the mark and are not responsible for the underlying conformity assessment, but they must verify before sale that the mark is present and that documentation is in order (distributor obligations).
Form of the mark
The exact graphic of the CE mark is defined in Annex II of Regulation 765/2008. The two letters must be drawn with the proportions shown in that annex (each letter is constructed within a notional grid, with the "C" and "E" of equal height and a fixed gap between them). The minimum height is 5 mm unless a specific act provides otherwise; the mark must be visible, legible, and indelible (affixing the CE mark). Where it cannot be applied to the product itself because of the product's nature, it is placed on the packaging and accompanying documents.
Common errors
- Affixing CE marking without identifying the applicable acts. Many small manufacturers apply the mark on the assumption that "EU sale = CE required." If no harmonising act covers the product, the mark must not be applied; doing so is an infringement under Article 30(2) of Regulation 765/2008.
- Treating CE as a substitute for GPSR conformity. Since 13 December 2024, the General Product Safety Regulation (EU) 2023/988 applies to all consumer products not specifically covered by harmonisation legislation. A non-CE consumer product is not unregulated — it falls under GPSR. Conversely, a CE-marked consumer product still needs to comply with GPSR provisions on traceability and recalls where the sectoral act does not cover them.
- Mixing CE with adjacent marks. CE is not interchangeable with UKCA (Great Britain), EAC (Eurasian Economic Union), FCC (United States radio compliance), or the China Compulsory Certification mark (CCC). Each scheme operates under separate law.
- Affixing the Notified Body number when no body was involved. The four-digit identifier appears next to the CE mark only when a Notified Body has intervened in the production-control phase of the applicable conformity assessment module. For products certified under Module A (internal production control), no number is added.
- Using non-compliant CE mark graphics. Annex II of Regulation 765/2008 specifies the proportions. Marks drawn with distorted letter forms, unequal heights, or insufficient size do not satisfy Article 30(4) and may be challenged.
Relationship to conformity assessment
CE marking is the visible end-point of the conformity assessment process. The process itself — risk analysis, application of harmonised standards, testing, technical documentation, drawing up the EU Declaration of Conformity — is described in the CE marking process. The choice of which conformity assessment route to follow depends on the product category and risk class and is covered in conformity assessment modules.
Relationship to harmonised standards
A manufacturer may demonstrate conformity with essential requirements by applying harmonised standards whose references have been published in the Official Journal of the European Union. Doing so produces a presumption of conformity with the requirements the standard covers. Use of harmonised standards is voluntary; alternative technical solutions are permitted provided the manufacturer can demonstrate that essential requirements are met.
