CECheck The reference for CE marking

What is CE marking?

Last reviewed: May 2026 · Legal status verified against EUR-Lex.

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:

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:

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:

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:

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.

Single CE mark, multiple obligations. One mark is affixed regardless of how many acts apply. The Declaration of Conformity, the technical documentation, and the conformity assessment route may differ act by act, but the visible mark on the product is one and the same graphic.

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

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.
