CE marking CE-jelölés

Short definition

The CE marking is the high-risk AI system provider's declaration that the system complies with the Regulation's requirements. It must be affixed, after the conformity assessment procedure is completed, visibly, legibly and indelibly to the system or its packaging, or — where this is not possible — to the accompanying documentation.

The rules on marking are set out in Article 48. Within the AI Act framework, the CE marking plays the same role as in other Union product-safety legislation: a declaration, made on the provider's own responsibility, of conformity, which the market surveillance authority may verify after the fact. Where the system is also subject to other Union legislation that likewise requires CE marking, a single marking indicates conformity with both sets of rules. Where a notified body has been involved, its identification number must also be affixed alongside the marking. Affixing the marking without authorisation — i.e. where a system bears the CE marking without the conformity assessment having actually taken place — can itself trigger a market surveillance measure and a penalty.

Why this matters for an EU SME

The CE marking may only be affixed once the conformity assessment has genuinely been completed — an SME becoming a provider should never treat this as a formality, since unauthorised affixing is itself a separate infringement.
