CE marking for AI
The CE marking on a high-risk AI system is the provider's visible declaration that the system conforms to the EU AI Act. Governed by Article 48, it is affixed only after conformity assessment is passed and the EU declaration of conformity (Article 47) is drawn up, signalling the system may lawfully be placed on the EU market.
What CE marking signifies
For high-risk AI systems, the CE marking is the outward sign that the provider has met the substantive requirements of Articles 9 to 15, passed the relevant conformity assessment (Annex VI or Annex VII), and prepared the EU declaration of conformity under Article 47. It must be affixed visibly, legibly, and indelibly, and for digital systems may be provided in electronic form. Where a notified body was involved, its identification number accompanies the mark.
Who affixes it and when
- Only providers of high-risk AI systems affix the CE marking, not deployers.
- It is affixed before the system is placed on the EU market or put into service.
- It comes after conformity assessment, the declaration of conformity (Article 47), and registration in the EU database (Article 71).
- A substantial modification can require a fresh assessment before the marking remains valid.
- Most high-risk obligations apply from 2 August 2026, with high-risk AI in regulated products from 2 August 2027.
