Colorado ADMT rules: hearing and last day for written comments · Oct 26, 2026 · See what changes
A formal document in which the provider of a high-risk AI system declares that the system complies with the EU AI Act. By signing the Declaration of Conformity, the provider takes legal responsibility for compliance. The declaration must be kept on file and made available to authorities. It is distinct from a conformity assessment (the process of checking compliance) — the declaration is the formal statement that the check has been completed and the system complies. CE marking can only be affixed after the declaration is signed.
Why this matters for your team
Signing the Declaration of Conformity is the legal moment when you formally accept responsibility for EU AI Act compliance. Don't sign it until your conformity assessment documentation is complete — it creates legal liability you cannot walk back.
