EU AI Act Art. 43Conformity assessment

Article 43 sets the pre-market exam for high-risk AI. Most Annex III systems self-assess via internal control; biometrics and remote biometric identification need third-party assessment by a notified body — unless fully harmonised standards apply.

At a glance

What this article requires

  • Annex III points 2–8 (most high-risk areas): internal control (Annex VI) — the provider self-assesses.
  • Annex III point 1 (biometrics, incl. remote biometric identification): third-party assessment under Annex VII, unless the provider fully applies harmonised standards.
  • For Annex I products (e.g. medical devices, machinery), the AI Act assessment integrates with the product's existing conformity procedures.
  • Substantial modifications trigger a fresh conformity assessment.

Scope

Who this applies to

Providers of high-risk AI. Deployers must verify that a vendor's system carries a completed conformity assessment before procurement.

Obligations

What you must actually do

Pick the right route early

Biometric and remote-biometric-ID systems need a notified body; misrouting wastes months of lead time.

Document the internal control

Even self-assessment requires the full Annex VI evidence: technical documentation, QMS, and a declaration that the system meets the requirements.

Re-assess on substantial change

Change the intended purpose or materially modify the system, and the assessment must be re-run.

Action plan

Practical first steps

  1. 1

    Classify your system (Art. 6) and confirm which route applies before starting development.

  2. 2

    For third-party routes, line up a notified body early — capacity is limited.

  3. 3

    Build the evidence pack in parallel with development so the assessment is a formality, not a rescue.

Penalty exposure

Conformity-assessment failures sit in the general tier: up to €15 million or 3% of global annual turnover.

FAQ

Questions about Art. 43

Can I self-certify my high-risk system?

For most Annex III categories, yes — internal control under Annex VI. For biometrics and remote biometric identification under Annex III point 1, you need third-party assessment unless you fully apply harmonised standards.

What is a notified body and when do I need one?

A notified body is a designated conformity-assessment organisation. You need one for biometrics (Annex III point 1) and for Annex I products where sectoral law requires third-party assessment.
