What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 3(26) defines the market surveillance authority as the national authority carrying out the activities and taking the measures pursuant to Regulation (EU) 2019/1020.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

The confusion lies in distinguishing it from two other players. The notifying authority designates notified bodies and does no enforcement towards you; the Commission's AI Office supervises general-purpose AI models under Article 53, which has applied since 2 August 2025 and has been enforceable since 2 August 2026. The market surveillance authority is your actual enforcement contact point for AI systems: it can request technical documentation and logs, demand access to training and testing data sets, and restrict, withdraw or recall a system. The reference to Regulation (EU) 2019/1020 is not a formality, because through it the supervisor inherits a substantial toolkit of powers that did not need restating in the AI Act.

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

Record per AI system which market surveillance authority is competent (this differs per sector and per Member State where you offer it), who inside your organisation is the point of contact, and within how many working days you can supply the technical documentation, the logs and the data set descriptions. Rehearse that delivery once, because the deadline the supervisor sets is short.
