Regulation (EU) 2019/1020 gives market surveillance authorities investigation and enforcement powers for products covered by Union harmonisation legislation, including document requests, supply-chain questions, inspections, samples, online-interface measures, and corrective-action demands.
This page helps route authority requests to the right Article 4 contact, produce technical and supply-chain evidence, preserve records, and escalate serious-risk or persistent non-compliance findings.

An EU MSR investigation response should establish three points quickly: which product and Union harmonisation law are in scope, which is competent and which economic operator can answer, and what evidence supports conformity, risk assessment, corrective action, or escalation. For a covered product, identify the rather than relying on a seller, platform, or service address that has no documented Article 4 role. Authenticate the request, record the national or Union legal basis and stated deadline, and separate role evidence from technical proof. Regulation (EU) 2019/1020 sets minimum authority powers, while national law determines how those powers are exercised and which remedies apply.
Map products, Article 4 contacts, technical files, sample handling, corrective-action owners, and escalation records so EU MSR evidence requests can be answered from a controlled source of truth.
For products covered by Article 4, there must be an economic operator established in the Union responsible for the Article 4 tasks. That operator can be the EU manufacturer, importer, authorised representative with a written mandate, or EU fulfilment service provider where no EU manufacturer, importer, or authorised representative exists for the products it handles.
The Article 4 contact has operational duties beyond the contact details shown with the product. The role includes keeping the EU declaration of conformity or declaration of performance available where required, ensuring can be made available on request, providing information and documentation needed to demonstrate conformity, informing authorities when it has reason to believe the product presents a risk, and cooperating so corrective action is taken.
Do not treat every request as a routine document submission. Article 16 requires authorities to seek appropriate and proportionate corrective action when a product is liable to compromise protected interests or does not conform to applicable Union harmonisation legislation. Corrective action can include bringing the product into compliance, preventing availability, withdrawal, recall, destruction or inoperability, warnings, prior conditions, or alerts to end users. The last three options apply only where the product presents a risk in certain conditions or only to certain end users.
If a product presents a serious risk, Article 19 points to withdrawal, recall, or prohibition where there is no other effective way to eliminate the risk, and Article 20 requires rapid information exchange. Cross-border escalation can also arise when another Member State's authority needs information or enforcement measures, or when border authorities suspend release for free circulation because Article 4 contact details are missing, non-compliance is suspected, or a serious risk is suspected.
