- The Blue Guide explains product-law evidence concepts such as technical files, EU declarations, importer good practice, and reasoned authority requests.
"technical file on request"
The MSR is not just an enforcement-law backdrop. For covered harmonised products, it creates practical requirements around an EU-established Article 4 operator, online and distance sales, cooperation with authorities, documentation access, border controls, corrective action, serious-risk escalation, and EU information systems.
Use this page to build a requirements register that product, regulatory, logistics, marketplace, and support teams can actually use when placing or making products available in the EU.

EU Market Surveillance Regulation requirements start with a product-and-role question: is the product subject to Union harmonisation legislation covered by the MSR, is it being placed or made available on the Union market, and who is the EU-established operator that can respond when authorities ask for conformity evidence or corrective action?
For products covered by Article 4, the product may be placed on the EU market only when there is an economic operator established in the Union responsible for the Article 4 tasks. That operator can be an EU manufacturer, an importer where the manufacturer is outside the EU, an authorised representative with a written mandate, or an EU fulfilment service provider for products it handles when none of the other listed operators is established in the Union.
The requirement is operational, not just contractual. The Article 4 operator must verify that required EU declarations or declarations of performance and technical documentation have been drawn up, keep the declaration available for the period required by the applicable product law, make technical documentation available on request, provide information in a language easily understood by the authority, inform authorities when it has reason to believe the product presents a risk, and cooperate on immediate corrective action or risk mitigation.
Article 6 treats products offered online or through other distance-sales channels as made available on the market when the offer is targeted at end users in the Union. Recital 15 explains that targeting depends on the facts, such as dispatch areas, ordering language, and payment means; mere website accessibility in a Member State is not enough by itself.
Online requirements therefore belong in the same MSR register as physical distribution. Product pages, marketplace listings, checkout flows, fulfilment routes, and after-sale support can all affect whether an offer is directed to EU end users and whether the responsible operator and documentation path are ready before the sale is made.
Turn Article 4 operator coverage, technical documentation, authority requests, border holds, corrective action, and serious-risk escalation into a product-level evidence workflow.
Products entering the Union market for release for free circulation are subject to controls by designated authorities based on risk analysis. Release can be suspended when required documentation is missing or doubtful, marking or labelling is not compliant, CE or other required marking is false or misleading, Article 4 operator contact details are not indicated or identifiable, or there is cause to believe the product is non-compliant or presents a serious risk.
A border response file should therefore connect customs data, product identity, Article 4 operator details, declaration and technical-documentation status, labelling evidence, shipment route, and the decision trail from the market surveillance authority. Release for free circulation after a suspension is not proof of conformity, so the compliance record still needs to be closed on substance.
Where a product is liable to compromise protected interests or does not conform to applicable Union harmonisation legislation, market surveillance authorities must require appropriate and proportionate corrective action within a period they specify. Corrective action can include bringing the product into compliance, stopping availability, withdrawal or recall, public risk alerts, destruction or rendering inoperable, warnings, prior conditions for availability, or immediate end-user alerts.
For serious risk, authorities must ensure withdrawal, recall, or market prohibition where no other effective means eliminates the risk, and notify the Commission. The MSR uses the information and communication system in Article 34 for market-surveillance data, including measures, test reports, corrective action, injury reports, objections, and customs-related entries. Safety Gate is the EU rapid alert system for dangerous non-food products and is relevant when dangerous products and measures need rapid circulation among national authorities.
