EU Market Surveillance Regulation Article 4 setup workflow

Article 4 requires an EU-established economic operator for products covered by the listed Union harmonisation legislation before those products are placed on the EU market.

Use this workflow to confirm product-law coverage, assign the responsible operator, verify contact details, collect conformity evidence, and prepare marketplace, authority-response, and import-release records.

Overview

Article 4 setup is not a generic compliance review. For each product family and sales route, the team must prove that the product is covered, identify the EU-established operator responsible for Article 4(3) tasks, show that the operator's details appear with the product, and keep evidence ready for market-surveillance or customs checks.

Section 1

1. Confirm that Article 4 covers the product

Start with a product-law coverage table, not with a sales launch checklist. Article 4 applies only to products subject to the legislation listed in Article 4(5) or to another act that expressly points to Article 4. Record the exact product family, model or SKU, intended EU market, applicable Union harmonisation legislation, and whether the offer is targeted at end users in the Union through online or other distance sales.

Match each product line to the relevant listed regime, such as machinery, toys, electrical equipment, radio equipment, EMC, RoHS, ecodesign, pressure equipment, PPE, gas appliances, construction products, pyrotechnics, recreational craft, outdoor noise, measuring instruments, non-automatic weighing instruments, or simple pressure vessels.
Mark products out of scope when the grounding act is not one of the Article 4(5) instruments and no other applicable product rule makes Article 4 relevant.
For online listings and direct-to-consumer imports, record the EU-targeting facts because distance-sale offers targeted at EU end users are treated as making the product available on the market.

2. Assign the responsible EU economic operator

For each covered product, assign exactly who will perform the Article 4(3) tasks before the product is placed on the market. Use the Article 4 role order and keep the evidence that proves the selected role, because the answer changes with the supply chain.

Use the EU manufacturer when the manufacturer is established in the Union, unless a written Article 4 mandate appoints an authorised representative.
Use the importer when the manufacturer is outside the Union and an EU importer places the product on the EU market, unless a written Article 4 mandate appoints an authorised representative.
Use an authorised representative only when the manufacturer has given a written mandate covering the Article 4(3) tasks; keep the signed mandate and any language version needed for authority requests.
Use an EU fulfilment service provider only for products it handles when there is no EU manufacturer, importer, or authorised representative; keep the client/manufacturer arrangements showing access to the declarations, documentation, and contact channels needed to perform Article 4 tasks.

Section 3

3. Verify EU contact details on the product record

Treat contact marking as a release gate. Article 4 requires the responsible operator's name or registered trade name/trademark and contact details, including postal address, to appear on the product, packaging, parcel, or accompanying document. A website can support contact routing but does not supersede the postal address.

Capture label, packaging, parcel, manual, and accompanying-document proofs for each product version and marketplace listing.
Check that the displayed operator matches the role decision: EU manufacturer, importer, authorised representative, or fulfilment service provider.
Store evidence of postal address verification and any email or phone channel used for fast authority contact.
Block release when the named operator is different from the signed mandate, import record, or fulfilment arrangement.

Section 4

4. Build the declaration and technical-documentation evidence pack

The Article 4 operator does not need to recreate the technical file, but must be able to verify that required declarations and technical documentation have been drawn up, keep the declaration or declaration of performance available for the period required by the applicable legislation, and ensure technical documentation can be made available to authorities on request.

Keep the EU declaration of conformity or declaration of performance, where the applicable product rule requires one.
Keep a technical-documentation index showing owner, storage location, applicable product legislation, conformity-assessment route, standards or specifications used, test reports or certificates, and manufacturer contact.
For importers, keep written assurance or equivalent supplier evidence that the manufacturer will provide the EU declaration and technical documentation when needed.
For fulfilment service providers acting under Article 4, require clients or manufacturers to provide declarations, manufacturer contact details, and a process for technical-document retrieval before fulfilment starts.

5. Define the authority-response and corrective-action process

Article 4 setup should leave the operator ready to answer a reasoned market-surveillance request. The response process needs an owner, a documentation retrieval path, a language check, and an escalation route for risk or non-compliance findings.

Assign a response owner who can provide information and documentation necessary to demonstrate conformity in a language easily understood by the requesting authority.
Set an evidence retrieval service level internally, but do not publish unsupported legal deadlines; the legally relevant timing will come from the authority request or the applicable product legislation.
Define the risk trigger: when the operator has reason to believe the product presents a risk, the process must notify market surveillance authorities.
Prepare corrective-action records for actions that bring non-compliance to an end or mitigate risk, including withdrawal, recall, warnings, release conditions, or other measures where required by authorities.

6. Maintain marketplace and import-release evidence

Close Article 4 setup by connecting the product evidence pack to the channels where non-compliance is likely to be checked: marketplace listings, fulfilment flows, importer records, and release-for-free-circulation files. The record should show that the product had a valid Article 4 operator before sale or release, not only after an authority question arrived.

For marketplaces and online shops, keep screenshots or exports showing the product offer, EU targeting facts, responsible operator details, SKU/model mapping, and listing owner.
For direct import or fulfilment flows, keep commercial invoice, shipment, fulfilment-client, importer-of-record, and responsible-operator mapping evidence.
For border holds or release checks, keep the product-group screening file, conformity documents supplied, authority/customs correspondence, sample or inspection records, and the final recommendation or release decision.
Refresh the pack when the manufacturer, importer, authorised representative, fulfilment provider, product model, applicable legislation, declaration, label, packaging, marketplace listing, or import route changes.
