CE marking isn’t optional — and marketplaces that treat it like a checkbox can get caught holding the bill.
EU law now spells out when a platform steps into importer or distributor duties.
That matters: customs can block shipments, market surveillance can force removals, and platforms risk fines or being treated as the legal importer.
This post explains what changed, why it matters for marketplaces selling in the EU, and the practical next steps: verify Declarations of Conformity, demand technical files, and confirm an EU importer or Responsible Person before listings go live.
Practical Compliance Duties for Marketplaces and Sellers
CE marking isn’t optional. It’s a legal requirement. Both marketplaces and sellers need to know where their duties begin and end. Sellers put products on the market, so they’re responsible for making sure those products meet EU conformity rules, carry the CE mark when needed, and come with the right documentation. Marketplaces act as intermediaries, but that doesn’t give them a free pass. Under EU law, they’ve got specific duties to verify, cooperate, and act when unsafe or non-compliant products show up on their platform.
Sellers (whether they’re manufacturers, importers, or distributors) are responsible for ensuring products are CE-marked, tested to the correct standards, and backed by a Declaration of Conformity before listing. If you’re sourcing goods from outside the EU, you either need to act as the importer or designate one. The importer’s name and contact details must appear on the product, packaging, or documentation. Sellers must also maintain technical files, keep test reports, and provide user instructions in the language of the country where the product will be sold. If the product changes (different materials, new design, altered function), the testing and documentation need updating too.
Marketplaces aren’t usually the manufacturer or importer. But they still have obligations. Under the Market Surveillance Regulation (EU) 2019/1020, marketplaces must:
- Verify seller identity and contact details before allowing listings.
- Request and check Declarations of Conformity and supporting test reports for high-risk products.
- Maintain traceability records, including product identifiers, batch numbers, and supplier information.
- Remove or disable access to listings when notified by authorities or when a product gets flagged as unsafe.
- Cooperate with market surveillance authorities by providing records, supplier details, and transaction data on request.
- Implement processes to monitor compliance and respond quickly to safety alerts or RAPEX notifications.
When a marketplace takes ownership of goods, presents itself as the seller, or directly imports products, it might become an economic operator (either an importer or a distributor) and inherit the full compliance obligations that come with that role.
Overview of CE Marking and Conformity Assessment
CE marking shows that a product meets the essential health, safety, and environmental requirements set out in applicable EU directives and regulations. It’s not a quality label. It’s a legal declaration that the product complies with harmonised legislation and can be placed on the EU market. CE marking applies to 23 product categories, including electrical equipment, toys, personal protective equipment, machinery, and medical devices. Products outside these categories don’t carry CE marking, even if they must meet other EU safety rules. Cosmetics, for example, require a Product Information File but aren’t CE-marked.
Conformity assessment is how manufacturers demonstrate compliance. For some products, the manufacturer can self-certify by testing the product, preparing the technical file, and issuing a Declaration of Conformity. For higher-risk products (certain medical devices, pressure equipment, some machinery), a notified body must get involved. A notified body is an independent third-party organization designated by an EU member state to assess whether a product meets the requirements of a specific directive. When a notified body is involved, its four-digit identification number must appear next to the CE mark on the product.
Legal Responsibilities of Online Marketplaces
Marketplaces are intermediaries, but EU law treats them as active participants in product safety. Under the Market Surveillance Regulation, marketplaces must conduct due diligence on sellers, verify product compliance for high-risk categories, and respond immediately to product safety notices. The Digital Services Act, which applies from February 2024, adds further transparency and reporting obligations, requiring marketplaces to act quickly on illegal content (including listings for unsafe or non-compliant products).
Marketplaces must maintain systems to monitor listings, respond to complaints, and cooperate with national market surveillance authorities. When an authority issues a product safety alert or requests information, the marketplace must provide seller details, transaction records, and product identifiers. If a product turns out to be non-compliant or dangerous, the marketplace must remove or disable the listing, notify affected buyers where possible, and document the actions taken. Refusal to cooperate or repeated failure to remove unsafe products can trigger enforcement action against the marketplace itself.
Marketplaces can’t simply rely on seller declarations. For high-risk products (electronics, toys, PPE, pressure equipment), marketplaces should request copies of the Declaration of Conformity, test reports, and technical file summaries before approving the listing. Spot checks, random product sampling, and independent lab testing are recommended practices for categories with high non-compliance rates. Clear contractual clauses requiring sellers to provide conformity evidence and indemnify the marketplace for compliance failures help manage risk.
Import Rules and Compliance Obligations for Non‑EU Sellers
When a product is manufactured outside the EU and sold into the EU market, someone must act as the importer. The importer is the economic operator who first places the product on the EU market and is responsible for ensuring it complies with EU law. If a non-EU seller ships directly to EU buyers without designating an EU-based importer, the marketplace may be treated as the importer by default, particularly if it takes ownership, handles customs clearance, or presents itself as the seller.
Before goods clear EU customs, the importer must confirm that the product is CE-marked (where applicable), that a Declaration of Conformity exists, and that the technical file is available for inspection. Customs authorities may request documentation at the border. Products missing a CE mark, lacking a Declaration of Conformity, or flagged as unsafe can be refused entry, held for inspection, or destroyed. The importer bears the cost of storage, inspection fees, and return shipments when compliance issues are discovered at customs.
The importer’s name and contact details must appear on the product, packaging, or user instructions. If the product carries the manufacturer’s CE mark but was privately labeled or custom-designed, the seller may be treated as the manufacturer rather than the importer, triggering the full set of manufacturer obligations, including testing, technical file creation, and Declaration of Conformity issuance.
Required documentation for import includes:
- Commercial invoice with accurate HS codes and product descriptions.
- Declaration of Conformity listing applicable directives, standards, and notified body details (if involved).
- Test reports from accredited labs demonstrating compliance with harmonised standards.
- Proof of product traceability: batch numbers, serial numbers, or other identifiers matching the certificate and technical file.
EU Responsible Person Requirements for Third‑Country Manufacturers
For certain product categories (most notably medical devices and, in some cases, toys), a Responsible Person based in the EU must be designated by the manufacturer. The Responsible Person acts as the manufacturer’s point of contact for EU authorities, ensuring that technical documentation is available, responding to compliance inquiries, and cooperating during investigations or recalls. The Responsible Person doesn’t replace the manufacturer’s obligations but serves as the EU-based compliance liaison.
The Responsible Person’s name and address must appear on the product label or packaging, and they must hold a complete copy of the technical file, Declaration of Conformity, and supporting test reports. If an authority requests documentation, the Responsible Person must provide it within the timeframe specified by the directive (often immediately or within a few working days). Marketplaces and sellers should verify that a Responsible Person has been designated where required and that contact details are included on the product before listing.
Technical Documentation and Declaration of Conformity
The technical file is the core compliance document. It must include a product description, design drawings, bill of materials, wiring diagrams, risk assessment, test reports, user instructions, and labeling details. For electrical products, testing typically covers electrical safety (Low Voltage Directive), electromagnetic compatibility (EMC Directive), and restriction of hazardous substances (RoHS). For toys, testing includes mechanical and physical properties, flammability, chemical migration, and labeling. For PPE, the technical file must document the conformity assessment module used and the notified body’s certificate.
The Declaration of Conformity is a signed statement by the manufacturer or importer confirming that the product meets all applicable directives and harmonised standards. It must list the product name, model or type, batch or serial number, applicable directives, harmonised standards referenced, the notified body identification number (if involved), and the name and signature of the person authorized to issue the declaration. The Declaration of Conformity must accompany the product or be made available on request.
Marketplaces should request a copy of the Declaration of Conformity before approving high-risk product listings. Sellers must provide it. A missing or incomplete Declaration of Conformity is a red flag. If the seller can’t produce the document, the product shouldn’t be listed. Similarly, test reports must match the product being sold. Reports for a similar-looking product or an older version don’t satisfy the requirement.
Market Surveillance, Product Recalls, and Enforcement Actions
Market surveillance authorities in each EU member state monitor the market for unsafe or non-compliant products. They conduct physical inspections, review online listings, purchase products for testing, and investigate complaints. When a product is found to be non-compliant, the authority issues a corrective action order requiring the seller, importer, or marketplace to withdraw the product, recall it from buyers, or modify the listing.
RAPEX (the Rapid Alert System for Non-Food Products) publishes weekly alerts about dangerous products found in the EU. Alerts include product photos, brand names, model numbers, and the risk identified. Marketplaces must monitor RAPEX alerts and remove matching listings immediately. Failure to act on a RAPEX alert can result in enforcement action against the marketplace.
When an authority opens an investigation, the marketplace must provide seller contact details, transaction records, product identifiers, and copies of any compliance documentation requested. Sellers must cooperate by providing the technical file, test reports, and Declaration of Conformity. Refusal to cooperate, missing documentation, or evidence of deliberate non-compliance escalates enforcement and increases penalties. Marketplaces that implement fast-removal workflows, maintain clear traceability records, and cooperate fully with authorities reduce their own exposure during enforcement actions.
Penalties and Consequences for Non‑Compliance
Fines for CE marking violations vary by member state but can reach €100,000 or more for serious breaches. Products may be seized at customs, held pending corrective action, or destroyed. Marketplaces face listing bans, mandatory recalls, and reputational damage. In severe cases (particularly when a non-compliant product causes injury or death), criminal liability may apply to the manufacturer, importer, or responsible economic operator.
Beyond fines, non-compliance triggers operational costs: customs storage fees, return shipping, legal fees, and the expense of recalling or withdrawing products already sold. Marketplaces that fail to remove non-compliant listings after being notified may be held jointly liable for damages. Sellers who can’t produce a Declaration of Conformity or technical file when requested face immediate sales bans and potential cross-border enforcement across all EU member states.
Final Words
In the action: marketplaces need to verify CE marks, request Declarations of Conformity, maintain traceability, and act quickly on unsafe notices. Sellers must test products, keep technical files, and ensure proper labeling before import.
This matters because customs, market surveillance, and platform liability can stop listings, trigger recalls, or levy fines. Clear roles cut risk and speed market access.
