EU Low Voltage Directive Post-market controls

Manufacturers' duties continue after CE marking. They must keep series production in conformity, take account of product-design and standard or technical-specification changes, and, where the equipment's risks make it appropriate, sample-test marketed equipment, investigate complaints, keep any necessary register of complaints, non-conforming equipment and recalls, and keep distributors informed. These controls are risk-based, but the duty to act on known non-compliance is not optional.

Importers have parallel risk-based sample-testing, complaint-investigation, register, and distributor-information duties for equipment they place on the market. Distributors have a narrower but active duty: act with due care, check CE marking, required documents, instructions, safety information, and manufacturer and importer identification before making equipment available, and stop supply when they have reason to believe the equipment does not meet the Annex I safety objectives.

Storage and transport remain part of control. Importers and distributors must ensure that conditions while equipment is under their responsibility do not jeopardise compliance with the Annex I safety objectives. A post-market procedure should therefore connect complaints and incidents to warehouse holds, shipment stops, distributor notices, product identification, and the technical documentation for the affected version.

When a manufacturer or importer considers, or has reason to believe, that equipment it placed on the market is not in conformity with the LVD, it must immediately take the corrective measures needed to bring the equipment into conformity, withdraw it, or recall it, as appropriate. Correction may address units before further supply; withdrawal prevents affected equipment in the supply chain from being made available; recall seeks the return of equipment already made available to an end user.

Distributors must make sure corrective measures are taken for equipment they made available. If the equipment presents a risk, manufacturers, importers, and distributors must inform competent national authorities in the Member States where the equipment was made available and give details of the non-compliance and corrective measures taken.

Post-market controls need both documentation and safety response paths. Manufacturers must keep the technical documentation and EU declaration of conformity for 10 years after equipment is placed on the market. Importers must keep a copy of the EU declaration for the same period and ensure the technical documentation can be made available to market surveillance authorities on request.

The technical documentation should support an authority's conformity review for the affected product version. Annex III calls for a general equipment description, design and manufacturing drawings, explanations needed to understand those drawings and operation, an adequate risk analysis and assessment, applied harmonised standards or alternative solutions, design calculations and examinations, and test reports.

LVD economic operators must cooperate with competent national authorities after reasoned requests. Manufacturers, importers, and distributors must provide information and documentation needed to demonstrate conformity, and cooperate on action taken to eliminate risks posed by equipment they placed or made available on the market.

Regulation (EU) 2019/1020 adds the horizontal market-surveillance framework. For products covered by its Article 4, including LVD equipment, there must be an economic operator established in the Union responsible for specified document-verification, authority-response, risk-notification, and cooperation tasks. That operator may be an EU manufacturer, an importer where the manufacturer is outside the Union, a properly mandated authorised representative, or, if none of those is established in the Union, a fulfilment service provider for products it handles.

Market surveillance authorities follow up complaints or reports, verify corrective action, and may require proportionate measures. Those measures can include correction, a stop on supply, withdrawal, recall, destruction, warnings, or alerts to affected end users. For a serious risk, authorities must ensure withdrawal or recall when no other effective means can eliminate the risk, or prohibit the product from being made available.

LVD Article 22 separately addresses formal non-compliance, including CE-marking defects, a missing or incorrect EU declaration, unavailable or incomplete technical documentation, and missing Article 6 or 8 information. Formal non-compliance is not proof that the equipment is safe: it can coexist with a product risk and can trigger further investigation. If it persists, the Member State can restrict or prohibit supply or ensure recall or withdrawal.
