Once your product is on the market, post-market surveillance (PMS) is an ongoing legal obligation. Most hardware companies underinvest in PMS — until a market surveillance authority comes asking for their monitoring records.

This includes customer support tickets, retailer returns with failure notes, and online reviews mentioning safety issues. ### Market surveillance monitoring Track Safety Gate (RAPEX) alerts for similar products in your category. If competitors' products are being recalled for safety issues relevant to your design, assess whether the same risk exists in your product. ### Post-market clinical or field data review For regulated categories, review field data periodically to confirm the risk assessment remains valid. If new failure modes emerge that weren't anticipated in the original assessment, update the technical file. ### Standard and regulatory change tracking Harmonised standards get updated and OJ citations get amended. Monitor the standards that support your CE marking and assess whether updates require product or documentation changes. ### Corrective and preventive action (CAPA) When PMS identifies issues, document the root cause, corrective action taken, and verification that the action was effective. CAPA records are a key part of the technical file update. ## When you must notify authorities * An accident or serious near-miss involving the product — national competent authority must be notified * Identification of a serious risk that was not anticipated in the original conformity assessment * Discovery that the product does not conform to applicable CE requirements after being placed on the market * Market surveillance authority request for product information, documentation, or samples * Identification of a need for a product recall or withdrawal from the market ## Frequently asked questions ### Is post-market surveillance a legal requirement for CE-marked products? Yes. Multiple CE directives and GPSR require manufacturers to monitor their products after placing them on the market. The EU Blue Guide explicitly states that CE marking conformity assessment covers the state of the product at the time of placing on the market — manufacturers remain responsible for identifying and addressing non-conformities discovered after market placement. ### How often should I review my PMS data? There is no fixed frequency prescribed by most CE directives — but the review cycle should be appropriate to the risk level of the product. High-risk products (medical devices, machinery) typically require annual or more frequent PMS reports. Consumer electronics should have at minimum an annual review, with triggered reviews whenever complaint rates spike or a significant field incident occurs. ### Does a product recall require CE re-marking? If the recall involves a design change that affects conformity with the applicable directives, the technical file and EU DoC must be updated and a new conformity assessment may be needed. If the recall is due to a manufacturing defect (not a design issue), the conformity assessment basis may not change, but the PMS record and corrective action documentation must be updated. ### Who is responsible for PMS — manufacturer or importer? The manufacturer holds primary PMS responsibility. However, importers and distributors have obligations under most CE directives and under GPSR to report safety information back to the manufacturer and to cooperate in any corrective action. Importers must also monitor for complaints from the EU market and ensure they reach the manufacturer. **Disclaimer:** Educational resource only. Not legal advice.
