Counterfeit Part Prevention

Counterfeit part prevention is the set of procurement, quality, traceability, and handling controls used to reduce the risk that counterfeit, suspect, or unauthorized parts enter manufacturing, maintenance, or delivered product.

In manufacturing and regulated supply chains, the term commonly applies to purchased components, electronic parts, raw materials, fasteners, tooling-related items, and replacement parts where authenticity and provenance matter. Controls may include buying from approved or authorized sources, supplier evaluation, purchase order flowdown, certificate and lot traceability, receiving inspection, test or verification activities, segregation of suspect parts, and documented disposition.

Counterfeit part prevention is not the same as general incoming inspection. Incoming inspection may check conformance to specifications, while counterfeit part prevention focuses on authenticity, source legitimacy, traceable records, and response to suspected misrepresentation. It also does not guarantee that counterfeit parts cannot occur; it describes a risk-control process used to identify, prevent, and manage that risk.

The term is especially common in aerospace, defense, electronics, and other quality-sensitive sectors. In AS9100-related contexts, counterfeit part prevention is one of the added supply chain and product integrity controls beyond a general ISO 9001 quality management system.
