Supplier Qualification
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
Supplier qualification is the risk-based process of evaluating and approving external suppliers of materials and services — assessing their capability, quality system, and reliability before use and monitoring their ongoing performance thereafter. It typically combines documentation review, questionnaires, on-site or remote audits proportionate to risk, and confirmation of the supplier's controls, formalized in a quality agreement that defines each party's responsibilities. The manufacturer retains responsibility for the quality of purchased materials regardless of the supplier's status.
Qualification depth follows risk: a critical starting material or a sterile-service provider warrants audit and a detailed quality agreement, while a low-risk commodity may be qualified on documentation. The principle is that you cannot delegate away accountability — approving a supplier does not transfer the responsibility for the incoming material's quality.
Ongoing performance monitoring (rejects, complaints, change notifications, requalification intervals) is part of qualification, not a separate afterthought — a supplier can drift out of a qualified state.
