Supplier Qualification Questions for Laboratories

A supplier questionnaire is useful when the answers can be inspected. Ask which records support a statement, what products or activities it covers and who is responsible. A “yes” without scope can hide the uncertainty your laboratory needs to resolve.

Business and responsibility

Ask for the contracting identity and a practical contact route. Establish who handles specification questions, quality concerns and document corrections. Ask which activities the supplier performs itself and which involve another organisation.

A trading address does not establish manufacturing location, and a supplier-issued certificate does not automatically establish independent testing. Manufacturing and testing roles explains that distinction.

Questions that produce usable evidence

AreaQuestionEvidence to request where relevant
IdentityHow is the offered form or variant defined?Applicable specification and revision
TestingWhich attributes were examined for this lot?Report, method, results and limitations
SamplingHow is the tested sample connected to the supplied lot?Sample and lot relationship
ReleaseWhat criteria and decision apply to the lot?Recorded disposition and relevant criteria
TraceabilityCan an order be connected to its containers and lots?Explanation of the retrievable record relationship
StorageWhich instructions govern this presentation?Material-specific conditions and basis
ConcernsHow is an affected lot identified and a correction communicated?Applicable process and responsible contact

These questions do not assume that every supplier has a pharmaceutical quality system or that every listed document must exist for every material. Your laboratory should decide which evidence is necessary for the proposed work.

Follow up on ambiguous answers

If the answer is “all batches tested”, ask which tests, on which samples, and how the reports can be matched to the lot offered. If it is “temperature controlled”, ask for the relevant conditions and arrangement. If records are confidential, ask what verifiable information can be provided through an appropriate route.

Do not turn a confidentiality statement into a positive verification result. Record the scope of what you actually reviewed.

Apply the questionnaire to a purchase

Use the procurement checklist to connect the answers with the material requirement and order. The testing-methods page helps interpret analytical terms, and laboratory verification addresses testing-party evidence.

For Knockout Labs, send the requirement through supplier qualification. This guide asks questions on the buyer’s behalf; it does not answer them for the supplier or certify the outcome.

Use the pre-order document guide to identify the particular record needed for each unanswered question.
