Procurement notes / Guide 01

Before you approve
a research supplier.

A practical documentation checklist for professional purchasing teams. Completing it records your review; it does not certify a supplier or a product.

The direct answer

Before approving a research supplier, establish who is supplying the material, which batch is covered, what was actually tested and who issued the supporting evidence.

01Identify the trading entityAsk for the exact legal name, registration details and an accountable contact. A brand name alone is not enough to identify a supplier.02Match the batch identifiersCompare the supplier record, label and certificate. Ask for an explanation of any mismatch before relying on the record.03Inspect the complete reportLook beyond a headline figure. Read the report reference, date, methods, results and limitations. Request the full source document.04Check the laboratory’s identityConfirm who issued the report. If accreditation is claimed, check both the listing and the relevant scope with the accreditation body.05Separate findings from assumptionsA test result is evidence about the tested sample under stated conditions. It does not automatically establish every property of every supplied unit.06Record your decisionKeep the source documents and the reasons for your purchasing decision. Unanswered questions should remain visible in the review.

What a checklist cannot prove

A completed checklist is not laboratory testing, accreditation, legal approval or an authenticity determination. Where evidence is missing, ask the accountable supplier or a qualified specialist to resolve the gap.

This checklist is Reta Dynamic’s proposed procurement review framework, not a recognised certification standard. For a UK laboratory claiming accreditation, check its listing and scope using the UKAS organisation directory.
