Review supplier evidence by linking every document to one claim, one product and one responsible legal entity. Confirm the document issuer, tested or declared model, method, date and result. Then compare those details with the quotation and physical sample. Unlinked certificates, generic catalogs and factory photos may provide context, but they do not prove the quoted product specification.
1. Verify the contracting entity
Compare the company name on the quotation, business registration, invoice and bank account. If manufacturing is subcontracted, record the factory role and who accepts responsibility for the order.
2. Build a claim-to-evidence table
Create one row for every material, dimension, performance or compliance claim. Record whether the support is a supplier declaration, report, measurement, sample observation or still missing.
- Exact product or model linked to the document
- Document issuer and issue date
- Test or inspection method and reported result
- Consistency with quotation, label and sample
- Gaps that must remain excluded from marketing copy
3. Check the sample against the document set
Measure visible and dimensional fields and photograph the reviewed sample. Keep an approved control sample or an equivalent signed record before defining pre-shipment inspection criteria.
4. Preserve uncertainty
When evidence is incomplete, state that the field is supplier-declared or pending verification. Do not turn a target specification or unrelated report into a verified product claim.
Method and claim boundary
This guide describes SPECVANTA's RFQ and quality-control method. Product specification, price, MOQ, sample terms, certification scope and delivery time for an order are confirmed only in the applicable SPECVANTA quotation and approved documents.
Review the quality and evidence processCommon questions
Do factory photos prove manufacturing capability?
No. Photos can provide context, but they do not establish ownership, current production control or capability for the exact quoted product without supporting identity and production evidence.
Can one test report cover every product in a range?
Only when the report scope and product identification support that conclusion. Otherwise, record which specific model or construction was tested.
What should happen when a claim cannot be verified?
Keep it marked as unverified, request better evidence or remove the claim from the approved specification and marketing content.
