Review evidence, not only claims
Ask for a coherent document set and verify that names, codes, methods and limits agree. Confirm the legal company name, business contact, manufacturing or supply role, quality responsibilities and how complaints or specification changes are handled.
Use a staged qualification process
Begin with document review, then evaluate a traceable sample, clarify commercial terms and complete any required audit or third-party testing. Record unresolved issues before approving the supplier or material.
