Arrange the evidence before agreeing to buy. A clear inspection plan connects the supplied material to the specification and to the documents used to support it.
Identify the shipment
Ask for the supplier’s lot reference and any applicable heat, coil or bundle identifiers. Record how those identifiers appear on labels and documents. If material has been cut or repacked, ask how the original identification has been retained.
Define the checks
Agree the required documents, dimensional checks, surface checks and any testing appropriate to the application. Name who will inspect, where and when it will happen, and what happens if access is unavailable.
Read documents critically
Match the grade, dimensions, identifiers and test results to the order. Check the issuer through an independent channel if authenticity is uncertain. Do not treat a photograph of a certificate as proof of an unrelated lot.
Put acceptance in writing
Record tolerances, permitted deviations, inspection timing, rejection or claims procedure and responsibility for costs. Keep the final specification revision with the quotation and contract.
Use the private deal room for commercial questions. Avoid putting personal identity or banking documents in public listings. See material condition and quotation comparison.
