Conveyor belt certificates can mean very different things in an international purchase. This guide helps importers and tender buyers distinguish COAs, product test reports, ISO management-system certificates and third-party inspection documents. It explains what each document can verify, how to check standards and traceability, when independent inspection may be required, and how to include documentation requirements in an RFQ. Buyers can also use the practical checklist to compare conveyor belt suppliers on the same technical and commercial basis.
