Judge a document by what it proves, who issued it, which product and site it covers, and whether it's still valid for the intended market. A file named “certificate” is not automatically evidence for every commercial or regulatory question.
Layer 1: identity evidence
Confirm the legal manufacturer, manufacturing site, product name, model, intended use and country of origin. Names and model numbers should remain consistent across quotations, technical files, labels and shipment documents.
Layer 2: technical and quality evidence
- Product specification, drawings and instructions
- Material declarations and relevant test reports
- Inspection records and batch traceability
- Quality-system documents relevant to the quoted site
- Sterilisation or shelf-life evidence where applicable
Layer 3: destination-market evidence
Required evidence depends on the product classification, claims and destination — identify applicable registration, conformity, labelling and importer obligations before shipment, and get jurisdiction-specific advice when you need it.
Layer 4: transaction and shipment documents
The final transaction may require a commercial invoice, packing list, transport document, origin evidence and other agreed records. Details should reconcile with the purchase order, packing configuration and product identity.
This guide provides general commercial education. Product-specific technical, legal and regulatory requirements should be confirmed for the selected product and destination market.
