Ask about legal identity and supply role
Confirm the legal company name, whether the company is a manufacturer, distributor or professional supply partner, who issues product documents and who coordinates inspection and technical communication.
Verify product and document capability
Ask for exact model, applicable standard, model-specific datasheet, certificate or test report, construction details, traceability, inspection process and packaging evidence.
Check delivery accountability
Confirm stock against the actual model and quantity, MOQ, lead time, shipping documents, complaint handling, non-conformity process and technical contact.
Create a document-based scorecard
Compare product fit, document completeness, model traceability, project communication, delivery coordination and commercial terms only after technical equivalence is established.
