What to establish

Ask whether the contracting party is the manufacturer, exporter, distributor or coordinator. Map manufacturing, testing, storage and export handoffs. Request the manufacturer’s relevant quality documentation and a lot-linked specification and COA rather than relying on broad country-of-origin claims.

What to verify

For a pre-purchase sample, record the sender, seal, sample ID and method plan. Independent testing can reduce an evidence gap but does not prove that a later shipped lot is identical. Agree in advance on discrepancy handling and change notification.

Decision and next step

Confirm import and customs requirements with the destination’s qualified importer. FDA notes that US API import is subject to applicable requirements; this guide does not promise admissibility, specific lead times or a universal regulatory route.

Practical request

Use the points above to request a defined product, sample or lot record. Ask the document issuer to explain any discrepancy; do not infer regulatory suitability from a catalog listing.
