Prior to order, obtain the latest certificate of analysis, moisture and purity test reports, and any food‑grade certification documents to confirm compliance with your market regulations. Request a batch traceability record that lists the production date and raw material source. Verify that the supplier’s export licence covers the destination country.
Discuss shipping options such as FOB Laizhou port or CIF Shanghai, and ask the supplier to provide an estimated lead‑time for the required quantity.
