Before placing an order, request the mill test report, material certification and dimensional inspection data to verify that the pipe grade and size match your project specifications. Confirm that the supplier can provide the required certificates, such as ISO or MTC, and that the testing methods align with your quality assurance plan.
Discuss logistics early by asking the supplier to specify the preferred incoterm, such as FOB Shanghai or CIF Ningbo, and to outline the expected lead time for production and shipping. Clarify payment terms, including any advance deposit and documentary letters of credit, to ensure smooth financial processing.
Arrange for third‑party inspection either at the factory or prior to loading to guarantee compliance with the agreed standards. Request the inspection certificate and any additional documentation, such as a packing list and certificate of origin, to facilitate customs clearance and downstream quality checks.
