Before ordering, confirm that the bolts are supplied in carbon steel with a hot‑dip galvanised finish and that they meet the ASTM A325 or A490 standards required for your project. Request the mill test report and verify the tensile strength values for the chosen grade. It is also prudent to check the packaging configuration to ensure it matches your handling and storage procedures.
Logistics from Handan typically involve trucking to a nearby port such as Tianjin or Shanghai, where containers are loaded for sea freight. Discuss the preferred Incoterm - FOB, CIF or DAP - and clarify payment terms, including any letter of credit or advance payment requirements, before finalising the contract. Freight costs and transit times will vary by destination, so obtain a shipping quote from a freight forwarder.
Upon arrival, perform a visual inspection of the galvanised coating and verify dimensions against the order specifications. Arrange for a third‑party inspection if required, and request documentation covering tensile strength, corrosion resistance and compliance with ASTM standards. Ensure the supplier provides a certificate of conformity and any relevant test reports alongside the shipment.
