Import Tips

• Verify ASTM A325 certification and provide mill test reports (MTRs) to confirm material grade and mechanical properties for customs compliance

• Ensure bolts, nuts, and washers are entered together in the same shipment to qualify under this subheading; separate shipments may reclassify

• Check for anti-dumping duties on certain steel bolts from specific countries and label with country of origin clearly
