Import Tips

Obtain ITP (Inspection Test Plan) approval from importer/buyer before shipment; critical for customs clearance

Declare exact grade (P-110) and premium class on commercial invoice; incorrect specification leads to reclassification

Budget for anti-dumping duties if sourced from certain countries; check Commerce scope rulings for stainless casing
