Phosphorized Refined Copper Welding Wire from China
12.7 mm diameter phosphorized refined copper wire used for gas-shielded welding applications in marine and plumbing industries. Falls under HTS 7408.11.30.00 as it's refined copper (phosphorus deoxidized per ASTM B280) with cross-section over 9.5 mm. The trace phosphorus (<0.015%) doesn't qualify as alloying.

Import Tips
• Include ASTM B280 certification specifying phosphorized refined copper to distinguish from alloys
• Document intended welding end-use but classify based on form, not application, to avoid 83xx tool steel confusion
• Check for anti-dumping duties if sourced from certain Asian producers; verify Commerce scope rulings
