Phosphorized Refined Copper Welding Wire from Japan
12.7 mm diameter phosphorized refined copper wire used for gas-shielded welding applications in marine and plumbing industries. The phosphorus deoxidization qualifies it as refined copper, and the diameter is exactly at the upper limit of the 9.5 mm to 12.7 mm range, so it is classified under tariff item 7408.11.20.

Import Tips
• Confirm the phosphorus content does not make the wire a copper alloy—phosphorus is not listed in the refined copper table, but ensure total other elements do not exceed 2.5% by weight
• Provide a mill certificate showing the exact composition
• Since the diameter is at the upper limit, measure precisely to avoid misclassification
