Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloyed with elements like phosphorus for welding
Phosphor bronze welding wire (copper-tin alloy) uses the general copper alloy wire heading.
If coated with welding flux or covered electrodes
Flux-coated welding wire or electrodes shift to Chapter 83 for coated metal products.
If processed into bars/profiles rather than wire form
Thicker rectangular forms classify as copper bars, not wire.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Certify as bare wire without flux coating; coated welding wire may classify differently
• Provide end-use statements distinguishing from electrical wire to avoid Chapter 85
• Measure spools accurately; oversized coils risk dimension-based reclassification
