Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-tin base alloys regardless of tin content
Any bronze composition (tin predominant per note b) goes to 7408.29, even for fine wires.
If further processed into refined copper tubes
Drawn/seamed copper tubes from same refined stock classify under 7410, not wire.
If insulated and rated >80V for data transmission
Electrically insulated copper strand for data cables moves to Chapter 85 ignition wiring.

Import Tips & Compliance
• Certify oxygen content <10ppm with manufacturer specs to qualify as refined copper
• Declare drawbench process; continuous-cast rod-derived wire must trace back to refined cathode
