Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as copper-zinc alloy unwrought anodes
Unwrought copper-zinc alloys fall under 7403.21 before wire drawing, per chapter definitions.
If drawn to 7-9 mm diameter
Precise thickness determines subheading; 6-9.5 mm refined wire uses 7408.11.25.00.
If rated over 80V and insulated for winding wire
Insulated copper winding wire over 80V shifts to Chapter 85 electrical conductors.

Import Tips & Compliance
• Require UNS C10100 material certification with conductivity testing to confirm refined status
• Measure cross-section at multiple points; ovality beyond tolerances can affect duty bracket
• For defense contracts, ensure ITAR compliance even for commercial wire grades
