More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the maximum cross-sectional dimension exceeds 9.5mm but not 12.7mm
This sibling tariff item covers refined copper wire of a larger dimension, so wires over 9.5mm would be classified here.
If the wire is made of a copper alloy rather than refined copper
Copper alloy wire falls under subheading 7408.19, as the definition of refined copper in Chapter Note 1(a) would not apply.
If the maximum cross-sectional dimension exceeds 12.7mm
This sibling tariff item covers refined copper wire exceeding 12.7mm, which would be classified here instead.

Import Tips & Compliance
• Ensure the wire's cross-sectional dimension is accurately measured and documented, as classification depends on it being over 6mm but not over 9.5mm
• Provide a mill certificate or assay confirming the copper purity (at least 99.85% by weight) to support the refined copper claim
• Verify whether the wire is considered 'unworked'—if it has been further processed, it may fall under a different heading
