C101 Oxygen-Free Refined Copper Wire Bar
A high-purity wire bar made from refined copper (C101 grade) with minimal oxygen content, designed specifically for drawing into fine electrical wires. It falls under HTS 7403.12.00.00 as it is unwrought refined copper in the form of wire bars, used in wire production for electronics and telecommunications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from copper-zinc base alloys (brasses)
Copper-zinc alloys where zinc predominates over other elements (excluding nickel silvers) are classified under copper alloy wire bars per subheading note (a).
If processed into wire of refined copper
Once drawn into finished wire profiles, it moves from unwrought wire bars to Chapter 74 heading for refined copper wire.
If in the form of cathodes or sections of cathodes
Alternative unwrought forms like cathodes are under 7403.11, differing from the specific wire bar shape required here.

Import Tips & Compliance
• Verify copper purity exceeds 99.99% with mill test certificates to confirm refined status and avoid misclassification as alloy
• Ensure documentation specifies 'wire bar' form and end-use for wire drawing to comply with unwrought definitions
• Check for free trade agreement eligibility like USMCA, as refined copper often qualifies for reduced duties
