Last updated: August 2026 dataFine and medium refined copper wire—at or below 6 mm in maximum cross-sectional dimension—is one of the most widely traded copper mill products, serving winding wire, automotive wiring harnesses, electronics, and telecommunications cable manufacturing. The US schedule provides three lines: wire 3 mm or less (7408190030), other refined copper wire (7408190060), and a legacy catch-all (7408190000). Canada leads US imports, with China and Thailand also major sources; China's presence makes Section 301 tariff exposure a live compliance issue that importers must monitor for applicable exclusions. The fine-wire segment is particularly sensitive to copper cathode price volatility, as the conversion premium over cathode is relatively thin.

Wire with a maximum cross-sectional dimension of 3 mm or less is specifically provided for at 7408190030, while wire above 3 mm but not over 6 mm falls under 7408190060. Importers should obtain dimensional specifications from the manufacturer and confirm them against the invoice description. For drawn wire sold in mixed coil sizes, each size may need to be classified separately if the dimensions straddle the threshold.
Refined copper wire from China may be subject to Section 301 tariffs under the applicable list. The scope, rate, and any product-specific exclusions can change, and exclusions that were previously granted may have expired. Importers sourcing from China should verify the current Section 301 status of their specific product with a licensed customs broker before each shipment to avoid unexpected duty liability.
