U.S. exports of Refined Copper Wire Bars, Unwrought (HS 740312) totaled $205K in August 2026, exported to 3 countries.
Last updated: August 2026 dataWire bars are a cast, unwrought refined copper form historically used as the direct feedstock for wire-drawing operations before continuous casting largely displaced them in high-volume rod production. Switzerland, Japan, and China are the recorded US import sources for this heading, a supply profile that reflects specialty or legacy demand rather than bulk commodity flows. Classified under the single line 7403120000, wire bars must be distinguished from billets (7403130000) — which are cylindrical and fed to extrusion presses — and from cathodes, which are electrodeposited rather than cast.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Wire bars are typically rectangular or trapezoidal in cross-section with tapered ends, designed for rolling or drawing into wire rod. Billets (heading 740313) are cylindrical or round in cross-section and are intended for extrusion. CBP may request dimensional specifications or a producer's certificate to confirm the form when the shape is ambiguous.
Yes — continuous casting of copper rod has largely replaced wire bars in high-volume electrical wire production because it is more efficient. Wire bars today are primarily used in specialty applications or by smaller fabricators without continuous-cast equipment, which explains why US import volumes under this heading are modest and sourced from a small number of countries.
