U.S. exports of Refined Copper Wire (SITC 68241) totaled $94.0M in August 2026.
Importers of Refined Copper Wire paid $6.9M in duties in August 2026, an average duty rate of 22.01% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataRefined copper wire — drawn from high-conductivity cathode copper — is the foundational conductor in power transmission, building wiring, motor windings, and telecommunications infrastructure, making it one of the most widely traded copper semi-fabricates globally. The electrical grade (typically ETP or OF copper with conductivity at or above 100% IACS) is the critical specification that distinguishes this product from lower-purity or alloyed wire. Section 232 measures on copper products can affect landed cost, and importers should track any country-specific exclusions that may apply to their supply chain. Wire diameter and whether the product is bare or coated further influence HTS classification at the 10-digit level.

Electrolytic tough pitch (ETP) copper contains a small amount of oxygen and is the standard electrical-grade wire; oxygen-free (OF) copper is processed to eliminate oxygen for applications requiring higher ductility or hydrogen embrittlement resistance. Both are classified as refined copper wire under this heading, but the grade should be documented on the commercial invoice and mill certificate because it affects end-use suitability and may be relevant to buyer specifications or government procurement requirements.
At the 10-digit HTS level, refined copper wire is typically subdivided by cross-sectional diameter (e.g., over a specified millimeter threshold). Importers should measure the maximum cross-sectional dimension of the wire as drawn and confirm the applicable tariff line with a licensed customs broker, as misclassification by size can result in duty underpayments or overpayments.
