Last updated: August 2026 dataCopper alloy wire not elsewhere specified — a residual category that captures alloys such as copper-beryllium, copper-chromium, and other engineered compositions used in spring contacts, welding electrodes, and high-strength electrical connectors. The US schedule distinguishes coated or plated wire (7408291000) from uncoated wire (7408295000), and goods from several leading suppliers, including South Korea and Vietnam, may be subject to Section 301 tariff considerations depending on origin and product specifics. Classifying correctly as NESOI requires ruling out brass, bronze, cupro-nickel, and nickel-silver before applying this heading.

Heading 740829 is a true residual: it applies only after ruling out copper-zinc (brass, 740821), copper-nickel or nickel-silver (740822), and refined copper (740811). Obtain the alloy composition certificate from the mill and verify the principal alloying element is neither zinc nor nickel in the proportions that define those named alloys.
Vietnam is among the leading suppliers under this heading and is not a US free-trade-agreement partner, so goods do not benefit from preferential duty treatment. Depending on the specific 10-digit line and product, Section 301 measures may also apply. Importers should consult a licensed customs broker to confirm the current duty treatment for their specific alloy and origin.
