Product classification
HS code for Copper wire: 7408.19
Copper, wire, of refined copper, of which the maximum cross-sectional dimension is 6mm or less.
Classification of copper wire under HS 7408.19
Copper wire is classified under HS code 7408.19, provided it consists of refined copper and has a maximum cross-sectional dimension of 6 mm or less. This classification follows the legal notes of Chapter 74, which defines wire as rolled, extruded, or drawn products, in coils, which have a uniform solid cross-section along their whole length in the shape of circles, ovals, rectangles, squares, equilateral triangles, or regular convex polygons. The classification under 7408.19 is specific to refined copper, as defined in Note 1(a) to Chapter 74, which requires a metal content of at least 99.85% copper by weight, or a minimum of 97.5% copper provided no other single element exceeds specified limits. The 6 mm threshold is a critical boundary in the Harmonized System; products exceeding this dimension are generally classified as bars or rods under heading 7407. The manufacturing process typically involves drawing a wire rod through a series of dies to reduce its diameter, a process that distinguishes it from unwrought forms of copper found in heading 7403.

Codes often confused with 7408.19
Common mistake. The most common misclassification occurs between 7408.19 and 7408.11. Code 7408.11 is reserved for refined copper wire where the maximum cross-sectional dimension exceeds 6 mm. Importers often fail to measure the diameter accurately, leading to incorrect filings. Another frequent error is classifying insulated copper wire under 7408; however, once any form of electrical insulation is applied, the product must be moved to Chapter 85, specifically heading 8544. Furthermore, copper alloy wire (such as brass or bronze) should not be classified here but under 7408.21 or 7408.29, depending on the alloy composition.
Top exporters and importers of HS 740819 (the code used for copper wire), 2025
In 2025, the largest exporter of HS 740819 (the code used for copper wire) in UN Comtrade data was China, with 20% of world exports; the largest importer in UN Comtrade data was China, with 8.0% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
