Product classification
HS code for Refined copper wire: 7408.19
Copper, wire, of refined copper, of which the maximum cross-sectional dimension is 6mm or less.
Classification of refined copper wire under HS 7408.19
Refined copper wire is classified under HS code 7408.19 based on the definitions provided in the Legal Notes to Chapter 74. Heading 74.08 covers copper wire, which is defined as rolled, extruded, or drawn products, in coils, which have a uniform solid cross-section along their whole length. The cross-section can be in the shape of circles, ovals, rectangles, squares, equilateral triangles, or regular convex polygons. A crucial distinction for this heading is that the term 'wire' only applies to products with a maximum cross-sectional dimension not exceeding 6 mm. Subheading 7408.19 is specifically for wire made of refined copper. Refined copper must meet the purity standards set out in Note 1(a) to Chapter 74, ensuring the copper content is at least 99.85% or meets specific elemental limits. The classification process involves verifying that the product is in coils; if the same material were in straight lengths, it would likely be classified as a rod under heading 74.07. Furthermore, the 6 mm threshold is a strict boundary; any wire-like product with a diameter greater than 6 mm falls under subheading 7408.11. This classification ensures that thin, flexible copper conductors are distinguished from heavier industrial rods and bars.

Codes often confused with 7408.19
Common mistake. Refined copper wire under 7408.19 is often misclassified with insulated electric wire under heading 85.44. If the copper wire has been coated with lacquer, enamel, or plastic insulation, it is no longer classified in Chapter 74 but moves to Chapter 85 as an electrical conductor. Another common error is confusing 7408.19 with 7408.11. Subheading 7408.11 is reserved for refined copper wire where the maximum cross-sectional dimension exceeds 6 mm. Importers must also distinguish wire from 'rods' in heading 74.07; while both can have similar cross-sections, wire must be presented in coils, whereas rods are typically in straight lengths. Finally, if the wire is made of a copper alloy (such as brass or bronze) rather than refined copper, it would be classified under subheadings 7408.21 through 7408.29.
Top exporters and importers of HS 740819 (the code used for refined copper wire), 2025
In 2025, the largest exporter of HS 740819 (the code used for refined 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).
