Product classification
HS code for Thick copper wire: 7408.11
Copper, wire, of refined copper, of which the maximum cross-sectional dimension exceeds 6mm.
Classification of thick copper wire under HS 7408.11
Thick copper wire is classified under HS code 7408.11. This code is situated within Chapter 74, which encompasses copper and articles thereof. Heading 7408 is dedicated to copper wire, which is defined 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. For the purpose of subheading 7408.11, the wire must be made of refined copper and possess a maximum cross-sectional dimension exceeding 6mm. This classification is strictly based on the material composition (refined copper) and the physical dimensions (thickness). Refined copper is defined in Note 1(a) to Chapter 74 as metal containing at least 99.85% by weight of copper, or metal containing at least 97.5% by weight of copper, provided that the content by weight of any other element does not exceed certain limits. The classification process follows GRI 1 and GRI 6, ensuring that the product meets both the heading definition for wire and the subheading requirement for size and purity. This wire is typically used as a raw material for further drawing or as a heavy-duty conductor in electrical grounding and industrial applications.

Codes often confused with 7408.11
Common mistake. Thick copper wire is often confused with copper bars and rods under HS code 7407.10. The primary difference is that wire must be in coils, whereas bars and rods are typically straight lengths. Additionally, if the wire has a maximum cross-sectional dimension of 6mm or less, it must be classified under 7408.19. Another common misclassification is 8544.49 for insulated wire; if the copper wire has any plastic, rubber, or enamel coating, it moves to Chapter 85.
Top exporters and importers of HS 740811 (the code used for thick copper wire), 2025
In 2025, the largest exporter of HS 740811 (the code used for thick copper wire) in UN Comtrade data was Germany, with 15% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 8.9% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
