Product classification
HS code for Cupro-nickel wire: 7408.22
Copper, wire, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver).
Classification of cupro-nickel wire under HS 7408.22
Cupro-nickel wire is classified under HS code 7408.22. This code is part of Chapter 74, which covers copper and articles thereof. Heading 7408 is dedicated to copper wire, and the subheading 7408.22 specifically identifies wire made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). To be classified here, the product must meet the definition of "wire" provided in the Chapter 74 notes: 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, or other polygons. The alloy composition is the deciding factor for this subheading; cupro-nickel alloys are valued for their resistance to corrosion, particularly in marine environments, and their electrical conductivity properties, which distinguishes them from refined copper wire or other copper alloys like brass or bronze.

Codes often confused with 7408.22
Common mistake. Cupro-nickel wire is often misclassified under 7408.11 or 7408.19, which are reserved for wire of refined copper (non-alloyed). It may also be confused with 7408.21, which is for copper-zinc base alloys (brass). Furthermore, if the nickel content exceeds the copper content by weight, the product would be classified under Chapter 75 (Nickel) rather than Chapter 74, specifically under 7505.22 for nickel alloy wire.
Top exporters and importers of HS 740822 (the code used for cupro-nickel wire), 2025
In 2025, the largest exporter of HS 740822 (the code used for cupro-nickel wire) in UN Comtrade data was Germany, with 30% of world exports; the largest importer in UN Comtrade data was India, with 18% 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).
