Product classification
HS code for Nickel wire: 7505.21
Nickel, wire, not alloyed.
Classification of nickel wire under HS 7505.21
Nickel wire is classified under HS code 7505.21 within the category of nickel bars, rods, profiles, and wire. The Harmonized System defines wire as cold-formed products, in coils, of any cross-sectional shape, which do not conform to the definition of bars or rods. For classification under 7505.21, the wire must be composed of non-alloyed nickel. This means the nickel content must meet the high purity standards (99%+) specified in the legal notes of Chapter 75. The manufacturing process usually involves drawing the metal through a series of dies to achieve the desired diameter. This wire is frequently utilized in electronics, heating elements, and as a component in various industrial meshes. It is distinguished from bars and rods primarily by its packaging (coils) and its cross-sectional dimensions. The classification is determined by the material (non-alloyed nickel) and the form (wire in coils).

Codes often confused with 7505.21
Common mistake. Nickel wire is often misclassified under 7505.22, which is the code for alloyed nickel wire. If the wire contains more than 1% of any other element (excluding cobalt up to 1.5%), it must be classified as an alloy. Another common error is using 8544 for insulated nickel wire. If the wire is coated with plastic or enamel for electrical insulation, it moves to Chapter 85. Furthermore, if the nickel wire is not in coils but in straight lengths, it may be classified as a bar or rod under 7505.11. It is essential to verify both the chemical composition and the physical state (coiled vs. straight) before assigning the code.
Top exporters and importers of HS 750521 (the code used for nickel wire), 2025
In 2025, the largest exporter of HS 750521 (the code used for nickel wire) in UN Comtrade data was Austria, with 26% of world exports; the largest importer in UN Comtrade data was the United States, with 14% 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).
