HS Code 7505.21 – Nickel; wire, not alloyed
HS code 7505.21 is the 6-digit subheading for nickel, wire, not alloyed. It is used for pure nickel welding wire, unalloyed nickel resistance wire, nickel battery lead wire, pure nickel electrical wire and fine pure nickel wire.
What HS 7505.21 covers
This category encompasses pure, unalloyed nickel in the form of wire, typically produced by drawing from rods. These wires are valued for their excellent electrical conductivity, corrosion resistance, and ductility, making them suitable for a range of specialized applications. They are commonly used in electronics, heating elements, battery components, and as welding filler material where high purity is essential. Major importers include countries with significant electronics manufacturing, battery production, and specialized engineering industries, such as China, the United States, Germany, and Japan. Exporters are typically nations with established wire drawing capabilities and access to high-purity nickel, including Canada, Russia, and various European countries. Key trade considerations involve wire diameter, surface finish, tensile strength, and packaging, as these factors are critical for downstream manufacturing processes.

Codes often confused with 7505.21
Common mistake. This code is distinct from unalloyed nickel bars/rods (750511) by its specific wire form, and from nickel alloy wire (750522) by the absence of alloying elements.
Top exporters and importers of HS code 750521, 2025
In 2025, the largest exporter of HS code 750521 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).
