HS Code 7505.22 – Nickel; wire, of nickel alloys
HS code 7505.22 is the 6-digit subheading for nickel, wire, of nickel alloys. It is used for inconel welding wire, hastelloy spring wire, monel resistance wire, nimonic alloy wire and nickel-chromium heating wire.
What HS 7505.22 covers
This HS code covers wire made from various nickel alloys, which are specifically formulated to provide enhanced properties such as high-temperature strength, superior corrosion resistance, or specific electrical characteristics. These alloy wires are critical components in demanding applications across industries like aerospace, medical devices, chemical processing, and specialized electronics. They are used in heating elements, springs, fasteners, and as welding filler metals for joining high-performance alloys. Major importers are countries with advanced manufacturing sectors that require these specialized materials, including the United States, Germany, Japan, and China. Exporters are typically specialized manufacturers in nations with strong metallurgical expertise, such as the United States, Germany, and the United Kingdom. Trade in these products is highly dependent on precise specifications, including alloy composition, wire gauge, mechanical properties, and certifications for critical applications.

Codes often confused with 7505.22
Common mistake. This code is differentiated from unalloyed nickel wire (750521) by the presence of alloying elements, and from other nickel alloy semi-finished products (e.g., 750512) by its specific wire form.
Top exporters and importers of HS code 750522, 2025
In 2025, the largest exporter of HS code 750522 in UN Comtrade data was the United States, with 19% of world exports; the largest importer in UN Comtrade data was Germany, with 15% 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).
