Product classification
HS code for Tungsten powder: 8101.10
Tungsten (wolfram), articles thereof, including waste and scrap, powders.
Classification of tungsten powder under HS 8101.10
Tungsten powder is classified under HS code 810110, which falls within Chapter 81 covering "Other base metals; cermets; articles thereof." This specific subheading is reserved for tungsten in its primary powder form. The classification is determined by the physical state of the metal. Tungsten powder is typically produced through the hydrogen reduction of tungsten blue oxide or tungstic acid. Unlike ores in Chapter 26, this material has undergone extensive chemical refinement to reach a high level of purity, often exceeding 99.9%. It serves as the precursor for manufacturing tungsten wire, sheets, and cemented carbides. The General Rules of Interpretation (GRI) dictate that metals in their primary forms, including powders, are classified based on their elemental composition. As long as the powder consists predominantly of tungsten and is not mixed with binders for the purpose of forming carbides, it remains in 810110. The particle size distribution and purity levels are key technical specifications for this code, as they determine the powder's suitability for powder metallurgy. This code excludes powders that have been prepared for use as pigments or in the manufacture of paints, which would fall under Chapter 32. The classification is essential for monitoring the trade of high-purity metals used in aerospace and defense.

Codes often confused with 8101.10
Common mistake. Tungsten powder is often confused with tungsten carbide powder, which is classified under HS code 284990. The difference is chemical: 810110 is for the metallic element, while 284990 is for the chemical compound of tungsten and carbon. Additionally, mixtures of metal carbides (unfused) are classified under 382430, which is another frequent point of confusion. Importers must also distinguish this from unwrought tungsten in blocks or bars, which falls under 810194.
Top exporters and importers of HS 810110 (the code used for tungsten powder), 2025
In 2025, the largest exporter of HS 810110 (the code used for tungsten powder) in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was the United States, with 26% 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).
