HS Code 8101.94 – Tungsten (wolfram); unwrought, including bars and rods obtained simply by sintering
HS code 8101.94 is the 6-digit subheading for tungsten (wolfram), unwrought, including bars and rods obtained simply by sintering. It is used for sintered tungsten bars, unwrought tungsten ingots, tungsten rods (sintered), tungsten billets and tungsten powder compacts.
What HS 8101.94 covers
This HS code specifically covers unwrought tungsten, including bars and rods obtained simply by sintering. Sintering is a crucial process for tungsten, transforming powder into dense, solid shapes without full melting, due to its exceptionally high melting point. These unwrought forms serve as fundamental raw materials for further manufacturing into high-performance components. Importers are typically industrial manufacturers in sectors like tooling, aerospace, and electronics, seeking high-purity tungsten for specialized applications. Exporters are often countries with significant tungsten mining and primary processing capabilities. The trade in these forms is driven by the global demand for materials that can withstand extreme conditions, making quality, purity, and consistent dimensions critical for international transactions.

Codes often confused with 8101.94
Common mistake. Can be confused with tungsten waste and scrap (810197) if the unwrought forms are damaged or considered off-spec, or with more processed bars and rods (e.g., 810196 for wire) if further drawing or shaping has occurred.
Top exporters and importers of HS code 810194, 2025
In 2025, the largest exporter of HS code 810194 in UN Comtrade data was China, with 73% of world exports; the largest importer in UN Comtrade data was Japan, with 35% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
