Product classification
HS code for Unwrought tungsten: 8101.94
Tungsten (wolfram), unwrought, including bars and rods obtained simply by sintering.
Classification of unwrought tungsten under HS 8101.94
Tungsten, also known as wolfram, is a dense metal with the highest melting point of all elements in pure form. It is classified under HS code 8101.94 when it is in an unwrought state, which includes bars and rods obtained simply by sintering. Chapter 81 of the Harmonized System covers "Other base metals; cermets; articles thereof," and heading 8101 is specifically for tungsten. The classification logic follows the progression from raw material to finished product. Subheading 8101.94 is unique because it explicitly includes bars and rods that have been produced through sintering—a process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction—provided they have not been further worked. This distinguishes them from wrought bars and rods which would be classified elsewhere. Accurate classification is essential for applying the correct tariff rates and complying with trade regulations regarding strategic metals.

Codes often confused with 8101.94
Common mistake. Tungsten classification can be complex due to the inclusion of sintered products in 8101.94. Many traders mistakenly classify sintered rods under 8101.96 (wire) or 8101.99 (other articles) because they appear to be "finished" shapes. However, if the rods are obtained "simply by sintering" without further drawing or machining, 8101.94 is the correct code. Another area of confusion is tungsten carbide, which is a cermet. Tungsten carbide powders and articles are classified under 8113.00 or within Chapter 38 depending on the preparation. Pure tungsten powders are also sometimes incorrectly placed in 8101.94 instead of the more specific 8101.10.
Top exporters and importers of HS 810194 (the code used for unwrought tungsten), 2025
In 2025, the largest exporter of HS 810194 (the code used for unwrought tungsten) 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.

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).
