Product classification
HS code for Tungsten bars: 8101.94
Tungsten (wolfram), unwrought, including bars and rods obtained simply by sintering.
Classification of tungsten bars under HS 8101.94
Tungsten bars are classified under HS code 8101.94, located in Chapter 81, which covers other base metals, cermets, and articles thereof. Tungsten, also known as wolfram, is specifically addressed under heading 8101. The subheading 8101.94 is designated for unwrought tungsten, which includes bars and rods obtained simply by sintering. Sintering is a metallurgical process where powdered tungsten is compacted and heated below its melting point to create a solid mass. In the context of the Harmonized System, unwrought refers to metals in their primary forms, such as ingots, blocks, or bars, that have not been further worked beyond the initial sintering stage. If these bars were to undergo further processing such as rolling, drawing, or machining, they would likely be classified under 8101.99 as wrought articles. The classification is governed by the material purity and its state of manufacture. Under GRI 1, the specific mention of bars and rods obtained simply by sintering in the text of 8101.94 provides a clear path for classification. It is essential to distinguish these from tungsten waste and scrap or tungsten powders, which have their own specific subheadings within the same group.

Codes often confused with 8101.94
Common mistake. Tungsten bars are frequently misclassified under 8101.96, which is for tungsten wire, or 8101.99, which is for wrought tungsten bars that have been further processed. They may also be confused with 2849.90 if the user mistakes the metal for the chemical compound tungsten carbide.
Top exporters and importers of HS 810194 (the code used for tungsten bars), 2025
In 2025, the largest exporter of HS 810194 (the code used for tungsten bars) 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).
