Product classification
HS code for Tungsten rods: 8101.94
Tungsten (wolfram), unwrought, including bars and rods obtained simply by sintering.
Classification of tungsten rods under HS 8101.94
Tungsten rods are classified under HS code 8101.94. This code specifically covers tungsten in its unwrought form, including bars and rods that have been obtained simply by the process of sintering. Sintering is the standard metallurgical process for tungsten, where powder is compressed and heated to form a solid mass without reaching the melting point. According to the Explanatory Notes to Chapter 81, bars and rods that have not been further worked than sintering are considered unwrought. If the rods undergo further processing such as rolling, drawing, or machining, they may transition to other sub-headings, but the primary sintered form remains under 8101.94.

Codes often confused with 8101.94
Common mistake. Tungsten rods are often misclassified under 8101.99 if the importer assumes they are finished "articles." However, 8101.94 is more specific for the unwrought, sintered state. Another common error is using 7202.80, which is for ferro-tungsten; this is incorrect because 8101.94 is for the nearly pure metal or specific tungsten alloys, not the ferro-alloy used in steelmaking. Finally, if the rod is used as a welding electrode, it might be confused with 8515.90, but 8101.94 is preferred for the material form.
Top exporters and importers of HS 810194 (the code used for tungsten rods), 2025
In 2025, the largest exporter of HS 810194 (the code used for tungsten rods) 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).

Questions about tungsten rods
What is the HS code for Tungsten rods?
The HS code for Tungsten rods is 810194 (Tungsten (wolfram); unwrought, including bars and rods obtained simply by sintering). The HS code for tungsten rods that are unwrought or simply sintered is 8101.94.
How do I classify Tungsten rods for customs?
Tungsten rods is classified under HS code 810194 — Tungsten (wolfram); unwrought, including bars and rods obtained simply by sintering. This is a 6-digit subheading level code.
What if the tungsten rod is polished or threaded?
If the rod has been further worked by polishing, threading, or precise machining, it is no longer considered "unwrought" and should be classified under HS code 8101.99.
Which countries are the top exporters of tungsten rods (HS 810194)?
In 2025, the top exporters of HS 810194 (the code used for tungsten rods) in UN Comtrade data were China ($117M, 73% of world exports), the United Kingdom ($11M) and Vietnam (about $7.9M). World exports came to about $161M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
