HS Code 8101.99 – Tungsten (wolfram); articles n.e.c. in heading no. 8101
HS code 8101.99 is the 6-digit subheading for tungsten (wolfram), articles n.e.c. in heading no. 8101. It is used for tungsten crucibles, tungsten radiation shielding, tungsten counterweights, tungsten heating elements (finished) and tungsten contacts.
What HS 8101.99 covers
This residual HS code covers various finished or semi-finished articles of tungsten (wolfram) not specifically classified elsewhere under heading 8101. It encompasses a broad spectrum of products where tungsten's unique properties—such as extreme density, hardness, high melting point, and radiation shielding capabilities—are utilized. This includes specialized components for aerospace, medical devices, industrial furnaces, and defense applications. Importers are typically high-tech manufacturers and industries requiring custom-engineered solutions. Exporters are often specialized fabricators with advanced capabilities in machining and forming refractory metals. The trade in these articles is characterized by high value, precision manufacturing, and adherence to strict performance specifications, reflecting their critical role in demanding, high-performance environments.

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).
