Last updated: August 2026 dataTungsten in unwrought form — including bars and rods produced simply by sintering tungsten powder — is a strategic refractory metal used in cutting tools, electrical contacts, radiation shielding, and defense applications. China dominates global supply and is the leading US source under this heading, a concentration that has drawn sustained attention from supply-chain risk managers; Vietnam and Canada are secondary suppliers. Imports from China are subject to Section 301 tariffs, and the strategic nature of tungsten has prompted ongoing US government interest in supply diversification.

Unwrought tungsten under 810194 covers primary metal forms — including sintered bars and rods produced directly from powder metallurgy without further working — as well as scrap. Tungsten that has been drawn into wire, rolled into sheet, or machined into finished parts classifies in other subheadings of Chapter 81 or in the relevant finished-goods chapter.
The heading explicitly includes bars and rods 'obtained simply by sintering,' meaning powder-metallurgy consolidation alone does not move the product out of the unwrought category. However, if sintered bars are subsequently drawn, swaged, or otherwise mechanically worked, they would reclassify into the worked tungsten subheadings.
