Last updated: April 2026 dataTungsten's exceptional hardness and high-temperature strength make ferrotungsten and its silicon-bearing variant critical alloying additions for high-speed tool steels, die steels, and wear-resistant alloys. Both forms enter under a single tariff line (7202800000). Vietnam and Germany are the leading US import sources under this heading — Vietnam reflecting its growing role in tungsten concentrate and intermediate processing, Germany its established specialty ferroalloy refining capacity. Imports of tungsten-bearing products from China are subject to Section 301 tariffs, a factor that has meaningfully shaped sourcing patterns for this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
China is a major global producer of tungsten intermediates, but imports from China are subject to Section 301 tariffs, increasing landed costs for Chinese-origin ferrotungsten. This has incentivized US buyers to source from Vietnam, Germany, and other suppliers, though buyers should verify current Section 301 coverage and any applicable exclusions with a licensed customs broker.
Both products are classified under the same HTS heading (720280) and tariff line (7202800000), so the distinction does not affect duty treatment. Commercially, ferrosilicon tungsten contains a deliberate silicon addition alongside tungsten, which can be advantageous in certain melt shop practices where simultaneous deoxidation is desired. The producer's chemical analysis will confirm which form is being supplied.
