U.S. imports of tungsten ores and concentrates (HS 261100) totaled $66.4M in July 2026, traded with 14 countries.
Importers of Tungsten Ores and Concentrates paid $52K in duties in July 2026 — an effective duty rate of 0.1% on $37.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Tungsten Ores and Concentrates imports of $66.4M in July 2026 ran 108% above the year-to-date monthly average of $31.9M.
Last updated: July 2026 dataTungsten ores and concentrates — classified as either crude ores (2611003000) or processed concentrates (2611006000) — are a strategically sensitive import given tungsten's designation as a critical mineral by the US government and its essential role in cemented carbide tooling, armor-piercing ammunition, and high-temperature alloys. Bolivia leads US import supply, followed by Spain and Portugal, a European sourcing pattern that reflects efforts to diversify away from China, which dominates global tungsten mining but does not appear among the top US suppliers for this heading. The ore-versus-concentrate distinction is determined by the degree of beneficiation, with concentrates typically reporting tungsten trioxide equivalent content above defined thresholds.

Tungsten ores (2611003000) are materials extracted from the mine with minimal processing beyond crushing and sizing, while concentrates (2611006000) have undergone beneficiation — such as gravity separation, flotation, or magnetic separation — to increase the tungsten content, typically expressed as WO₃ equivalent. The degree of processing and the resulting WO₃ grade are the key classification criteria, and a certificate of analysis from the producer is the standard supporting document.
Bolivia's tungsten production is concentrated in a small number of mining operations, creating potential concentration risk for US importers. Logistical lead times from landlocked Bolivia add complexity compared to European suppliers like Spain and Portugal. Importers relying on Bolivian supply should monitor production output, export licensing requirements in Bolivia, and freight routing options through Chilean or Peruvian ports to manage supply continuity.
