U.S. imports of tungsten (wolfram) ores and concentrates (SITC 28792) totaled $30.2M in April 2026, traded with 12 countries.
Importers of Tungsten (Wolfram) Ores and Concentrates paid $145K in duties in April 2026 — an effective duty rate of 0.7% on $21.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Tungsten (Wolfram) Ores and Concentrates imports of $30.2M in April 2026 ran 63% above the year-to-date monthly average of $18.6M.
Last updated: April 2026 dataWolframite and scheelite are the two ore minerals that feed the global tungsten supply chain, with concentrates processed into ammonium paratungstate (APT) as the primary intermediate before conversion to tungsten metal, carbide, and alloys used in cutting tools, drill bits, and armor-penetrating applications. China's dominant position in tungsten mining and processing has prompted US government attention to supply-chain resilience for this critical mineral, and importers should monitor any Section 232 or other national-security-related trade measures that may be applied to tungsten-bearing materials. Concentrate grade is typically expressed as WO₃ content, and contracts should specify minimum assay thresholds to ensure suitability for downstream APT conversion.

The US Geological Survey designates tungsten as a critical mineral due to its essential role in defense and industrial applications and the high geographic concentration of supply. Importers and end users should track US government critical-minerals initiatives, potential stockpiling programs, and any evolving trade-remedy or export-control measures from major producing countries that could affect availability and pricing.
Standard entry documentation includes a commercial invoice with WO₃ assay results, a certificate of origin, a packing list, and a bill of lading. Because tungsten is a critical mineral with national-security relevance, some shipments may receive enhanced CBP scrutiny. Importers should also confirm whether the exporting country has any export licensing requirements for tungsten concentrates, as these can delay shipment.
