U.S. imports of niobium, tantalum & vanadium ores and concentrates (HS 261590) totaled $4.4M in April 2026, traded with 5 countries.
Niobium, Tantalum & Vanadium Ores and Concentrates imports of $4.4M in April 2026 ran 12% below the year-to-date monthly average of $4.9M.
Last updated: April 2026 dataThree strategically important metals — niobium (columbium), tantalum, and vanadium — share this heading, each with distinct industrial roles: niobium strengthens high-strength low-alloy steel, tantalum is essential for capacitors in electronics, and vanadium is used in vanadium redox flow batteries and tool steels. The US schedule enumerates them separately at lines 2615906030 (niobium), 2615906060 (tantalum), and 2615906090 (vanadium), with synthetic tantalum-niobium concentrates at 2615903000. Australia leads US imports under this heading. Tantalum sourcing is subject to conflict-mineral due-diligence expectations under Dodd-Frank Section 1502, which requires downstream manufacturers to trace supply chains through smelters.

Dodd-Frank Section 1502 requires SEC-reporting companies to conduct due diligence on tantalum (along with tin, tungsten, and gold) sourced from conflict-affected regions of the Democratic Republic of Congo and adjoining countries. While the obligation falls on downstream manufacturers rather than importers directly, tantalum ore buyers are typically required by customers to provide smelter-of-origin documentation consistent with the Responsible Minerals Initiative (RMI) framework.
Neither country is a primary mining nation for these metals. Their appearance reflects trading-hub and specialty-chemical intermediary roles: Singapore is a major commodity re-export center, and Liechtenstein hosts specialty materials companies that process or trade refined mineral products. Importers should verify country of origin carefully, as the country of export may differ significantly from where the ore was actually mined.
