Niobium, Tantalum, and Vanadium Ores and Concentrates

Conflict-mineral due-diligence obligations under the Dodd-Frank Act apply directly to tantalum ores and concentrates (2615906060), making supply-chain documentation a compliance priority for importers of this heading. The US schedule also covers niobium (columbium) ores and concentrates (2615906030), synthetic tantalum-niobium concentrates (2615903000), and vanadium ores and concentrates (2615906090) — each serving distinct industrial roles in steel microalloying, electronics capacitors, and energy-storage applications. Australia leads US imports under this heading, with Singapore, Mexico, and China also among the top suppliers. The presence of China in the supplier mix for these critical minerals warrants monitoring for potential Section 301 exposure.
