Antimony Ores and Concentrates

Antimony is designated a critical mineral by the US government, and its ores and concentrates — classified entirely under the single line 2617100000 — feed downstream production of flame retardants, lead-acid battery alloys, and semiconductor compounds. Mexico is the top foreign supplier to the US, followed by India and Kazakhstan, providing geographic diversification from China, which dominates global mine production but does not appear among the recorded top US suppliers at this stage of processing. Importers should monitor trade-remedy developments, as antimony supply chains have drawn increasing policy attention given the mineral's critical-material designation.
