Last updated: April 2026 dataFluorspar (calcium fluoride) is classified by fluorite content into acid-grade and metallurgical-grade streams, and that distinction drives its end-use across hydrofluoric acid production, aluminum smelting flux, and steel refining. Acid-grade fluorspar, typically above 97% CaF₂, is the primary feedstock for fluorochemicals including refrigerants and fluoropolymers, making it a strategically watched mineral in US industrial policy. Import volumes are sensitive to domestic HF production capacity and to trade-remedy measures that have historically applied to certain supplier countries.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Acid-grade fluorspar contains at least 97% calcium fluoride and is processed into hydrofluoric acid, the gateway chemical for fluoropolymers and refrigerants. Metallurgical-grade typically runs 60–85% CaF₂ and is used directly as a flux in steel and aluminum production. The grade determines both the applicable tariff treatment and the downstream buyer.
Yes — antidumping and countervailing duty orders have been applied to fluorspar from certain countries in the past. Importers should verify the current status of any orders with US Customs and Border Protection before contracting, as duty liability can be substantial and retroactive.
