Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for standard-grade HF feedstock with lower purity
97% CaF2 threshold separates acid-grade from metallurgical fluorspar.
If converted to hydrofluoric acid
Final chemical products classify under inorganic acids, not source minerals.
If containing micaceous iron oxides or other impurities
Mixed earth minerals fall under 2530 per chapter provisions.
