Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If regular steel flux grades ≤97% purity
High-purity requirement splits fluorspar into distinct tariff subheadings.
If derived from phosphatic residues
Granulated slag from mineral processing has separate classification.
If flux chemically prepared with additives
Prepared chemical fluxes move out of Chapter 25 minerals.
