Calcium Fluoride Lump
Natural or synthetic calcium fluoride lumps (fluorspar) serve as raw material for HF production and steel fluxing. HTS 2826.19.90.00 covers this as other fluorides when chemically defined.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crude natural fluorspar under 97% purity
Natural mineral fluorspar classifies in Chapter 25, not refined chemicals.
If converted to hydrogen fluoride acid
Derived acids from fluorides move to subchapter II headings like 2811.

Import Tips & Compliance
• Differentiate from crude fluorspar (2529.22); lab test for >97% CaF2 content
• Declare metallurgical vs acid grade to match correct statistical suffix
• Bulk shipments need proper ventilation to avoid moisture absorption
