Import Tips & Compliance
• Confirm the powder is not mixed with other substances, as mixing would exclude it from Chapter 25
• Ensure the CaF2 content exceeds 97% by weight and include lab results
• Verify that grinding is the only processing step, without calcination or roasting

Acid Grade Fluorspar Lump
Acid Grade Fluorspar Lump consists of high-purity fluorspar lumps containing over 97% calcium fluoride, mined and crushed for industrial use in hydrofluoric acid production. This raw material falls under tariff item 2529.22.00 due to its exceptional calcium fluoride content and unprocessed state, which aligns with the chapter's coverage of crude or mechanically processed minerals.
Aluminum Reduction Fluorspar Briquettes
Aluminum Reduction Fluorspar Briquettes are briquetted fluorspar with over 97% CaF2, used as an electrolyte component in aluminum electrolysis cells. They remain under tariff item 2529.22.00 as agglomerated natural high-purity mineral, not chemically altered, consistent with the chapter's allowance for mechanical processes like agglomeration.
Ceramic Flux Fluorspar Granules
Ceramic Flux Fluorspar Granules are granulated fluorspar with over 97% calcium fluoride, serving as a flux in ceramic tile production. They are classified under tariff item 2529.22.00 because they are in a natural high-purity state before further processing, and granulation is a mechanical process permitted by Chapter 25 notes.
Chemical Grade Fluorspar 98%
Chemical Grade Fluorspar 98% is premium chemical-grade fluorspar assayed at 98%+ CaF2 for fluorine compound synthesis.
