Aluminum Reduction Fluorspar Briquettes
Briquetted fluorspar >97% CaF2 for use in aluminum electrolysis cells as electrolyte component. Remains under HTS 2529.22.00.00 as agglomerated natural high-purity mineral, not chemically altered.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard aluminum grade ≤97% CaF2
Purity percentage governs specific fluorspar tariff line.
If complexed with aluminum as alumino-fluorides
Chemical compounds of fluorides classify in Chapter 28.
If agglomerated with binders into built-up shapes
Worked agglomerated products may shift to Chapter 68 articles.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Document briquetting process doesn't involve binders changing composition
• Certify compression strength to verify integrity for customs inspection
• Separate from synthetic cryolite to avoid mixture classification issues
