Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the calcium fluoride content is 97% or less
Fluorspar with lower purity is classified under the sibling tariff item.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify the CaF2 content exceeds 97% with a certificate of analysis
• Ensure the crushing process is purely mechanical and does not involve any chemical additives
• If the product is mixed with other fluxing agents, confirm whether it remains classifiable under this item or as a preparation

Acid Grade Fluorspar Lump
Acid grade fluorspar lumps mined and crushed to contain over 97% calcium fluoride, used primarily as feedstock for hydrofluoric acid production. The product is in a crude state, having only been crushed and screened, with no chemical alteration or heat treatment, aligning with Chapter 25's coverage of natural mineral products.
Aluminum Reduction Fluorspar Briquettes
Fluorspar briquettes formed by agglomeration of high-purity fluorspar (>97% CaF2) for use in aluminum electrolysis cells.
