Duty Rate (from China)
Products classified under Tariff item 2529.21.00
Acid Grade Fluorspar Lump
Acid grade fluorspar in lump form, containing approximately 97% calcium fluoride by weight. This natural mineral is used primarily in the production of hydrofluoric acid for industrial chemical processes, and its calcium fluoride content does not exceed 97%, placing it under this tariff item.
Ceramic Fluorspar Powder
Ground fluorspar powder with a calcium fluoride content of 96% by weight, used in ceramic glazes and enamels to improve fluidity. The product is natural fluorspar that has been ground, and its CaF2 content is at or below 97%, making it classifiable under this tariff item.
Fluorspar Briquettes Low Grade
Compressed low-grade fluorspar briquettes containing 94% calcium fluoride, formed for easier handling in aluminum smelting. The briquettes are agglomerated fluorspar not further worked, and the CaF2 content is below 97%, so they are classified under this tariff item.
Fluorspar Gravel 95% CaF2
Natural fluorspar gravel screened to 3-10mm with 95% calcium fluoride content, used as a flux in phosphate fertilizer production. The product is in granular crude form, and its CaF2 content is below 97%, making it classifiable under this tariff item.
Metallurgical Grade Fluorspar Fines
Crushed fluorspar fines with a calcium fluoride content of 95-97%, used as a fluxing agent in steelmaking to lower melting points. The product is low-grade fluorspar in powder or chunk form, and its CaF2 content does not exceed 97%, placing it under this tariff item.
Raw Fluorspar Chips for HF Production
Chipped fluorspar with a calcium fluoride content of 92-96%, sized 10-50mm for feeding into hydrofluoric acid reactors. This raw material is natural fluorspar in chip form, and its CaF2 concentration is below 97%, making it classifiable under this tariff item.
