Duty Rate (from China)
Products classified under Tariff item 2529.21
Acid Grade Fluorspar Lump
Acid grade fluorspar in lump form containing approximately 97% calcium fluoride (CaF2), extracted from natural mineral deposits. It is used primarily in the production of hydrofluoric acid for industrial chemical processes. This product falls under tariff item 2529.21.00 as it is fluorspar with a calcium fluoride content by weight of 97% or less, and it has not undergone any processing beyond crushing or grinding as permitted by Chapter 25 notes.
2529.21.00Ceramic Fluorspar Powder
Ground fluorspar powder with a calcium fluoride content of 96% by weight, processed by milling natural fluorspar. It is used in ceramic glazes and enamels to improve fluidity during firing. This product is classified under tariff item 2529.21.00 because it is natural fluorspar with CaF2 content at or below 97%, and grinding is a permitted mechanical process under Chapter 25 notes.
2529.21.00Fluorspar Briquettes Low Grade
Compressed low-grade fluorspar briquettes containing 94% calcium fluoride, formed by agglomeration for easier handling in aluminum smelting. The briquettes are not further worked after compression and maintain a CaF2 content below 97%. This product falls under tariff item 2529.21.00 as agglomerated fluorspar not exceeding the specified purity threshold.
2529.21.00Fluorspar Gravel 95% CaF2
Natural fluorspar gravel screened to a 3-10mm particle size with a calcium fluoride content of 95%, used as a flux in phosphate fertilizer production. The gravel is in a crude granular state, having only been screened, which is a permitted mechanical process under Chapter 25 notes. It is classified under tariff item 2529.21.00 due to its CaF2 content of 97% or less.
2529.21.00Metallurgical Grade Fluorspar Fines
Crushed fluorspar fines with a calcium fluoride content ranging from 95% to 97%, used as a fluxing agent in steelmaking to lower melting points. The fines are produced by crushing natural fluorspar and have not undergone any processing beyond mechanical size reduction. This product is classified under tariff item 2529.21.00 as low-grade fluorspar not exceeding 97% calcium fluoride by weight.
2529.21.00Raw Fluorspar Chips for HF Production
Chipped fluorspar with a calcium fluoride content of 92-96%, sized uniformly at 10-50mm for feeding into hydrofluoric acid reactors. The chips are in a crude state, having only been chipped and screened, which are permitted mechanical processes under Chapter 25 notes. This product falls under tariff item 2529.21.00 due to its sub-97% calcium fluoride concentration.
