Containing by weight more than 97% of calcium fluoride
Fluorspar containing more than 97% calcium fluoride by weight
HSN 2529 22 00 (fluorspar containing by weight more than 97% of calcium fluoride) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Fluorspar of lower calcium fluoride content falls under a sibling tariff line within heading 2529, and correct classification depends on verified assay documentation.
The principal importer risk at this tariff line is misclassification: fluorspar with 97% or less calcium fluoride content is classified separately within heading 2529, and a customs re-examination that disputes the assay grade can trigger retrospective compliance and detention pending re-classification. Purity certificates and third-party assay reports should accompany the shipment and be retained in the import file. Chapter 25 as a whole is generally low-regulation, but downstream fluorochemical derivatives attract separate chapter-level compliance.
