Powder
Feldspar in powder form
HSN 2529 10 20 (feldspar powder) 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 (IEC), bill of entry, commercial invoice, packing list. Other mineral-based materials within Chapter 25 — including fluorspar and nepheline syenite classified under adjacent headings — may carry distinct compliance obligations depending on their form and intended use.
The principal risk for feldspar powder imports lies in misclassification: lump or granular feldspar falls under a separate tariff line within Chapter 25, and ceramics-grade versus glass-grade specifications sometimes prompt customs officers to query the correct sub-heading. A re-classification on examination triggers retrospective compliance and detention pending resolution. Verify the physical form and purity specification of the consignment against the customs tariff before shipment.
