Lumps
Feldspar in lump form
HSN 2529 10 10 (Feldspar, lumps) 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. Other minerals and processed mineral products within Chapter 25 may carry distinct compliance depending on form and intended use, so classification accuracy remains the principal importer risk.
The absence of compliance at this tariff line applies specifically to feldspar in lump form; feldspar powder or other processed forms are classified separately and may attract different treatment on customs examination. Re-classification on examination — for instance, from lumps to a finely ground or beneficiated grade — triggers retrospective compliance, including potential detention pending clearance. Verify the physical form and processing state of the consignment against the customs tariff before relying on the absence of compliance at this line.
