In lumps
Quartzite in lump form, unprocessed or roughly trimmed
HSN 2506 20 10 (Quartzite in 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. Quartzite in other physical forms — blocks or slabs of rectangular shape, or processed quartz products — may fall under sibling tariff lines within Chapter 25 that carry distinct compliance considerations.
The absence of compliance at this tariff line reflects the raw, unprocessed lump form of quartzite; downstream processed forms — slabs, tiles, or dimensioned blocks — and quartz used as an industrial mineral input may be classified differently within Chapter 25 or adjacent chapters. Re-classification by customs on examination, for instance to a more specific form-based tariff line, triggers retrospective compliance and potential detention. Confirm the physical form, degree of working, and intended end-use before relying on this tariff line.
