Prehnite
Prehnite, unworked or simply sawn or roughly shaped
HSN 7103 10 61 (Prehnite, unworked or simply sawn or roughly shaped) 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 tariff lines within Chapter 71 — covering worked, mounted, or set gemstones — may attract distinct compliance and valuation scrutiny, making classification accuracy the principal importer risk.
The absence of compliance at this tariff line applies specifically to prehnite in its unworked or simply sawn or roughly shaped form; prehnite that has been cut, polished, or set falls under a different tariff line within Chapter 71 and warrants separate classification review. Customs officers routinely scrutinise gemstone consignments for misclassification between worked and unworked states, and re-classification on examination triggers retrospective duty recovery and potential detention. Confirm the precise state of working — and obtain supporting gemmological documentation where available — before relying on this tariff line.
