Tanzanite
Tanzanite, precious and semi-precious stones (unset, unstrung)
HSN 7103 99 52 (Tanzanite) 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 articles within Chapter 71 — including mounted or set stones and articles of precious metal — may carry distinct classification consequences that affect duty liability.
Tanzanite imported already mounted, set, or permanently strung falls outside heading 7103 and into different tariff entries within Chapter 71, each with its own duty structure. Re-classification on customs examination — whether on account of mounting, grading documentation, or declared use — triggers retrospective duty recovery and potential detention. Importers should confirm that stones arrive unset and that grading certificates align with the declared tariff line before shipment.
