Aventurine
Aventurine, unworked or simply sawn or roughly shaped
HSN 7103 10 63 (Aventurine, 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. Aventurine that has been further worked, graded, strung, mounted, or set falls under sibling tariff lines within Chapter 71 that may carry distinct classification consequences.
The principal risk at this tariff line is misclassification: aventurine that has been tumbled, shaped beyond rough sawing, or incorporated into jewellery findings shifts to a more processed sub-heading within Chapter 71, and customs re-classification on examination triggers retrospective duty recovery and potential detention. Verify the precise state of working — unworked, sawn, or roughly shaped — against the physical consignment before filing the bill of entry.
