Ruby
Ruby, worked or unworked, unstrung and unmounted
HSN 7103 91 10 (Ruby) 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. Rubies mounted in jewellery or set in articles of precious metal fall under different tariff lines within Chapter 71 that may carry distinct treatment for valuation and, where applicable, hallmarking compliance.
The principal risk at this tariff line is misclassification — between unworked rough ruby, worked but unset ruby, and ruby that has been strung or mounted, each of which may map to a different 8-digit position within Chapter 71. Customs re-classification on examination triggers retrospective duty recovery and potential detention. Importers should document the precise processing state and confirm that the stone is neither strung nor mounted before relying on this tariff line.
