Prehnite
Prehnite, a semi-precious stone, unset and unstrung
HSN 7103 99 41 (Prehnite) 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 goods within Chapter 71 — including precious metals, articles of jewellery, or strung and mounted stones — may attract separate compliance obligations.
The principal importer risk at this tariff line is misclassification: prehnite that has been strung, mounted, or set moves outside the scope of HSN 7103 99 41 into a different heading within Chapter 71, which may carry distinct duty rates and compliance requirements. Customs re-classification on examination can result in detention pending re-assessment and retrospective duty recovery. Confirm the precise physical state — worked or unworked, graded or ungraded, strung or unstrung — against the customs tariff before filing the bill of entry.
