Others (including powder)
Vermiculite, perlite and chlorites, unexpanded, other forms including powder
HSN 2530 10 90 (vermiculite, perlite and chlorites, unexpanded — other forms including powder) 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. Expanded or processed forms of these minerals, and other mineral substances classified elsewhere in Chapter 25 or 26, may carry distinct compliance obligations.
Unexpanded vermiculite, perlite, and chlorites in powder form occupy a residual tariff line; the principal risk is misclassification where the goods have undergone expansion or further processing, which can attract a separate tariff line with its own compliance profile. Customs re-classification on examination triggers retrospective compliance, including potential detention pending applicable clearances. Confirm that the product has not been expanded or chemically treated before relying on the absence of compliance at this line.
