Vermiculite insulation bricks
Vermiculite insulation bricks for refractory applications
HSN 6902 90 30 (Vermiculite insulation bricks) 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, bill of entry, commercial invoice, packing list. Other refractory ceramic constructional goods within Chapter 69 — particularly those classified by chemical composition or intended for specific industrial furnace applications — may fall under sibling tariff lines that carry compliance obligations.
The absence of compliance at this tariff line does not extend to the broader Chapter 69 refractory goods family; bricks or blocks classified by silica, alumina, or magnesia content, or those meeting specific IS performance standards for industrial use, may attract product-certification requirements at a more specific tariff line. Re-classification on customs examination — for example, based on declared chemical composition or end-use — triggers retrospective compliance and detention pending resolution. Verify the precise mineral composition and intended application against the customs tariff before relying on the absence of compliance here.
