Chrome magnesite bricks
Chrome magnesite refractory bricks for high-temperature applications
HSN 6902 10 20 (Chrome magnesite 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 under Chapter 69 — particularly those classified by silica, alumina, or magnesia content rather than chrome-magnesite composition — may fall under sibling tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line does not extend to all refractory ceramic goods within Chapter 69; bricks and blocks classified by differing mineral compositions or siliceous earths content occupy separate tariff lines that may attract applicable Indian Standards. Customs re-classification — for instance, where chrome or magnesia content is disputed on examination — triggers retrospective compliance and detention pending resolution. Importers should support each consignment with a mill certificate or material test report confirming the oxide composition that grounds the 6902 10 20 classification.
