Direct bonded basic bricks and shapes
Direct bonded basic refractory bricks and shapes (magnesia, calcia, chromia)
HSN 6902 10 50 (Direct bonded basic bricks and shapes) 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 may be classified under sibling tariff lines that carry distinct compliance depending on composition and intended industrial application.
The principal importer risk at this tariff line is misclassification: refractory goods containing different elemental compositions or belonging to other subheadings within heading 6902 may attract compliance that does not apply here. Customs re-classification on examination — whether on compositional grounds or end-use declaration — can trigger retrospective duty recovery and detention pending resolution. Importers should verify the precise oxide content (MgO, CaO, Cr2O3 by weight) and bonding method against the tariff description before shipment.
