Alumina carbon bricks and shapes
Alumina carbon refractory bricks and shapes
HSN 6902 20 30 (alumina carbon 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 — particularly those of siliceous fossil meals or those falling under different compositional thresholds — may be classified under sibling tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line does not extend to the broader heading: refractory bricks and shapes differing in alumina or silica content, bonding chemistry, or intended furnace application can attract re-classification to a tariff line that does carry compliance. Customs re-classification on examination triggers retrospective duty and may result in detention pending conformity documentation. Verify the precise compositional specification — alumina percentage, carbon content, binder type — against the customs tariff before shipment.
