Magnesite chrome refractory bricks and shapes
HSN 6902 10 30 (Magnesite chrome 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 classified by a different dominant oxide 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 products within Chapter 69: bricks and shapes classified by a different elemental basis — silica, alumina, or dolomite — occupy separate tariff lines and may attract their own compliance regimes. Customs re-classification based on oxide composition or MgO/CaO/Cr2O3 content verified at examination triggers retrospective compliance and potential detention. Importers should confirm the precise oxide assay against the applicable subheading threshold before filing the bill of entry.
