Of tungsten carbide
Tungsten carbide balls, needles, and rollers for bearings
HSN 8482 91 12 (tungsten carbide balls, needles, and rollers for ball or roller bearings) 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. Complete ball or roller bearings, as opposed to their constituent rolling elements, are classified elsewhere within Chapter 84 and may attract distinct compliance obligations.
The absence of compliance at this tariff line applies specifically to unassembled rolling elements of tungsten carbide; finished bearings and bearing assemblies are classified under separate subheadings within Chapter 84 and may carry Quality Control Order coverage. Re-classification by customs from rolling elements to finished bearings — or to a different material grade — triggers retrospective compliance, including detention pending the relevant licence. Importers should confirm material composition certificates and intended use documentation before the goods arrive at port.
