Spark-ignition piston engines, 50–250 cc, for motorcycles
HSN 8407 32 10 (spark-ignition reciprocating piston engines of 50–250 cc cylinder capacity, for motorcycles) 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. Engines of a different cylinder capacity, or those intended for vehicles other than motorcycles, may fall under sibling tariff lines within Chapter 84 that carry distinct compliance obligations.
The absence of compliance at this tariff line does not insulate an importer from retrospective risk if customs re-classifies the engine — whether on cylinder capacity grounds (exceeding 250 cc moves the goods to a higher subheading) or on end-use grounds (engines declared for motorcycles but destined for other vehicles). Re-classification on examination triggers retrospective compliance and potential detention. Verify the declared cylinder capacity and the intended vehicle type against the technical specification sheet before filing the bill of entry.
