For motor cars
Spark-ignition petrol engines for motor cars, 250 cc to 1,000 cc
HSN 8407 33 10 (spark-ignition reciprocating piston engines of 250 cc to 1,000 cc, for motor cars) 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 engine categories within Chapter 84 — including engines of larger cylinder capacity or engines for non-passenger vehicles — may classify under sibling tariff lines that carry distinct compliance requirements.
The absence of product-specific compliance at this tariff line does not shield an importer from re-classification risk: customs examination that reveals a cylinder capacity outside the 250 cc to 1,000 cc band, or an end-use other than motor cars, will trigger reclassification to a different tariff line and may attract retrospective compliance obligations. Engine specifications — displacement, ignition type, and declared vehicle application — must align precisely with the tariff description. Detention pending re-classification and retrospective duty recovery are the principal exposure.
