Of cylinder capacity not exceeding 250 cc
Compression-ignition vehicle engines, cylinder capacity up to 250 cc
HSN 8408 20 10 (compression-ignition internal combustion piston engines for vehicle propulsion, cylinder capacity not exceeding 250 cc) 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. Diesel engines of larger cylinder capacity, or those used in non-vehicle applications, may fall under sibling tariff lines or Chapter 84 subheadings that attract distinct compliance.
The principal risk at this tariff line is misclassification: engines intended for use in vehicles regulated under Chapter 87 — particularly those subject to motor-vehicle type-approval requirements — may trigger additional clearance obligations that attach at the vehicle level rather than the engine level. Customs re-classification to a higher-capacity subheading or to a non-vehicle engine heading carries the risk of detention pending retrospective compliance. Confirm cylinder displacement, intended end-use, and the precise Chapter 87 vehicle category before filing the bill of entry.
