Of a cylinder capacity exceeding 250 cc
Marine propulsion diesel engines exceeding 250 cc cylinder capacity
HSN 8408 10 93 (marine propulsion compression-ignition engines exceeding 250 cc cylinder capacity) 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 compression-ignition engines under Chapter 84 — particularly those for vehicles or industrial use — may fall under sibling tariff lines that carry compliance obligations, making accurate end-use classification the principal importer risk.
The absence of compliance at this tariff line does not extend to the broader Chapter 84 family: diesel engines classified for automotive or industrial applications may attract Quality Control Order coverage, and misidentification of end-use on the bill of entry is the most common trigger for re-classification on examination. Customs re-classification to a covered tariff line results in detention pending the relevant licence and retrospective duty recovery. Verify that vessel-use documentation clearly supports the marine propulsion classification before shipment.
