Turbines for marine propulsion
Steam and vapour turbines for marine propulsion
HSN 8406 10 00 (Turbines for marine propulsion) 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 (IEC), bill of entry, commercial invoice, packing list. Other steam and vapour turbines classified elsewhere in Chapter 84 — particularly those for industrial power generation — may attract separate compliance; classification on end-use and design is the principal importer risk.
The absence of compliance at this tariff line does not extend to functionally adjacent machinery: turbines configured for land-based power generation are separately classified within Chapter 84 and may carry distinct obligations, and marine vessels themselves are subject to Directorate General of Shipping approvals that govern installed equipment. Re-classification by customs on examination — for instance, if the declared marine application is disputed — triggers retrospective compliance and potential detention pending resolution. Verify the vessel application, propulsion specification, and end-use documentation before relying on the absence of compliance at this line.
