Of an output exceeding 40 MW
Steam turbines and other vapour turbines, output exceeding 40 MW
HSN 8406 81 00 (steam turbines and other vapour turbines of an output exceeding 40 MW) 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 turbine classifications within Chapter 84 — including turbines of 40 MW or below, or parts thereof — may carry distinct compliance; correct output-rating documentation is the principal classification risk.
The absence of compliance at this tariff line applies specifically to complete steam and vapour turbines rated above 40 MW; turbines at or below that output threshold are separately classified and may attract different treatment on customs examination. Parts and components of steam turbines fall under a further distinct tariff line within Chapter 84 and warrant independent classification review. A re-classification by customs — based on rated output, completeness of the assembly, or intended use — triggers retrospective compliance, including detention pending resolution.
