SITCSection 7
U.S. exports of steam and other vapor turbines for marine propulsion (SITC 71211) totaled $164K in July 2026.
Importers of Steam and Other Vapor Turbines for Marine Propulsion paid $12K in duties in July 2026 — an effective duty rate of 10% on $121K in dutiable value, based on actual customs collections rather than the published tariff schedule. Steam and Other Vapor Turbines for Marine Propulsion imports of $121K in July 2026 ran 68% below the year-to-date monthly average of $374K.
Last updated: July 2026 dataMarine propulsion steam turbines—used in naval vessels, LNG carriers, and certain commercial ships—represent a specialized segment of the broader turbine market, distinguished by their salt-air-resistant materials, compact footprint, and classification separate from land-based power generation turbines. The marine application drives stringent classification requirements, as the end-use must be demonstrably propulsion rather than auxiliary shipboard power generation. Importers should be prepared to provide vessel specifications and turbine installation drawings to support the marine propulsion classification.

CBP looks for technical documentation showing the turbine is connected to the vessel's propulsion shaft system rather than to an electrical generator. Relevant documents include the turbine's technical specification sheet, the vessel's general arrangement drawing, and the purchase contract specifying the propulsion application.
Marine propulsion steam turbines are not broadly subject to the same Section 301 or antidumping measures that affect many manufactured goods, but importers should verify the current status of any applicable orders for the specific country of origin at the time of entry, as trade-remedy coverage can change. Consulting a licensed customs broker before finalizing supplier contracts is advisable.
