U.S. imports of steam and vapor turbines exceeding 40 mw (non-marine) (HS 840681) totaled $800K in April 2026, traded with 5 countries.
Importers of Steam and Vapor Turbines Exceeding 40 MW (Non-Marine) paid $134K in duties in April 2026 — an effective duty rate of 17% on $800K in dutiable value, based on actual customs collections rather than the published tariff schedule. Steam and Vapor Turbines Exceeding 40 MW (Non-Marine) imports of $800K in April 2026 ran 34% above the year-to-date monthly average of $596K.
Last updated: April 2026 dataLarge stationary steam turbines above 40 MW — the workhorses of utility-scale power generation — are classified across three 10-digit lines depending on turbine type: condensing-type steam turbines (8406811020), other steam turbines (8406811070), and non-steam vapor turbines (8406819000). Germany and Israel are the leading US suppliers, consistent with the dominance of European industrial conglomerates in utility turbine manufacturing. These are among the highest-value single-unit imports in the machinery chapters, and their long procurement and installation cycles mean classification and valuation decisions are often made years before physical importation.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A condensing turbine exhausts steam into a condenser operating below atmospheric pressure, maximizing energy extraction — the standard configuration for utility power plants. Non-condensing (back-pressure) turbines exhaust at above-atmospheric pressure for process steam applications. The condensing/non-condensing distinction drives the split between 8406811020 and 8406811070; the turbine's exhaust configuration and design documentation are the key classification evidence.
There are no broad Section 232 or antidumping orders currently targeting large steam turbines from Germany. However, importers should confirm current status with a licensed customs broker, as trade-remedy landscapes evolve. Germany is an EU member, and while the US and EU have no comprehensive FTA, bilateral tariff negotiations and any applicable duty suspension programs should be reviewed for high-value capital equipment entries.
