U.S. imports of Steam and Vapor Turbines Exceeding 40 MW (Non-Marine) (HS 840681) totaled $4.4M in August 2026, imported from 7 countries.
Importers of Steam and Vapor Turbines Exceeding 40 MW (Non-Marine) paid $1.9M in duties in August 2026, an average duty rate of 44.09% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Steam and Vapor Turbines Exceeding 40 MW (Non-Marine) imports of $4.4M in August 2026 ran 19% below the year-to-date monthly average of $5.4M.
Last updated: August 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.

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.
