U.S. imports of electric generating sets (other than wind, reciprocating engine, or spark-ignition) (HS 850239) totaled $44.8M in April 2026, traded with 26 countries.
Importers of Electric Generating Sets (Other Than Wind, Reciprocating Engine, or Spark-Ignition) paid $3.4M in duties in April 2026 — an effective duty rate of 13% on $26.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataGas turbine, steam turbine, and other non-reciprocating electric generating sets fall under this residual heading, which captures large-scale stationary power generation equipment not classified elsewhere in heading 8502. The US schedule breaks these out into gas-turbine-powered sets (8502390010), steam-turbine-powered sets (8502390040), and two residual lines (8502390080 and 8502390090) that catch remaining configurations. Hungary leads US import supply for this heading, followed by Canada and Mexico, reflecting European and North American industrial manufacturing capacity for heavy power generation equipment. Importers should verify whether specific units are subject to Section 301 tariffs based on origin, as classification between the turbine-specific and residual lines depends on the prime mover type.

The key classification factor is the prime mover type. Gas-turbine-powered sets go under 8502390010, steam-turbine-powered sets under 8502390040, and units driven by other prime movers (such as hydraulic turbines or fuel cells) fall into the residual lines 8502390080 or 8502390090. Consult a licensed customs broker if the prime mover is hybrid or unconventional.
Generating sets from certain origins may be subject to Section 301 tariffs or other trade-remedy measures depending on country of origin and specific product configuration. Hungary, Canada, and Mexico are the leading suppliers to the US under this heading; Canadian and Mexican goods may receive preferential treatment under USMCA, but European-origin equipment should be reviewed for applicable duties at the time of entry.
