U.S. imports of Turbines & Turbine Generator Sets (NAICS 333611) totaled $736.0M in August 2026, imported from 68 countries.
Importers of Turbines & Turbine Generator Sets paid $82.9M in duties in August 2026, an average duty rate of 11.42% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataGas, steam, and hydraulic turbine generator sets are long-lead capital goods central to utility-scale power generation, LNG processing, and industrial cogeneration projects. Imported turbine generator sets are classified under Chapter 84 of the HTS, with the applicable subheading driven by the turbine's motive fluid (steam, gas, water) and output capacity — distinctions that also affect whether Section 301 or other trade-remedy measures apply. Given multi-year project timelines and the specialized nature of OEM supply chains, procurement teams should confirm HTS classification and duty exposure well before contract award.

Steam turbines, gas turbines, and hydraulic turbines each fall under distinct HTS headings within Chapter 84, and output capacity thresholds can further subdivide classification. The duty rate and any applicable trade-remedy exposure differ by subheading, so a detailed technical specification review is essential before filing an entry.
Beyond standard commercial invoice and packing list requirements, importers of large turbine sets often need detailed engineering specifications to support HTS classification, a certificate of origin, and — for certain origins — documentation to claim or rebut trade-remedy applicability. Oversized or heavy-lift shipments may also require special permits and advance coordination with the port of entry.
