U.S. imports of Spark-Ignition (Gasoline) Electric Generating Sets (HS 850220) totaled $350.5M in August 2026, imported from 23 countries.
Importers of Spark-Ignition (Gasoline) Electric Generating Sets paid $16.6M in duties in August 2026, an average duty rate of 4.74% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Spark-Ignition (Gasoline) Electric Generating Sets imports of $350.5M in August 2026 ran 108% above the year-to-date monthly average of $168.3M.
Last updated: August 2026 dataGasoline-powered generating sets — ranging from sub-1.5 KW portable units to sets exceeding 75 KVA — are classified under 850220, with the US schedule subdividing the heading into six 10-digit lines by output level and application. Vietnam leads US import supply, with Austria and China also prominent; Chinese-origin goods may be subject to Section 301 tariffs, a significant cost factor given China's historical dominance in the portable consumer genset segment. The wide output range within this heading means that a backyard portable generator and a large standby gasoline genset share the same HS6 code but land in different 10-digit lines, making accurate wattage documentation essential. EPA nonroad spark-ignition engine emission standards apply to most imported units.

Small portable consumer generators — typically in the 1–5 KW range — generally fall under 8502200030 (under 1.5 KW), 8502200060 (1.5 KW to 5 KW), or 8502200040 (under 5 KVA, for units meeting that description). Importers should match the generator's rated output precisely to the applicable line, as duty rates and Section 301 applicability can differ across lines within the same heading.
Spark-ignition nonroad engines in generating sets must comply with EPA Small Spark-Ignition (SI) or Large SI nonroad engine emission standards, depending on displacement. Importers must ensure the engine holds a valid EPA certificate of conformity for the applicable model year and engine family. EPA Form 3520-21 is required at entry for nonroad engines. Noncompliant engines cannot be legally sold or operated in the US and may be subject to seizure or re-export.
