U.S. imports of diesel electric generating sets, output not exceeding 75 kva (HS 850211) totaled $22.6M in April 2026, traded with 19 countries.
Importers of Diesel Electric Generating Sets, Output Not Exceeding 75 KVA paid $2.1M in duties in April 2026 — an effective duty rate of 12% on $17.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Diesel Electric Generating Sets, Output Not Exceeding 75 KVA imports of $22.6M in April 2026 ran 28% above the year-to-date monthly average of $17.7M.
Last updated: April 2026 dataCompact diesel generating sets rated at 75 KVA or below serve construction sites, small commercial facilities, and emergency backup applications where portability and fuel availability in remote locations are priorities. Japan leads US import supply for this heading — reflecting the dominance of Japanese engine manufacturers in the small diesel genset segment — with Canada and the Dominican Republic also among the top sources. The heading resolves to a single 10-digit line, 8502110000, so classification disputes typically arise from the boundary with spark-ignition (gasoline) generating sets under 850220 rather than from internal line selection. Engine type — compression-ignition versus spark-ignition — is the controlling classification criterion.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The distinction is based on engine type: compression-ignition (diesel or semi-diesel) engines classify under 850211, while spark-ignition engines classify under 850220. Dual-fuel or bi-fuel units require analysis of the primary ignition method. Importers should provide engine technical specifications confirming ignition type, as misclassification between these headings can affect duty rates and any applicable trade-remedy exposure.
Yes. Diesel engines used in nonroad applications — including most portable and stationary generating sets — must comply with EPA nonroad diesel emission standards (Tier 4 for most new equipment). Importers must ensure the engine meets the applicable EPA tier certification for the intended use and power rating. Noncompliant engines may be refused entry or require costly modifications.
