U.S. exports of diesel electric generating sets, 75–375 kva output (HS 850212) totaled $12.5M in July 2026.
Importers of Diesel Electric Generating Sets, 75–375 KVA Output paid $1.0M in duties in July 2026 — an effective duty rate of 14% on $7.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataMid-range diesel generating sets in the 75–375 KVA band are a primary choice for hospitals, data centers, and industrial facilities requiring reliable standby or prime power with proven compression-ignition technology. Brazil leads US import supply for this heading, with the United Kingdom and France also significant sources — reflecting European manufacturers' strong presence in the commercial and industrial genset market. The heading maps to a single 10-digit line, 8502120000. Importers should be aware that complete generating sets — engine, alternator, and control panel assembled on a common base — are classified here rather than as separate components, provided they are presented as a functional unit.

If the engine and alternator are shipped separately and not presented as a complete, assembled generating set, each component is classified under its own HTS heading — the engine under Chapter 84 and the alternator under Chapter 85. Classification as a complete generating set under 850212 requires that the components be presented together as a functional unit. Importers planning split shipments should consult a customs broker to assess classification and any duty implications.
The manufacturer's nameplate rating and technical datasheet showing rated output in KVA are the primary supporting documents. For units near the 75 KVA or 375 KVA thresholds, CBP may request factory test certificates or engineering specifications. Prime power and standby power ratings often differ; classification is based on the rated maximum continuous output, so importers should confirm which rating applies under the applicable HTS rules.
