U.S. imports of Motors & Generators (NAICS 335312) totaled $2.0B in August 2026, imported from 110 countries.
Importers of Motors & Generators paid $214.3M in duties in August 2026, an average duty rate of 10.76% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataElectric motors and generators serve as foundational components across manufacturing, HVAC, transportation electrification, and power generation, making this NAICS category a high-volume segment of industrial trade. Section 301 tariffs have been applied to a broad range of motors and generators imported from China, and antidumping proceedings have historically targeted certain motor types, creating a layered duty environment that requires careful classification. Output ratings — measured in horsepower or kilowatts — are the primary variable driving HTS subheading assignment, and small differences in rated output can shift a product into a different duty bracket. Importers sourcing across multiple motor sizes should conduct a line-by-line classification review to accurately model landed cost.

HTS headings for electric motors are broken into subheadings based on output thresholds — typically expressed in watts or horsepower — with distinct duty rates at each tier. Importers must use the motor's rated output as specified on the nameplate or technical documentation to determine the correct subheading; using nominal or approximate values can result in misclassification.
Yes, certain electric motor categories — including small AC motors — have been subject to antidumping duty orders from specific countries of origin. These orders are cumulative with Section 301 tariffs where both apply, significantly increasing landed cost. Importers should check active Commerce Department antidumping orders for their specific motor type and origin before sourcing.
