SITCSection 7
U.S. imports of ac electric motors with output exceeding 37.5 w (SITC 71631) totaled $489.6M in April 2026, traded with 72 countries.
Importers of AC Electric Motors with Output Exceeding 37.5 W paid $51.1M in duties in April 2026 — an effective duty rate of 18% on $280.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataAlternating-current motors above 37.5 W — including single-phase, three-phase induction, and universal AC/DC types — are among the most widely traded electromechanical products globally, serving HVAC systems, industrial pumps, compressors, conveyors, and machine tools. Energy-efficiency regulations, including DOE minimum efficiency standards for general-purpose motors, influence which imported models are admissible for sale in the US market, adding a compliance layer beyond customs classification. Section 301 tariffs have reshaped sourcing patterns for Chinese-origin motors, accelerating qualification of suppliers in Mexico and other regions.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. The US Department of Energy enforces minimum energy efficiency standards for covered motor categories under 10 CFR Part 431. Importers of general-purpose AC motors must ensure their products meet the applicable efficiency level (e.g., NEMA Premium or equivalent IE3) and that the required efficiency data is documented. Non-compliant motors cannot be legally sold or distributed in the US, regardless of their customs clearance status.
A universal motor uses a wound armature and series field windings that allow it to operate on either AC or DC supply, whereas a standard AC induction motor relies on electromagnetic induction and operates only on AC. Both types with output exceeding 37.5 W fall within SITC 71631, but the distinction matters for DOE efficiency program applicability and for matching the motor to its intended power supply in the end-use application.
