U.S. imports of ac electric motors with output exceeding 37.5 w (SITC 71631) totaled $493.5M in July 2026, traded with 83 countries.

Importers of AC Electric Motors with Output Exceeding 37.5 W paid $52.4M in duties in July 2026 — an effective duty rate of 19% on $278.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.

Last updated: July 2026 data

Alternating-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.

Frequently Asked Questions

Do imported AC motors need to meet DOE energy-efficiency standards before they can be sold in the US?

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.

What distinguishes a 'universal' AC/DC motor from a standard AC induction motor for classification under this heading?

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.
