U.S. imports of multi-phase ac motors, output not exceeding 750 w (HS 850151) totaled $54.5M in April 2026, traded with 55 countries.
Importers of Multi-Phase AC Motors, Output Not Exceeding 750 W paid $5.5M in duties in April 2026 — an effective duty rate of 15% on $37.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Multi-Phase AC Motors, Output Not Exceeding 750 W imports of $54.5M in April 2026 ran 11% above the year-to-date monthly average of $49.3M.
Last updated: April 2026 dataSmall multi-phase (typically three-phase) AC motors rated up to 750 W are widely used in precision industrial equipment, robotics, and conveyor systems where polyphase power is available and smooth torque delivery at low wattages is required. Like their single-phase counterparts, the US schedule pairs gear motor lines with general NESOI lines at each output band, spanning ten 10-digit tariff lines from 8501512020 through 8501516040. Mexico leads imports, followed by Japan and Germany — the latter two reflecting the precision engineering heritage of their motor industries.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No. Heading 850151 covers outputs not exceeding 750 W, but the highest 10-digit line (8501516040) covers motors greater than 746 W but less than or equal to 750 W. A motor with a nameplate rating of exactly 750 W would fall within this line. Motors exceeding 750 W move to heading 850152. Nameplate documentation is essential for motors near this boundary.
When a motor is imported as a component of a complete machine, it may be classifiable with the machine rather than separately under heading 8501, depending on whether it is presented as a standalone unit or integrated into the finished assembly. CBP's rules on composite goods and GRI 2(a) govern this analysis. Importers should assess whether the motor retains its own identity or is subsumed into the machine's classification.
