HS Code 8501.51 – Electric motors; AC motors, multi-phase, of an output not exceeding 750W
HS code 8501.51 is the 6-digit subheading for electric motors, AC motors, multi-phase, of an output not exceeding 750W. It is used for small servo motors, stepper motors, small industrial fan motors, light-duty conveyor belt motors and robotics joint motors.
What HS 8501.51 covers
This category includes small multi-phase AC electric motors with an output not exceeding 750W. These motors are crucial for light industrial applications, automation systems, and specialized machinery where precise control, higher efficiency, and robustness are required, even at low power. They are vital components in robotics, small conveyors, textile machinery, and various manufacturing processes. International trade is characterized by a global supply chain for industrial automation and machinery components. Importers are often countries with growing manufacturing sectors and a demand for advanced automation, while exporters are nations with sophisticated electrical component and automation technology. Energy efficiency and compact design are critical factors in their trade.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
