8501.51.20 - Exceeding 37.5 W but not exceeding 74.6 W

This HTS category, 8501.51.20, specifically covers other AC motors that are multi-phase and designed to produce an output exceeding 37.5 Watts but not exceeding 74.6 Watts. These motors are generally used in industrial or commercial applications where a specific power range is required for operation. The classification is dependent on the continuous rated output power of the motor.

It is crucial to distinguish this category from its siblings. For instance, 8501.51.40 classifies similar multi-phase AC motors but with a broader output range, from exceeding 74.6 Watts up to 735 Watts. Similarly, 8501.51.50 and 8501.51.60 cover different output thresholds and a general "other" category for multi-phase AC motors within the 750W limit but outside the defined wattage bands. This narrower range of 37.5W to 74.6W is the defining characteristic for classification under 8501.51.20.

Within this specific classification, further subdivisions exist to refine the categorization of these motors. The subcategories 8501.51.20.20 for "Gear motors" and 8501.51.20.40 for "Other" allow for more precise identification. Gear motors incorporate a gearbox, impacting their speed and torque characteristics, while the "Other" subcategory would encompass all remaining AC multi-phase motors within the specified wattage range that do not include an integrated gearbox.
