8501.20 - Universal AC/DC motors of an output exceeding 37.5 W:

This HTS category, 8501.20, specifically encompasses universal AC/DC motors designed with an output exceeding 37.5 Watts. Universal motors are characterized by their ability to operate on either alternating current (AC) or direct current (DC) power sources, a key differentiator from other motor types. These motors are commonly found in applications requiring higher power and torque, such as power tools, vacuum cleaners, and industrial equipment.

Distinguishing 8501.20 from its sibling categories is crucial for accurate classification. Motors with an output *not exceeding* 37.5 W fall under 8501.10. Other categories within 8501 cover specific types of AC motors (single-phase or multi-phase), DC motors, and AC generators, each defined by their operating current, phase, and design. The defining factor for this particular node is the combination of universal AC/DC functionality and an output power greater than 37.5 Watts.

To further refine classification, HTS code 8501.20 is further subdivided based on the precise power output of the universal motor. The subcategories (e.g., 8501.20.20.00, 8501.20.40.00, 8501.20.50.00) provide specific power ranges, allowing for a granular approach to tariff classification. An "Other" subcategory exists to capture any universal AC/DC motors exceeding 37.5 W that do not fall within the defined power output ranges.
