8501.53.80 - Other

HTS Code 8501.53.80 serves as a residual category for multi-phase AC motors of an output exceeding 75 kW, when they do not fall into more specific kilowatt ranges defined by sibling categories. This code captures AC motors that are not precisely defined by the narrower output ranges such as "exceeding 75 kW but under 149.2 kW" (8501.53.40) or "149.2 kW or more but not exceeding 150 kW" (8501.53.60.00). Essentially, it encompasses any AC motor within the broader "exceeding 75 kW" group that falls outside these specifically delineated power output thresholds.

The necessity for this "Other" classification arises from the practical challenges in precisely measuring and cataloging all possible power output permutations for high-capacity industrial motors. It ensures that all qualifying multi-phase AC motors, even those with outputs that don't neatly align with the more granular sibling categories, are assigned to an appropriate classification within the HTS.

This category is further subdivided to provide more refined distinctions based on specific power output ranges. The subcategory 8501.53.80.40 covers motors with an output not exceeding 373 kW, while 8501.53.80.60, also designated as "Other," captures motors with outputs exceeding 373 kW that do not meet the criteria for even more specialized classifications if they existed. These subcategories allow for more precise tariff application based on the specific power rating of the motor.
