8501.53.40 - Exceeding 75 kW but under 149.2 kW

This HTS category, 8501.53.40, encompasses multi-phase AC motors specifically designed to have an electrical output exceeding 75 kilowatts (kW) but remaining under 149.2 kW. These motors are typically industrial-grade and used in applications requiring significant power, such as in manufacturing plants, heavy machinery, or large-scale pumping systems, where precise power output is a key differentiating factor.

This classification distinguishes itself from its siblings by its specific power output range. Category 8501.53.60.00 covers motors with a slightly higher power output, specifically those rated at 149.2 kW or more but not exceeding 150 kW, while category 8501.53.80 serves as a catch-all for other multi-phase AC motors exceeding 75 kW that do not fit within the more specific power ranges. The precise kilowatt rating is the primary determinant for correct classification within these sibling categories.

Further refinement within this category is provided by its subcategories, which segregate motors based on their intended application. Category 8501.53.40.40 is reserved for those motors specifically designated for use in civil aircraft, reflecting specialized design and stringent certification requirements. The subcategory 8501.53.40.80, "Other," captures all remaining multi-phase AC motors within this 75 kW to under 149.2 kW power range that are not intended for civil aviation.
