8501.53.80.40 - Not exceeding 373 kW

This HTS category, 8501.53.80.40, specifically encompasses AC motors that are multi-phase, have an output exceeding 75 kW, and are further categorized as "other" within this sub-heading. These motors are characterized by their substantial power output, making them suitable for industrial applications requiring significant torque and continuous operation. Examples include large-scale motors used in manufacturing equipment, pumps, compressors, and heavy machinery where high performance is essential. The classification hinges on the motor's AC multi-phase nature, its power rating exceeding the 75 kW threshold, and its exclusion from more specific sub-classifications that might exist at a more granular level.

The distinction between this category and its sibling, 8501.53.80.60, also labeled as "Other," lies in the underlying HTS structure. While both are designated as "Other" within the broader "Of an output exceeding 75 kW" sub-heading for multi-phase AC motors, the specific numerical designation (80.40 vs. 80.60) indicates a further, albeit unstated at this level, differentiation in the HTS database. This often relates to minute distinctions in design, application, or historical classification practices that are not immediately apparent from the general description. Importers and exporters should consult detailed HTS annotations or customs rulings for absolute clarity on the precise criteria separating these two "Other" designations.

As a leaf node in the HTS classification, this category does not have further subcategories. Therefore, the focus for classification purposes remains on ensuring the motor meets all the preceding criteria: it must be an AC motor, multi-phase, with an output power exceeding 75 kW, and it must not fall under any more specific classification that might exist at a higher level of detail within the HTS. The "Not exceeding 373 kW" description acts as a crucial upper limit for this specific code, differentiating it from even larger motors that would be classified under different HTS codes.
