8501.53 - Of an output exceeding 75 kW:

This HTS category, 8501.53, encompasses multi-phase alternating current (AC) electric motors that have an output power exceeding 75 kilowatts (kW). These are industrial-grade motors designed for heavy-duty applications where significant power is required to drive machinery. Examples include large pumps, industrial fans, compressors, crushers, and main drives for manufacturing equipment.

Distinguishing this category from its siblings, 8501.51 covers motors with outputs not exceeding 750 watts (W), and 8501.52 includes motors with outputs greater than 750 W but not exceeding 75 kW. Therefore, 8501.53 is specifically for the most powerful AC multi-phase motors within the 8501.5 series, handling applications demanding substantial torque and continuous operation.

Within 8501.53, further subcategories exist to refine classification based on precise power output ranges. These include specific subdivisions for motors exceeding 75 kW but under 149.2 kW (8501.53.40), those rated at 149.2 kW or more but not exceeding 150 kW (8501.53.60.00), and a residual category for all other motors exceeding 75 kW that do not fall into the more specific ranges (8501.53.80). This hierarchical structure allows for granular tariff application according to the motor's power rating.
