8501.33 - Of an output exceeding 75 kW but not exceeding 375 kW:

This HTS classification covers DC motors and DC generators, excluding photovoltaic generators, specifically those with an electrical output power ranging from greater than 75 kilowatts (kW) up to and including 375 kilowatts (kW). These are typically industrial-grade machines used in applications requiring substantial power, such as driving large pumps, compressors, conveyors, or as main drives in manufacturing equipment. The key distinguishing factor for this category is its specified power output range, setting it apart from smaller or larger capacity motors and generators.

In contrast to its sibling categories, 8501.31 covers DC motors and generators with an output not exceeding 750 watts (W), while 8501.32 encompasses those with an output exceeding 750 W but not exceeding 75 kW. Conversely, 8501.34 is reserved for DC motors and generators with an output exceeding 375 kW. Therefore, the classification under 8501.33 is strictly determined by meeting the defined power threshold.

Within this category, further distinctions are made to classify specific types of electrical machinery. Subcategories exist for motors, which are designed to convert electrical energy into mechanical energy, and generators, which perform the opposite function of converting mechanical energy into electrical energy. This granular breakdown facilitates precise classification based on the primary function and application of the electrical machine.
