8501.34 - Of an output exceeding 375 kW:

This HTS category, 8501.34, encompasses DC motors and DC generators that possess a significant power output, specifically exceeding 375 kilowatts (kW). These are high-capacity electrical machines designed for industrial applications, heavy machinery, or large-scale power generation. The defining characteristic for classification within this code is the power rating, differentiating them from smaller or medium-sized electric motors and generators.

To distinguish 8501.34 from its sibling categories, it's crucial to note the power thresholds. Category 8501.31 covers devices not exceeding 750 watts, while 8501.32 applies to those between 750 watts and 75 kW. Category 8501.33 addresses a higher range, from over 75 kW up to 375 kW. Therefore, 8501.34 specifically captures the segment of DC motors and generators with power outputs *greater than* 375 kW, representing the most powerful units within this broader group.

Within 8501.34, further subdivisions exist to differentiate between the function of these high-power machines. Subcategory 8501.34.30.00 is dedicated to DC motors, which convert electrical energy into mechanical energy for driving equipment. Conversely, subcategory 8501.34.61.00 covers DC generators, which perform the opposite function, converting mechanical energy into electrical energy. This distinction is vital for accurate customs reporting and duty assessment.
