8501.33.20.40 - For use in civil aircraft

This classification pertains to DC motors with an electrical output exceeding 75 kilowatts (kW) but not exceeding 375 kW, specifically designed for installation and operation within civil aircraft. These motors are essential components in various aircraft systems, powering functions such as actuation, ventilation, or other specialized applications where high power output is required and the environment necessitates aircraft-grade components. The "For use in civil aircraft" designation is a critical determining factor, indicating that the motor's design, testing, and certifications meet stringent aviation standards.

This category is distinct from its sibling, 8501.33.20.80 ("Other"), which would encompass DC motors within the same power range (exceeding 75 kW but not exceeding 375 kW) that are not specifically designated for civil aircraft use. The primary differentiator lies in the intended application and the associated regulatory and performance requirements inherent to aerospace components.

As this is a leaf node within the HTS classification system, there are no further subcategories for this specific code. Therefore, the classification is precisely defined by the power output range and the explicit requirement of being for use in civil aircraft.
