8501.32.55.20 - For use in civil aircraft

This HTS classification, 8501.32.55.20, specifically covers DC motors designed for use in civil aircraft. These are electric motors that convert direct current electrical energy into mechanical energy, characterized by their output power range exceeding 750 Watts but not exceeding 75 kilowatts. The defining attribute for this subcategory is their intended application within the aviation industry, implying adherence to rigorous aerospace standards for reliability, performance, and safety.

Distinguishing this category from its sibling, 8501.32.55.40 (also "Other"), lies solely in the specific end-use. While both fall under "Other" DC motors within the specified power range, 8501.32.55.20 is exclusively for civil aircraft applications. This implies that motors classified under the sibling category might be intended for other industrial, commercial, or specialized uses that do not meet the strict criteria for aerospace equipment.

As this is a leaf node, there are no further subcategories. The classification is therefore precise and does not break down further based on motor type, construction, or specific function within an aircraft. The inclusion of "For use in civil aircraft" is the ultimate distinguishing factor, making the classification dependent on the intended aerospace application rather than intrinsic technical variations of the motor itself beyond the established power parameters.
