8501.40.60.40 - Other

This HTS category, 8501.40.60.40, covers "Other" AC motors that are single-phase and not otherwise specified. This classification serves as a residual category for single-phase AC motors that do not fit into more specific subheadings within the broader chapter on electrical machinery. These motors are typically designed for applications where a single alternating current phase is supplied, and they encompass a wide range of sizes, power outputs, and functionalities not explicitly detailed elsewhere.

The key distinction of this category from its sibling, 8501.40.60.20 (Gear motors), lies in the absence of an integrated gear reduction mechanism. While gear motors are specifically designed to reduce rotational speed and increase torque through a gearbox, the motors classified under 8501.40.60.40 are standalone AC motors without this integrated feature. Therefore, if a single-phase AC motor lacks a built-in gearbox, it would likely fall under this "Other" classification.

As this is a leaf node in the HTS classification structure, there are no further subcategories to introduce. The classification of a motor under 8501.40.60.40 hinges on it being a single-phase AC motor that does not meet the specific criteria of any preceding or parallel subheading. Practical classification often involves examining technical specifications, intended use, and the absence of distinguishing features of other, more narrowly defined motor types.
