8501.40.40.20 - Gear motors

This HTS classification, 8501.40.40.20, specifically covers gear motors. A gear motor is an electric motor that is combined with a gear reduction system. The primary function of the gear reduction is to decrease the rotational speed of the motor while simultaneously increasing its torque. This combination is essential for applications requiring high torque at low speeds, such as conveyor systems, automated machinery, and industrial equipment.

Within the broader category of "Other AC motors, single-phase: Of an output exceeding 74.6 W but not exceeding 735 W," this subcategory distinguishes itself from its sibling, 8501.40.40.40, which is designated for "Other" AC single-phase motors within the same power range that do not fall under the specific definition of gear motors. Therefore, if an AC single-phase motor within this wattage range incorporates a gear reduction mechanism, it will be classified under 8501.40.40.20, whereas a motor without this integrated gearing would fall into the "Other" category.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Classification decisions at this level will rely on accurately identifying the presence and function of the integrated gear reduction system and ensuring the motor's electrical characteristics (AC, single-phase) and power output fall within the specified range of 74.6 W to 735 W, aligning with the broader scope of its parent categories.
