8501.51 - Of an output not exceeding 750 W:

This HTS category, 8501.51, specifically encompasses AC multi-phase electric motors whose continuous output power does not exceed 750 Watts. These motors are designed for operation with alternating current and are characterized by having more than one phase winding, distinguishing them from single-phase AC motors. Their applications are diverse, typically found in smaller machinery and equipment where moderate power is required, such as in household appliances, small industrial tools, pumps, and fans.

It is crucial to differentiate this category from its sibling categories at the same level. HTS 8501.52 covers AC multi-phase motors with a higher power output, specifically exceeding 750 W but not exceeding 75 kW. Further up the power scale, HTS 8501.53 includes those with an output exceeding 75 kW. Therefore, the defining characteristic for classification within 8501.51 is strictly the output power limit of 750 W.

Within the 8501.51 category, further subdivisions exist to provide more granular classification based on precise power output ranges. These subcategories, such as 8501.51.20 (exceeding 37.5 W but not exceeding 74.6 W) and 8501.51.40 (exceeding 74.6 W but not exceeding 735 W), allow for a more detailed tariff assignment for motors within the 750 W overall limit. The existence of these subcategories highlights the importance of accurate power rating specifications for proper customs declaration.
