8501.10.20.00 - Synchronous, valued not over $4 each

This HTS category, 8501.10.20.00, specifically classifies synchronous electric motors with an output not exceeding 37.5 watts, where the individual motor's value is $4 or less. These are typically small, low-power motors used in a wide array of consumer electronics, appliances, and small mechanical devices where precise speed control is required, such as in small fans, timing mechanisms, and certain types of actuators. The synchronous nature means these motors operate at a speed directly proportional to the frequency of the applied alternating current.

This category is distinguished from its sibling, 8501.10.40 ("Other"), which encompasses synchronous motors of an output not exceeding 37.5 watts that do not meet the value criterion of $4 or less each. Therefore, the primary differentiator here is the unit value of the motor. Motors classified under 8501.10.20.00 are intended for high-volume, cost-sensitive applications, whereas those under 8501.10.40 may be used in applications where a higher unit cost is acceptable for potentially greater power, specific features, or higher quality.

As this is a leaf node within the HTS, there are no further subcategories. Classification under this specific code is determined by the combined criteria of being a synchronous motor, having an output not exceeding 37.5 W, and a value of $4 or less per unit. The focus for classification professionals lies in verifying these two key attributes: the motor's operating principle (synchronous) and its stated value per unit.
