8501.40.40 - Of an output exceeding 74.6 W but not exceeding 735 W

This HTS category, 8501.40.40, specifically classifies AC (alternating current) single-phase electric motors with an output power ranging from greater than 74.6 Watts up to and including 735 Watts. These motors are designed for a variety of applications where a moderate level of power is required and a single-phase power supply is utilized. They are distinct from other AC single-phase motors based on their precise power output rating.

Distinguishing this category from its siblings, 8501.40.20 covers motors with a lower output range (exceeding 37.5 W but not exceeding 74.6 W), while 8501.40.50 addresses motors with a slightly higher but still defined range (exceeding 735 W but under 746 W). The sibling category 8501.40.60 serves as a residual category for other AC single-phase motors not meeting the specific power output criteria of the other subheadings.

Within this specific power range, further distinctions are made at the subcategory level. 8501.40.40.20 covers gear motors, which are integrated units combining a motor with a gear reduction system to achieve specific torque and speed outputs. The remaining motors falling within the 74.6 W to 735 W power bracket, which are not gear motors, are classified under the residual subheading 8501.40.40.40.
