8412.80.10.00 - Spring-operated and weight-operated motors

HTS Code 8412.80.10.00 specifically classifies spring-operated and weight-operated motors. These are power-generating mechanisms that utilize stored energy from a wound spring or the gravitational potential energy of a raised weight to produce rotational or linear motion. Examples include clock mechanisms powered by springs, or simple toys that operate using a wound spring.

This category is distinguished from its sibling category, 8412.80.90.00, which covers "Other" engines and motors. While 8412.80.10.00 is narrowly defined by its reliance on spring or weight power, the "Other" category encompasses any engines and motors not elsewhere specified within heading 8412 that do not operate on a spring or weight mechanism. This distinction is crucial for accurate classification, ensuring that only motors deriving their motive force from these specific energy sources are included here.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification hinges on the precise determination of whether a motor's primary source of motive power is a spring or a weight. Understanding the operational principle of the motor is paramount for correct assignment to this specific sub-heading.
