8412.39.00 - Other

This HTS category, 8412.39.00, encompasses pneumatic power engines and motors that are not of the linear-acting type, which are classified under 8412.31.00. Specifically, this subheading covers pneumatic motors and engines designed for rotary motion, where the output shaft rotates continuously rather than moving back and forth in a straight line. These devices harness compressed air to generate rotational force, driving various machinery and equipment across a wide range of industrial applications.

Unlike their linear-acting counterparts which produce reciprocating motion, the pneumatic devices classified here are distinguished by their ability to provide sustained, cyclical rotation. This makes them suitable for tasks such as powering pumps, fans, conveyors, and other rotational equipment where a continuous turning action is required. The mechanism for achieving this rotation can vary, but the defining characteristic is the generation of rotary power from pneumatic pressure.

Within this category, further distinctions are made to provide more granular classification. Subcategories exist to differentiate between unlimited rotary acting engines and motors and other types not otherwise specified. This allows for precise identification based on the specific design and intended operational scope of the pneumatic rotary device, ensuring accurate tariff application.
