8412.29 - Other:

HTS code 8412.29 encompasses hydraulic power engines and motors that are not of the linear-acting (cylinder) type, which are classified under 8412.21. This category specifically includes rotary hydraulic motors, which convert hydraulic pressure into rotational mechanical power. These devices are essential components in a wide array of industrial machinery and equipment where precise and powerful rotary motion is required, such as in construction vehicles, manufacturing equipment, and agricultural machinery.

The key differentiator for items within 8412.29 is their rotary output mechanism, distinguishing them from the linear (piston-driven) motion of hydraulic cylinders. While both types utilize hydraulic fluid to generate power, their fundamental operational output is different. Therefore, when classifying hydraulic power engines and motors, it is crucial to identify whether the primary output is a linear stroke or a rotational torque.

Within HTS 8412.29, further subclassification exists to provide more granular detail. Items such as hydrojet engines for marine propulsion are specifically identified under 8412.29.40.00, recognizing their specialized application. All other rotary hydraulic power engines and motors that do not fall into these specific subcategories are classified under the residual category 8412.29.80, ensuring comprehensive coverage for this group of machinery.
