8412.29.80.60 - Other

This classification, "Other," within the "Unlimited rotary acting" subcategory for hydraulic power engines and motors, serves as a residual category for devices that do not fit into the more specifically defined types. It encompasses hydraulic rotary actuators and motors that convert hydraulic pressure into rotary motion but are not classified as gear, radial piston, or axial piston types. Classification into this category relies on the absence of these specific design features, focusing instead on the general function of providing unlimited rotary output powered by hydraulic fluid.

This category is distinguished from its sibling categories by the absence of the specific mechanical arrangements that define them. "Gear type" motors utilize meshing gears to produce rotation. "Radial piston type" motors employ pistons arranged radially around a central shaft, while "axial piston type" motors have pistons aligned parallel to the output shaft. If an unlimited rotary acting hydraulic power engine or motor does not incorporate these distinct piston or gear configurations for its primary power transmission, it would fall under this "Other" classification.

As a leaf node, this category has no further subdivisions. Therefore, the focus for classification here is on identifying hydraulic rotary devices that perform the function of converting hydraulic energy into rotary motion but do not conform to the specific technical descriptions of the preceding sibling categories. Importers and exporters should carefully examine the design and operating principles of their hydraulic rotary actuators and motors to ensure accurate classification, particularly when the device does not readily fit into a more narrowly defined HTS heading.
