8413.60.00.40 - Other

This HTS category, 8413.60.00.40, encompasses hydraulic fluid power pumps that do not fall under the specific classifications of vane type (8413.60.00.20) or gear type (8413.60.00.30). Essentially, it serves as a residual category for other types of positive displacement rotary hydraulic pumps. These pumps are designed to impart fluid power through the displacement of a fixed volume of fluid with each rotation, and they are utilized in a wide array of hydraulic systems for applications requiring controlled fluid delivery.

The key distinction of this category lies in its exclusion of more specifically defined rotary hydraulic pump designs. While vane and gear pumps rely on specific internal mechanisms involving rotating vanes or intermeshing gears to achieve fluid displacement, this "Other" category captures all other rotary positive displacement designs. This might include, but is not limited to, piston pumps (axial or radial), screw pumps, or other specialized rotary designs that do not fit the description of vane or gear types, provided they meet the general criteria for hydraulic fluid power pumps.

As a leaf node, this category has no further subdivisions. Therefore, the focus for classification under 8413.60.00.40 is on the definitive identification of the pump as a rotary positive displacement hydraulic fluid power pump, while carefully ensuring it does not meet the specific characteristics of the sibling categories for vane or gear pumps. Classification will rely on the technical specifications and design of the pump mechanism itself.
