8413.60.00.20 - Vane type

This HTS category, 8413.60.00.20, specifically covers vane type rotary positive displacement pumps. These pumps are characterized by the use of vanes, typically sliding within a rotor or cam, to displace fluid. They are commonly employed in hydraulic systems for transferring liquids, generating pressure, and controlling flow. The design of vane pumps often allows for high efficiency and relatively quiet operation, making them suitable for a range of industrial applications.

Distinguishing this category from its siblings, 8413.60.00.30 (Gear type) and 8413.60.00.40 (Other), is crucial. While all fall under "Other rotary positive displacement pumps" and are intended for hydraulic fluid power, the defining characteristic here is the *vane mechanism*. Gear type pumps, in contrast, utilize meshing gears to create pockets for fluid displacement. The "Other" category encompasses any remaining rotary positive displacement pumps that do not fit the specific definitions of vane or gear types.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the classification hinges on accurately identifying the pump's operational mechanism as being of the vane type. This means that pumps utilizing other displacement methods, such as screw or lobe designs, would be classified under the "Other" category (8413.60.00.40), provided they are not gear pumps.
