8413.50.00.90 - Other 🖩

This classification, HTS 8413.50.00.90, encompasses "Other" reciprocating positive displacement pumps. These are pumps that operate by trapping a fixed amount of fluid and forcing (displacing) that trapped volume into the discharge pipe. They are distinct from other pumps in that they utilize a reciprocating motion of a piston, plunger, or diaphragm to achieve this displacement. This category is specifically for those reciprocating pumps not otherwise classified within more granular subheadings.

The key differentiator for this category lies in its "catch-all" nature for reciprocating positive displacement pumps that do not fit into more specific descriptions. For instance, while pumps designed specifically for hydraulic power transmission might share some operational similarities, they are classified separately under sibling categories, such as HTS 8413.50.00.30 for "Hydraulic fluid power pumps." This means that if a reciprocating pump's primary function is not for hydraulic systems, and it doesn't have any other defining characteristic that would place it in a more specific subheading, it will fall under this "Other" category.

As this is a leaf node within the HTS structure, there are no further subdivisions (subcategories) for this particular classification. Therefore, classification decisions for goods falling under 8413.50.00.90 will rely on meticulously examining the pump's specific design, intended use, and ensuring it does not meet the criteria for any other more specific pump classifications within Chapter 84. The absence of subcategories emphasizes the need for careful consideration of all relevant classification notes and the overall scope of heading 8413.
