8413.70.20 - Other

This category, HTS 8413.70.20, encompasses centrifugal pumps that do not fit into the specific subcategory of stock pumps used with machinery for producing cellulosic pulp, paper, or paperboard (HTS 8413.70.10). It acts as a residual category for a wide array of centrifugal pumps not otherwise specified, including those designed for various industrial, commercial, and domestic applications. The key defining characteristic remains their centrifugal operating principle, where impellers impart kinetic energy to a fluid, which is then converted to pressure energy.

Unlike the narrowly defined stock pumps, this "Other" category covers a broad spectrum of centrifugal pump designs. This includes, but is not limited to, pumps for water circulation in heating and cooling systems, pumps used in chemical processing, irrigation pumps, and pumps found in household appliances such as washing machines and dishwashers. The distinguishing factor from its sibling category is the absence of the specific functional requirement of being imported for use with paper-making machinery.

This broad category is further subdivided to provide more specific classifications. Within HTS 8413.70.20, you will find the subcategory for submersible pumps (HTS 8413.70.20.04), which are designed to operate fully submerged in the fluid they are pumping. The remaining "Other" subcategories under this code will capture the diverse range of centrifugal pumps that are not submersible, allowing for more granular tariff treatment based on their specific type and application.
