8413.70.20.30 - Single-stage, double-suction

This HTS category, 8413.70.20.30, specifically covers single-stage centrifugal pumps that are designed with a double-suction impeller. A double-suction impeller draws fluid from both sides simultaneously, which is typically employed in pumps requiring higher flow rates and greater efficiency compared to single-suction designs. These pumps are mechanical devices that operate by imparting kinetic energy to a fluid through a rotating impeller, leading to the movement of liquids.

Distinguishing this category from its siblings, "single-stage, double-suction" differentiates it from categories like "single-stage, single-suction" pumps, which only draw fluid from one side of the impeller. It also differs from "multi-stage, single- or double-suction" pumps, which utilize multiple impellers in series to achieve higher discharge pressures. The "other" at this level implies that pumps fitting the single-stage, double-suction description, but not meeting the specific criteria of other enumerated subheadings at this level, fall here.

As this is a leaf node, there are no further subdivisions under 8413.70.20.30. Therefore, the classification hinges entirely on meeting the criteria of being a single-stage centrifugal pump with a double-suction impeller. Examples of goods classified here would include industrial pumps used in water supply, circulation systems, or general fluid transfer applications where substantial flow is required from a single pumping stage, and where the efficiency benefits of a double-suction design are a key characteristic.
