8413.70.20.25 - With discharge outlet 7.6 cm or over in diameter

This HTS category, 8413.70.20.25, specifically classifies centrifugal pumps that are single-stage, single-suction, and frame-mounted, and possess a discharge outlet with a diameter of 7.6 centimeters or greater. These pumps are designed for moving liquids and are characterized by their construction where the impeller rotates within a volute casing to impart kinetic energy to the liquid, which is then converted to pressure energy. The frame-mounting indicates a configuration where the pump and its driver (such as an electric motor or engine) are mounted on a common base frame.

The key differentiating factor for this classification, as indicated by its sibling category, 8413.70.20.22, lies solely in the size of the discharge outlet. While both are single-stage, single-suction, frame-mounted centrifugal pumps, this specific code applies when the discharge outlet measures 7.6 cm or more in diameter. The sibling category covers pumps with a discharge outlet of less than 7.6 cm. Therefore, accurate measurement of the discharge outlet diameter is crucial for correct classification.

As this is a leaf node in the HTS classification system, there are no further subcategories. Classification under 8413.70.20.25 is final based on the described characteristics: being a centrifugal pump, single-stage, single-suction, frame-mounted, and having a discharge outlet of 7.6 cm or more in diameter. Examples of pumps fitting this description might include those used in industrial water circulation, large-scale irrigation systems, or dewatering operations where higher flow rates and pressures are required.
