8413.70.20.15 - With discharge outlet 5.08 cm or over in diameter

This HTS classification, 8413.70.20.15, covers centrifugal pumps designed for liquids that possess a specific physical characteristic: a discharge outlet measuring 5.08 centimeters (2 inches) or greater in diameter. These are typically more robust pumps intended for higher flow rates or larger volumes of liquid. The pumps classified here are further distinguished by their configuration as single-stage, single-suction, and close-coupled units, meaning they operate with a single impeller, draw fluid from one side, and have the motor directly coupled to the pump shaft, often eliminating the need for a separate base or coupling.

The key differentiator for this category at this level of detail lies precisely in the diameter of the discharge outlet. It is explicitly separated from its sibling category, 8413.70.20.05, which covers identical pumps but with a discharge outlet diameter *under* 5.08 centimeters. Therefore, the precise measurement of this specific outlet dimension is the determining factor for correct classification between these two closely related subheadings.

As this is a leaf node within the HTS database, there are no further subcategories branching from 8413.70.20.15. Classification at this point is definitive based on the pump's type (centrifugal), stage and suction configuration (single-stage, single-suction, close-coupled), and the specified discharge outlet diameter of 5.08 cm or greater. Examples of applications might include industrial water transfer, municipal sewage pumps, or large-scale agricultural irrigation systems where significant liquid movement is required.
