Overview
HTS 8413.50.00.50 specifically classifies diaphragm pumps, a type of reciprocating positive displacement pump. These pumps utilize a flexible diaphragm, actuated by mechanical, hydraulic, or pneumatic force, to displace fluid. Their primary characteristic is the isolation of the pumped medium from the pump's mechanical components by the diaphragm.
This category distinguishes itself from its sibling, 8413.50.00.10, which is reserved for oil well and oil field pumps. While diaphragm pumps may be used in oilfield applications, 8413.50.00.50 serves as the residual classification for all other diaphragm pumps not specifically designated for oil and gas extraction. It covers a broad range of industrial, laboratory, and specialized diaphragm pumps used for various liquid transfer applications where hygienic, corrosive, or abrasive fluid handling is required.
As this is a leaf node, there are no further subcategories. Classification under 8413.50.00.50 is determined by the pump's design featuring a diaphragm as the primary displacement mechanism and its exclusion from the specific oil and gas industry category.
