8413.40.00.00 - Concrete pumps

This HTS subheading specifically classifies concrete pumps. These are machines designed and equipped to transport and dispense concrete, typically via a hose or boom system. Their primary function involves the pressurized movement of viscous concrete mixtures from a mixer or source to a desired pour location on a construction site.

Distinguishing concrete pumps from their siblings, this category is distinct from hand pumps (8413.20) or pumps specifically designed for fuel, lubricating, or cooling systems of internal combustion engines (8413.30). It also differs from other positive displacement pumps (reciprocating in 8413.50 and rotary in 8413.60) that, while they move fluid, are not specialized for the high-pressure, high-volume delivery of concrete. The defining characteristic is the engineered capability to handle and pump concrete.

As a leaf node, subheading 8413.40.00.00 does not have further subdivisions. Therefore, classification within this subheading relies on the clear identification of the machinery as a concrete pump, based on its design, function, and intended use in construction and infrastructure projects. The presence of features like robust pumping mechanisms, specialized delivery hoses or booms, and controls for managing concrete flow are key indicators for correct classification here.
