HS Code for Liquid pump

HS code 8413.82 is specifically designated for "liquid elevators," which are a unique subset of liquid-moving machinery. While most liquid pumps are classified under subheadings 8413.11 through 8413.81 based on their mechanical action (such as centrifugal, reciprocating, or rotary), liquid elevators utilize different physical principles to raise fluids. This includes bucket elevators, where a series of containers on a continuous chain or belt lift the liquid, and Archimedean screws, which move liquid along a revolving helical surface. It also covers air-lift pumps, where compressed air is injected into a pipe to reduce the density of the liquid column, causing it to rise. The classification is determined by the mechanism of displacement; if the device does not fit the definition of a standard pump but still functions to elevate liquid, it falls under 8413.82. This classification follows GRI 1, as heading 8413 covers all pumps for liquids, and subheading 8413.82 serves as the residual category for elevators. These devices are often used in irrigation, drainage, or specialized industrial processes where traditional pumping is inefficient.

Common Misclassification

The most common misclassification occurs with centrifugal pumps under HS code 8413.70 or other rotary positive displacement pumps under HS code 8413.81. The distinction is that 8413.82 is reserved for "elevators" that do not use standard impeller or piston mechanisms. It is also sometimes confused with solid material elevators under HS code 8428.32.

FAQ

What is the HS code for liquid elevators?

The HS code for liquid elevators, which are distinct from standard mechanical pumps, is 8413.82.

How does a liquid elevator differ from a centrifugal pump?

A centrifugal pump uses a rotating impeller to create pressure, while a liquid elevator uses buckets, screws, or air to physically lift the liquid.
