HS Code for Lobe pump

Lobe pumps are classified under HS code 8413.60, which covers rotary positive displacement pumps for liquids. The classification is based on the mechanical principle of the pump's operation. Lobe pumps utilize two or more rotating lobes that trap fluid between the lobes and the pump casing, moving it from the inlet to the outlet. Because they do not use a reciprocating motion (like a piston) and are not centrifugal (which uses kinetic energy), they fall into the category of 'other' rotary positive displacement pumps. This classification is guided by the Explanatory Notes to heading 8413, which specify that the heading includes pumps for liquids whether or not fitted with a measuring device. The lobe pump's ability to handle high-viscosity fluids and solids without damaging them makes it a staple in the food, chemical, and pharmaceutical industries, but its HS classification remains strictly tied to its rotary displacement mechanism rather than its end-use industry.

Common Misclassification

Lobe pumps are often misclassified under HS code 8413.50, which is designated for reciprocating positive displacement pumps. The distinction is mechanical: reciprocating pumps use a back-and-forth motion, while lobe pumps use rotation. Additionally, they may be confused with HS code 8413.70 for centrifugal pumps. Centrifugal pumps are the most common liquid pumps, but they operate on a completely different physical principle involving an impeller. Using the incorrect code can lead to issues with customs valuation and regulatory compliance, especially in jurisdictions with specific energy efficiency standards for different pump types.

FAQ

What is the HS code for lobe pump?

The HS code for a lobe pump is 8413.60, as it is a rotary positive displacement pump for liquids.

Does the material of the pump affect the HS code?

Generally, no. Whether the lobe pump is made of stainless steel for food grade use or cast iron for industrial use, it remains under 8413.60 based on its mechanical operation.
