8413.30.90.60 - Lubricating pumps

This HTS category encompasses lubricating pumps designed for use with internal combustion piston engines. These pumps are specifically engineered to circulate lubricating oil throughout an engine's various components, reducing friction and wear. The classification applies to pumps whose primary function is lubrication within this specific engine type, regardless of whether they are part of a larger assembly or sold as standalone units.

Distinguishing this category from its sibling, 8413.30.90.30 (Fuel pumps), is crucial. While both are pumps for internal combustion piston engines, this category exclusively covers pumps for lubricating oil. Fuel pumps, on the other hand, are dedicated to delivering fuel to the engine. The "Other" designation within 8413.30.90.90 serves as a catch-all for pumps related to internal combustion piston engines that do not fall into the fuel or lubricating categories, such as cooling medium pumps.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 8413.30.90.60 relies on accurately identifying the pump's intended use as a lubricant for internal combustion piston engines. If a pump has a dual function, its classification will be determined by its principal use, or by the most specific description if no principal use can be determined.
