8413.30.90.30 - Fuel pumps

This HTS category, 8413.30.90.30, specifically classifies fuel pumps designed for use in internal combustion piston engines. These pumps are essential components responsible for delivering fuel from the vehicle's fuel tank to the engine's combustion chambers. They can vary in design and operating principle, including but not limited to electric fuel pumps, mechanical fuel pumps, and high-pressure direct injection pumps. The critical defining characteristic is their direct application in supplying fuel to the engine.

This category is distinguished from its sibling, 8413.30.90.60, which covers lubricating pumps. While both are pumps for internal combustion engines, lubricating pumps are dedicated to circulating oil for engine lubrication, whereas fuel pumps, as classified here, are solely responsible for fuel delivery. The residual category, 8413.30.90.90, is reserved for any other pumps for internal combustion engines that do not fall under the specific sub-classifications for fuel or lubricating pumps.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, the focus remains on the precise identification of fuel pumps for internal combustion piston engines, ensuring accurate distinction from other pump types based on their specific function within the engine's operation. Classification hinges on the intended use and the system within which the pump operates.
