8407.34.35.90 - Other

This HTS classification, 8407.34.35.90, pertains to spark-ignition internal combustion piston engines specifically designed for installation in tractors suitable for agricultural use, exceeding 37.3 kW in output, and not otherwise specified. These are reciprocating piston engines that utilize spark ignition to combust the fuel-air mixture, and are a more powerful variant within the category of engines for agricultural tractors.

The distinction from sibling categories, such as 8407.34.35.60 (Air-cooled), lies in the cooling mechanism. While this "Other" category encompasses engines that are not air-cooled, typically implying liquid-cooled systems, the air-cooled designation explicitly covers engines cooled by the circulation of air. This classification "Other" serves as a catch-all for engines meeting all the preceding criteria but not fitting into more specific cooling method sub-classifications.

As this node is a leaf node, there are no further subcategories. Therefore, the classification rests upon the precise fulfillment of the preceding criteria: being a spark-ignition reciprocating piston engine, intended for agricultural tractors, with a cylinder capacity exceeding 2,000 cc, an output exceeding 37.3 kW, and not being air-cooled. Examples within this category would include liquid-cooled gasoline engines that meet these power and application specifications.
