8407.33.10.90 - Other

This HTS classification covers reciprocating piston engines designed for the propulsion of vehicles classified under Chapter 87, specifically those with a cylinder capacity exceeding 250 cubic centimeters but not exceeding 1,000 cubic centimeters. The key defining feature of this category is its intended application: these engines are manufactured to be installed in tractors that are suitable for agricultural use. Furthermore, these engines must have an output exceeding 37.3 kilowatts (kW).

This specific subcategory distinguishes itself from sibling entries by its precise criteria. While other engines within the 8407.33.10 range might be air-cooled (as indicated by sibling category 8407.33.10.60), this classification is defined by the engine's suitability for agricultural tractors and its power output threshold. The focus is on engines of a specific displacement range, intended for a particular type of vehicle application, and meeting a minimum power requirement, rather than solely on their cooling mechanism.

As this is a leaf node in the HTS classification, there are no further subcategories that subdivide this specific engine type. Therefore, classification at this level is conclusive. Importers and exporters should carefully verify that the engine meets all stipulated criteria, including its internal combustion type, reciprocating piston design, displacement range, intended use in agricultural tractors, and power output exceeding 37.3 kW, to ensure accurate classification.
