8407.33.10.30 - Not exceeding 37.3 kW 🖩

This HTS classification, 8407.33.10.30, specifically pertains to spark-ignition reciprocating internal combustion piston engines designed for the propulsion of vehicles classified under Chapter 87. The defining characteristic of this subcategory is that the engines have a cylinder capacity exceeding 250 cubic centimeters but not exceeding 1,000 cubic centimeters, and are intended for installation in tractors suitable for agricultural use. This precisely defines the scope of engines that meet these specific displacement and intended application criteria.

Distinguishing this category from its sibling, "Exceeding 37.3 kW," is crucial. While both fall under engines for agricultural tractors of a certain cylinder capacity, this classification focuses on engines with a power output **not exceeding 37.3 kW**. The sibling category would encompass engines of the same cylinder capacity range but with a higher power output. Therefore, the power rating is the primary differentiating factor at this level.

As this is a leaf node within the HTS, there are no further subcategories. The classification is complete at this level, signifying that engines meeting all preceding criteria – spark-ignition, reciprocating piston, for vehicle propulsion, specific cylinder capacity range, intended for agricultural tractors, and not exceeding 37.3 kW – are definitively classified here. Examples include small to medium-sized gasoline engines used in utility tractors for smaller farms or specialized agricultural tasks.
