8407.34.35.60 - Air-cooled 🖩

This classification specifically pertains to spark-ignition reciprocating internal combustion piston engines designed for the propulsion of vehicles falling under Chapter 87 of the Harmonized Tariff Schedule. To qualify for this category, the engine must have a cylinder capacity exceeding 2,000 cubic centimeters and be intended for installation in tractors suitable for agricultural use. Furthermore, these engines must have a power output exceeding 37.3 kW. The "Air-cooled" designation highlights a key physical characteristic of these engines, indicating their cooling mechanism.

This category is distinct from its sibling "Other" (8407.34.35.90) by its precise specifications. While both are subcategories of engines exceeding 2,000 cc for agricultural tractors and a specific power output, the differentiating factor is the "Air-cooled" attribute. The "Other" category would encompass engines meeting all other criteria but utilizing different cooling methods, such as liquid cooling.

As this is a leaf node, there are no further subcategories. Therefore, the classification ends with engines that are spark-ignition, reciprocating piston type, used for agricultural tractors of Chapter 87, exceeding 2,000 cc cylinder capacity, exceeding 37.3 kW power output, and employing air-cooling as their primary cooling system. Classification within this specific code requires all these criteria to be met.
