8407.34.05.60 - Air-cooled

This classification covers internal combustion piston engines designed for the propulsion of vehicles classified under Chapter 87 of the Harmonized Tariff Schedule, specifically those with a cylinder capacity exceeding 1,000 cc but not exceeding 2,000 cc. Crucially, these engines are intended for installation in tractors suitable for agricultural use and must have a power output exceeding 37.3 kW. The "Air-cooled" designation indicates the primary method of heat dissipation for these specific engines.

Distinguishing this category from its sibling, 8407.34.05.90 "Other," hinges on the specific application and power rating. While both fall under spark-ignition reciprocating piston engines for vehicles of Chapter 87 with a 1,000 cc to 2,000 cc capacity, this subcategory is exclusive to engines designed for agricultural tractors and exceeding 37.3 kW. The "Other" category would encompass engines within the same displacement range but intended for different vehicle types, or those below the 37.3 kW threshold when used in agricultural tractors.

As a leaf node, this category does not have further subcategories. Therefore, classification into this specific code is determined by the definitive presence of all the outlined characteristics: spark-ignition reciprocating piston engine, intended for vehicles of Chapter 87, cylinder capacity between 1,000 cc and 2,000 cc, designed for agricultural tractors, power output exceeding 37.3 kW, and employing an air-cooling system.
