8407.34.35 - To be installed in tractors suitable for agricultural use

This HTS classification covers spark-ignition reciprocating piston engines specifically designed for installation in tractors intended for agricultural use. These engines are characterized by their internal combustion design and are part of the broader machinery and mechanical appliance chapter. They are distinct from engines intended for other types of vehicles, as defined by chapter 87.

The engines classified under 8407.34 are of the reciprocating piston type, with a cylinder capacity exceeding 2,000 cc. This specific subheading, 8407.34.35, further narrows the scope to those engines that will be installed in tractors suitable for agricultural use, distinguishing them from engines intended for other vehicle types that might fall under sibling categories such as those for specific truck or passenger vehicle subheadings.

Within this category, a further distinction is made based on power output. The subcategories differentiate engines that do not exceed 37.3 kW from those that exceed this power threshold. This subdivision is crucial for accurate classification, allowing for more granular tracking and potential duty rate differentiation based on engine performance and application.
