8407.34.05 - To be installed in tractors suitable for agricultural use

This HTS category encompasses spark-ignition reciprocating internal combustion piston engines specifically designed for installation in tractors classified under headings 8701 (tractors for agriculture or forestry) that are suitable for agricultural use. These engines are characterized by their spark-ignition combustion cycle and a reciprocating piston design, distinguishing them from rotary engines or compression-ignition engines (diesel engines). The primary application for these engines is to power agricultural tractors, implying specific design considerations for torque, power delivery, and integration within tractor systems.

This classification is distinct from its sibling categories. The sibling starting with ": To be installed in vehicles of subheading 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29, or heading 8702, 8703 or 8704:" covers engines intended for other types of vehicles, such as trucks, buses, or passenger vehicles, rather than agricultural tractors. The other sibling, "8407.34.25.00: Other," acts as a residual category for spark-ignition reciprocating piston engines of this cylinder capacity range that do not meet the specific criteria for installation in agricultural tractors or the aforementioned vehicle types.

Within this category, further subclassification is provided based on engine power output. The subcategory "8407.34.05.30: Not exceeding 37.3 kW" groups engines with a maximum power output of 37.3 kilowatts or less. Conversely, the subcategory ": Exceeding 37.3 kW:" is for engines whose power output surpasses this threshold. This distinction is crucial for trade statistics and regulatory purposes, reflecting varying engine sizes and capabilities relevant to the specific work performed by different types of agricultural tractors.
