8407.34 - Of a cylinder capacity exceeding 1,000 cc:

This HTS category, 8407.34, specifically classifies spark-ignition reciprocating internal combustion piston engines designed for the propulsion of vehicles of chapter 87, where the engine's cylinder capacity *exceeds 1,000 cubic centimeters (cc)*. These are typically found in larger passenger vehicles, trucks, buses, and other heavy-duty applications. The core function is converting fuel into mechanical power to drive vehicle wheels.

Distinguishing this category from its siblings, 8407.31, 8407.32, and 8407.33, is solely based on the engine's total cylinder displacement. While siblings cover smaller capacity engines, 8407.34 is reserved for those with a capacity *greater than 1,000 cc*, signifying engines with higher power output and typically larger engine dimensions. This specific displacement threshold is the primary determinant for classification within this branch.

The subcategories under 8407.34 further refine the classification based on even larger engine capacities. The first subcategory covers engines with a cylinder capacity *not exceeding 2,000 cc*, while the second addresses those with a cylinder capacity *exceeding 2,000 cc*. This granular approach allows for more precise tracking and statistical reporting of different engine sizes used in various automotive and vehicular applications.
