8407.34.55.00 - Other

This category, HTS 8407.34.55.00, classifies "Other" spark-ignition reciprocating internal combustion piston engines that exceed 2,000 cubic centimeters in cylinder capacity. These engines are specifically designed for use as the primary power source in vehicles classified within Chapter 87 of the HTS. They are not intended for agricultural tractors (as per sibling 8407.34.35) nor are they specifically destined for the specialized heavy-duty trucks or buses falling under specific subheadings within the 8701, 8702, 8703, or 8704 headings, which have their own distinct classifications.

The "Other" designation indicates that this subheading encompasses engines meeting the general criteria of spark-ignition, reciprocating piston design, internal combustion, for vehicle propulsion, over 2,000 cc displacement, but which do not fit into the more specific sibling categories. This could include engines for various types of recreational vehicles, performance automobiles, or other motor-powered conveyances not explicitly enumerated in the preceding subheadings. Classification at this level hinges on the engine's physical specifications and its intended application, excluding those with a clearly defined alternative classification.
