8407.34.18.00 - Other

This HTS category, 8407.34.18.00, encompasses "Other" spark-ignition reciprocating internal combustion piston engines designed for the propulsion of vehicles of Chapter 87. Specifically, it covers engines with a cylinder capacity exceeding 1,000 cubic centimeters but not exceeding 2,000 cubic centimeters, intended for installation in heavy-duty trucks (subheadings 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29), motor vehicles for the transport of persons (heading 8702), motor cars and other motor vehicles principally designed for the transport of persons (heading 8703), and motor vehicles for the transport of goods (heading 8704). The designation "Other" signifies that these engines do not fall under any more specific subheadings within this particular series.

The key differentiator for this classification lies in its residual nature, capturing engines that meet the engine type, cylinder capacity, and intended vehicle application criteria but are not otherwise specified. It is distinct from sibling category 8407.34.14.00, which exclusively covers engines that are explicitly identified as "used or rebuilt." This current classification applies to new engines or those not specifically designated as used or rebuilt.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level, requiring that imported or exported engines meeting all the outlined specifications be coded to 8407.34.18.00. Therefore, customs professionals should meticulously verify the engine's specifications, including its internal combustion type, reciprocating piston design, cylinder capacity range, and intended vehicle application, to ensure accurate classification.
