8407.33.90.80 - Exceeding 18.65 kW

This HTS code, 8407.33.90.80, specifically classifies spark-ignition internal combustion piston engines that are designed for the propulsion of vehicles under Chapter 87, have a cylinder capacity exceeding 250 cubic centimeters but not exceeding 1,000 cubic centimeters, and importantly, have a power output exceeding 18.65 kW. These are typically found in a range of light to medium-duty vehicles, including motorcycles, certain ATVs, and smaller automotive applications where engine performance beyond a specific threshold is required.

The key differentiator for this subcategory, 8407.33.90.80, lies in its power output. It is distinctly separated from its sibling category, 8407.33.90.40, which covers engines of the same engine type and capacity range but with a power output not exceeding 18.65 kW. Therefore, the classification hinges on a precise measurement of the engine's maximum continuous power output.

As this is a leaf node in the HTS classification system, there are no further subcategories under 8407.33.90.80. The classification is complete at this level, focusing on the combination of engine type, intended use, cylinder capacity, and power output to uniquely identify these specific internal combustion engines. Importers and exporters should ensure accurate documentation regarding engine specifications to ensure correct classification.
