8408.90.90.20 - Exceeding 149.2 kW but not exceeding 373 kW

This HTS classification, 8408.90.90.20, specifically designates compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, that fall within a defined power output range. These engines are characterized by their ability to generate between exceeding 149.2 kilowatts (kW) but not exceeding 373 kilowatts (kW) of power. This category encompasses a variety of engine sizes and applications where this specific power output is a defining characteristic.

The key differentiator for this category lies in its power output range. It is distinct from sibling categories that cover engines with lower power outputs (not exceeding 149.2 kW) and those with higher power outputs, such as exceeding 373 kW but not exceeding 746 kW, and further upwards. Therefore, the precise measurement of the engine's maximum power output is the primary criterion for determining its correct classification within this specific sub-heading.

As a leaf node, HTS 8408.90.90.20 does not have further subcategories. Classification within this code relies solely on confirming that the engine is a compression-ignition type and that its power output falls strictly between the specified limits of 149.2 kW and 373 kW. Examples of such engines might be found in medium-duty trucks, smaller marine vessels, or industrial machinery that requires a robust power source within this particular kilowatt range.
