8408.90.90.10 - Not exceeding 149.2 kW

This HTS classification, 8408.90.90.10, specifically covers compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, that do not exceed 149.2 kilowatts (kW) in power output. These engines are utilized in a wide array of applications where reliable power generation is required, and their classification is determined by their power rating.

The key distinguishing factor for this category lies in its defined power limit. Sibling categories, such as 8408.90.90.20 and beyond, encompass engines with progressively higher power outputs, ranging from exceeding 149.2 kW up to significantly larger capacities. Therefore, an engine falling under 8408.90.90.10 would be distinctly categorized from one producing more than 149.2 kW, regardless of other shared characteristics.

As this node is a leaf node, there are no further subdivisions. Classification within this specific category is therefore solely based on confirming that the engine is a compression-ignition type and its maximum power output does not surpass the 149.2 kW threshold. This ensures accurate tariff application for a broad spectrum of smaller-to-medium-sized diesel engines.
