8408.10.00.50 - Exceeding 746 kW

This HTS category, 8408.10.00.50, specifically classifies marine propulsion engines that are of the compression-ignition internal combustion piston engine type (commonly known as diesel or semi-diesel engines) and possess a power output exceeding 746 kilowatts (kW). These are typically high-power engines designed for substantial maritime vessels such as large cargo ships, tankers, ferries, and offshore support vessels, where significant horsepower is required for efficient propulsion.

This classification is distinguished from its sibling categories by its specific power output threshold. Unlike categories 8408.10.00.05 through 8408.10.00.40, which cover engines with power outputs up to and including 746 kW, this category is reserved for engines that surpass that benchmark. Therefore, the primary distinguishing factor for classification into 8408.10.00.50 is the engine's rated power exceeding 746 kW.

As this is a leaf node, there are no further subdivisions within this specific HTS code. All marine diesel or semi-diesel engines exceeding 746 kW will fall directly under this classification, provided they meet the general criteria for Chapter 84. When classifying, it is crucial to verify the manufacturer's stated continuous maximum rating to ensure accurate placement within the correct power bracket.
