About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification, 8408.90.90.40, pertains to compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, with a specific power output range. Goods classified here are "other" engines within the broader category of non-reciprocating internal combustion engines. The defining characteristic for this subcategory is their engine power: they must exceed 746 kilowatts (kW) but not exceed 1,119 kilowatts (kW). This power range is critical for distinguishing these engines from other, lower or higher-powered diesel engines.

To accurately classify an engine within HTS code 8408.90.90.40, it is essential to consult its rated output. This category is distinct from its siblings which cover engines with lesser power outputs, such as those not exceeding 149.2 kW (8408.90.90.10), exceeding 149.2 kW but not exceeding 373 kW (8408.90.90.20), and exceeding 373 kW but not exceeding 746 kW (8408.90.90.30). Conversely, engines with a power output exceeding 1,119 kW would fall under sibling category 8408.90.90.50.

As this classification represents a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the precise power output is the sole differentiating factor at this level, making accurate measurement and documentation of the engine's kilowatt rating paramount for correct customs declarations. Examples of engines that might fall under this category include larger industrial diesel engines used in heavy machinery, generators, or marine propulsion systems where substantial power generation is required.
