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, 8408.90.90.50, specifically covers compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, whose power output exceeds 1,119 kilowatts (kW). These are typically powerful engines designed for heavy-duty industrial applications, large marine vessels, or substantial power generation systems where significant horsepower is required. The classification is determined by the engine's maximum continuous power rating, a critical factor for customs assessment.

Distinguishing this category from its siblings is solely based on power output. While all share the commonality of being "other" compression-ignition engines not specified elsewhere in the 8408.90.90 subheadings, 8408.90.90.50 is reserved for the most powerful units. It differs from 8408.90.90.10 (not exceeding 149.2 kW), 8408.90.90.20 (exceeding 149.2 kW but not exceeding 373 kW), 8408.90.90.30 (exceeding 373 kW but not exceeding 746 kW), and 8408.90.90.40 (exceeding 746 kW but not exceeding 1,119 kW) by its threshold of surpassing 1,119 kW.

As this is a leaf node, there are no further subcategories within 8408.90.90.50. Therefore, the primary classification criterion for goods falling under this heading remains their power output exceeding 1,119 kW, in addition to meeting the general requirements of being a compression-ignition internal combustion piston engine. Importers should ensure accurate documentation of the engine's rated power to ensure correct classification.
