8407.90.90.60 - 4,476 W or greater but not exceeding 18.65 kW

This HTS classification covers spark-ignition reciprocating or rotary internal combustion piston engines that fall within a specific power range. Specifically, these engines have a power output of 4,476 Watts or greater but do not exceed 18.65 kilowatts. This category is designed for engines that do not fit into the lower or higher power bands delineated by the sibling categories.

The distinction between this category and its siblings is solely based on power output. Category 8407.90.90.20 applies to engines producing less than 746 W, while 8407.90.90.40 covers engines between 746 W and 4,476 W. Conversely, 8407.90.90.80 is for engines exceeding 18.65 kW. Therefore, accurate measurement and verification of the engine's rated power are crucial for correct classification.

As this classification is a leaf node, there are no further subcategories. This means that any spark-ignition reciprocating or rotary internal combustion piston engine meeting the specified power requirement of 4,476 W to 18.65 kW will be classified directly under 8407.90.90.60, provided it is not specifically excluded by notes within Chapter 84 or Section XVI, or by other applicable tariff provisions. Examples of engines that might fall into this category include those used in certain types of industrial equipment, small boats, or agricultural machinery.
