8407.21.00 - Outboard motors

HTS Code 8407.21.00 specifically classifies outboard motors, which are self-contained internal combustion engines designed to be attached to the transom of a boat for propulsion. These engines typically include an integrated gearbox and propeller assembly, making them a complete propulsion unit. The defining characteristic of this classification is their direct application as an outboard propulsion system for marine vessels.

This category stands apart from its sibling, 8407.29.00 ("Other" marine propulsion engines), by its specific design and function as an outboard unit. While 8407.29.00 would encompass inboard marine engines or other forms of marine propulsion not classified under 8407.21.00, this heading is exclusively for engines mounted externally to the hull.

Further subdivision within 8407.21.00 is based on engine power output. Subcategory 8407.21.00.40 covers outboard motors with a power rating less than 22.38 kW, typically smaller engines suited for dinghies, small fishing boats, or auxiliary propulsion. The broader subcategory, 8407.21.00.80 ("Other"), encompasses all outboard motors with a power rating of 22.38 kW and above, including those used for larger vessels and performance applications.
