Engines; outboard motors for marine propulsion, spark-ignition reciprocating or rotary internal combustion piston engines

HS v2022 Code: 840721

About engines; outboard motors for marine propulsion, spark-ignition reciprocating or rotary internal combustion piston engines

HS code 840721 covers outboard motors for marine propulsion, a critical component of the global maritime industry. These spark-ignition reciprocating or rotary internal combustion piston engines are essential for powering small to medium-sized watercraft, from recreational boats to commercial fishing vessels. As international trade and tourism continue to grow, the demand for reliable and efficient outboard motors remains high, making this industry a significant contributor to the broader economy.

Production process

The production of outboard motors classified under HS code 840721 involves several key steps. Manufacturers begin by casting or forging the engine block and cylinder heads, often using aluminum alloys for lightweight construction. The crankshaft, pistons, and other internal components are then precisely machined and assembled. Specialized production equipment is used to install the ignition system, fuel delivery components, and cooling mechanisms. Finally, the outboard motor is tested, painted, and packaged for distribution.

Production inputs

The main inputs required for the production of HS code 840721 outboard motors include aluminum and other metal alloys for the engine block and components, as well as specialized machinery and tools for the manufacturing process. Manufacturers also rely on electronic components, such as ignition systems and fuel injectors, as well as various fasteners, seals, and other accessories. The production of these outboard motors also requires a skilled workforce capable of operating the specialized equipment and assembling the complex components.

Production outputs

Outboard motors classified under HS code 840721 are primarily used to power small to medium-sized watercraft, such as recreational boats, fishing vessels, and small commercial ships. These engines are often consumed by industries classified under 890310 Inflatable boats, for pleasure or sports and 890392 Motorboats, other than outboard motorboats. The output of this industry also supports the broader 890 Ships, boats and floating structures sector, which includes the construction and maintenance of various types of watercraft.
