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

HS v2017 Code: 840729

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

hs code 840729 covers a critical component of the marine industry - spark-ignition reciprocating or rotary internal combustion piston engines used for marine propulsion, excluding outboard motors. These engines play a vital role in powering a wide range of vessels, from small recreational boats to large commercial ships, making them an essential part of global trade and transportation networks.

Production process

The production of engines covered under hs code 840729 typically involves several key steps. First, the engine block and cylinder heads are cast from metal alloys, often aluminum or cast iron. The crankshaft, pistons, and other moving components are then machined to precise specifications. The engine is then assembled, with the fuel system, ignition system, and other auxiliary components integrated. Finally, the engine undergoes rigorous testing and quality control checks before being shipped to marine vessel manufacturers or distributors.

Production inputs

The main inputs required for the production of engines under hs code 840729 include metal alloys such as aluminum and cast iron for the engine block and components, as well as specialized machinery and tools for the machining and assembly processes. Additionally, the engines require fuel systems, ignition systems, and other electronic components to function properly. The production of these engines also relies on a skilled workforce with expertise in engine design, manufacturing, and testing.

Production outputs

The primary output of hs code 840729 is spark-ignition reciprocating or rotary internal combustion piston engines for marine propulsion, excluding outboard motors. These engines are then consumed by manufacturers of various types of marine vessels, including 890120 Tankers, 890130 Refrigerated vessels, 890190 Other vessels for the transport of goods and other vessels for the transport of both persons and goods, and 890400 Tugs and pusher craft.
