HS Code 8408
Compression-Ignition (Diesel) Engines
HS code 8408 covers compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, used in heavy machinery and ships.
HS Code 8408 — Compression-Ignition (Diesel) Engines
This code applies to diesel and semi-diesel engines that operate through compression ignition. They are commonly used in heavy-duty vehicles, marine vessels, and stationary power generation due to their high torque and fuel efficiency. Classification depends on whether the engine is for vehicle, marine, or other industrial use.
What's included
- Diesel engines for trucks
- Marine diesel engines
- Stationary diesel motors
- Semi-diesel engines
What's excluded
- Gasoline engines → use
8407(Requires spark ignition.) - Turbo-jets → use
8411(Turbine-based propulsion, not piston-based.)
Common examples
- Cummins 6BT diesel engine
- Wärtsilä marine diesel engine
- Caterpillar C15 industrial engine
- Scania truck engine
Frequently asked questions
Are emissions standards checked at customs?
Yes, many countries require certificates of conformity to environmental or emissions standards (e.g., EPA or Euro 6) for engines.
Trade & shipping notes
- Typical duty range: 3% - 15%
- Documentation: State end-use (e.g., marine vs. vehicle) as this affects the duty rate significantly.
