HS Code 8406
Steam and Vapour Turbines
HS code 8406 is used for steam and other vapour turbines, critical components in electricity generation and large-vessel propulsion systems worldwide.
HS Code 8406 — Steam and Vapour Turbines
This heading covers turbines that convert the thermal energy of pressurized steam or other vapours into mechanical work. These are primarily used in power plants and large-scale industrial propulsion systems. It includes both stationary turbines and those used for marine propulsion.
What's included
- Marine propulsion steam turbines
- Condensing turbines
- Non-condensing back-pressure turbines
- Turbo-pumps and turbo-blowers
What's excluded
- Gas turbines → use
8411(Powered by combustion gases rather than steam.) - Water turbines → use
8410(Powered by liquid water pressure.)
Common examples
- GE 700MW steam turbine for power plant
- Mitsubishi marine steam turbine
- Waste heat recovery vapour turbine
- Industrial back-pressure turbine
Frequently asked questions
Does this include the electric generator attached to the turbine?
No, if the turbine and generator are presented together, they are usually classified as a generator set under heading 8502.
