Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If output does not exceed 40 MW
Turbines with lower output fall under the 'not exceeding 40 MW' subheading in the same tariff line.
If driven primarily by combustion gases
Gas or combustion turbines use different working fluids and are covered in heading 8411.
If imported as replacement rotor or stator components
Parts of steam turbines are classified separately from complete turbines.
