View full HS code details

Industrial steam turbines with a power output exceeding 40MW are classified under HS code 8406.81. This classification is part of the broader heading 8406, which covers steam turbines and other vapor turbines. The Harmonized System distinguishes turbines based on two primary criteria: their application (marine propulsion versus stationary use) and their power output capacity. Subheading 8406.81 is specifically designated for turbines that are not used for marine propulsion and have a rated output exceeding 40 megawatts. These machines are critical components in large-scale power generation and heavy industrial applications, where they convert thermal energy from pressurized steam into mechanical work. The classification process requires technical documentation verifying the turbine's maximum continuous rating (MCR). Because these units are often shipped in a disassembled state due to their immense size, General Interpretative Rule 2(a) is frequently applied, allowing the components to be classified as the complete turbine if they provide the essential character of the finished machine.

Products Included

  • Large-scale vapor turbines for geothermal energy

Common Misclassification

Industrial steam turbines are often confused with marine turbines classified under 8406.10. Even if the technical specifications are similar, the intended use on a vessel dictates the 8406.10 code. Another frequent error is misclassifying based on output; turbines with an output of 40MW or less must be classified under 8406.82. Additionally, gas turbines are classified under a completely different heading, 8411, and should never be confused with the steam-driven units of 8406.

FAQ

What is the HS code for industrial steam turbines?

For industrial steam turbines with an output exceeding 40MW, the HS code is 8406.81.

Does this code include the generator?

No, if the turbine is imported coupled with an electrical generator, the entire assembly is classified as a "generating set" under heading 8502.
