HS Code for Power generation turbines
Steam turbines used for large-scale power generation with an output exceeding 40 MW are classified under HS code 8406.81. Heading 8406 is specifically designated for steam turbines and other vapor turbines. These machines are essential components in thermal power plants, where they convert the energy of pressurized steam into rotary motion to drive electrical generators. The classification within Heading 8406 is hierarchical: first, it distinguishes between turbines for marine propulsion and "other" turbines. For non-marine applications, the subheadings are then divided by power output. Subheading 8406.81 is the specific code for turbines with an output exceeding 40 MW, reflecting the large-scale equipment used in utility-grade power stations, including coal, nuclear, and concentrated solar thermal plants.
Products Included

Common Misclassification
The most common misclassification is using HS code 8406.82, which is for steam turbines with an output not exceeding 40 MW. Importers must verify the maximum continuous rating (MCR) of the turbine to choose the correct code. Another error is confusing steam turbines with gas turbines (8411). While both are used in power generation, steam turbines require an external boiler to produce vapor, whereas gas turbines are internal combustion engines. Finally, complete generating sets (turbine plus generator) are often incorrectly classified here instead of Heading 8502.
FAQ
What is the HS code for Power generation turbines?
Large-scale steam turbines for power generation with an output exceeding 40 MW are classified under HS code 8406.81.
Does this code include the electrical generator?
No, HS code 8406.81 covers the turbine only. If the turbine and generator are presented together as a single functional unit, the entire assembly is typically classified under Heading 8502 as an electric generating set.
