Steam Turbine Generator Coupling from United States
Steam turbine generator couplings are flexible disc or gear-type couplings that synchronize turbine and generator shafts for grid-stable operation, offering high misalignment tolerance for base-load power plants. These couplings are classified as 'other' parts under tariff item 8406.90.39, as they are not rotors, blades, or other specifically named turbine components.

Import Tips
• Describe the coupling as a part of a steam turbine on customs documentation, specifying its function in power transmission
• If the coupling is imported separately from the turbine, ensure it is not classified as a general transmission shaft under heading 84.83
• Verify whether the coupling meets Canadian electrical safety standards if it includes any electrical components
