Cleaned Vapor Turbine Rotor for Cogeneration Plants
A rotor for organic vapor turbines in cogeneration facilities, processed only by cleaning and minimal machining to eliminate sprues, risers, and fins from casting. This semi-finished state permits accurate fixturing for subsequent finishing operations. Classified in 8406.90.60.00 due to restriction to basic preparation without blade attachment or balancing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blades or vanes already assembled
Assembled rotors with blades are 'finished parts' under the more advanced 8406.90.10 provision.
If designed for electric generator coupling
Rotors primarily for generators fall under Chapter 85 electric machinery parts.
If bulk castings without turbine-specific machining
General steel forgings/rough castings go to Chapter 73 before specific part classification.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Include process flow diagrams showing only fin/gate removal to prevent customs disputes on advancement level
• Label as 'semi-finished rotor for turbine finishing' to aid clear classification during entry
