Steam Turbine Nozzle Ring Assembly from Japan
Steam turbine nozzle ring assemblies consist of circular arrays of precision nozzles that accelerate steam into high-velocity jets impinging on turbine blades, optimizing expansion efficiency. These assemblies 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
• Clearly identify the nozzle ring as a stationary part of the turbine to distinguish it from rotating blades
• Provide technical drawings showing the nozzle geometry to support classification
• If the nozzle ring is imported with blades, consider whether the set constitutes a complete stage requiring different classification
