Steam Turbine Emergency Overspeed Governor from China
Steam turbine emergency overspeed governors are mechanical backup devices that detect rotor overspeed and independently trigger steam valve closure, providing redundant safety protection required in nuclear power plants. These governors are classified as 'other' parts of steam turbines under tariff item 8406.90.39, as they are not rotors, blades, or other specifically named components.

Import Tips
• Classify the governor as a part of a steam turbine and include its function in the product description for customs clearance
• If the governor contains electronic components, verify whether those components affect classification under Chapter 85
• Keep records of the safety certifications (e.g
• ASME) to demonstrate compliance with Canadian standards
