Steam Turbine Bellows Expansion Joint
A multi-ply stainless steel bellows expansion joint that compensates for thermal expansion between turbine casing sections. It is a part of a steam turbine of heading 84.06, specifically for turbines of 8406.81.00 or 8406.82.00. As it is not a rotor, blade, or repair/remanufacture part, it falls under 8406.90.39 as 'other' parts.

Import Tips & Compliance
• Ensure the bellows is classified as a part for turbines of 8406.81.00 or 8406.82.00, not 8406.10.00
• Provide CBSA with material certifications for stainless steel to support the application
• Check if the bellows qualifies for a duty reduction under a free trade agreement with the country of origin

Steam Turbine Bearing Housing
A bearing housing that encases and supports journal or thrust bearings in steam turbines, maintaining shaft alignment under high loads. It is a part of a steam turbine of heading 84.06, specifically for turbines of 8406.81.00 or 8406.82.00. As it is not a rotor, blade, or repair/remanufacture part, it falls under 8406.90.39 as 'other' parts.
Steam Turbine Blade Carrier Disc
Forged discs that serve as carriers for turbine blades, providing structural support in high-pressure stages of steam turbines. They are parts of a steam turbine of heading 84.06, specifically for turbines of 8406.81.00 or 8406.82.00. As they are not rotors, blades, or repair/remanufacture parts, they fall under 8406.90.39 as 'other' parts.
Steam Turbine Blade Locking Kit
Specialized pins, keys, and rivets that secure blades to turbine discs against centrifugal forces, sold as maintenance kits. They are parts of a steam turbine of heading 84.06, specifically for turbines of 8406.81.00 or 8406.82.00. As they are not rotors, blades, or repair/remanufacture parts, they fall under 8406.90.39 as 'other' parts.
Steam Turbine Coupling Shaft
High-strength forged shafts that connect turbine rotors to generators or loads, transmitting rotational power. They are parts of a steam turbine of heading 84.06, specifically for turbines of 8406.81.00 or 8406.82.00. As they are not rotors, blades, or repair/remanufacture parts, they fall under 8406.90.39 as 'other' parts.
Steam Turbine Diaphragm Staging
Steam turbine diaphragm staging assemblies consist of stationary diaphragm rings with precision-mounted guide vanes that direct steam flow onto the rotating blades for optimal energy extraction. These components are essential for controlling steam pressure and velocity through the turbine stages, and are classified as 'other' parts under tariff item 8406.90.39, distinct from rotors, blades, or casings.
Steam Turbine Emergency Overspeed Governor
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.
