Cast Iron Gas Turbine Inlet Housing
A rough cast-iron inlet manifold for non-aircraft industrial gas turbines, machined solely for gate removal and fixture location in finishing equipment. While it is for gas turbines, it is not specifically for turbo-jets or turbo-propellers, so it may not fall under this item.
8411.91.00Cast Iron Generator Drive Shaft Casting
A basic cast-iron shaft blank for coupling turbojets to generators in non-aircraft power plants, with minimal machining for sprue removal. This unfinished part is designed for turbojet engines, even in non-aircraft applications, and falls under parts of turbo-jets.
8411.91.00Cast Iron Non-Aircraft Turbine Nozzle Ring
A rough-machined cast-iron nozzle guide vane ring for industrial non-aircraft gas turbines, prepared only by cleaning casting flash and risers. This part is for gas turbines but not specifically for turbo-jets or turbo-propellers, so it may not be classified under this item.
8411.91.00Cast Iron Turbine Exhaust Collector
A rough cast-iron collector for exhaust gases from non-aircraft turbopropellers, cleaned and located-machined only. This unfinished part is specifically for turbopropeller engines, even in non-aircraft applications, and falls under parts of turbo-propellers.
8411.91.00Cast Iron Turbofan Diffuser Rough Part
A preliminary cast-iron diffuser component for non-aircraft turbofan gas turbines, with only fins, gates, and sprues removed for machining setup. Turbofan engines are a type of turbojet, so this part falls under parts of turbo-jets.
8411.91.00Cast Iron Turbojet Combustion Chamber Support
A basic cast-iron support bracket for turbojet combustion chambers, processed only by cleaning and minimal machining to remove casting artifacts or permit fixture placement. It is an unfinished part specifically designed for turbojet engines, falling under the parts of turbo-jets or turbo-propellers.
8411.91.00Cast Iron Turbojet Compressor Casing
A rough cast-iron housing for the compressor section of a non-aircraft turbojet engine, machined only to remove casting imperfections like fins and gates for subsequent finishing. This unfinished part is specifically for turbojet engines, falling under parts of turbo-jets.
8411.91.00Cast Iron Turbojet Compressor Housing
A rough cast-iron housing for the compressor section of a turbojet engine, cleaned and minimally machined only to remove casting imperfections like fins, gates, sprues, and risers, or for fixture placement. This unfinished component is dedicated to turbojet engines, making it a part of turbo-jets under this tariff item.
8411.91.00Cast Iron Turbojet Exhaust Nozzle Flange
An unfinished cast-iron flange for attaching exhaust nozzles in turbojet engines, with limited processing including cleaning and machining only for casting defect removal or fixturing. As a component specifically for turbojet exhaust systems, it is classified as a part of turbo-jets.
8411.91.00Cast Iron Turbojet Inlet Duct Casting
A basic cast-iron component forming the air inlet duct for turbojet engines, processed only by cleaning and minimal machining to eliminate casting defects or enable fixturing. This unfinished part is integral to the turbojet's air intake system, falling under parts of turbo-jets.
8411.91.00Cast Iron Turboprop Gearbox Housing
A rough cast-iron housing for the reduction gearbox in turboprop engines, machined only to remove fins, gates, sprues, risers, or for locating in finishing equipment. This unfinished component is specifically for turbopropeller power sections, making it a part of turbo-propellers.
8411.91.00Cast Iron Turboprop Impeller Mounting Base
A rough cast-iron base plate for mounting impellers in turboprop compressors, cleaned and minimally machined solely to remove sprues, risers, fins, gates, or for finishing fixture location. This unfinished part is dedicated to turbopropeller engines, qualifying as a part of turbo-propellers.
8411.91.00Cast Iron Turboprop Shaft Bearing Housing
A rough cast-iron housing for shaft bearings in turbopropeller power sections, machined minimally for gate/sprue removal and fixturing only. This unfinished component is specifically for turboprop engines, falling under parts of turbo-propellers.
8411.91.00Cast Iron Turboprop Turbine Blade Rough Casting
A rough cast-iron turbine blade for turboprop engines used in non-aircraft applications like marine propulsion, cleaned and lightly machined only to remove sprues and risers. This unfinished part is specifically for turbopropeller engines, falling under parts of turbo-propellers.
8411.91.00Cast Iron Turboprop Turbine Case
A rough cast-iron outer case for the turbine section in turbopropeller engines, limited to cleaning and machining solely for fin, gate, sprue, and riser removal or finishing machine location. This unfinished part is integral to turboprop turbines, qualifying as a part of turbo-propellers.
