Cast 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. Classified under HTS 8411.91.10.40 as a cast-iron part of turbojets not advanced beyond basic cleaning and machining, specific to non-aircraft turbines.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of steel or advanced beyond basic machining
Steel parts or those with additional machining fall under other parts provisions for turbojets, outside the cast-iron rough state subheading.
If imported as a set with gears for industrial pump use
Gearing components for speed changers may reclassify if sold as a functional set rather than isolated turbine parts.
If for general industrial machinery, not specifically gas turbines
Basic cast iron castings for non-turbine machinery like pumps are classified by material and use under Chapter 73.

Import Tips & Compliance
• Verify cast iron composition via material certificates to confirm eligibility under the cast-iron subheading
• Include detailed foundry process documentation proving no advanced machining beyond fin/gate removal
• Avoid misclassification by distinguishing from finished assemblies; common pitfall is overlooking 'non-aircraft' specificity
