Cast Iron Gas Turbine Compressor Casing
A rough-machined cast iron housing for the compressor section of industrial gas turbines used in power generation. It is cast from iron, cleaned, and machined only to remove fins, gates, sprues, risers, or for fixture location, fitting HTS 8411.99.1010 as a part of nonaircraft gas turbines not advanced beyond basic preparation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If machined beyond fin/gate removal, such as precision boring
Advanced machining beyond cleaning and locator prep moves it to 'other' metal gas turbine parts.
If not specifically designed as gas turbine component
General cast iron castings for machinery fall under Chapter 73 if lacking turbine-specific design.
If imported as part of a complete pump or compressor set
Gears, casings, and similar for pumps/compressors classify in 8483 if not identified solely for gas turbines.

Import Tips & Compliance
• Verify casting composition meets cast-iron standards via mill test reports to avoid misclassification as steel parts
• Document machining is limited to cleaning/fin removal; excess processing shifts to 8411.99.1080
• Include end-use certification proving nonaircraft application to prevent aircraft turbine scrutiny
