8411.91.10.60 - For use in civil aircraft

This HTS category, 8411.91.10.60, specifically covers parts of turbojets or turbopropellers that are manufactured from cast iron. The defining characteristic of these parts is that their manufacturing process has not advanced beyond initial cleaning and has undergone machining solely for the removal of fins, gates, sprues, and risers, or to facilitate their placement in finishing machinery. Crucially, these parts must be intended for use in civil aircraft to fall under this classification.

This classification distinguishes itself from its sibling, 8411.91.10.90 "Other," by its strict material (cast iron) and the limited nature of its processing. While the "Other" category may encompass cast-iron parts with more extensive machining or other types of parts for aircraft turbines, this specific code targets a very narrowly defined set of cast-iron components at a less processed stage. The focus is on the initial shaping and preparation of cast-iron components destined for aircraft turbine applications.

As this is a leaf node within the HTS, there are no further subcategories. The classification relies on meeting all the stipulated criteria: being a part of a turbojet or turbopropeller, made of cast iron, having undergone only basic cleaning and specific, limited machining, and being designated for use in civil aircraft. Importers and exporters must carefully verify these attributes to ensure accurate classification and compliance with customs regulations.
