8411.99.90.81 - Steel forgings

HTS code 8411.99.90.81 specifically classifies steel forgings that are intended for use as parts of non-aircraft gas turbines. This category encompasses components manufactured through the forging process from steel, which are then utilized in the construction or repair of industrial gas turbines. The emphasis is on the material (steel) and manufacturing method (forging) of these parts, distinguishing them from other types of turbine parts or components made from different materials.

This particular subcategory is distinct from its sibling, 8411.99.90.85, which covers "Other" parts for non-aircraft gas turbines that do not meet the specific criteria of steel forgings. While both fall under the broader "Other" parts of non-aircraft gas turbines, 8411.99.90.81 requires the component to be a steel forging. This means that components that are not made of steel, or are not produced via a forging process (e.g., machined castings, fabricated sheet metal parts), would generally be classified under the sibling category.

As a leaf node, 8411.99.90.81 has no further subdivisions. Therefore, the classification hinges on whether a specific steel forged part is indeed an integral component of a non-aircraft gas turbine. Examples of items that would fall here include forged compressor blades, turbine discs, or shafts made from steel, specifically designed for use in industrial gas turbines for power generation or other stationary applications. The classification relies on confirming the material composition, manufacturing technique, and intended application of the forged steel part.
