8466.93.60.30 - For metalworking machine tools for cutting, grinding or finishing gears 🖩

This classification covers specialized parts and accessories designed for use with metalworking machine tools specifically intended for cutting, grinding, or finishing gears. These are not general-purpose components but rather items with a defined function within the gear manufacturing process. Examples include specialized chucks, fixtures, or tool holders precisely engineered to hold and manipulate workpieces or cutting tools during gear production. The critical defining characteristic is their exclusive or principal application in machines covered by headings 8456 through 8461 that perform gear cutting, grinding, or finishing operations.

Distinguishing this category from its sibling, 8466.93.60.60 "Other," hinges on the specificity of application. While the "Other" category would encompass any remaining parts or accessories for machines of headings 8456 to 8461 that are not specifically provided for elsewhere, this particular subcategory is reserved for those parts that are directly involved in the gear-specific manufacturing processes. The material composition, such as cast iron not advanced beyond cleaning and machined only for the removal of fins, gates, sprues, and risers or to permit location in finishing machinery, is also a key determinant for inclusion here.

As this is a leaf node, there are no further subcategories. Therefore, classification into this HTS code relies on meeting all preceding criteria: the part must be for machinery covered by headings 8456 to 8461, it must be an accessory or part of the "other" nature within that scope, and its principal purpose must be for metalworking machines dedicated to cutting, grinding, or finishing gears. The specific mention of cast-iron parts, cleaned and minimally machined for specific purposes related to finishing, serves as a concrete example of items that would fall under this classification.
