8466.93.75.00 - Of metalworking machine tools for cutting gears

This HTS subcategory, 8466.93.75.00, specifically covers metalworking machine tool attachments and accessories made of metal that are designed for cutting gears. This includes a wide range of components such as specialized chucks, collets, mandrels, and other work-holding devices that are essential for accurately and efficiently performing gear-cutting operations on machines classified within headings 8456 to 8461. The primary function of these items is to securely hold the workpiece or the cutting tool during the gear manufacturing process.

Distinguishing this category from its siblings involves a focus on the precise application: gear cutting. While other subcategories within 8466.93.75 might cover general-purpose tool holders or attachments for other metalworking operations (like drilling, milling, or grinding), this node is exclusively for equipment integral to the specialized task of producing gears. The material composition, being metal, is also a defining characteristic, aligning with the broader scope of heading 8466 which includes metal parts.

As this node is a leaf category in the HTS, there are no further subdivisions. Therefore, the classification of an item within 8466.93.75.00 hinges on its explicit suitability and principal use for gear-cutting machinery, its construction from metal, and its role as a work or tool holder, or a specialized attachment for such machines. Importers must ensure that the accessory's design and function are directly related to the creation of gears to correctly apply this classification.
