8466.20.10.10 - Jigs and fixtures 🖩

This HTS subcategory, 8466.20.10.10, specifically classifies work holders designed for use with machine tools engaged in the cutting of gears. These work holders are critical components that securely grip and position workpieces (blanks) to ensure precise and accurate gear tooth formation during the machining process. Examples include specialized chucks, vises, or mandrels engineered to accommodate the specific geometry and rotational requirements of gear cutting operations.

Distinguished from its sibling category, 8466.20.10.90 ("Other"), this classification is narrowly focused on work holders *solely or principally* used for gear cutting. The sibling category would encompass work holders for other types of machining operations performed by the machines of headings 8456 to 8465, such as milling, drilling, or grinding operations that do not involve gear tooth generation. The key differentiator lies in the intended application and the specific design features of the work holder to facilitate the precise manipulation of material during gear manufacturing.

As this is a leaf node, there are no further subcategories within 8466.20.10.10. Classification at this level hinges on confirming that the work holder is indeed intended for use with gear-cutting machine tools and possesses the necessary characteristics to support this specialized function. The primary focus for classification is the functional purpose of the work holder in relation to the specific machining operation.
