8466.91.50.00 - Other

This HTS category, 8466.91.50.00, encompasses "Other" parts and accessories specifically designed for use with machines of heading 8464. Heading 8464 covers machine tools for working stone, ceramics, concrete, cement-atious materials or like rigid materials, or for cold-working glass. Therefore, this subheading would include components such as chucks, vices, clamping devices, positioning tables, and other specialized fixtures or attachments that are not specifically enumerated in other subcategories of 8466.91 but are intended for use with stone, ceramic, or glass working machinery.

This classification is distinguished from its sibling, 8466.91.10.00, which exclusively covers unfinished, cast-iron parts that have undergone only basic cleaning or minor machining for locating purposes. While both relate to accessories for heading 8464 machines, 8466.91.50.00 is for a broader range of finished or more complex components made from various materials, provided they are not specifically covered elsewhere. The key differentiator is the level of processing and the material specified in the sibling category.

As this is a leaf node, there are no further subdivisions under 8466.91.50.00. Classification within this category relies on ensuring the part or accessory is suitable for sole or principal use with machines of heading 8464 and does not fall under any other more specific HTS classification. The "Other" designation signifies it captures residual items that meet the general criteria for accessories to these specific machine tools but lack a more precise enumeration.
