8458.91.50.70 - Other

This HTS subcategory, 8458.91.50.70, encompasses numerically controlled lathes that do not fall under the "multiple spindle" classification. These machines are designed for metal removal through turning operations, controlled by programmed instructions. The key characteristic distinguishing them from their sibling category is their single-spindle configuration, meaning they primarily operate with one workpiece and one spindle at a time for turning operations.

The scope of this classification includes a wide array of numerically controlled single-spindle lathes, such as vertical turret lathes (VTLs) and horizontal lathes, provided they are equipped with numerical control systems for automated operation. The "Other" designation at this level signifies that any numerically controlled single-spindle turning center not specifically itemized in other subcategories is to be classified here.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification into this category relies on confirming the product's function as a numerically controlled single-spindle lathe for metal removal and ensuring it does not meet the criteria for the "multiple spindle" sibling category. Examples could include single-spindle CNC lathes used in job shops for general-purpose turning or those with specific configurations for specialized single-part production.
