8457.10.00.25 - Over 660 mm

This HTS classification covers vertical-spindle machining centers designed for working metal, specifically those where the Y-axis travel exceeds 660 mm. Machining centers, by definition, are multi-functional machines capable of performing a series of operations (drilling, milling, tapping, etc.) on a workpiece without requiring manual repositioning. The "vertical-spindle" designation refers to the orientation of the spindle, and the inclusion of an automatic tool changer signifies their ability to automatically switch between different cutting tools.

The key differentiator for this category, at this level of the tariff schedule, is the physical dimension of the Y-axis travel. It is specifically distinguished from its sibling category, HTS 8457.10.00.15, which covers machines with a Y-axis travel of not over 660 mm. Therefore, any vertical-spindle machining center with an automatic tool changer and a Y-axis travel *greater than* 660 mm falls under this classification.

As this is a leaf node within the HTS database, there are no further subcategories to introduce. Classification at this specific code is definitive based on the machine's configuration and the stated Y-axis travel measurement. Importers should ensure accurate measurement of the Y-axis travel to correctly apply this classification.
