8458.99.50.90 - Other

This HTS category, 8458.99.50.90, encompasses "Other" lathes for removing metal. It serves as a residual classification for turning machines that do not fall into the more specific subcategories of used or rebuilt lathes (8458.99.50.30) or other lathes valued under $3,025 each (8458.99.50.60). Therefore, this category applies to new lathes for metal removal that are not covered by the explicit value-based exclusion.

The defining characteristic for classification under 8458.99.50.90 is that the lathe is designed for metal removal through turning, and it does not meet the criteria for the sibling categories. This means it is not explicitly designated as "used or rebuilt" and its value exceeds the threshold specified for the other "other" subcategory. The primary function remains the shaping of metal workpieces by rotating them against a cutting tool.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification decisions within this branch of Chapter 84 will therefore hinge on distinguishing between new, rebuilt, and value-tiered lathes to ensure accurate tariff treatment.
