8458.91.10.60 - Multiple spindle 🖩

This HTS category, 8458.91.10.60, specifically covers vertical turret lathes that are numerically controlled and equipped with multiple spindles. These machines are designed for metalworking operations, primarily turning, facing, and boring, where multiple operations can be performed simultaneously or in rapid succession due to the presence of more than one spindle. The defining characteristic is their vertical turret configuration, which is particularly well-suited for handling large, heavy, or irregularly shaped workpieces.

Within the broader classification of "Other numerically controlled lathes," this subcategory distinguishes itself by the presence of multiple spindles and the vertical turret design. It should be differentiated from other lathes at this level which may be single-spindle, have a horizontal turret, or employ different control mechanisms. The key differentiating factors are the simultaneous turning capabilities offered by multiple spindles and the specific orientation of the tool turret.

As this is a leaf node, there are no further subcategories. Therefore, classification within this specific code relies on accurately identifying the machine as a numerically controlled vertical turret lathe with multiple spindles, fulfilling all these criteria. Importers and exporters should ensure that the imported or exported machinery precisely matches this technical description to ensure correct customs declaration and duty assessment.
