8458.19.00.70 - Multiple spindle

This HTS classification covers automatic bar and/or chucking machines that are designed for metal removal through turning operations, specifically those featuring multiple spindles. These machines are characterized by their ability to perform multiple machining operations simultaneously on different workpieces or sequentially on the same workpiece using several spindles, thereby increasing efficiency and productivity in metalworking. The "multiple spindle" designation is the key identifier for goods falling under this code.

This category is distinguished from its sibling, HTS 8458.19.00.50, which covers single-spindle automatic bar and/or chucking machines. While both are automatic lathes for metal removal, the fundamental difference lies in the number of spindles. Machines classified here will have two or more spindles, whereas those in the sibling category will have only one. This distinction is crucial for accurate customs declaration and tariff application.

As this is a leaf node within the HTS structure, there are no further subcategories under 8458.19.00.70. Therefore, classification within this code relies solely on identifying an automatic bar and/or chucking lathe for metal removal that possesses multiple spindles. Importers and exporters should ensure that the operational characteristics and the physical presence of multiple spindles are clearly documented to support this classification.
