8457.30.00.10 - Numerically controlled

HTS code 8457.30.00.10 specifically covers multistation transfer machines that are numerically controlled. These machines are designed for automated machining operations, featuring multiple workstations where different machining processes can occur sequentially or simultaneously on a workpiece as it moves from one station to the next. The defining characteristic of this subcategory is the integration of numerical control systems, which use programmed instructions to dictate the machine's movements, operations, and sequences, thereby enabling high precision and repeatability in mass production environments.

This category is distinguished from its sibling, 8457.30.00.90 "Other," by the explicit requirement of numerical control. While both fall under multistation transfer machines, the "Other" category would encompass similar machines that operate through less automated or non-numerical control mechanisms, such as manual operation, simpler programmable logic controllers without full numerical capability, or older mechanical control systems. Therefore, the presence and function of a numerically controlled system are the critical differentiator for classification under 8457.30.00.10.

As this is a leaf node, there are no further subcategories. Classification at this level is determined by the machine's design as a multistation transfer type and its operational characteristic of being numerically controlled. Examples of goods classified here would include complex automated production lines for manufacturing automotive parts or intricate mechanical components, where a series of machining operations are performed on a workpiece as it advances through a series of dedicated stations, all governed by computer-driven numerical control.
