8457.20.00.10 - Numerically controlled

This HTS category, 8457.20.00.10, specifically covers **numerically controlled unit construction machines (single station)**. These machines are designed for working metal and are characterized by their single-station configuration, meaning they perform a series of machining operations at one fixed position. The "numerically controlled" aspect signifies that their operations are directed by pre-programmed instructions, typically processed by a computer or other digital control system, allowing for high precision and repeatability in manufacturing processes.

Within the broader classification of "Machining centers, unit construction machines (single station) and multistation transfer machines, for working metal," this code distinguishes itself from its sibling, 8457.20.00.90, which encompasses all *other* unit construction machines not specified as numerically controlled. Therefore, the key differentiator is the presence of advanced numerical control systems for automated operation and precision.

As this is a leaf node, there are no further subcategories. Classification under 8457.20.00.10 is definitive for single-station unit construction machines that utilize numerical control for their metalworking functions. Examples include specialized machines designed for drilling, milling, boring, or tapping operations at a single workpiece location, executed via automated programming.
