8460.24.00.05 - Used or rebuilt

This HTS classification, 8460.24.00.05, specifically designates "used or rebuilt" numerically controlled grinding machines that fall under the broader category of other grinding machines. These machines are designed for deburring, sharpening, grinding, honing, lapping, polishing, or otherwise finishing metal or cermets using grinding stones, abrasives, or polishing products. The "numerically controlled" aspect signifies that these machines operate using automated pre-programmed commands, allowing for high precision and repeatability in manufacturing processes.

The "Used or rebuilt" descriptor is crucial here, distinguishing these machines from new equipment that would be classified elsewhere. While its sibling category, also under "Other grinding machines," likely encompasses new or un-specified numerically controlled grinding machines, this specific code is reserved for equipment that has undergone prior use and has been subsequently refurbished or rebuilt to a functional state. The focus is on the condition and history of the machinery.

As this is a leaf node, there are no further subcategories. Classification within this code hinges on confirming that the machine is indeed numerically controlled, serves the finishing purposes described in the parent category, and is explicitly stated as being either used or rebuilt. The absence of further subdivisions means that any numerically controlled grinding machine meeting these criteria, regardless of specific grinding medium or minor design variations, will fall under this specific code.
