8460.22.00.40 - Used or rebuilt 🖩

This HTS category, 8460.22.00.40, specifically covers used or rebuilt centerless grinding machines that are numerically controlled. These machines are designed for the precise finishing of metal or cermet parts by utilizing grinding stones, abrasive wheels, or polishing products without the need for a workpiece holding fixture. The "numerically controlled" aspect signifies that these machines are operated by programmed computer commands, allowing for high degrees of automation and accuracy in the grinding process. This classification applies only to machines that have been previously used and subsequently rebuilt or refurbished, signifying they are not new units.

The distinguishing factor for this category from its sibling, 8460.22.00.80 ("Other"), lies in the explicit condition of the machine. While the sibling category would encompass new centerless grinding machines, this specific code targets only those that have undergone a restoration process after prior use. The primary function remains centerless grinding via numerical control, but the "used or rebuilt" status is the critical determinant for classification under this heading.

As this is a leaf node, there are no further subcategories. Classification within 8460.22.00.40 is finalized once it is confirmed that the machine is a numerically controlled centerless grinding machine and that it is in a used or rebuilt condition. The focus for customs purposes will be on verifying the functional capabilities of the machine and ensuring that the description accurately reflects its post-rebuild state.
