8461.50.40.10 - Used or rebuilt

This HTS category, 8461.50.40.10, specifically covers numerically controlled sawing or cutting-off machines that are either used or rebuilt. These machines are designed for the precise cutting and shaping of materials, primarily metals and cermets, through automated, programmed operations. The "used or rebuilt" designation is a crucial classification criterion, indicating that the machine has a prior operational history and has undergone refurbishment.

Distinguishing this category from its sibling, 8461.50.40.50 ("Other"), is paramount. While both fall under numerically controlled sawing or cutting-off machines, 8461.50.40.10 is exclusively for items that have been previously in service and are now being resold or reintroduced into operation, regardless of the extent of their rebuilding. The sibling category would encompass new, unused numerically controlled sawing or cutting-off machines.

As a leaf node, this classification does not have further subcategories. Therefore, the classification hinges on the definitive identification of a numerically controlled sawing or cutting-off machine that meets the criteria of being used or rebuilt. Importers and exporters must ensure that documentation clearly reflects the machine's prior operational status to ensure accurate reporting and compliance with customs regulations.
