8456.30.10.70 - Other

This HTS category, 8456.30.10.70, encompasses "Other" machine tools operated by electro-discharge processes for working metal, excluding those specifically classified as numerically controlled. These machines utilize electro-discharge machining (EDM) principles to remove material from metal workpieces through controlled electrical sparks. Examples include manual EDM machines or those with automated features that do not meet the strict definition of numerical control for all aspects of their operation.

Distinguishing this category from its sibling, 8456.30.10.50, is the absence of comprehensive numerical control. While this category may include some automated functions, the primary differentiator is that the machine's operational parameters and movements are not fully dictated by a pre-programmed numerical control system in the same way as its numerically controlled counterpart. This often translates to simpler operational interfaces or less complex integration of automation.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification within 8456.30.10.70 hinges on identifying machines that perform metalworking via electro-discharge processes and do not fall under the numerically controlled classification. The key determining factors are the method of material removal (electro-discharge) and the specific level of automation and control integrated into the machine's design and operation.
