8456.30.10.50 - Numerically controlled

HTS Code 8456.30.10.50 specifically classifies numerically controlled machine tools designed for working metal through electro-discharge processes. These machines utilize electrical erosion to remove material with high precision, making them suitable for intricate machining operations. The "numerically controlled" aspect signifies that the machine's movements and operations are directed by computer programming, allowing for automated and repeatable production of complex metal parts.

This category is distinguished from its sibling, 8456.30.10.70 ("Other"), by its explicit designation as "numerically controlled." While both fall under electro-discharge machines for working metal, the .50 code focuses on advanced, automated systems. The "Other" category would encompass electro-discharge machines for working metal that are not numerically controlled, likely operating through manual controls or less sophisticated automation.

As this is a leaf node, there are no further subcategories under 8456.30.10.50. Therefore, the focus for classification remains on confirming that the subject merchandise is indeed a machine tool that works metal via electro-discharge processes and is operated under numerical control. Examples of such machinery include numerically controlled wire electrical discharge machines (EDM) and numerically controlled ram EDM machines used in tool and die making, precision component manufacturing, and other industries requiring high-accuracy metal removal.
