8461.30.40 - Numerically controlled

This HTS category, 8461.30.40, specifically encompasses numerically controlled broaching machines. These are sophisticated machine tools designed for removing material, typically metal or cermets, through the use of a cutting tool with a series of teeth that move linearly. The "numerically controlled" designation signifies that the machine's operations, including tool movement, workpiece positioning, and cutting parameters, are directed by programmed numerical data. This allows for high precision, repeatability, and complex machining operations that would be difficult or impossible to achieve with manual control.

In contrast to its sibling category, 8461.30.80 (Other), this classification is exclusively for broaching machines that incorporate numerical control systems. The sibling category would include all other types of broaching machines that do not meet the criteria for numerical control, such as manually operated or simpler semi-automatic versions. Therefore, the presence and functionality of a CNC system are the key distinguishing factors for classification under 8461.30.40.

This category is further subdivided to distinguish between broaching machines based on their condition. The subcategory 8461.30.40.20 covers numerically controlled broaching machines that are used or have been rebuilt, implying they are not new. The subcategory 8461.30.40.60, conversely, covers all other numerically controlled broaching machines not falling into the used or rebuilt category, which would typically include new or reconditioned machines. This distinction is crucial for applying specific duty rates and trade regulations.
