8456.40.10 - For working metal

HTS code 8456.40.10 specifically covers plasma arc cutting machines designed for working metal. These machines utilize a high-temperature ionized gas (plasma) directed at the workpiece to melt and vaporize metal, thereby cutting or shaping it. This category is distinct from other machine tools in heading 8456 that employ different material removal processes.

The distinguishing factor for 8456.40.10 lies in its exclusive focus on the plasma arc process for metalworking. While sibling category 8456.40.90 encompasses other plasma arc machines, this specific code is reserved for those dedicated to metal applications. This ensures a precise classification based on both the operational method and the intended material.

Within this classification, two subcategories exist to further refine the nature of the plasma arc metalworking machinery. 8456.40.10.10 applies to numerically controlled machines, meaning their operation is guided by pre-programmed instructions, offering high precision and automation. Conversely, 8456.40.10.90 covers all other plasma arc metalworking machines that do not fall under the numerically controlled designation.
