8463 - Other machine tools for working metal or cermets, without removing material:

Heading 8463 encompasses machine tools designed for working metal or cermets without the removal of material, distinguishing it from cutting or shaping machines. This category specifically includes apparatus that deform, form, or finish materials through processes such as bending, straightening, forging, pressing, drawing, rolling, or similar metal-forming techniques where the bulk of the material remains intact.

Unlike other headings within Section XVI that might deal with machinery for working with materials by cutting, drilling, or grinding, 8463 focuses on methods that reshape metal and cermets through applied force or pressure. Its siblings are found across various chapters, covering vastly different goods like live animals (Chapter 01) or unrelated machinery types. The key differentiator for 8463 lies in its material deformation purpose and the absence of material removal.

Within 8463, further classification is achieved by the specific metal-forming operation performed. Subheadings like 8463.10.00 cover drawbenches, used for reducing the cross-section of bars, tubes, or wire. 8463.20.00 specifically addresses thread rolling machines, essential for creating threads without cutting. Machines for working wire fall under 8463.30.00, encompassing various wire shaping operations. Finally, 8463.90.00 serves as a residual category for other non-material-removing metalworking machinery not elsewhere specified.
