8462.19.00.30 - Headers and upsetters, including cold headers

This HTS category, 8462.19.00.30, specifically covers headers and upsetters, including those designed for cold working of metal. These machines are integral to metal forming processes where the material is shaped by striking or pressing it into a desired form, with a particular emphasis on creating heads on fasteners or significantly altering the cross-section of a metal rod or wire. Upsetters are particularly adept at increasing the diameter or adding features to the end of a workpiece.

While this category deals with the broad concept of metal forming by forging, it distinguishes itself from sibling categories primarily by its focus on specific machine types. For instance, 8462.19.00.35 covers mechanical transfer presses, which operate on a different principle of moving the workpiece between multiple stations for sequential operations. This category, however, encompasses machines where the forging or upsetting action is the primary function, irrespective of whether it's performed hot or cold, as long as it falls under the umbrella of headers and upsetters.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification under 8462.19.00.30 hinges on the precise identification of the machinery as a header or upsetter. The key distinguishing factor for inclusion here is the machine's design and intended operation for forming metal through striking or pressing to create specific shapes like heads or to alter dimensions in a manner consistent with upsetting processes.
