8462.11.00 - Closed die forging machines

This HTS category, 8462.11.00, specifically encompasses closed die forging machines. These machines are designed for the hot forming of metal, utilizing dies to shape the workpiece under immense pressure. The process involves placing heated metal between two matching dies that impart the desired shape to the material. This method is distinct from open die forging, where the dies are typically flat or grooved and do not fully enclose the workpiece.

Within the broader heading for machine tools for working metal by forging or die forging, 8462.11.00 distinguishes itself from its sibling category, 8462.19.00 ("Other"). While 8462.19.00 would cover other types of hot forming machines for forging, die forging, and hot hammers that do not exclusively utilize closed dies, 8462.11.00 is narrowly focused on those that operate with closed die sets.

The subcategories further refine the classification of closed die forging machines. 8462.11.00.10 is designated for machines that are either used or rebuilt, indicating a focus on their condition and history. The subsequent "Other" subcategory would then encompass new, unused closed die forging machines that do not fall under the used or rebuilt designation. This hierarchical structure allows for precise tariff application based on the machine's operational status.
