8463.20.00 - Thread rolling machines

This HTS category, 8463.20.00, encompasses machines specifically designed for thread rolling. Thread rolling is a cold-forming process used to produce threads on screws, bolts, studs, and other fasteners by deforming the workpiece between two hardened dies. These machines are characterized by their dies or rolling elements that impart the thread form onto the material without cutting or removing metal.

This classification distinguishes thread rolling machines from other metal-working machinery without material removal at the 8463 level. For instance, sibling categories like 8463.10.00 cover drawbenches used for shaping bars, tubes, and profiles, while 8463.30.00 pertains to machines specifically for working wire. Category 8463.90.00 is a residual category for other metal-forming machines not otherwise specified.

Within the thread rolling machine category (8463.20.00), further subdivisions exist to refine classification based on condition and value. Subcategories 8463.20.00.40 specifically address used or rebuilt machines, differentiating them from new equipment. The distinctions between 8463.20.00.60 (valued under $3,025 each) and 8463.20.00.80 (other) are based on the individual unit value of the machine, allowing for more granular tariff treatment of these specialized metalworking tools.
