8463.20.00.40 - Used or rebuilt

This HTS classification, 8463.20.00.40, specifically covers used or rebuilt thread rolling machines. These machines are designed for the metalworking industry, utilizing a process that deforms metal rather than removing it, to create threads on fasteners or other components. The "used or rebuilt" designation is the primary distinguishing factor for this particular code, indicating that the machine has been previously employed in manufacturing and has undergone refurbishment to restore its operational capacity.

This category differentiates itself from its siblings, 8463.20.00.60 (Other, valued under $3,025 each) and 8463.20.00.80 (Other), by its condition. While those sibling categories may also encompass thread rolling machines, they are defined by their monetary value or lack of specific designation, respectively. Therefore, a machine must be explicitly identified as "used or rebuilt" to fall under 8463.20.00.40.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is conclusive based on the product type (thread rolling machine) and its condition (used or rebuilt).
