8459.39.00 - Other

This HTS category, 8459.39.00, covers "other" boring-milling machines that are not numerically controlled. These machines are designed for metal removal operations, specifically boring and milling, and do not fall under the more specific numerically controlled classification. They are characterized by their mechanical control systems and are utilized for precise machining of workpieces.

Distinguishing this category from its sibling, 8459.31.00, is crucial. While both fall under "Other boring-milling machines," 8459.31.00 is exclusively for those machines equipped with numerically controlled (NC) systems, allowing for automated, pre-programmed operations. The machines classified under 8459.39.00 operate via manual controls, traditional mechanical systems, or other non-NC automation, requiring more direct operator intervention for setting parameters and guiding the machining process.

The subcategories within 8459.39.00 further refine the classification based on specific characteristics. The distinction between "Used or rebuilt" (8459.39.00.10) and other machines is based on the machine's condition. Furthermore, the distinction for "Other, valued under $3,025 each" indicates a de minimis value threshold, separating less expensive units from higher-value ones within the non-NC boring-milling machine category. The final "Other" subcategory, when present, signifies items not meeting these specific value or condition criteria.
