8459.41.00.90 - Other

This HTS classification, 8459.41.00.90, covers "Other" numerically controlled boring machines. These are specialized machine tools designed for precision metal removal, specifically for enlarging existing holes or creating new ones within a workpiece. Their operation is governed by numerical control systems, allowing for automated and highly accurate execution of boring operations based on programmed instructions. This category is intended for boring machines that do not fit into more specific subcategories within the numerically controlled boring machine group.

Distinguishing this category from its sibling, 8459.41.00.30 ("Vertical"), is crucial. While both are numerically controlled boring machines, this "Other" category encompasses those numerically controlled boring machines that are not primarily configured as vertical units. This implies that the machines classified here may be horizontal boring machines, or possess a configuration that deviates from a purely vertical orientation, or are multi-axis machines where the vertical aspect is not the defining characteristic.

As a leaf node in the HTS structure, 8459.41.00.90 does not have further subcategories. Therefore, classification into this specific code relies on thoroughly excluding the machine from any more detailed or specific classifications within numerically controlled boring machines. Importers must ensure that the machine's primary function is boring, it is numerically controlled, and it does not meet the criteria for any other HTS subcategory, such as the specifically enumerated vertical boring machines.
