8459.39.00.40 - Horizontal spindle 🖩

This HTS category, 8459.39.00.40, specifically classifies "Horizontal spindle" boring-milling machines that are not otherwise specified within more granular subheadings. These machines are designed for metalworking operations such as boring, milling, drilling, threading, or tapping, and are characterized by a horizontal spindle. The term "horizontal spindle" is the defining feature for this particular classification.

This subheading distinguishes itself from other "Other" categories at the same level by its precise focus on machines with a horizontal spindle configuration. If a machine, while fitting the general description of an "other" boring-milling machine, possessed a vertical spindle, it would likely fall under a different, more specific subheading. The "Other" classification at this level implies that the machine does not meet the criteria for any more precisely defined types of boring-milling machines within heading 8459.

As this is a leaf node, there are no further subcategories within 8459.39.00.40. Therefore, the classification decision rests on whether a horizontal spindle boring-milling machine is an "other" machine not covered by more specific headings within 8459. Classification within this code relies on a thorough examination of the machine's operational spindle orientation and the absence of specific features that would place it in a more detailed subheading.
