8466.93.96.00 - Parts and accessories of machine tools of subheadings 8456.11, 8456.12, 8456.30, 8457.10, 8458.91, 8459.21, 8459.61 and 8461.50, of a kind used solely or principally for the manufacture of printed circuits, printed circuit assemblies, parts of heading 8517 or parts of automatic data processing machines

This HTS classification, 8466.93.96.00, specifically covers parts and accessories designed for use with certain machine tools. These machines include those for drilling, boring, milling, and grinding, as detailed in subheadings 8456.11, 8456.12, 8456.30, 8457.10, 8458.91, 8459.21, 8459.61, and 8461.50. Crucially, the primary function of these parts and accessories must be for the manufacture of printed circuits, printed circuit assemblies, or parts of automatic data processing machines or heading 8517.

Distinguishing this category from its sibling, 8466.93.98, lies in the specific end-use requirement. While 8466.93.98 encompasses "other" parts and accessories for machines of headings 8456 to 8461 that do not meet the specific manufacturing criteria of 8466.93.96.00, this classification is narrowly focused on those essential for creating electronic components and assemblies. Therefore, the intended application and the goods being manufactured are the key differentiating factors.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 8466.93.96.00 hinges on meeting all the criteria outlined in its description: the type of parent machine tool, the specific manufacturing purpose, and the electronic products being created. Examples of items that would fall under this code include specialized tooling, fixtures, or workholding devices explicitly designed for automated assembly lines producing printed circuit boards or their components.
