8305.90 - Other, including parts:

This HTS category, 8305.90, encompasses a variety of miscellaneous articles of base metal used in office or organizational contexts that are not specifically classified under more precise headings. It includes items such as indexing tags, letter corners, and other similar office articles made from base metals. Crucially, this heading also extends to parts of any of the articles described within the broader 8305 chapter.

To distinguish this category from its siblings, note that 8305.10.00 specifically covers fittings for loose-leaf binders or files, while 8305.20.00.00 is dedicated to staples in strips. HTS 8305.90, therefore, acts as a residual category for other base metal office articles that do not fit these more defined descriptions, focusing on articles designed for organizing or fastening papers and documents, and their constituent components.

The subcategories within 8305.90 provide further clarification. The primary subdivision, 8305.90.30, isolates paper clips and their respective parts, recognizing their commonality and distinct function. The remaining items, along with their parts, fall under the broader classification of 8305.90.60.00, signifying "Other" base metal office articles not otherwise specified within this group.
