6304.99 - Not knitted or crocheted, of other textile materials:

This HTS category, 6304.99, encompasses a broad range of "other furnishing articles" that are not knitted or crocheted and are made from textile materials not specifically covered by previous subheadings within 6304. The "other textile materials" designation is key, indicating that goods classified here are distinct from those made of cotton (6304.92) or synthetic fibers (6304.93). This includes furnishing articles like curtains, bedspreads, pillowcases (if not part of sets under 6304.91), and table linen, provided they are not knitted or crocheted and are not primarily made of cotton or synthetic fibers.

The primary distinction of 6304.99 from its sibling categories lies in its residual nature for textile materials other than cotton and synthetic fibers, and the exclusion of knitted or crocheted items. While 6304.91 covers knitted or crocheted items, and 6304.92 and 6304.93 specifically enumerate cotton and synthetic fibers respectively, 6304.99 acts as a catch-all for furnishing articles made from other natural fibers (like silk, wool, linen, etc.) or blends where cotton or synthetic fibers are not the predominant component.

Within this category, further distinctions are made. The subcategory "Wall hangings of wool or fine animal hair" isolates specific items of significant value and distinct material composition. The subsequent "Other" subdivision accounts for all remaining furnishing articles not knitted or crocheted and made from textile materials not covered elsewhere in this heading, ensuring comprehensive coverage of made-up textile furnishings.
