5703.90.00.00 - Of other textile materials

HTS Code 5703.90.00.00 encompasses carpets and other textile floor coverings, including artificial turf, that are tufted and manufactured from textile materials *not specifically enumerated* in the preceding subheadings of heading 5703. This category serves as a residual classification for tufted floor coverings where the primary textile material does not fall under wool, fine animal hair, nylon, or other polyamides. Examples include tufted floor coverings made from cotton, silk, other synthetic fibers (such as polyester or acrylic), or blends of these materials where the dominant fiber does not align with the more specific categories.

This heading is distinguished from its siblings, such as 5703.10 (of wool or fine animal hair) and the subcategories for nylon or other polyamides, by the specific composition of the textile materials used. If a tufted carpet or floor covering is predominantly made of wool or fine animal hair, it would be classified under 5703.10. Similarly, if the primary textile component is nylon or another polyamide, it would fall into a different, more specific category within heading 5703. This subheading, 5703.90.00.00, is therefore reserved for those tufted floor coverings where the distinguishing textile material is neither wool, fine animal hair, nor nylon/polyamide.

As HTS Code 5703.90.00.00 is a leaf node, there are no further subcategories to introduce. Classification at this level hinges on the accurate identification of the predominant textile material used in the tufted floor covering, ensuring it does not meet the criteria for the more specific material classifications found in the preceding subheadings of heading 5703. The "other textile materials" clause is critical for ensuring all tufted floor coverings are correctly classified within the broader framework of heading 5703.
