5701.90.20.90 - Other

This classification pertains to knotted carpets and other textile floor coverings that are not specifically covered by subheadings for cotton or man-made fibers. These items, while falling under the broader category of knotted textile floor coverings, are composed of textile materials other than cotton or synthetic or artificial fibers. This typically includes floor coverings made from natural fibers such as wool, silk, jute, or other plant-based fibers, provided they are constructed using knotting techniques.

The distinction from sibling categories is crucial. HTS 5701.90.20.20 specifically covers knotted floor coverings of cotton, and HTS 5701.90.20.30 encompasses those made from man-made fibers (synthetic or artificial). Therefore, this "Other" category acts as a residual classification for knotted textile floor coverings where the primary constituent fiber is neither cotton nor a man-made fiber. It is essential to correctly identify the dominant fiber content to ensure accurate classification.

As this is a leaf node, there are no further subdivisions. The classification is finalized at this level, and the goods are classified here based on their knotted construction and their material composition falling outside the specific enumerations for cotton and man-made fibers. Practical classification will rely on examining the material composition of the knotted textile floor covering.
