5701.90 - Of other textile materials:

This HTS category, 5701.90, specifically covers knotted carpets and other textile floor coverings that are not made of wool or fine animal hair. The defining characteristic of this group is the method of construction: the pile is inserted and knotted by hand or by machine, a process that creates a durable and often intricate floor covering. This distinguishes it from other categories within Chapter 57 that may use different construction techniques or materials.

Unlike its sibling category, 5701.10, which exclusively deals with knotted carpets made from wool or fine animal hair, 5701.90 encompasses those constructed from a broader range of textile materials, such as cotton, synthetic fibers, or other vegetable fibers. The intent is to capture all knotted floor coverings not specifically provided for in the wool category, ensuring comprehensive tariff coverage.

Within this category, further distinctions are made based on the specific method of pile insertion. Subcategory 5701.90.10 applies to those where the pile is inserted and knotted directly during the weaving or knitting process, creating an integrated structure. Subcategory 5701.90.20, conversely, covers all other knotted floor coverings that do not meet the specific criteria for 5701.90.10, but are nonetheless knotted and composed of materials other than wool or fine animal hair.
