5702.91 - Of wool or fine animal hair:

This HTS category, 5702.91, specifically covers woven carpets and other textile floor coverings that are made up (finished articles) and are not of pile construction. The defining characteristic of this group is that the material used is either wool or fine animal hair. These are typically handwoven rugs such as "Kelem," "Schumacks," and "Karamanie," where the pattern is integrated into the weaving process rather than being applied afterward.

The distinction from its sibling categories lies solely in the material composition. Category 5702.92 would apply to similar made-up, non-pile woven floor coverings constructed from man-made textile materials, while 5702.99 encompasses those made from other textile materials not specifically covered by the preceding headings. Therefore, the classification here hinges on the precise identification of wool or fine animal hair as the primary constituent fiber.

Within this category, further subdivision is made based on the method of manufacture. The subcategory under 5702.91.40.00, described as "Other," pertains to these wool or fine animal hair floor coverings that are woven but not on a power-driven loom. This distinguishes handwoven products from those produced by mechanized means, even though both fall under the broader umbrella of non-pile woven construction made from these specific animal fibers.
