Knotted rugs and carpets made from textile materials other than wool or fine animal hair — including cotton, silk, synthetic, and vegetable fibers — occupy a distinct classification from their wool counterparts, a distinction that directly affects applicable duty rates and quota treatment. The hand-knotting construction method is a key determinant at customs, as it separates these articles from tufted or woven floor coverings even when fiber content is similar. Importers should be aware that country of origin marking and fiber content labeling under the Textile Fiber Products Identification Act apply at entry. Classification can hinge on precise fiber composition, so documentation from the manufacturer specifying material content is essential.
