5801.90.20.10 - Containing 85 percent or more by weight of silk or silk waste

This HTS category, 5801.90.20.10, specifically classifies woven pile fabrics and chenille fabrics, other than those of heading 5802 or 5806, that are composed of 85 percent or more by weight of silk or silk waste. This distinction focuses on the primary fiber content, ensuring that articles predominantly made from luxurious silk are appropriately categorized within this specific sub-classification. These fabrics are characterized by their raised surface, achieved through loops of yarn that are either cut or left intact (pile) or by a looped thread construction (chenille).

This classification is distinct from its sibling category, 5801.90.20.90, which covers "Other" woven pile and chenille fabrics. The key differentiator lies in the material composition. While 5801.90.20.10 requires a minimum of 85% silk or silk waste, the "Other" category would encompass woven pile and chenille fabrics made from a different predominant textile material, such as cotton, synthetic fibers, or a blend where silk is not the primary component.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the primary classification criteria for goods falling under 5801.90.20.10 are the fabric construction (woven pile or chenille) and the specific material composition (85% or more silk or silk waste). Importers and exporters should carefully verify the fiber content and construction of their woven pile and chenille fabrics to ensure accurate classification.
