6001.99.10.00 - Containing 85 percent or more by weight of silk or silk waste

This HTS category, 6001.99.10.00, specifically covers knitted or crocheted pile fabrics that are not composed primarily of silk or silk waste. The key characteristic defining this classification is that the fabric must contain 85 percent or more by weight of silk or silk waste. This means the fabric will exhibit the distinct properties associated with silk, such as its lustrous sheen, softness, and drape, in a knitted or crocheted construction.

This classification is distinguished from its sibling category, 6001.99.90.00, which is designated for "Other" knitted or crocheted pile fabrics. While both fall under the broader umbrella of "Of other textile materials" within the "Other" category for knitted or crocheted pile fabrics, 6001.99.10.00 is for those predominantly made of silk. The sibling category would therefore encompass pile fabrics meeting the general criteria but composed of textile materials other than silk or silk waste, or with a silk content below the 85 percent threshold.

As this is a leaf node in the HTS database, there are no further subcategories. Classification at this level requires a definitive determination of the primary textile material. Therefore, for accurate classification under 6001.99.10.00, the importer or exporter must be able to substantiate, typically through laboratory analysis or supplier documentation, that the knitted or crocheted pile fabric in question is comprised of 85 percent or more silk or silk waste by weight. This ensures that goods are correctly identified and duties are applied accordingly.
