5005.00.00.90 - Other (800)

This HTS classification, 5005.00.00.90, covers yarn spun from silk waste that is not put up for retail sale, and which does not meet the specific criteria outlined in its sibling category. Specifically, this "Other" category captures silk waste yarns that contain less than 85 percent by weight of silk or silk waste. The classification hinges on the precise composition of the yarn, differentiating it from yarns where silk or silk waste is the predominant component.

Unlike sibling category 5005.00.00.10, which is dedicated to silk waste yarns composed of 85 percent or more of silk or silk waste, this classification applies to those with a lesser proportion of silk content. The key distinction lies in the quantitative threshold of silk or silk waste by weight. This ensures that yarns with a significant presence of other fibers, even when spun from silk waste, are classified accurately.

As a leaf node in the HTS database, there are no further subcategories under 5005.00.00.90. Therefore, classification within this specific code relies solely on the fulfillment of the criteria described: being yarn spun from silk waste, not presented for retail sale, and containing less than 85 percent by weight of silk or silk waste. Practical examples would include such yarns where other natural or synthetic fibers constitute the majority of the material.
