5005.00.00 - Yarn spun from silk waste, not put up for retail sale

This HTS category, 5005.00.00, specifically addresses yarn spun from silk waste that is not intended for direct sale to consumers in pre-packaged retail formats. It encompasses yarns derived from residual silk fibers or fragments left over from the processing of raw silk or other silk products. The key defining characteristic is the origin of the material – it must be silk waste.

When classifying within Section XI, it is crucial to distinguish this category from other silk-related headings. While Chapter 50 broadly covers silk and silk waste, this particular heading focuses on a specific form of processed silk waste: spun yarn. Other headings within Chapter 50 might cover raw silk, silk cocoons suitable for reeling, or silk waste in its unspun state. Furthermore, this category is distinct from headings for other types of yarn that may originate from different natural or synthetic fibers, or even from other forms of recycled textile materials.

Within HTS 5005.00.00, two subcategories exist to further refine the classification. These subdivisions are based on the quantitative composition of the yarn. The primary subcategory, 5005.00.00.10, applies to yarns where silk or silk waste constitutes 85 percent or more of the total weight. The residual subcategory, 5005.00.00.90, covers all other yarns spun from silk waste where the silk or silk waste content falls below this 85 percent threshold, reflecting a blend with other materials.
