About yarn spun from silk waste, not put up for retail sale

HS code 5005 covers yarn spun from silk waste, which is a valuable byproduct of the silk production industry. This type of yarn is an important input for a range of textile and apparel products, contributing to the global textile supply chain. The silk waste yarn industry plays a crucial role in maximizing the utilization of silk resources and promoting sustainability within the broader silk industry.

Production process

The production of yarn spun from silk waste typically involves a multi-step process. First, the silk waste, which consists of short, tangled, or damaged silk fibers, is collected and sorted. The waste is then cleaned, carded, and combed to align the fibers. The aligned fibers are then spun into yarn using specialized spinning machinery. The resulting yarn may undergo further processing, such as twisting or plying, to improve its strength and consistency.

Production inputs

The primary input for the production of HS code 5005 yarn is silk waste, which is a byproduct of the 5001 Silk-worm cocoons suitable for reeling and 5002 (Raw silk (not thrown)) industries. In addition to the silk waste, the production process requires specialized spinning machinery, as well as energy, labor, and other supporting resources.

Production outputs

The yarn produced under HS code 5005 is primarily used as an input for the manufacture of various textile and apparel products, such as 5007 Woven fabrics of silk or of silk waste, 6214 Shawls, scarves, mufflers, mantillas, veils and the like, and 6217 Other made up clothing accessories; parts of garments or of clothing accessories, other than those of heading 6212. The silk waste yarn industry contributes to the broader textile and apparel supply chain, providing a sustainable solution for utilizing silk resources.
