Last updated: July 2026 dataSpun from short-staple silk waste fibers rather than continuous reeled filament, this yarn has a characteristically matte, textured hand that distinguishes it from thrown silk yarn and positions it as a cost-accessible alternative in the woven and knitted fabric supply chain. India leads US imports under this heading, reflecting India's well-developed spun silk industry, with China and Italy also among the top suppliers. The US schedule further subdivides the heading by silk content: yarn containing more than 85% by weight of silk or silk waste (5005000010) is separated from lower-content blends (5005000090), making fiber composition testing a routine compliance step for importers.

The US tariff schedule splits this subheading based on whether the yarn contains more than 85% by weight of silk or silk waste (5005000010) versus lower concentrations (5005000090). Importers should obtain fiber composition test reports from an accredited laboratory or supplier declarations confirming the exact silk content percentage to ensure the correct statistical suffix is declared and to support any textile labeling compliance under the Textile Fiber Products Identification Act.
Spun silk waste yarn (HTS 500500) is made from short fibers carded or combed from silk waste, producing a yarn with a softer, less lustrous appearance sometimes called 'schappe' or 'bourette' silk. Thrown silk yarn (HTS 500400) uses continuous filaments and has higher luster and tensile strength. Fabric manufacturers select between them based on the desired hand, sheen, and price point of the finished textile.
