Last updated: August 2026 dataSpun silk yarn — produced by carding or combing shorter fibers recovered from broken cocoons, pierced cocoons, or other silk processing residues — offers a more economical alternative to reeled filament silk while retaining natural protein fiber properties. Its shorter staple length gives it a slightly matte, textured hand compared to filament silk, making it suitable for specific woven and knitted fabric constructions. The bulk, non-retail packaging requirement separates this product from retail-packed silk yarn, which is classified separately regardless of whether it is spun from waste or not.

Spun silk yarn can be made from several categories of silk waste: broken or pierced cocoons unsuitable for reeling, floss (the outer layers of the cocoon), and combing or carding waste generated during filament processing. The resulting yarn grades — sometimes called schappe (combed) or bourette (carded) — differ in fineness and surface texture depending on the waste source and processing method.
A mill certificate or supplier declaration specifying that the yarn is produced from silk waste rather than from reeled cocoon filament is the standard supporting document. CBP may also accept a process description from the manufacturer. Because the duty rate and heading differ from reeled silk yarn, accurate documentation reduces the risk of reclassification at entry.
