HS Code for Silk waste yarn

Silk waste yarn is classified under HS code 500500, which specifically covers yarn spun from silk waste that is not put up for retail sale. This classification is distinct from virgin silk yarn because the fibers used are derived from the by-products of the reeling and spinning processes. There are two primary types of yarn included here: schappe silk yarn, which is made from high-quality waste that has been degummed and combed, and bourette silk yarn, which is made from shorter fibers or noils. The 'not put up for retail sale' provision is a technical requirement defined in the Section XI notes of the Harmonized System. Generally, this means the yarn is imported in bulk forms like large cones, tubes, or hanks intended for industrial weaving or knitting rather than small balls or skeins for consumer use. If the yarn were packaged for retail, it would move to heading 5006. Accurate classification requires verifying the fiber source and the packaging specifications. The production of silk waste yarn involves spinning short-staple fibers, which gives the yarn a different texture and strength profile compared to continuous filament silk. This yarn is often used in the production of heavier fabrics, upholstery, or casual apparel. Customs officials may require documentation proving the yarn was spun from waste (noils or schappe) rather than reeled from whole cocoons. The distinction is important because waste yarn often carries different tariff rates and is subject to different trade quotas in certain jurisdictions. Furthermore, the yarn must consist of at least 85% silk by weight to be classified here if it is a blend, otherwise, it may fall under mixed textile headings in Chapter 55.

Common Misclassification

The most common error is confusing 500500 with 500400 (Silk yarn other than waste). Another frequent mistake is using 500600, which is the correct code if the silk waste yarn is packaged for retail sale (e.g., in small skeins for hand-knitting). Importers also sometimes use 560500 if the yarn is metallized, which is incorrect.
