HS Code for Bulk silk thread

Bulk silk thread, specifically yarn other than that spun from silk waste, is classified under HS code 5004.00. This code is part of Chapter 50, which covers silk in various stages of production. The classification is based on the material composition (pure silk or high-percentage silk) and the form in which it is presented. Because the thread is not "put up for retail sale," it is intended for industrial manufacturing, such as weaving or knitting into fabrics. The distinction between 5004.00 and other silk yarns lies in the source of the fiber; 5004.00 excludes yarn derived from silk waste (noil), which is classified under 5005.00. The technical specifications of the yarn, including its twist and ply, do not change its primary classification under 5004.00 as long as it remains an industrial intermediate product. This code is essential for textile manufacturers who import raw silk yarn for large-scale garment or upholstery production.

Products Included

Common Misclassification

Bulk silk thread is often confused with HS code 5005.00, which is specifically for yarn spun from silk waste. It is also frequently misclassified under 5006.00, which covers silk yarn "put up for retail sale." To be in 5006.00, the yarn must meet specific weight and packaging criteria (e.g., on cards, reels, or in balls of a certain weight). If the yarn is on large industrial bobbins, it must remain in 5004.00. Another error is using 5002.00, which is for raw silk that has not yet been spun into yarn.
