HS Code for Silk yarn

HS code 500400 is designated for silk yarn that is not spun from silk waste and is not put up for retail sale. This code typically refers to 'thrown silk' or yarn produced by reeling continuous filaments from the cocoon of the silkworm. Unlike waste yarn, which is made from broken or short fibers, yarn under 500400 consists of long, continuous strands that have been twisted together to create strength and luster. The classification process involves examining the manufacturing method; if the yarn is produced by spinning short fibers (even if they are virgin silk), it might be classified elsewhere, but 500400 is the primary home for high-quality, continuous filament silk yarn used in luxury textile production. The exclusion of 'retail sale' packaging is a vital factor, as industrial-sized shipments are the focus of this heading. This code is fundamental for the global trade of raw materials used in high-end fashion and upholstery. To meet the criteria for 500400, the yarn must be in a form suitable for industrial use, such as on large bobbins or in hanks of a certain weight (usually exceeding 125 grams as per Section XI notes). The yarn can be single, multiple (folded), or cabled. It is also important to note that this code excludes 'raw silk' (500200), which has not yet been twisted or 'thrown.' Once the raw silk filaments are twisted to form a yarn, they move from 500200 to 500400. This distinction is critical for customs valuation and compliance, as thrown silk represents a higher level of processing than raw silk. Importers should provide technical data sheets indicating the filament type and the absence of waste fibers to ensure correct classification.

Common Misclassification

Silk yarn is often misclassified as 500500 (Silk waste yarn) if the distinction between filament and spun waste is not clear. It is also confused with 500200 (Raw silk) if the twisting process is minimal. Additionally, if the yarn is packaged for consumer use, it must be classified under 500600 instead of 500400.

FAQ

What is the HS code for silk yarn?

The HS code for silk yarn (not from waste and not for retail) is 500400.

Is raw silk the same as silk yarn?

No, raw silk (500200) is the untwisted filament, while silk yarn (500400) has undergone the 'throwing' or twisting process.
