HS Code for Silk cocoons

Silk-worm cocoons suitable for reeling are classified under HS code 5001.00. This code is situated at the very beginning of Chapter 50, which covers silk in all its forms, from raw materials to woven fabrics. The classification applies to the protective shells produced by silkworms (Bombyx mori or similar species) that have not yet been processed into yarn. To fall under this specific code, the cocoons must be in a state suitable for the reeling process, which involves unwinding the continuous silk filament. This is a raw material classification based on the biological origin and the initial stage of the textile production chain, following GRI 1.

Products Included

Common Misclassification

Silk cocoons are often confused with HS code 5002.00, which is reserved for raw silk that has already been reeled from the cocoons. Another common error is misclassifying damaged or pierced cocoons under 5003.00. HS code 5003.00 covers silk waste, including cocoons that are unsuitable for reeling because the moth has emerged, breaking the continuous filament. Importers must ensure the cocoons are intact and reelable to maintain the 5001.00 classification.
