HS Code for Silkworm cocoons

Silkworm cocoons are classified under HS code 5001.00. This is a primary raw material code within the silk chapter of the Harmonized System. It specifically covers cocoons that are suitable for reeling, which is the process of unwinding the silk filament. Because these are considered the most basic form of silk production, they are placed at the very beginning of Chapter 50. The classification applies to the cocoons in their natural state or after they have been dried to kill the pupa, provided the silk filament remains intact and reelable for the production of raw silk.

Common Misclassification

A common misclassification is HS code 5003.00, which covers silk waste. If the cocoons are damaged, perforated (where the moth has emerged), or otherwise unsuitable for reeling, they are considered waste and must be moved to 5003. Additionally, some importers mistakenly look at Chapter 5 (Products of animal origin), but Note 1 to Chapter 5 excludes silk and silk waste, mandating that all silkworm products for textile use remain in Chapter 50.
