HS Code 5001.00 – Silk; silk-worm cocoons suitable for reeling

HS code 5001.00 is the 6-digit subheading for silk, silk-worm cocoons suitable for reeling. It is used for bombyx mori cocoons, tussah silk cocoons, eri silk cocoons, muga silk cocoons and raw silk cocoons.

What HS 5001.00 covers

This HS code specifically covers raw silk in its earliest stage: silk-worm cocoons that are suitable for reeling. Reeling is the process of unwinding the continuous silk filament from the cocoon. This commodity is the fundamental raw material for the entire silk industry. International trade in silk-worm cocoons is highly concentrated, primarily involving countries with sericulture (silk farming) traditions and those with established silk processing and textile manufacturing industries. Importers are typically silk reeling mills and textile manufacturers seeking high-quality raw material for silk yarn and fabric production. Exporters are sericulture farms and cooperatives. Key considerations include the quality of the cocoons (e.g., size, uniformity, cleanliness), the efficiency of reeling, and the impact of environmental factors on silk-worm health. This trade is crucial for sustaining the global supply chain of natural silk products, from luxury garments to home furnishings.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
