Chinese Bombyx Mori Raw Silk
Raw silk filament reeled from cocoons of the Bombyx mori silkworm, sourced from mulberry plantations in China. This unthrown silk retains its natural gum (sericin) and has not undergone any twisting or processing beyond reeling. It falls under HTS 5002.00.00.00 as raw silk noil-free and not thrown, representing the primary form of silk for further textile processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing silk noil or waste
Silk noil (short fibers from reeling waste) or unthrown silk noil classifies under 5003 as raw silk waste, not pure filament.
If thrown or twisted into yarn
Once silk filaments are twisted together, it becomes thrown silk yarn under 5004, no longer raw silk.
If from wild silkworms like tussah
Raw silk from non-Bombyx mori silkworms (e.g., Antheraea pernyi) falls under Chapter 51 as silk waste or noil from wild varieties.

Import Tips & Compliance
• Obtain a certificate of origin specifying mulberry-fed Bombyx mori silk to verify authenticity; ensure no degumming has occurred as that shifts classification; declare exact length/weight per bale to avoid valuation disputes
