Harmonized System Classification Hierarchy
Complete Tariff Product Description
What is classified under HS Code 5001.00.00?
HS Code 5001.00.00 covers silkworm cocoons suitable for reeling. In commercial practice these goods are traded as Raw Silk Fiber made of Natural Silk, and buyers, factories and customs brokers most often refer to them as silkworm cocoons, raw silk, sericulture.
The code is read level by level: Section XI (Textiles and Textile Articles) narrows to Chapter 50 (Silk), then Heading 5001 (Silkworm cocoons suitable for reeling) and Subheading 5001.00 (Silkworm cocoons suitable for reeling), ending at the 8-digit tariff line 5001.00.00. The first six digits follow the WCO international standard and stay the same in every country; the final two digits are the national subdivision used for duty assessment and trade statistics.
- Classification is decided by the heading text and the material and construction it names — here, Natural Silk and Raw Silk Fiber.
- If a shipment mixes this product with other textile articles, each item is classified under its own heading; goods put up in sets follow the essential-character rule (GIR 3).
- When the same product exists in several materials, the material named in this code (Natural Silk) is the one that must appear on the invoice and packing list.
How to declare HS Code 5001.00.00
- Commercial invoice: print 5001.00.00 next to the item description (Raw Silk Fiber) with the material composition (Natural Silk) matching the code text exactly.
- Packing list: keep quantities, net and gross weights and carton counts consistent with the invoice line for this code.
- Certificate of Origin & Bill of Lading: repeat the same code so bank document checkers under an L/C and customs officers see one consistent classification across all documents.
- Before shipment: verify the code against the destination country's current tariff schedule — duty rates, restrictions and required certificates are set nationally, not by the HS code itself. Note for this code: Raw silk cocoons typically qualify for duty-free entry in major textile manufacturing zones for value addition.
