HS Code for Untwisted silk

Untwisted silk, technically referred to as raw silk, is classified under HS code 5002.00 because it represents the primary state of silk filaments after they have been reeled from the cocoon but before they have undergone the 'throwing' process. In the context of the Harmonized System, 'raw silk' is defined as silk that has not been twisted or doubled to form a yarn. The filaments are held together solely by the natural gum, known as sericin, which is present in the silk as it is produced by the silkworm. This classification is strictly reserved for silk in its most basic form, typically presented in hanks or skeins of varying lengths. The absence of a 'twist' is the defining characteristic that distinguishes this heading from subsequent silk yarn headings. Even if the silk has been cleaned or degummed, as long as it has not been twisted, it remains within this classification. This code is essential for the global trade of silk as a raw commodity before it enters the textile manufacturing chain for spinning or weaving.

Products Included

Common Misclassification

The most frequent misclassification occurs with HS code 5004.00, which covers silk yarn. The distinction lies entirely in the 'throwing' or twisting process; once the silk filaments are twisted together to increase strength and durability, they must be moved to 5004.00. Another common error involves HS code 5003.00, which is designated for silk waste. Silk waste includes cocoons unsuitable for reeling, pulled or garnetted rags, and noils. If the silk is not a continuous filament reeled from a cocoon, it belongs in the waste category rather than 5002.00.

FAQ

What is the HS code for untwisted silk?

The HS code for untwisted silk, also known as raw silk (not thrown), is 5002.00.

What is the difference between raw silk and thrown silk?

Raw silk (5002.00) consists of filaments reeled together without any twist, while thrown silk (5004.00) has been twisted or doubled to create a yarn suitable for textile production.
