Heading 5205 — Cotton yarn (other than sewing thread), containing 85% or more by weight of cotton, not put up for retail sale
Chapter 52: Cotton
Use HS-6 520521 when importing or exporting cotton yarn that contains 85% or more cotton by weight, specifically in single strands of combed fibers. For example, a shipment of 1000 kg of this yarn, used for textile manufacturing, would fall under this code.
This code is distinct from HS-6 520522, which covers cotton yarn of similar composition but with a finer measurement. If your product measures less than 714.29 decitex or exceeds 14 metric number, you should consider that classification instead.
The 520521 line specifically addresses cotton yarn not intended for retail sale, meaning it is typically sold in bulk to manufacturers rather than individual consumers. This is important for compliance and tariff purposes.
When classifying your product, ensure it meets the criteria of being single yarn, made from combed fibers, and having the specified cotton content. Misclassification can lead to delays and additional costs.
