Heading 5509 — Yarn (other than sewing thread) of synthetic staple fibres, not put up for retail sale
Chapter 55: Man-made staple fibres
Use HS-6 550991 when importing or exporting yarn made from synthetic staple fibers that are primarily mixed with wool or fine animal hair. For example, a shipment of 100 kg of synthetic yarn blended with merino wool for textile manufacturing falls under this code.
This code specifically applies to yarn not intended for retail sale, distinguishing it from HS-6 550992, which covers similar yarns but mixed with other fibers. If your product contains a significant percentage of synthetic fibers combined with wool or fine animal hair, 550991 is likely the correct classification.
Products classified under this code are typically used in the textile industry for making fabrics, garments, and other textile goods. They are not sold directly to consumers but rather to manufacturers who will process them further.
When classifying your yarn, consider the fiber composition and intended use. If your yarn is primarily synthetic and mixed with wool, 550991 is the appropriate choice, while yarns mixed with cotton or other fibers should be classified differently.
