HS-6 · Subheading
Yarn; (not sewing thread), single, of synthetic staple fibres, containing 85% or more by weight of polyester, not put up for retail sale
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 550921 when importing or exporting single yarn made from synthetic staple fibers, specifically those containing 85% or more polyester. For example, a shipment of 1,000 kg of unspooled polyester yarn intended for textile manufacturing falls under this code.
This code specifically targets yarn that is not packaged for retail sale, distinguishing it from HS-6 550922, which covers similar yarns but with different polyester content or retail packaging. If your product is a retail-ready spool of polyester yarn, you would not use this code.
Yarn classified under HS-6 550921 is typically used in industrial applications, such as weaving and knitting, rather than for direct consumer sales. This makes it essential for manufacturers looking to source materials for production.
When determining the correct classification, consider the yarn's composition and intended use. For instance, if the yarn contains less than 85% polyester, you would need to look at other classifications under the same heading.
