Chapter 55: Man-made staple fibres
Use HS-6 550999 when importing or exporting yarn made from synthetic staple fibres, particularly when it is mixed with other non-cotton or non-wool fibres and not packaged for retail. For example, a shipment of polyester yarn mixed with acrylic fibres would fall under this code.
This code is specific to yarns that are not intended for retail sale, distinguishing it from HS-6 550910, which covers sewing thread made from synthetic staple fibres. If your product is a sewing thread, you would need to classify it differently.
In contrast to HS-6 550990, which includes other synthetic yarns not elsewhere classified, HS-6 550999 focuses on yarns mixed with specific fibres but still not for retail. This can include blends that are primarily synthetic but have small amounts of other fibres.
Understanding the nuances between these codes is crucial for accurate customs declarations and avoiding delays. Always check the specific composition of your yarn to ensure it aligns with the correct classification.
