Chapter 55: Man-made staple fibres
Use HS-4 5508 when importing sewing thread made from man-made staple fibres, like polyester or nylon thread, whether packaged for retail or bulk. For example, if you're bringing in spools of synthetic sewing thread for a textile factory, this heading applies.
Choosing between HS-6 550810 and HS-6 550820 depends on the type of fibres used. If your sewing thread is made from synthetic fibres like nylon or polyester, classify it under 550810. If it's made from artificial fibres like rayon, then use 550820.
Both subheadings include threads that may be sold in retail packaging or in bulk. If you're unsure whether your product is synthetic or artificial, check the material specifications provided by your supplier.
