5509.51.60.00 - Multiple (folded) or cabled yarn (607) 🖩

This HTS category, 5509.51.60.00, covers multiple or cabled yarn spun from synthetic staple fibers, specifically those of polyester. These yarns are not intended for retail sale and are characterized by being twisted together from two or more single strands or by being folded. The "multiple (folded) or cabled" designation is key, distinguishing it from single yarns that comprise only one spun strand.

Within the broader classification of "Other yarn, of polyester staple fibers: Mixed mainly or solely with artificial staple fibers," this category specifically addresses yarns that have undergone a twisting or folding process. This contrasts with its sibling category, 5509.51.30.00, which exclusively covers single yarns of the same polyester and artificial fiber blend. The distinction lies in the construction of the yarn, with this category encompassing yarns that are more complex in their strand arrangement.

As a leaf node in the HTS classification, 5509.51.60.00 does not have further subdivisions. Therefore, classification into this category relies on the definitive presence of multiple or cabled yarn construction when the primary fiber content is polyester staple fiber, mixed mainly or solely with artificial staple fibers, and the product is not put up for retail sale. This ensures accurate categorization for imported and exported goods based on their physical yarn structure and material composition.
