5509.69.40.00 - Multiple (folded) or cabled yarn (607) 🖩

This HTS category, 5509.69.40.00, encompasses yarns spun from synthetic staple fibers, specifically those of acrylic or modacrylic staple fibers, which are not intended for retail sale. These yarns are characterized by being either multiple (folded) or cabled. The "multiple" or "cabled" designation refers to yarns constructed from two or more single yarns twisted together to form a single strand, or yarns created by twisting multiple strands together. This structure provides increased strength, durability, and a distinct aesthetic compared to single yarns.

The key distinction from its sibling category, 5509.69.20.00 (Single yarn), lies in the construction of the yarn. While single yarn consists of a single strand of staple fibers twisted together, this category specifically covers yarns that have undergone an additional twisting process to combine multiple single yarns or strands. Furthermore, this classification is restricted to yarns that are mixed mainly or solely with artificial staple fibers.

As a leaf node within the HTS, this category does not have further subcategories. Therefore, classification within 5509.69.40.00 hinges on the precise yarn construction (multiple or cabled), the predominant fiber content (acrylic or modacrylic staple fibers), the presence of artificial staple fibers as a significant component, and the fact that the yarn is not put up for retail sale. Examples include industrial sewing threads for heavy-duty applications, yarns intended for manufacturing carpets, or those for use in technical textiles where enhanced strength is required.
