5509.12.00.00 - Multiple (folded) or cabled yarn (604)

This HTS category, 5509.12.00.00, encompasses yarn composed of synthetic staple fibers, specifically those of nylon or other polyamides, where these fibers constitute 85 percent or more of the total weight. The yarn in this classification is characterized by being multiple (folded) or cabled, meaning individual strands have been twisted together to form a stronger, thicker yarn. Importantly, these yarns are not packaged for retail sale, indicating they are intended for industrial or manufacturing use.

The primary distinction between this category and its sibling, 5509.11.00.00, lies in the construction of the yarn. While both are un-cabled, multi-component yarns containing at least 85% nylon or polyamide staple fibers, this category specifically covers yarns that have undergone further twisting to create a folded or cabled structure. Single yarns, by contrast, consist of a single strand of spun fibers.

As this is a leaf node in the HTS classification structure, there are no further subcategories under 5509.12.00.00. Therefore, classification within this code is determined by the material composition (nylon or other polyamide staple fibers, 85% or more by weight), the yarn construction (multiple or cabled), and the packaging (not for retail sale). Examples of goods falling here would include industrial sewing threads, yarns for weaving or knitting into durable fabrics, or components for technical textiles that require the strength and durability provided by cabled nylon yarns.
