5509.42.00 - Multiple (folded) or cabled yarn

This HTS category, 5509.42.00, encompasses multiple (folded) or cabled yarn composed of synthetic staple fibers. It specifically includes yarn where synthetic staple fibers constitute 85 percent or more of its weight. The key defining characteristic here is the construction of the yarn: it is not a single strand but rather two or more single yarns twisted together (folded) or further combined in a cabled structure. This category excludes yarns that are put up for retail sale.

The primary distinction from its sibling category, 5509.41.00, lies in the yarn structure. While 5509.41.00 covers single yarns of synthetic staple fibers, 5509.42.00 exclusively covers yarns that have undergone a folding or cabling process, resulting in a more complex, multi-strand construction. Both categories, however, fall under the broader heading of other yarn containing 85 percent or more by weight of synthetic staple fibers, not put up for retail sale.

This category is further subdivided into more specific classifications to account for material variations. Subcategory 5509.42.00.10 pertains to yarns made of polyvinyl alcohol (PVA) fibers, while 5509.42.00.90 covers all other folded or cabled yarns meeting the synthetic staple fiber content criteria. These subcategories allow for precise classification based on the specific type of synthetic fiber utilized.
