5509.22.00.10 - Multiple (folded), with a final "Z" twist (200) 🖩

This HTS classification, 5509.22.00.10, specifically covers multiple (folded) yarns made from synthetic staple fibers, not intended for retail sale. The defining characteristic of this category is the presence of a final "Z" twist applied to the yarn, indicating a specific yarn construction method. These yarns must contain 85 percent or more by weight of polyester staple fibers. The "multiple (folded)" designation means that two or more single yarns have been twisted together to form a more substantial yarn structure.

This subcategory is distinguished from its sibling, 5509.22.00.90, by the presence of the "Z" twist. While both classify multiple (folded) yarns of polyester staple fibers (containing 85% or more polyester), the "-10" code is for those with this specific final twist construction. The absence of further subcategories indicates that this is a terminal classification node, meaning it represents a precise grouping of goods without further breakdown at this level. Therefore, classification within this code relies on confirming the yarn's construction as multiple (folded), its polyester staple fiber content, and the specific application of a final "Z" twist.
