5509.22.00 - Multiple (folded) or cabled yarn

This HTS category, 5509.22.00, specifically covers multiple (folded) or cabled yarns that are not put up for retail sale and are derived from synthetic staple fibers. The defining characteristic here is that these yarns are composed of 85 percent or more by weight of polyester staple fibers. The "multiple (folded) or cabled" aspect signifies that the yarn has been formed by twisting together two or more single yarns, or by plying multiple folded yarns, resulting in a yarn with a greater thickness and often enhanced strength compared to single yarns.

This classification is distinct from its sibling category, 5509.21.00.00, which exclusively covers single yarns of the same polyester staple fiber composition. While both fall under the broader umbrella of polyester staple fiber yarns not intended for retail sale, the key differentiator lies in the construction of the yarn itself – single strand versus multiple strands twisted or cabled together. This distinction is critical for accurate tariff application.

Within this category, further subdivisions exist to refine classification based on the final twist direction. The subcategory 5509.22.00.10 specifically identifies multiple (folded) or cabled yarns where the final twist applied to the plied yarn is in the "Z" direction. All other multiple (folded) or cabled yarns meeting the polyester staple fiber content and not put up for retail sale, but not having a final "Z" twist, fall under the residual subcategory 5509.22.00.90. This granular approach ensures precise identification of the yarn's manufacturing characteristics.
