5205.42.00.21 - Compact, exceeding 41 nm (301)

This HTS classification, 5205.42.00.21, pertains to multiple or cabled cotton yarn spun using the ring spinning method, derived from combed cotton fibers. The yarn is characterized by its construction, which involves twisting two or more single yarns together to form a stronger and more substantial thread. Crucially, each single yarn within this cabled structure must fall within the range of exceeding 14 but not exceeding 43 decitex (nm), and the yarn must contain 85 percent or more cotton by weight, not being put up for retail sale.

This specific category is distinguished from its sibling, 5205.42.00.29, "Other," by the explicit parameter of yarn fineness. While both fall under multiple or cabled yarn of combed fibers, this code targets yarns where the individual single strands have a fineness exceeding 14 nm but not exceeding 43 nm. The "Other" category would encompass multiple or cabled yarns of combed fibers that do not meet this specific fineness range or other unstated criteria at this level.

As a leaf node within the HTS, this classification does not have further subcategories. Therefore, practical classification relies on meeting all the specified criteria: being a multiple or cabled yarn, made from combed cotton fibers, spun using the ring spinning method, with individual single yarns measuring between 14 and 43 decitex, and composed of at least 85% cotton. This level of detail ensures precise identification for customs purposes, particularly differentiating from other forms of multiple or cabled cotton yarn.
