5205.21.00.20 - Ring spun (301) 🖩

This HTS category, 5205.21.00.20, specifically classifies single cotton yarns made from combed fibers. The defining characteristics are that these yarns must contain 85 percent or more by weight of cotton, are not put up for retail sale, and have a specific fineness: their count must not exceed 14 nm (which corresponds to a relatively coarse yarn). The "Ring spun (301)" designation further refines this by specifying the spinning method used, indicating a tightly twisted yarn often produced on a ring spinning machine.

This category is distinguished from its sibling, 5205.21.00.90, which is designated as "Other." While both fall under single yarns of combed cotton fibers not exceeding 14 nm, the 5205.21.00.90 category would capture yarns that, for instance, might be produced by a different spinning method not specifically identified as ring spun, or possess other subtle variations not covered by the "Ring spun (301)" specification.

As this is a leaf node within the HTS, there are no further subcategories to introduce. The classification is complete at this level, identifying a very specific type of cotton yarn based on its fiber composition, yarn structure (single, combed), fineness (count not exceeding 14 nm), presentation (not for retail sale), and spinning method (ring spun).
