5206.21.00.00 - Not exceeding 14 nm (301) 🖩

This HTS classification, 5206.21.00.00, specifically covers single yarn made from combed cotton fibers, where the yarn's "number" does not exceed 14 nanometers (nm). The "number" of yarn is a measure of its fineness, with a higher number indicating a finer yarn. Therefore, this category encompasses relatively coarse single cotton yarns composed of combed fibers, intended for industrial or manufacturing purposes and not packaged for retail sale.

The distinction of this category from its siblings lies solely in the fineness of the yarn. For instance, sibling category 5206.22.00.00 covers single combed cotton yarns with a number exceeding 14 nm but not exceeding 43 nm, representing a finer yarn. As the yarn becomes finer, it falls into subsequent sibling categories with progressively higher nm ranges. This specific classification, 5206.21.00.00, is reserved for those single combed cotton yarns that are at the coarsest end of this particular grouping.

As this is a leaf node in the HTS database, there are no further subcategories under 5206.21.00.00. This signifies that once a single yarn of combed cotton fibers meets the criterion of not exceeding 14 nm in number, it is definitively classified here, assuming all other conditions of the parent categories (e.g., containing less than 85% cotton, not being sewing thread, and not being put up for retail sale) are met. The classification is determined by the yarn's composition, fiber preparation (combed), single ply structure, and its specific fineness measurement.
