5205.21.00.90 - Other (301)

This HTS category, 5205.21.00.90, covers single yarns of combed cotton fibers not exceeding 14 nm in linear density. These yarns must contain 85 percent or more by weight of cotton and are not presented for retail sale. The "Other" designation at this sub-heading level indicates that while the yarn meets the criteria of being a single yarn of combed cotton fibers with a specific linear density, it is not further specified by its spinning method, such as ring-spun or open-end spun.

To classify goods within this category, it is crucial to confirm the yarn's composition, ensuring it is predominantly cotton, and to determine its linear density. The distinction from sibling categories, such as 5205.21.00.20 (ring-spun), relies on identifying the specific spinning technique employed. If a yarn is not identified as ring-spun and meets all other criteria, it will fall under this "Other" classification.

As this is a leaf node, there are no further subdivisions. Classification is complete once the criteria for single yarn of combed cotton fibers, not exceeding 14 nm, containing 85% or more cotton by weight, and not put up for retail sale, are met, and its spinning method is not specifically identified as ring-spun.
