5205.23.00 - Exceeding 43 nm but not exceeding 52 nm

This HTS category, 5205.23.00, encompasses single yarns of combed cotton fibers that are not put up for retail sale and contain 85 percent or more by weight of cotton. Specifically, these yarns fall within a defined fineness range, measuring between exceeding 43 but not exceeding 52 nautical miles (nm) per kilogram. This metric refers to the length of yarn that weighs one kilogram, indicating a medium-fine thread suitable for various textile manufacturing purposes.

To distinguish this category from its siblings, the primary differentiating factor is the yarn's fineness, measured in metric number (nm). For instance, yarns finer than 43 nm would be classified under 5205.22.00, while coarser yarns exceeding 52 nm would fall under 5205.24.00. The subsequent sibling categories further refine classifications based on decitex measurements, which offer an alternative way to express yarn fineness.

Within the 5205.23.00 classification, further subdivisions exist to specify the spinning method. The subcategories 5205.23.00.20 and 5205.23.00.90 differentiate between "Ring spun" yarns and "Other" yarns, respectively. Ring spinning is a common method producing durable and uniform yarns, while other spinning techniques may result in different yarn characteristics. This distinction allows for more granular tracking and statistical analysis of cotton yarn production and trade based on manufacturing processes.
