5206.13.00.00 - Exceeding 43 nm but not exceeding 52 nm (300)

This HTS category, 5206.13.00.00, specifically classifies single yarns of uncombed cotton fibers that are not intended for retail sale and contain less than 85% cotton by weight. The defining characteristic of this yarn is its linear density, measured in tex, which falls within a specific range: exceeding 43 but not exceeding 52 nanometers (nm) per single yarn. This precise measurement is crucial for differentiating it from other yarn classifications.

This category is distinguished from its siblings primarily by the specified range of yarn fineness. For instance, 5206.11.00.00 covers yarns not exceeding 14 nm, while 5206.12.00.00 encompasses yarns between 14 nm and 43 nm. Conversely, 5206.14.00.00 and 5206.15.00.00 cover yarns that are coarser, exceeding 52 nm, up to 80 nm and over 80 nm respectively. Therefore, the exclusive criterion for this classification is the yarn's fineness falling within the 43 nm to 52 nm bracket.

As a leaf node, this category does not have further subcategories. All relevant classification criteria, including the material composition (less than 85% cotton), the state of the fibers (uncombed), the yarn construction (single yarn), its intended use (not put up for retail sale), and its specific linear density (exceeding 43 nm but not exceeding 52 nm), are fully defined at this level. Importers and exporters should verify these characteristics to ensure accurate classification.
