5206.24.00.00 - Exceeding 52 nm but not exceeding 80 nm (301)

This HTS classification, 5206.24.00.00, pertains to single cotton yarns spun from combed fibers, specifically those where the yarn's fineness falls within a precise range. The critical defining characteristic for this category is that the yarn must have a linear density exceeding 52 tex (decitex) but not exceeding 80 tex (decitex). This measurement, often expressed in nanometers in the provided description, relates directly to the yarn's thickness and weight per unit length. These yarns are not intended for retail sale and contain less than 85 percent cotton by weight, placing them within the broader scope of cotton yarns under Chapter 52.

The distinction between this category and its siblings is solely based on the fineness of the single yarn. Categories 5206.21.00.00, 5206.22.00.00, and 5206.23.00.00 cover yarns that are finer, with maximum tex values of 14, 43, and 52 respectively. Conversely, 5206.25.00.00 classifies single yarns spun from combed fibers that are coarser, exceeding 80 tex. Therefore, precise measurement of the yarn's linear density is paramount for accurate classification within this group.

As a leaf node, HTS 5206.24.00.00 does not have further subdivisions. This means that once a single yarn of combed cotton fibers is determined to fall within the specified tex range of 52 to 80, and meets the other criteria of being a single yarn not put up for retail sale with less than 85% cotton, it is definitively classified here. Examples of such yarns could include those intended for specific industrial textile applications or for further processing into fabrics where a particular thread count and weight are required.
