5206.31.00.00 - Not exceeding 14 nm per single yarn (300)

This HTS category, 5206.31.00.00, specifically classifies multiple (folded) or cabled yarns made from uncombed cotton fibers, where each individual single yarn has a count not exceeding 14 tex (which corresponds to exceeding 14 nanometers per single yarn). These are typically used in industrial applications or for manufacturing purposes where a stronger, thicker yarn is required compared to finer counts. The key defining characteristic for inclusion here is the specific yarn count range for the constituent single yarns.

This classification is distinguished from its sibling categories by its precise limitation on the fineness of the single yarns. For instance, 5206.32.00.00 covers similar multiple or cabled yarns but with single yarns exceeding 14 tex (i.e., finer than 14 nanometers), while 5206.33.00.00 and subsequent categories address increasingly finer single yarn counts. Therefore, the critical differentiator is the measurement of the single yarn's tex (or equivalent nanometer) value, not the number of folds or whether the fibers are combed.

As this is a leaf node in the HTS structure, there are no further subcategories that subdivide this particular classification. Classification into 5206.31.00.00 is final based on the material composition (cotton-based, less than 85% cotton), the yarn structure (multiple or cabled, uncombed fibers), and the specified yarn count of the individual single yarns. If the yarn were intended for retail sale or if it were a single yarn rather than multiple or cabled, it would fall under different HTS headings.
