5205.24.00 - Exceeding 52 nm but not exceeding 80 nm

This HTS code, 5205.24.00, classifies single cotton yarns spun from combed fibers that fall within a specific fineness range. Specifically, these yarns are characterized by a linear density that exceeds 52 tex but does not exceed 80 tex. This means the yarn is finer than those classified under 5205.23.00 (exceeding 43 nm but not exceeding 52 nm) but coarser than those covered by 5205.26.00 (measuring less than 125 decitex but not less than 106.38 decitex). The defining criterion here is the yarn's weight per unit length, expressed in tex or its equivalent metric number.

The distinction from sibling categories hinges on this precise measurement of yarn fineness. For instance, yarns finer than 52 tex but not exceeding 43 tex would fall under 5205.23.00, while yarns coarser than 80 tex would move to subsequent codes within 5205.2. This category specifically targets yarns within the 52.01 to 80.00 tex range.

Within HTS code 5205.24.00, further subclassification is provided to distinguish between different spinning methods. The subcategories, 5205.24.00.20 for ring-spun yarns and 5205.24.00.90 for other yarns, allow for a more granular classification based on the manufacturing process. This distinction is important for trade statistics and can impact duty rates or origin determinations.
