5205.14.10.00 - Unbleached, not mercerized (300)

This HTS classification, 5205.14.10.00, specifically identifies single yarn made from uncombed cotton fibers. The defining characteristic of this category is that the yarn must weigh 85% or more cotton by weight and exceed 52 but not 80 tex (equivalent to nm count). Crucially, these yarns are not mercerized and are in an unbleached state. They are also not packaged for retail sale, indicating their intended use for further manufacturing processes within the textile industry.

This category is distinct from its sibling, 5205.14.20.00, which is designated for "Other" single yarns of uncombed fibers falling within the same tex range (exceeding 52 but not exceeding 80). While both categories pertain to uncombed cotton yarn within the specified tex range, 5205.14.10.00 is exclusively for unbleached and unmercerized varieties. The "Other" designation at the sibling level likely encompasses variations in finishing treatments or potential exceptions not explicitly defined within the primary heading.

As a leaf node in the HTS classification structure, 5205.14.10.00 represents a specific endpoint for classification. There are no further subdivisions under this code. Therefore, any single yarn composed of at least 85% cotton, spun from uncombed fibers, with a tex count between 52 and 80, and that is unbleached and unmercerized, will be classified here, provided it is not put up for retail sale. This precise definition ensures accurate customs reporting and tariff application for these intermediate textile goods.
