5205.11.10.00 - Unbleached, not mercerized (300)

This HTS classification, 5205.11.10.00, specifically identifies single yarns of cotton, derived from uncombed fibers, that do not exceed 14 tex (which corresponds to a yarn count of 14 nm or higher). These yarns must contain at least 85 percent by weight of cotton and are not packaged for retail sale. The "unbleached, not mercerized" designation is a critical qualifier, meaning the cotton has not undergone bleaching processes or mercerization, which alters the yarn's sheen and strength.

This category is distinguished from its sibling, 5205.11.20.00 ("Other"), by the specific processing state of the cotton. While both fall under single yarn of uncombed fibers not exceeding 14 tex, the "Other" category would encompass yarns that have undergone bleaching, mercerization, or other treatments not covered by the precise specifications of 5205.11.10.00. Therefore, the presence or absence of bleaching and mercerization is the key differentiator at this level.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification into 5205.11.10.00 is definitive based on the yarn's material composition (at least 85% cotton), construction (single yarn, uncombed fibers), yarn size (not exceeding 14 tex), presentation (not for retail sale), and processing (unbleached and not mercerized). Importers and exporters must carefully verify these characteristics to ensure accurate classification.
