5205.15.10.00 - Unbleached, not mercerized (300) 🖩

This HTS classification covers single cotton yarns that are unbleached and not mercerized. Crucially, these yarns must contain 85 percent or more by weight of cotton and are not packaged for retail sale. The yarns are derived from uncombed fibers and possess a specific fineness, exceeding 80 tex (nm - number of meters per gram). This category is distinct from other single yarns of uncombed fibers that are not in this fineness range or have different processing treatments.

The primary distinguishing factor for this specific code, 5205.15.10.00, is the "Unbleached, not mercerized (300)" modifier, which indicates the yarn's condition and processing. It differentiates these yarns from any "Other" single yarns of uncombed fibers exceeding 80 nm that may have undergone different finishing processes or possess other characteristics. The "(300)" likely refers to an internal or specific trade identifier relevant to the customs authority.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific classification. Therefore, the focus for accurate classification lies in confirming that the yarn meets all preceding criteria: being a single yarn of uncombed cotton fibers, weighing 85% or more cotton, not put up for retail sale, not mercerized, unbleached, and exceeding 80 tex in fineness.
