5402.39.31.90 - Other (600) 🖩

This HTS classification, 5402.39.31.90, specifically addresses "Other" single yarns of textured synthetic filament, not put up for retail sale, that fall outside of more specific subheadings. The core of this category lies in its designation as a single yarn, meaning it is composed of one strand of textured synthetic filament. The "textured" aspect signifies that the filament has undergone a process to impart bulk, stretch, or crimp, altering its natural smooth and straight form to improve its handling and end-use characteristics. This classification is for yarns that do not meet the criteria for polyethylene textured single yarns.

The distinction from the sibling category 5402.39.31.10, which covers textured single yarns of polyethylene, is critical. While both fall under the broader umbrella of textured synthetic filament single yarns, this specific subheading is for all other synthetic materials *except* polyethylene. Therefore, the material composition is the primary differentiator at this level.

As this node represents a leaf node within the HTS, there are no further subcategories to introduce. Classification under 5402.39.31.90 is final for textured synthetic filament single yarns that are not of polyethylene and not intended for retail sale. Examples of synthetic materials that would fall here include textured yarns made from polyester, nylon, or acrylic filaments, provided they meet the prior criteria of being single, textured, and not for retail sale.
