Overview

This HTS classification, 5402.31.30.00, covers single yarns of nylon or other polyamides that have been textured. The key defining characteristics are that the yarn is not put up for retail sale, it is a filament yarn (excluding sewing thread and monofilaments under 67 decitex), and its decitex measurement for a single yarn does not exceed 500. "Textured" refers to yarns that have undergone a process to impart bulk, stretch, or other aesthetic or functional properties, distinguishing them from smooth filament yarns.

At this level, the primary distinction is between single yarns and multiple (folded) or cabled yarns. While both fall under the broader category of textured nylon or polyamide yarns not exceeding 500 decitex, 5402.31.30.00 specifically pertains to yarns composed of a single strand. In contrast, its sibling category, 5402.31.60.00, would encompass yarns formed by twisting two or more single strands together.

As this node is a leaf node within the HTS, there are no further subdivisions. Therefore, classification under 5402.31.30.00 is definitive for single, textured nylon or polyamide filament yarns meeting the specified decitex criteria and not intended for direct retail sale. Examples would include bulked nylon yarns used in the manufacturing of hosiery, apparel, or upholstery fabrics.
