5403.39 - Other:

HTS code 5403.39 encompasses "Other" artificial filament yarn, not put up for retail sale and not classified under specific types like viscose rayon or cellulose acetate. This category serves as a residual classification for single yarns made from man-made filaments where the material composition or twist does not align with the preceding subheadings within 5403.3. It is important to note that this classification applies only to yarn not intended for immediate consumer use, excluding sewing thread and yarn packaged for retail sale.

This category is distinguished from its siblings, 5403.31 and 5403.32, which specifically cover viscose rayon yarns based on their twist (not exceeding or exceeding 120 turns per meter, respectively). Similarly, 5403.33 is for cellulose acetate yarns. Therefore, 5403.39 is for any other single artificial filament yarn that does not fall into these defined material or twist categories, as long as it meets the general criteria of artificial filament yarn not put up for retail sale.

Within HTS code 5403.39, further subdivisions exist to refine the classification. The subcategory 5403.39.10.00 specifically addresses "Textured yarn," which has undergone processes to alter its structure, giving it bulk or a crimped appearance. The remaining yarns that do not qualify as textured fall under the residual subheading 5403.39.90, "Other." This hierarchical structure allows for precise classification based on the specific characteristics and processing of the artificial filament yarn.
