5403.49 - Other:

This HTS category, 5403.49, encompasses "Other" artificial filament yarns, not put up for retail sale, excluding artificial monofilaments of less than 67 decitex. These are multi-filament yarns that are either folded (plied) or cabled. The defining characteristic is their composition and construction, fitting within the broader scope of man-made filament yarns not intended for direct consumer use.

Unlike sibling categories 5403.41 (of viscose rayon) and 5403.42 (of cellulose acetate), this category is not defined by the specific cellulosic derivative material. Instead, it serves as a catch-all for multi-filament, multiple or cabled artificial filament yarns made from artificial filaments where the material is neither viscose rayon nor cellulose acetate, or where the specific material composition is not otherwise specified under a more particular heading.

Within this category, further distinctions are made to refine classification. Subcategory 5403.49.10.00 specifically covers "Textured yarn," which has undergone processes to impart bulk, crimp, or loops, altering its natural smooth filament form. The remaining yarns, not meeting the definition of textured yarn, are classified under 5403.49.90.00 as "Other." This subdivision allows for precise identification of yarns based on whether they have been artificially textured or remain in their original smooth filament state.
