5403.49.90.00 - Other (606)

This HTS code, 5403.49.90.00, encompasses "Other" artificial filament yarn, not put up for retail sale, that is multiple (folded) or cabled and not textured. It falls under the broader category of artificial filament yarn, excluding sewing thread and artificial monofilament of less than 67 decitex. The key defining characteristic of this classification is its construction as folded or cabled yarn, composed of artificial filaments, and crucially, its lack of the texturing treatment found in its sibling category.

This category is distinguished from its sibling, 5403.49.10.00 (Textured yarn), by the absence of texturing. While both are multiple or cabled artificial filament yarns not put up for retail sale, 5403.49.10.00 specifically includes yarns that have undergone processes like air-jet texturing or heat-setting to introduce bulk, stretch, or other desirable aesthetic or functional properties. Therefore, yarns in this 5403.49.90.00 classification are typically smooth, untwisted, or twisted in a way that does not impart significant bulk or loft, making them distinct from their textured counterparts.

As a leaf node in the HTS structure, there are no further subcategories under 5403.49.90.00. Classification within this code is determined by identifying artificial filament yarn that is presented in a multiple (folded) or cabled form, is not intended for retail sale, and does not possess any texturing treatments. Examples would include multiple strands of rayon or acetate filament yarn twisted together without any crimping or bulking process, used for industrial or manufacturing purposes.
