5408.32.90.10 - Mixed mainly or solely with synthetic filaments (618)

This HTS category, 5408.32.90.10, specifically classifies woven fabrics composed primarily or exclusively of artificial filament yarn. These fabrics are further distinguished by being dyed and falling under the broader "Other" classifications within woven artificial filament fabrics. The key characteristic here is the predominant use of artificial filament yarn, which encompasses regenerated cellulose fibers like rayon or viscose, as opposed to synthetic filaments like polyester or nylon.

Distinguishing this category from its sibling, which is also "Other," lies in the specific sub-classifications that precede it. While the sibling might represent fabrics with different finishing treatments or constructions not specifically enumerated, this category is the final repository for dyed woven fabrics of artificial filament yarn that do not fit into more specific subdivisions. The "Mixed mainly or solely with synthetic filaments" qualifier is crucial, indicating that while artificial filament yarn is the primary component, a minor admixture of synthetic filaments is permissible without changing the fundamental classification.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the classification hinges on the definitive material composition (artificial filament yarn as the principal component) and the finishing treatment (dyed). Examples would include dyed rayon satin or dyed viscose taffeta where the yarns themselves are artificial filaments.
