6208.91 - Of cotton:

HTS Code 6208.91 classifies women's or girls' garments similar to those in 6208, specifically "other" articles of apparel and clothing accessories, not knitted or crocheted, when made of cotton. This category encompasses a range of garments not explicitly covered by more specific subheadings within 6208. It is crucial to identify the primary textile material for accurate classification.

This subheading, 6208.91, is distinguished from its sibling category 6208.92.00, which covers similar items made from man-made fibers, and 6208.99, which applies to those constructed from other textile materials. Therefore, the presence of cotton as the predominant fiber is the defining characteristic for goods classified under 6208.91.

The subcategories within 6208.91 further refine the classification. 6208.91.10 specifically addresses bathrobes, dressing gowns, and similar loungewear, distinguishing them from other general "other" articles. 6208.91.30 is a residual category for any other cotton garments of this type not falling into the bathrobe or dressing gown classification, ensuring comprehensive coverage within the "other" designation for cotton.
