6104.53 - Of synthetic fibers:

This HTS category, 6104.53, specifically classifies women's or girls' skirts and divided skirts that are knitted or crocheted and made from synthetic fibers. This heading is a subdivision of "Skirts and divided skirts" within the broader chapter for knitted or crocheted articles of apparel. The defining characteristic for inclusion here is the primary textile material; these garments must be predominantly composed of synthetic fibers.

This category is distinguished from its siblings by its material composition. For instance, 6104.51 covers skirts of wool or fine animal hair, while 6104.52 pertains to those made of cotton. Therefore, 6104.53 serves as the designated classification for skirts and divided skirts where synthetic fibers form the primary component, differentiating them from garments constructed from natural fibers like wool or cotton.

Within this category, further subdivisions exist to refine classification based on specific material blends. Subcategory 6104.53.10.00 pertains to skirts and divided skirts containing 23 percent or more by weight of wool or fine animal hair, indicating a blend where synthetic fibers are present but complemented by a significant portion of natural fibers. The subcategory 6104.53.20, "Other," encompasses all remaining skirts and divided skirts of synthetic fibers that do not meet the specific blend criteria of 6104.53.10.00.
