6108.22 - Of man-made fibers:

This HTS category, 6108.22, specifically covers women's or girls' briefs and panties knitted or crocheted, when they are made from man-made fibers. These articles are intended to be worn as undergarments and fall under the broader classification of women's or girls' slips, petticoats, briefs, panties, night dresses, pajamas, negligees, bathrobes, dressing gowns, and similar articles, knitted or crocheted. The key defining characteristic for inclusion here is the material composition; the garments must be constructed predominantly from synthetic or artificial fibers.

Category 6108.22 is distinguished from its sibling categories by its material. Specifically, it differs from 6108.21, which covers similar briefs and panties made of cotton. While both are knitted or crocheted undergarments for women and girls, the fiber content dictates the classification. This category also stands apart from 6108.29, which is a broader category for briefs and panties made of "other textile materials" not specified elsewhere, implying that 6108.22 is for a specific, defined set of man-made fibers.

Within this category for man-made fiber briefs and panties, two subcategories exist to further refine the classification. The first, 6108.22.10.00, is for disposable briefs and panties specifically designed for one-time use. This distinction recognizes articles intended for immediate disposal after a single wear, often for hygienic or medical purposes. The second subcategory, 6108.22.90, encompasses all other briefs and panties made of man-made fibers that do not meet the criteria for disposable articles, covering the vast majority of standard reusable undergarments in this material group.
