6108.29 - Of other textile materials:

This HTS category, 6108.29, encompasses women's or girls' briefs and panties, knitted or crocheted, that are made from textile materials other than cotton or man-made fibers. It specifically covers undergarments designed for personal wear, adhering to the general scope of Chapter 61, which pertains to knitted or crocheted apparel.

The crucial distinction of this subcategory lies in its material composition. Unlike its sibling categories, 6108.21 which exclusively covers briefs and panties of cotton, and 6108.22 which pertains to those made from man-made fibers, 6108.29 is for garments composed of other textile materials. This includes, but is not limited to, items made predominantly from natural fibers such as silk, wool, or linen, or blends thereof, provided they do not meet the criteria for the "cotton" or "man-made fibers" categories.

Within this category, further refinement is provided by its subcategories. 6108.29.10.00 specifically addresses briefs and panties containing 70 percent or more by weight of silk or silk waste, highlighting the premium nature of these items. The residual subcategory, 6108.29.90.00, covers all other briefs and panties falling under 6108.29 that do not meet the silk-specific criterion, ensuring comprehensive classification for all remaining "other textile material" compositions.
