6207.19.90.30 - Other (852)

This classification, HTS Code 6207.19.90.30, specifically covers men's or boys' underpants and briefs that are not made of cotton or man-made fibers, and are also not of a type specifically designated elsewhere within the 6207.19.90 subheadings. This residual category is for undergarments of this nature when they are composed of other textile materials not otherwise specified.

The distinction from its sibling category, 6207.19.90.10, is crucial. That sibling explicitly covers underpants and briefs of man-made fibers. Therefore, this particular category is intended for items made from textile materials such as wool, silk, linen, or blends thereof, provided they are not otherwise classified. The "Other (852)" designation in the description signifies that these are not cotton or man-made fiber goods, and are not covered by more specific sub-classifications within the broader "Of other textile materials" grouping.

As this is a leaf node, there are no further subcategories. The classification criteria for this code rely heavily on the material composition of the underpants and briefs. When determining classification, one must first confirm the item is men's or boys' underpants or briefs, then ascertain it is not cotton (which falls under a prior heading), and finally confirm it is not of man-made fibers. If the garment meets these conditions and is composed of a textile material not explicitly detailed in other subheadings of 6207.19.90, it would fall under this residual classification.
