6115.10.15.20 - Of wool or fine animal hair (459)

This HTS classification pertains to graduated compression panty hose and tights that are knitted or crocheted, and are constructed from textile materials *other than* cotton. These garments are specifically designed to apply graduated pressure to the legs, promoting circulation and often used for medical purposes such as managing varicose veins or post-surgery recovery. The defining characteristic is the graduated compression feature, distinguishing them from standard panty hose and tights.

Within the broader category of graduated compression hosiery, this subcategory is differentiated from its siblings by its material composition. It is separate from "Of cotton" (6115.10.15.10) due to the absence of cotton as the primary textile material. Furthermore, it is distinct from "Other" (6115.10.15.40) which would encompass graduated compression panty hose and tights made from materials not specifically enumerated at this level.

As a leaf node, this classification does not have further subcategories. Therefore, classification under 6115.10.15.20 relies on the accurate identification of the garment as graduated compression panty hose or tights, its knitted or crocheted construction, and the confirmation that its textile composition is neither cotton nor falls under any other specific material designation at this level of detail, but rather comprises a distinct "other textile material."
