6115.99.40.00 - Containing 70 percent or more by weight of silk or silk waste

This HTS classification covers hosiery, knitted or crocheted, that is not panty hose, tights, stockings, socks, or graduated compression hosiery, and also excludes footwear without applied soles. Specifically, this category applies to items meeting these criteria where the textile material comprises 70 percent or more by weight of silk or silk waste. This designation focuses on the primary fiber content to differentiate from other material compositions within the broader hosiery category.

Distinguishing this category from its siblings is crucial for accurate classification. The sibling category "Of artificial fibers" would apply to hosiery meeting the same general description but primarily composed of artificial fibers such as rayon, nylon, or polyester. The other sibling category, "Other," is a residual category for hosiery not otherwise specified by material composition. Therefore, the 70% silk or silk waste requirement is the definitive factor for inclusion here.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 6115.99.40.00 is final once the conditions of material content (70% or more silk or silk waste) and the exclusion of specific hosiery types (panty hose, tights, stockings, socks, graduated compression hosiery, and footwear without applied soles) are met. Importers should ensure accurate documentation of the fiber content to support this classification.
