9404.40.90.23 - Containing 85 percent or more by weight of silk or silk waste

This HTS category, 9404.40.90.23, specifically covers quilts, bedspreads, eiderdowns, and duvets that have an outer shell composed of textile materials, and importantly, contain 85 percent or more by weight of silk or silk waste. This stringent material requirement is the defining characteristic, ensuring that products with a predominant silk composition are accurately classified.

While other categories at this level might cover similar bedding articles with outer shells of different textile materials, the key differentiator here is the explicit focus on silk content. For instance, sibling categories might exist for items with outer shells of synthetic fibers, cotton, or blends where silk is not the dominant material. Therefore, it is crucial for customs professionals to verify the precise material composition by weight to ensure correct classification.

As this is a leaf node in the HTS, there are no further subdivisions. Classification within this category hinges solely on the identified criteria: being a quilt, bedspread, eiderdown, or duvet, possessing an outer shell of textile material, and meeting the 85% silk or silk waste threshold by weight. This ensures a singular, precise classification for such high-silk content bedding articles.
