6303.99.00.30 - Containing 85 percent or more by weight of silk or silk waste

This HTS category, 6303.99.00.30, specifically classifies curtains, drapes, and interior blinds, as well as curtain or bed valances, that are made up of textile materials other than those specifically enumerated in the preceding subcategories. The defining characteristic for this particular classification is that the article must contain 85 percent or more by weight of silk or silk waste. This ensures that articles predominantly composed of silk, and not falling into more specific classifications based on other primary materials, are accurately categorized.

The distinction between this category and its sibling, 6303.99.00.60 (Other), lies in the precise material composition. While both fall under "Of other textile materials" and "Other," 6303.99.00.30 is reserved for articles where silk or silk waste is the overwhelming component by weight. The sibling category would encompass made-up textile articles for windows and beds that do not meet this specific silk content threshold or are made from other non-enumerated textile materials.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification into 6303.99.00.30 hinges entirely on meeting the criteria of being a curtain, drape, blind, or valance, and containing at least 85 percent by weight of silk or silk waste. For example, a silk drape with intricate embroidery that predominantly uses silk thread would fall here. If the embroidery used a significantly different material that altered the overall weight composition below the 85% silk threshold, it would likely be classified elsewhere.
