5007.90.30.40 - Other

This HTS category, 5007.90.30.40, specifically covers woven fabrics of silk or silk waste that are not jacquard woven and contain 85 percent or more by weight of silk or silk waste. This classification applies to fabrics that do not fit into more specific subcategories within the broader "other" fabrics of silk. Examples include plain weaves, twills, satins, and other non-jacquard constructions, provided they meet the high silk content requirement and are not specifically designed with intricate woven patterns characteristic of jacquard looms.

It is important to distinguish this category from its sibling, 5007.90.30.20. While both fall under the umbrella of "not jacquard woven" fabrics with high silk content, the sibling category is specifically defined by its width exceeding 127 cm. Therefore, this current category encompasses fabrics that meet the silk content and weave type criteria but are either 127 cm or less in width, or the width is not a primary defining characteristic for its classification.

As a leaf node, this category does not have further subdivisions. Classification into this specific code hinges on meeting the criteria of being woven silk or silk waste fabric, containing 85% or more silk by weight, and not being jacquard woven. The absence of subcategories signifies that any fabric meeting these core requirements, and not already classified under a more specific provision (e.g., by width, as seen in its sibling), will be directed to this residual "other" classification.
