5407.91.20.50 - Satin weave or twill weave (628) 🖩

This HTS category, 5407.91.20.50, specifically classifies woven fabrics of synthetic filament yarn that are unbleached or bleached, and fall under the "other" category within woven fabrics of synthetic filament yarn. The defining characteristic of this subcategory is its weave structure, which is either a satin weave or a twill weave, as indicated by the parenthetical code (628). These fabrics are not defined by a specific end-use but rather by their construction and the type of yarn used, which must be synthetic filament.

It is important to distinguish this category from its siblings. While all are woven fabrics of synthetic filament yarn, unbleached or bleached, and categorized as "other," they are differentiated by their specific weave types. For example, 5407.91.20.20 covers poplin or broadcloth, 5407.91.20.30 covers sheeting, and 5407.91.20.40 covers printcloth. This category, 5407.91.20.50, is for those fabrics that exhibit either a satin weave, known for its sheen and smooth surface due to a specific interlacing pattern, or a twill weave, characterized by diagonal parallel ribs. Any other weave structures not specifically listed under the other sibling categories would also fall under the "other" sibling (5407.91.20.90).

As this classification is a leaf node, there are no further subcategories. Classification at this level hinges on the correct identification of the weave as either satin or twill, in conjunction with the preceding criteria of being a woven fabric of synthetic filament yarn, unbleached or bleached, and not fitting into the more specific weave descriptions of its siblings. Examples of fabrics that would fall here include certain satins used for linings or apparel, and various twills used for durable goods or certain types of clothing, provided they meet all other stipulated criteria for synthetic filament yarn.
