5007.10.30 - Containing 85 percent or more by weight of silk or silk waste

This HTS classification, 5007.10.30, specifically covers woven fabrics where noil silk constitutes 85 percent or more of the total weight. Noil silk is a byproduct of silk spinning, characterized by its shorter fibers and somewhat coarser texture compared to spun silk. These fabrics are derived from this particular type of silk waste, distinguishing them from woven fabrics made from other silk forms or blended with significant amounts of other fibers.

Within the broader category of "Woven fabrics of silk or of silk waste," this HTS code is distinct from its sibling, 5007.10.60, which encompasses other woven fabrics of silk or silk waste not meeting the specific 85% noil silk content criteria. The primary differentiator lies in the precise composition, with 5007.10.30 being exclusively for fabrics heavily dominated by noil silk.

The subcategory, 5007.10.30.90, further refines this classification by distinguishing between fabrics that are jacquard woven and those that are not. This subdivision allows for more granular categorization based on the weaving technique employed, acknowledging the potential differences in complexity, design, and intended end-use between intricately patterned jacquard fabrics and simpler weaves made from noil silk.
