5516.91.00.60 - Satin weave or twill weave (617)

This HTS category, 5516.91.00.60, specifically classifies woven fabrics of artificial staple fibers that are manufactured using either a satin weave or a twill weave construction. These fabrics, while falling under the broader umbrella of "other" artificial staple fiber woven fabrics that are unbleached or bleached, are distinguished by these particular weave structures, which impart distinct surface characteristics and drape.

Unlike sibling categories such as poplin, sheeting, printcloth, cheesecloth, or duck, the defining feature here is the satin weave's characteristic smooth, lustrous surface created by long floats of warp or weft yarns, or the twill weave's diagonal parallel ribs, produced by the interlacing of warp and weft yarns. These weave patterns significantly influence the fabric's appearance, hand, and end-use applications. Since this is a leaf node, the classification is complete at this level, and the specific designation of "satin weave or twill weave" fully defines the scope of goods covered.
