5513.29.00.50 - Satin weave or twill weave (617)

This HTS classification, 5513.29.00.50, specifically designates dyed woven fabrics of synthetic staple fibers that contain less than 85% synthetic staple fibers by weight, are mixed predominantly or solely with cotton, and do not exceed 170 grams per square meter in weight. The defining characteristic of this category is the weave structure: satin weave or twill weave. These weaves create distinct fabric surfaces and drape qualities, differentiating them from other weaves like poplin, sheeting, or printcloth, which are classified under separate sibling codes.

Unlike poplin or sheeting fabrics which typically feature a plain weave, or printcloth characterized by a simpler construction, satin weave results in a smooth, lustrous surface due to a specific interlacing pattern where warp threads float over multiple weft threads. Twill weave, on the other hand, is characterized by its diagonal lines or ridges, a result of shifting the warp and weft intersections. This particular classification excludes fabrics with other weaves, such as the oxford cloth found under 5513.29.00.60, which has a basket weave structure.

As this is a leaf node, there are no further subcategories. Classification within 5513.29.00.50 hinges directly on the presence of a satin or twill weave in dyed fabrics meeting the specified fiber content, weight, and mix criteria. Therefore, careful examination of the fabric's construction and weave pattern is paramount for accurate classification.
