5512.19.00.45 - Satin weave or twill weave (617)

This HTS classification, 5512.19.00.45, specifically covers woven fabrics of synthetic staple fibers, where synthetic staple fibers constitute 85 percent or more by weight. Further refining this, the fabric must contain 85 percent or more by weight of polyester staple fibers and fall under the "Other" category within the "Other" sub-classification. The defining characteristic for this particular code is the weave construction: satin weave or twill weave. These weaves are distinguished by their interlacing patterns, which create distinct surface characteristics and drape.

To differentiate this code from its siblings, one must consider the specific weave types listed. For instance, categories like 5512.19.00.15 (Poplin or broadcloth), 5512.19.00.30 (Printcloth), 5512.19.00.40 (Duck), and others represent distinct fabric structures. Satin weaves are characterized by a smooth, lustrous surface achieved by floating warp or weft yarns over multiple others, while twill weaves feature diagonal parallel ribs. Therefore, the presence of either a satin or twill weave is the critical determinant for classifying goods under this specific HTS code, distinguishing them from fabrics woven in other patterns.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level relies directly on meeting the stipulated criteria for material content (85% or more polyester staple fibers) and the specific weave type (satin weave or twill weave). Importers and exporters should ensure meticulous examination of the fabric's construction and fiber composition to accurately apply this classification.
