5407.83.00.40 - Satin weave or twill weave (628)

This HTS classification, 5407.83.00.40, specifically covers woven fabrics of synthetic filament yarn that are characterized by a satin weave or a twill weave. These fabrics contain less than 85 percent by weight of synthetic filaments, with the remaining significant portion being cotton, and are composed of yarns of different colors. The defining aspect here is the specific weave structure; satin weave typically presents a smooth, lustrous surface with warp threads floating over multiple weft threads, while twill weave creates a diagonal ribbed pattern.

To distinguish this category from its siblings, it is crucial to recognize the specific weave patterns. For instance, 5407.83.00.10 (Poplin or broadcloth) and 5407.83.00.20 (Sheeting) represent different weave structures that do not fall under the satin or twill designation. Similarly, 5407.83.00.30 (Printcloth) and 5407.83.00.90 (Other) are distinct categories at the same level, with "Printcloth" often referring to a specific type of closely woven fabric and "Other" encompassing remaining fabrics within the broader group of colored-yarn woven fabrics containing less than 85% synthetic filaments.

As a leaf node in the HTS system, 5407.83.00.40 does not have further subcategories. Therefore, classification within this heading relies on accurately identifying the fabric's composition (less than 85% synthetic filaments, mixed mainly or solely with cotton, and of yarns of different colors) and confirming the presence of a satin or twill weave as the primary differentiating factor from other woven fabrics in heading 5407.
