5513.13.00.20 - Satin weave or twill weave (617)

This HTS category, 5513.13.00.20, specifically classifies woven fabrics of polyester staple fibers that are unbleached or bleached. These fabrics are characterized by containing less than 85 percent by weight of synthetic staple fibers, with cotton being the primary other component. Crucially, the weight of these fabrics does not exceed 170 grams per square meter. The defining characteristic of this particular subcategory lies in its weave structure, which is explicitly limited to satin or twill weaves.

Distinguishing this classification from its siblings, 5513.13.00.40 (Oxford cloth) and 5513.13.00.90 (Other), is the specific weave pattern. While Oxford cloth is a distinct basket weave variation, and the "Other" category encompasses all other woven fabrics not otherwise specified, 5513.13.00.20 is narrowly focused on fabrics exhibiting either a satin weave (known for its lustrous surface and smooth feel) or a twill weave (identified by diagonal ribbing). This distinction is critical for accurate customs declaration and duty assessment.

As 5513.13.00.20 represents a leaf node in the HTS database, there are no further subcategories. Therefore, classification within this node relies on confirming the fabric's composition (polyester staple fibers mixed mainly with cotton, <85% synthetic), weight (not exceeding 170 g/m²), bleaching status (unbleached or bleached), and the presence of either a satin or twill weave. Examples of products that would fall under this classification include certain types of linings, apparel fabrics, and home furnishings that meet these precise criteria.
