5515.21.00.10 - Poplin or broadcloth (625)

This classification, HTS Code 5515.21.00.10, specifically covers woven fabrics composed of synthetic staple fibers, where these synthetic staple fibers are predominantly acrylic or modacrylic. Crucially, these fabrics are characterized by being mixed mainly or solely with man-made filaments. The "poplin or broadcloth" designation within the description refers to specific weave structures and fabric constructions that are common for this type of material. These fabrics typically exhibit a fine, even surface with a relatively high thread count, often resulting in a smooth feel and a slight sheen.

Distinguishing this category from its siblings, 5515.21.00.10 differentiates itself from "Sheeting" (5515.21.00.20) and "Printcloth" (5515.21.00.30) by its specific weave and construction. While sheeting and printcloth also fall under woven fabrics of acrylic or modacrylic staple fibers mixed with man-made filaments, the "poplin or broadcloth" designation points to a denser weave with a higher number of warp yarns (running lengthwise) than weft yarns (running widthwise), creating a characteristic smooth, lustrous surface that is distinct from the broader definitions of sheeting or printcloth. Similarly, it differs from "Satin weave or twill weave" (5515.21.00.40) by the specific weave structure identified.

As this is a leaf node within the HTS, there are no further subcategories that subdivide this classification. Therefore, the focus for classification within 5515.21.00.10 remains on confirming that the fabric is indeed constructed from acrylic or modacrylic staple fibers, is mixed with man-made filaments, and possesses the specific characteristics of a poplin or broadcloth weave. Examples of such fabrics would include those used in lightweight apparel, linings, and certain home furnishings where a smooth finish and drape are desired.
