5515.29.00 - Other

This HTS category, 5515.29.00, encompasses "Other" woven fabrics of acrylic or modacrylic staple fibers that are not mixed mainly or solely with man-made filaments (5515.21.00) or wool/fine animal hair (5515.22). The defining characteristic here is that these fabrics are composed primarily of acrylic or modacrylic staple fibers, woven into a fabric. The "Other" designation signifies that these are fabrics which do not fall under more specific material mixtures or weave types already provided for within the broader group of acrylic or modacrylic woven fabrics.

The crucial distinction lies in the composition of the warp and weft yarns. Unlike its sibling categories, this sub-heading is for woven fabrics where the primary fiber content is acrylic or modacrylic staple fibers, and any other fiber content is not dominant. For instance, if a fabric is predominantly acrylic staple fiber but contains a significant proportion of cotton or other vegetable fibers, it would likely fall under a different HTS heading. This category focuses on fabrics where the acrylic or modacrylic staple fiber is the defining element, woven into a textile.

Within this "Other" classification, further subdivisions exist to refine the classification based on specific visual characteristics and weave structures. These include fabrics made from yarns of different colors, excluding specific types like blue denim or jacquard weaves, and blue denim itself, which is often characterized by its twill weave and indigo dyeing. The existence of these subcategories highlights the importance of detailed visual and structural inspection for accurate classification, ensuring that fabrics are precisely categorized based on their manufacturing and aesthetic properties beyond just their fiber content.
