5515.12.00 - Mixed mainly or solely with man-made filaments

This HTS category, 5515.12.00, specifically classifies woven fabrics composed primarily or exclusively of synthetic staple fibers. The defining characteristic is the presence of man-made filaments as the predominant or sole fiber component. These fabrics are distinct from those where natural fibers or specific blends form the majority.

To further differentiate, this category sits under "Other woven fabrics of synthetic staple fibers" and specifically "Of polyester staple fibers." It is distinguished from its siblings by the type of fiber mixed with the polyester staple fibers. For instance, 5515.11.00 covers fabrics mixed with viscose rayon staple fibers, while 5515.13 pertains to mixes with wool or fine animal hair. This category, 5515.12.00, therefore encompasses woven polyester staple fiber fabrics that are *not* primarily mixed with viscose rayon or wool/fine animal hair.

The subcategories within 5515.12.00 provide for more granular classification based on fabric construction and weave. These include specific types like poplin or broadcloth (5515.12.00.10), printcloth (5515.12.00.30), and fabrics with a satin or twill weave (5515.12.00.40). The catch-all category, "Other" (5515.12.00.90), is used for any woven polyester staple fiber fabrics not fitting the more specific descriptions, ensuring comprehensive coverage within this section.
