5513.31.00.00 - Of polyester staple fibers, plain weave (218)

This HTS classification, 5513.31.00.00, specifically covers woven fabrics of polyester staple fibers that are characterized by a plain weave construction. These fabrics weigh no more than 170 grams per square meter and are part of a broader category of woven fabrics made from synthetic staple fibers, which contain less than 85% by weight of these fibers, and are mixed predominantly or solely with cotton. The "plain weave" designation is a critical identifying characteristic, referring to the simplest and most common of textile weaves where threads interlace at right angles in a one-over-one pattern.

To distinguish this category from its sibling, 5513.39.01 ("Other woven fabrics"), it is essential to note that this code is reserved for plain weave fabrics only. The "Other" category would encompass woven fabrics within the scope of 5513.30 that are *not* plain weave, such as twill weave or satin weave fabrics, provided they meet all other criteria regarding fiber content and weight.

As this classification is a leaf node, there are no further subcategories. Therefore, the focus for classification under 5513.31.00.00 remains on accurately identifying the material as polyester staple fibers, the weave as plain, the presence of cotton as a significant component (but less than 15% by weight), and confirming the fabric's weight does not exceed 170 g/m². Typical examples would include certain types of poplin, broadcloth, or percale fabrics made with the specified fiber composition and weave.
