5514.21.00 - Of polyester staple fibers, plain weave

This category, HTS 5514.21.00, specifically classifies woven fabrics composed predominantly of polyester staple fibers, where these fibers constitute less than 85% by weight and are mixed mainly or solely with cotton. The fabric's weight must exceed 170 grams per square meter, and it must be dyed. The defining characteristic of this subcategory is its plain weave construction.

It is crucial to distinguish this category from its siblings. HTS 5514.22.00 covers fabrics with a 3-thread or 4-thread twill weave, including cross twill, also of polyester staple fibers and meeting the same weight and composition criteria. HTS 5514.23.00 and 5514.29.00 represent broader classifications for "Other woven fabrics" of polyester staple fibers within the same parent group, whereas 5514.21.00 is specifically reserved for those with a plain weave.

Within HTS 5514.21.00, further distinctions are made based on specific fabric constructions that utilize a plain weave. The subcategories include poplin or broadcloth (HTS 5514.21.00.20), known for its fine, smooth texture and characteristic crispness due to a high thread count in a plain weave. Additionally, plain weave duck (HTS 5514.21.00.90) is classified here, which is typically a sturdier fabric with a more open weave structure than poplin, often used for more durable applications. These subcategories allow for more granular classification based on the precise fabric construction within the plain weave limitation.
