5211.20.21 - Plain weave

This HTS category, 5211.20.21, specifically classifies bleached woven fabrics of cotton, containing less than 85 percent by weight of cotton and mixed mainly or solely with man-made fibers, which weigh more than 200 g/m². The defining characteristic of this subcategory is its weave structure: "Plain weave." This refers to the most basic weave pattern where each warp yarn passes over one weft yarn and under the next, creating a simple interlacing.

Distinguishing this category from its siblings, 5211.20.22 and 5211.20.29, is crucial. While all fall under the umbrella of bleached woven cotton blends weighing over 200 g/m², 5211.20.22 is reserved for fabrics exhibiting a 3-thread or 4-thread twill weave, including cross twill, which creates diagonal lines. 5211.20.29 encompasses all other bleached woven cotton blends meeting the weight and fiber content criteria that are not plain weave or twill.

Within this "Plain weave" classification, further subdivisions exist to account for specific fabric types. For instance, 5211.20.21.20 denotes poplin or broadcloth, fabrics known for their fine, even texture due to a high warp yarn count. Additionally, the subcategory labeled sheeting includes plain weave duck, distinguished by its sturdy construction, often used for durable applications. These subdivisions allow for more precise classification based on the specific plain weave fabric construction and its intended use.
