5211.31.00 - Plain weave

This HTS category encompasses woven fabrics of cotton, specifically those containing less than 85% cotton by weight, primarily mixed with man-made fibers, and exceeding 200 grams per square meter in weight. The defining characteristic of this grouping is that the fabric has been dyed a uniform color. This differentiates it from unbleached or bleached fabrics within the same broader family of cotton-containing woven goods.

Within the dyed category, this specific classification, 5211.31, is dedicated to fabrics woven in a plain weave construction. This contrasts with sibling categories such as 5211.32.00, which cover 3-thread or 4-thread twill weaves, including cross twill, and 5211.39.00, which encompasses all other types of woven structures not otherwise specified. The plain weave, characterized by a simple interlacing of warp and weft threads, forms the primary distinction at this level.

The subcategories further refine the classification of these plain weave dyed fabrics based on specific weave types. The primary subdivision is for poplin or broadcloth (5211.31.00.20), known for its fine, crisp texture. Additionally, sheeting fabrics are covered, with a specific designation for plain weave duck (5211.31.00.90), a heavier, more durable plain weave fabric often used for workwear or furnishings. These subdivisions allow for a more precise identification of the fabric's construction and intended use.
