5211.43.00 - Other fabrics of 3-thread or 4-thread twill, including cross twill

This HTS category, 5211.43.00, specifically classifies other fabrics of cotton that are constructed using a 3-thread or 4-thread twill weave, including cross twill. These fabrics are characterized by their cotton content, falling under the broader scope of woven cotton fabrics weighing more than 200 g/m². The defining feature is the twill weave pattern, which creates a distinct diagonal line effect on the fabric's surface.

Distinguishing this category from its siblings, 5211.41.00 (plain weave) and 5211.42.00 (denim), is crucial. While all are woven cotton fabrics under 5211, this category excludes plain weave structures and the specific denim construction. The "other fabrics" designation within the sibling group (5211.49.00) is essentially a residual category, and 5211.43.00 provides more granular detail by specifying the twill weave construction.

Further classification within 5211.43.00 is based on the finishing treatment applied to the fabric. The subcategories, 5211.43.00.30 and 5211.43.00.50, differentiate between fabrics that are not napped and those that have been napped, respectively. Napping is a mechanical process that raises the fiber ends on the surface of the fabric, creating a softer, fuzzier texture, which is the primary criterion for distinguishing these two subdivisions.
