5209.42.00.20 - Weighing not more than 360 g/m² (225)

This HTS classification, 5209.42.00.20, specifically covers blue denim woven fabrics that are primarily composed of cotton (at least 85% by weight) and have a weight exceeding 200 g/m², but not exceeding 360 g/m². The defining characteristic of this subcategory is the fabric's weight range, which is crucial for differentiating it from other denim classifications. This category applies to fabrics where the blue color is achieved through the use of yarns of different colors, typically the classic warp-faced twill weave where the warp yarns are dyed blue and the weft yarns are white or undyed.

It is important to distinguish this classification from its sibling, 5209.42.00.40, which covers blue denim of the same cotton content and yarn composition but weighing *more than* 360 g/m². Therefore, the primary criterion for selecting 5209.42.00.20 over its sibling is the precise weight per square meter of the fabric. Both fall under the broader category of "Denim" and "Blue denim," but the weight threshold of 360 g/m² acts as the decisive factor in their separate classification.

As this is a leaf node within the HTS, there are no further subcategories branching from 5209.42.00.20. Classification at this level is final based on the specified material content, weave type, color characteristic, and the weight range of not more than 360 g/m². Examples of goods falling under this classification would include denim fabric intended for the production of apparel such as jeans, jackets, and skirts, where the fabric meets all the aforementioned weight and composition criteria.
