Yarn-colored woven fabrics in this heading are explicitly distinguished from denim by the parenthetical 'except denim' qualifier, capturing heavier-weight checks, plaids, and stripes where the color pattern derives from pre-dyed yarns rather than surface printing or piece dyeing. At over 200 g/m² with a sub-85% cotton and manmade-fiber-dominant blend, these fabrics serve suiting, upholstery, and heavy shirting markets where pattern durability and fabric body are priorities. The dual classification criteria — yarn-color construction and non-denim identity — mean importers must be prepared to document both the weaving process and the absence of the characteristic denim twill structure.
