Lightweight bleached woven fabrics in this heading are distinguished by their mixed-fiber composition: cotton is the primary component, but the secondary fibers are neither predominantly manmade nor wool — falling instead into the residual 'textile materials, n.e.s.' category that captures blends with linen, ramie, silk, or other natural or specialty fibers. The bleached finish and sub-200 g/m² weight profile make these fabrics relevant for fine shirting, medical textile base cloths, and specialty apparel where a white or near-white ground is required. Correct classification depends on identifying all fiber components by weight, since the 'n.e.s.' fiber designation applies only when no single non-cotton fiber type qualifies as the predominant blend partner.
