Lightweight unbleached cotton woven fabrics blended with textile materials other than man-made fibers — such as wool, linen, silk, or specialty natural fibers — and weighing no more than 200 g/m² are captured in this residual heading. The 'mixed with textile materials, NES' qualifier is the key differentiator from the man-made fiber blend headings: the non-cotton component here is neither predominantly synthetic nor a single well-defined fiber class. Such blends appear in niche apparel, artisanal textile, and technical fabric markets. Accurate fiber identification is critical, as the classification depends on confirming that no single man-made fiber category dominates the non-cotton content.
