High-tenacity viscose rayon yarn — engineered for superior tensile strength compared to standard viscose — produces woven fabrics used in industrial applications such as tire cord, conveyor belting, and technical reinforcement textiles, distinguishing this heading sharply from conventional apparel-grade rayon wovens. The 'high tenacity' specification is a performance criterion, not merely a marketing term, and importers should be prepared to provide yarn tenacity test data (typically expressed in cN/tex) to support classification. Pile, chenille, narrow, and special-purpose fabrics are explicitly excluded, keeping this heading focused on flat, broad woven constructions for industrial end uses.
