Coarse animal hair — encompassing fiber from horses, cattle, camels (excluding the fine undercoat), and similar animals — serves industrial and specialty end uses such as upholstery stuffing, brush manufacturing, felt production, and acoustic insulation rather than apparel textiles. The coarse designation reflects fiber diameter above the thresholds that define fine hair, and the distinction is critical at the classification boundary. Unlike fine hair, coarse animal hair generally faces less complex species-based duty differentiation, though origin documentation remains important.
