5903.20.30.10 - Of wool or fine animal hair (414)

This HTS category, 5903.20.30.10, specifically classifies textile fabrics that have been impregnated, coated, covered, or laminated with polyurethane, and are further specified as being made of wool or fine animal hair. These are not basic fabrics but rather composite materials where the textile substrate's characteristics are significantly altered by the polyurethane application, rendering them suitable for specialized industrial uses as defined within Chapter 59. The presence of wool or fine animal hair as the base textile is the defining material criterion for this subclassification.

This classification distinguishes itself from its sibling category, 5903.20.30.90 ("Other"), by the explicit requirement of the textile component being wool or fine animal hair. The sibling category would encompass polyurethane-coated fabrics made from other textile fibers, such as cotton, synthetic, or man-made fibers. Therefore, the accurate classification hinges on a precise identification of the primary textile material comprising the fabric prior to its impregnation or coating with polyurethane.

As this is a leaf node, there are no further subcategories. The classification is complete at this level based on the polyurethane coating and the specific wool or fine animal hair content of the underlying textile fabric. Classification professionals should focus on verifying both the presence of polyurethane coating and the specific nature of the textile material to correctly assign goods to this HTS code.
