3921.13.19 - Other

This HTS category, 3921.13.19, encompasses cellular plates, sheets, film, foil, and strip made of polyurethanes that are combined with textile materials. The "Other" designation signifies that these goods do not fall under more specific subheadings within this broader category. The key defining characteristic is the composite nature, where a cellular polyurethane material is integrated with textile components.

Within the context of combined textile materials, this category is distinguished from its sibling, "Products with textile components in which man-made fibers predominate by weight over any other single textile fiber." While both involve polyurethane combined with textiles, the distinction lies in the predominant fiber type within the textile component. This specific subheading (3921.13.19) applies when the textile material is not predominantly man-made fibers.

The subcategories for this code, 3921.13.19.10 and 3921.13.19.50, further refine the classification based on the predominant type of textile fiber. Subheading 3921.13.19.10 specifically addresses products where vegetable fibers (such as cotton or linen) are the dominant fiber by weight. The remaining products, which do not meet the criteria for being predominantly vegetable fiber or predominantly man-made fiber, are classified under the residual subheading 3921.13.19.50, "Other."
