3918.90.30.00 - Other

This HTS category, HTS 3918.90.30.00, encompasses wall or ceiling coverings made of plastics, specifically those with a backing composed of textile fibers other than man-made fibers. These coverings are intended for installation on interior walls and ceilings and are typically presented in rolls or as tiles. The "other" designation in this context signifies that the textile backing is not derived from synthetic or artificial fibers but rather from natural fibers such as cotton, wool, linen, or silk.

This classification is distinguished from its sibling category, 3918.90.20.00, "With a backing of man-made fibers," by the specific material of the backing. While both categories fall under "Of other plastics" and are for wall or ceiling coverings, the crucial differentiating factor lies in the fiber composition of the underlying support material. This distinction is essential for accurate tariff application based on the material science of the product.

As this is a leaf node, there are no further subcategories to introduce. Classification under this code hinges on the confirmation that the plastic wall or ceiling covering has a textile backing which is demonstrably not composed of man-made fibers. Examples of such backing materials would include cotton or jute.
