3918.10.40.10 - Woven

This HTS category, 3918.10.40.10, specifically covers woven wall or ceiling coverings made from polymers of vinyl chloride. These are distinct from non-woven materials and are intended for installation on walls or ceilings, often serving decorative or protective purposes. The "woven" characteristic refers to the interlaced structure of textile fibers forming the material, differentiating it from other types of construction or fabric.

Within the broader category of "Wall or ceiling coverings: With a backing of textile fibers," this subheading distinguishes itself through its specific manufacturing technique. While its sibling category, 3918.10.40.50 "Other," would encompass non-woven textile-backed vinyl wall or ceiling coverings, this subheading is exclusively for those constructed using a woven textile backing. This distinction is critical for accurate tariff assessment, as the method of textile construction can influence import duties.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges entirely on the material being a polymer of vinyl chloride, being a wall or ceiling covering with a textile backing, and specifically that textile backing being woven. Practical classification will involve verifying the woven structure of the textile component and confirming the primary material as vinyl chloride polymer.
