3921.12.19.10 - Products with textile components in which vegetable fibers predominate by weight over any other single textile fiber

This HTS category, 3921.12.19.10, specifically classifies cellular products in sheet, film, foil, or strip form, made from polymers of vinyl chloride, which are combined with textile materials. The defining characteristic is that vegetable fibers, such as cotton or linen, must predominate by weight over any other single textile fiber present in the composite material. These are typically multi-layered products where a cellular vinyl chloride plastic forms one layer or component, and a textile fabric predominantly of vegetable fibers forms another, bonded or otherwise combined to create a single product. Examples might include vinyl-coated fabrics with a foamed vinyl chloride backing where the fabric facing is primarily composed of cotton.

At this level, the distinction from sibling category 3921.12.19.50, also described as "Other," is crucial. While both fall under "Combined with textile materials" for cellular vinyl chloride products, this specific subcategory (3921.12.19.10) narrows the scope based on the *predominant fiber type* within the textile component. Category 3921.12.19.50 would cover similar composite cellular vinyl chloride products with textile components, but where the textile is *not* predominantly of vegetable fibers, or where the textile component's fiber composition does not meet the vegetable fiber predominance criterion. Therefore, the precise composition of the textile material is the key differentiator.

As this node represents a leaf category within the HTS, there are no further subcategories. Classification within 3921.12.19.10 is definitive once the product meets the criteria of being a cellular sheet, film, foil, or strip of vinyl chloride polymers combined with textile materials, and where vegetable fibers constitute more than 50% by weight of the total textile fiber content. Proper documentation confirming the fiber composition of the textile component is essential for accurate classification under this heading.
