3921.12.50.00 - Other

This HTS category, 3921.12.50.00, specifically covers other plates, sheets, film, foil, and strip of plastics that are cellular and made from polymers of vinyl chloride. This designation applies to such products that are not further classified under any other specific subheading within the cellular vinyl chloride category. The "Other" designation suggests a residual classification for items that meet the primary criteria of being cellular, vinyl chloride-based plastic sheeting, but do not fit into more precisely defined sub-classifications.

While the sibling category "Combined with textile materials" at the same level distinguishes itself by the inclusion of textile components, this category solely focuses on cellular vinyl chloride plastic materials in sheet form. Therefore, the presence of any significant textile reinforcement or combination would lead to classification under the sibling entry. This category, by contrast, would encompass cellular vinyl chloride sheeting that is purely plastic, without integrated textile elements.

As this is a leaf node, there are no further subcategories. Classification under 3921.12.50.00 is determined by the material composition (polymers of vinyl chloride), physical form (cellular plates, sheets, film, foil, or strip), and the absence of specific features that would place it in a more detailed subheading, such as integration with textile materials. Practical classification would rely on identifying the cellular structure of the vinyl chloride polymer product in its described sheet forms.
