3921.90.29.00 - Other

This HTS category, 3921.90.29.00, specifically covers "Other" plates, sheets, film, foil, and strip made of plastics. These are composite materials that are combined with textile materials, and critically, weigh more than 1.492 kilograms per square meter. This designation is for plastic sheeting products that do not fall under the more specific subcategories of textile-reinforced plastics, based on the predominant fiber type.

The distinction from its sibling categories is based on the composition of the textile component. HTS 3921.90.21.00 is for products where cotton predominates by weight, while 3921.90.25.00 is for products where man-made fibers predominate. This category, 3921.90.29.00, acts as a residual classification for plastic-textile composites exceeding the specified weight threshold when neither cotton nor man-made fibers are the dominant textile component by weight.

As this is a leaf node, there are no further subdivisions within this specific HTS code. Therefore, classification into 3921.90.29.00 relies on meeting the criteria of being a plastic plate, sheet, film, foil, or strip combined with textile material, weighing over 1.492 kg/m², and not being classifiable under the preceding sibling categories due to the textile fiber composition. Practical classification would involve examining the product's construction and performing weight analysis of the textile components.
