3921.90.25.50 - Other (229)

This HTS category, 3921.90.25.50, specifically classifies "Other" plates, sheets, film, foil, and strip of plastics, that are combined with textile materials and weigh more than 1.492 kg/m². The defining characteristic for inclusion here is the predominance of man-made fibers by weight within the textile component. This means that when analyzing the textile portion of the composite material, the aggregate weight of all man-made fibers must exceed the weight of any single natural or other type of textile fiber present.

This category is distinguished from its sibling, 3921.90.25.10, which covers similar composite materials but is defined by having over 70 percent by weight of plastics. Therefore, the key differentiator lies in the weight composition: 3921.90.25.50 is determined by the composition of the textile element, while its sibling is determined by the proportion of plastic.

As this is a leaf node in the HTS classification system, there are no further subcategories under 3921.90.25.50. Classification at this level requires careful consideration of both the overall weight of the product per square meter and a detailed breakdown of the textile components to confirm the predominance of man-made fibers. Practical examples could include specialized industrial fabrics, reinforced sheeting, or certain types of coated textiles where man-made fibers form the primary textile constituent and the product meets the specified weight threshold.
