3920.51.10.00 - Flexible 🖩

This HTS category, 3920.51.10.00, specifically covers flexible plates, sheets, film, foil, and strip made from acrylic polymers, with a particular emphasis on those derived from poly(methyl methacrylate) (PMMA). These materials are characterized by their noncellular structure and absence of reinforcement, lamination, or combination with other materials, meaning they are essentially pure PMMA in a flexible form. Examples include clear or colored PMMA films used for protective coverings, decorative applications, or as components in signage where flexibility is a key attribute.

This subcategory is distinguished from its sibling, 3920.51.50, which is designated for "Other" acrylic polymer sheets. While this "Other" category would encompass flexible, noncellular acrylic polymer products not specifically falling under the poly(methyl methacrylate) classification, 3920.51.10.00 is dedicated to those explicitly identified as being of PMMA. The critical differentiator here is the specific polymer composition, requiring a determination that the material is indeed poly(methyl methacrylate).

As this is a leaf node in the HTS structure, there are no further subcategories for this specific code. Therefore, classification within 3920.51.10.00 depends entirely on verifying that the goods meet the criteria of being flexible plates, sheets, film, foil, or strip of plastics, noncellular, not reinforced, laminated, supported, or similarly combined with other materials, and crucially, that they are composed of poly(methyl methacrylate).
