3920.59 - Other:

This HTS category, 3920.59, encompasses plates, sheets, film, foil, and strip made from acrylic polymers, excluding those that are cellular, reinforced, laminated, supported, or otherwise combined with other materials. These items are characterized by their non-composite structure and are derived from acrylic polymers such as poly(methyl methacrylate) (PMMA) or other acrylic copolymers and terpolymers. The key defining characteristic is the material composition – primarily acrylic-based plastics in a non-composite, non-cellular form.

This classification distinguishes itself from its sibling category, 3920.51, which specifically covers products made *of poly(methyl methacrylate)*. While PMMA is an acrylic polymer, category 3920.59 is broader, including other acrylic polymers beyond PMMA. Therefore, if the acrylic polymer is something other than pure poly(methyl methacrylate), it would fall under this 3920.59 classification, assuming all other criteria of the parent heading are met.

Within this category, further subdivisions exist to refine the classification based on specific physical characteristics. The subcategory 3920.59.10.00 is designated for "Flexible" forms of these acrylic sheets, films, etc. The remaining products, which are not classified as flexible, will fall under the "Other" subcategory, indicating that flexibility is the primary distinguishing criterion for the first subdivision.
