Classification of plexiglass sheets under HS 3920.51

Plexiglass, the commercial name for polymethyl methacrylate (PMMA), is classified under HS code 3920.51 when it is in the form of plates, sheets, film, foil, or strip. This classification is part of Chapter 39, which covers plastics and articles thereof. Specifically, heading 3920 applies to plastic products that are non-cellular and have not been reinforced, laminated, supported, or similarly combined with other materials. The subheading 3920.51 is dedicated to acrylic polymers, of which PMMA is the most common. To qualify for this code, the sheets must not be self-adhesive and must not be further worked than surface-worked (such as polished, embossed, or colored) or cut into rectangular or square shapes. Plexiglass is valued for its optical clarity and impact resistance, and its classification depends strictly on its chemical composition as an acrylic polymer and its physical state as a solid, non-composite sheet.

Codes often confused with 3920.51

Common mistake. Plexiglass sheets are frequently misclassified under HS code 3921.13 or 3921.90. However, 3921 is reserved for sheets that are cellular (foam-like) or reinforced with other materials like fiberglass. Another common error is using 3919.10 for plexiglass that has a self-adhesive backing; self-adhesive plastic sheets must be classified under 3919. Finally, if the plexiglass has been cut into a specific shape other than a square or rectangle, it may be classified as a finished article under 3926.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
