HS Code for Plexiglass sheets

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.

Products Included

• Clear PMMA (acrylic) sheets
• Colored or tinted plexiglass plates
• Opaque acrylic plastic sheets
• Polished plexiglass strips
• Non-cellular acrylic film

Common Misclassification

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.
