Flame Retardant PMMA Signage Sheet

Rigid poly(methyl methacrylate) sheets formulated with flame retardant additives for use in indoor signage and display panels. These non-flexible sheets fall under HTS 3920.51.5050 due to their acrylic polymer composition, specifically poly(methyl methacrylate), and inclusion of flame retardants. They are noncellular and not reinforced or laminated with other materials.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3920Same rate: 41.5%

If containing less than 95% methyl methacrylate monomer

Sheets of other acrylic polymers not predominantly poly(methyl methacrylate) fall under the broader acrylic polymers subheading.

3921.90.11.00Lower: 39.2% vs 41.5%

If worked or further processed like cut-to-size or printed

Plates, sheets, etc., of plastics that are worked (e.g., shaped, engraved) are classified in heading 3921 as other plates and sheets.

3920.99.50.00Lower: 40.8% vs 41.5%

If made from other non-acrylic polymers like polycarbonate

Rigid noncellular sheets of other plastics without specific polymer provisions go to the 'Other' subheading in 3920.99.

Import Tips & Compliance

Verify flame retardant content via lab testing and provide certificates to Customs as these sheets must meet specific subheading criteria

Label sheets clearly with PMMA composition and flame retardancy standards (e.g

UL 94) to avoid reclassification during inspection

Check for any reinforcement or lamination that could shift classification to 3920.52 or 3921
