Import Tips

• 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
