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
