Polystyrene Rigid Sheet from China
A noncellular, rigid sheet made from polystyrene polymer, used for signage and display fabrication. It falls under HTS 3920.30.00.00 as it is a plate, sheet, or strip of polymers of styrene, not reinforced or laminated with other materials. The polystyrene content exceeds 95% by weight, meeting the chapter's polymer classification rules.

Import Tips
• Verify polystyrene monomer content is at least 95% by weight via lab testing to confirm classification under polymers of styrene
• Ensure declaration specifies 'noncellular and not reinforced' to avoid misclassification into laminated categories
