Import Tips
• Ensure the sheets are imported as raw cellular styrene sheets, not as finished architectural articles, to qualify for 3921.11.00
• Declare the polymer composition (polystyrene) and cellular structure clearly on customs documents
• Check if the relief patterns constitute 'surface-worked' beyond cutting, which may affect classification
