Import Tips
• Import the sheets as separate panels, not as part of lighting fixtures, to stay under 3921.11.00
• Provide technical data on the cellular structure and styrene polymer content to support classification
• Verify the sheets are not surface-worked beyond cutting into rectangles, per chapter note 10
