Import Tips & Compliance
• Import the sheets as raw, uncut sheets, not as pre-cut insulation components for specific appliances, to qualify for 3921.11.00
• Provide documentation on the extruded polystyrene composition and cellular structure
• Verify the sheets are not considered parts of appliances under Section XVI, which is excluded by chapter note 2(s)
