Import Tips
• Confirm that the insulation board is not coated or impregnated with any substance, as this would exclude it from heading 48.07
• If the board is used specifically for thermal insulation, check whether it might be classified elsewhere based on its composition
• Maintain records showing the adhesive bonding of flat layers to justify classification under 4807.00.00
