Compressed Cork Insulation Sheets from Japan
These are rigid sheets made from compressed agglomerated cork particles, often used for thermal and acoustic insulation in walls and roofs. They fall under HTS 4504.10.20.00 as they are specifically classified as insulation products from compressed cork, coated or not. The material's natural properties provide excellent sound absorption and heat resistance.

Import Tips
• Verify the cork is agglomerated and compressed specifically for insulation to avoid misclassification as general cork sheets under 4504.10.10
• Provide lab test reports confirming thermal/acoustic insulation properties and coating details if applicable
• Check for binding substance content; excessive binders may shift classification to composite materials
