Import Tips
• Provide manufacturer specs showing R-value or thermal resistance to substantiate heat insulating claim during customs entry
• Ensure proper marking of country of origin as misdeclaration often leads to penalties for construction ceramics
• Bundle with energy certification docs to prevent challenges on environmental claims during import clearance
