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
