Import Tips
• Conduct burst strength interpolation for weights between table values to support 4804.11 compliance
• Document absence of binders beyond kaolin to stay in 4810.39; other coatings may shift headings
• Declare exact grammage and fiber process to distinguish from semichemical or straw pulp alternatives
