Import Tips
• Obtain R-value certifications to support insulation claims without shifting to Chapter 68 building materials
• Ensure 'wallcovering' intent in commercial docs; construction use may trigger different rulings
• Test for mold resistance in humid climates, as CBP may inspect for agricultural risks
