Import Tips
• Label panels clearly as 'fiberboard' not 'insulation' to avoid confusion with Chapter 68 mineral wool products
• Maintain records of production process showing mechanical wood processing origin per subheading notes
• Test for VOC emissions if marketed for interior use to meet CARB/EPA standards
