Import Tips
• Verify silica (SiO2) content exceeds 60% via lab certification to confirm glass wool status per chapter note
• Include R-value documentation and fire ratings (ASTM E84) for customs clearance and building code compliance
• Avoid classifying as mineral wool under 6806 if alkaline oxides exceed limits; request binding ruling if borderline
