Import Tips
• Prove predominant glass content (fused silica compliant) dominates over basalt for Chapter 70 retention
• Mechanical bonding certification prevents shift to mineral wool categories under Chapter 68
• Test for glass wool specs per 7019 notes if fibrous structure approaches wool definition
