Import Tips
• Verify silica content exceeds 60% to qualify as glass wool per Chapter 70 notes; provide lab test certificates
• Label filters clearly as 'glass fiber' to distinguish from synthetic or paper media and prevent reclassification
• Include HVAC system compatibility specs in documentation to avoid end-use scrutiny
