Import Tips
• Verify silica content exceeds 60% to confirm glass wool classification per Chapter 70 notes; include manufacturer specs in documentation
• Ensure facing material (e.g
• foil) doesn't alter primary glass wool composition
• Common pitfall: mislabeling as mineral wool, which shifts to 6806
