Import Tips & Compliance
• Verify silica (SiO2) content exceeds 60% via lab testing to confirm classification under heading 7019; non-compliant wools shift to 6806
• Include material safety data sheets (MSDS) documenting low formaldehyde emissions for EPA compliance during customs clearance
• Avoid misclassification as building materials by specifying end-use as insulation, not structural components
