Import Tips
• Verify the silica content meets Chapter 70 glass definitions; non-compliant mineral wools shift to 6806
• Include technical data sheets proving roving specification (tex size, filament count) for customs verification
• Avoid misclassification as yarn by confirming no twisting; provide sizing type documentation
