Import Tips
• Verify silica content certification exceeding 93% through independent lab testing, as required for (622) statistical suffix
• Ensure documentation proves mechanical bonding and lamination processes to avoid reclassification to simpler woven fabrics
• Check for colored coating specifications; plain/uncolored versions may fall under different subheadings
