Import Tips
• Confirm the tow's filament decitex is less than 67 and twist is below 5 turns per metre to satisfy Chapter 55 Note 1
• Keep detailed production records showing the copper-ammonia process and regenerated cellulose composition for CBSA verification
• Check if the tow is drawn (incapable of stretching >100%) as required for synthetic tow, though this is artificial tow
