Import Tips
• Include DSC (differential scanning calorimetry) test results showing distinct melt peaks for sheath vs core in CBP documentation
• Label shipments clearly as 'thermal bonding bi-component' to prevent confusion with standard polyester tow or staple
• Watch for denier variance; fibers >20D risk reclassification if not proven as staple-cut for bonding use
