Import Tips
• Include FTIR spectroscopy or equivalent to prove carboxylation on SBR base without prohibited extenders per note 5(b)
• Declare exact solids content (typically 40-50%) and confirm no cross-linking agents that would alter primary form status
• Watch for EU REACH compliance if transshipping; mismatched chemical passports trigger holds
