Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm sebacate ester composition for proper classification
• Ensure SDS includes exact ester identification; mislabeling as generic plasticizer may trigger reclassification to Chapter 38
• Check for REACH compliance if transshipping from EU, as sebacate esters have specific registration requirements
