Import Tips

• Verify purity and ester content via certificate of analysis to confirm classification as adipic acid plasticizer under Chapter 29

• Include safety data sheets (SDS) documenting non-hazardous transport to avoid DOT reclassification during customs clearance

• Avoid common pitfalls by ensuring packaging labels specify 'plasticizer use only' to prevent misclassification as general solvents
