Import Tips

Verify purity levels and provide chemical analysis certificates to confirm classification as a separate chemically defined compound under Chapter 29

Include Safety Data Sheets (SDS) documenting handling as flammable liquid; ensure DOT-compliant packaging for transport

Avoid misclassification as petroleum derivative (Chapter 27) by proving synthetic origin through manufacturing documentation
