Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming 99%+ purity and chemical identity to avoid misclassification as mixtures
• Declare exact CAS number (2785-89-9) and IUPAC name on commercial invoice for customs verification
• Ensure proper HAZMAT labeling as it's a flammable liquid; common pitfall is inadequate SDS documentation
