Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm identity as o-Tolidine matching HTS description
• Include Material Safety Data Sheet (MSDS) detailing toxicity and handling; ensure proper HAZMAT declaration for transport
• Avoid misclassification as general polyamine (2921.59.2000); specific naming requires exact match to listed compounds
