Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm classification as a ureine derivative under Chapter 29
• Ensure SDS includes stability data, as nitrate salts may trigger hazmat shipping regulations
• Avoid misclassification as inorganic nitrates (Chapter 28) by documenting organic carboxyamide function
