Import Tips
• Provide detailed chemical analysis (GC-MS, NMR) confirming purity and structure to verify classification under 2915
• Include Safety Data Sheets (SDS) and ensure proper UN packaging for corrosive acids during transport
• Avoid misclassification as aromatic acids (2904) by documenting saturated aliphatic nature
