Import Tips
• Include distillation process certificates and GC-MS analysis to confirm chemical identity and purity
• Verify no added functional groups that would reclassify under oxygen-function amine headings like 2922
• Package in UN-approved drums; declare exact stabilizer content to comply with Chapter 29 note (f)
