Import Tips
• Include GC-MS purity reports; technical grade must still qualify as chemically defined under Chapter 29 note (a)
• Use UN-approved drums with nitrogen blanketing to prevent oxidation during transit
• Avoid retail packaging; bulk industrial shipments prevent shift to Chapter 38 mixtures
