Import Tips

Document exact stabilizer concentration and type; must prove 'necessary for transport' per Chapter 29 note (f)

Include polymerization inhibitor certificates showing levels below 0.01% to maintain pure compound status

Avoid anti-dusting/coloring additives beyond identification needs; may trigger note (g) exclusion
