Import Tips

Document stabilizer as 'necessary for preservation' per Chapter 29(f); commercial purpose additives risk reclassification

Label with exact composition; CBP may test to confirm malononitrile remains principal component

Monitor import volumes; frequent small shipments may trigger scrutiny for retail intent (Chapter 38 risk)
