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)
