Import Tips
• Include GC-MS analysis certificate verifying 98% minimum purity to prevent classification as mixture
• Use UN-approved drums with phosphite-specific labeling; common pitfall is incorrect flash point declaration
• For quantities >1000kg, pre-notify CBP with REACH-equivalent documentation if from EU origins
