Import Tips
• Include third-party assay certificates verifying ≥99% purity; lower purity risks 2917.39.9000 classification
• Specify 'technical grade - not for food contact' on documentation to avoid FDA import alerts
• Use nitrogen-blanketed containers to prevent oxidation; degraded product may be rejected at entry
