Import Tips
• Include technical data sheet confirming CAS registry number and molecular structure matching the tariff description
• Segregate from halogenated phosphorus compounds during storage/shipping to maintain non-halogenated status
• File EPA import certification for new chemical substances if not on TSCA Inventory
