Import Tips
• File EPA Form 9500 for HFC import petitions; allocations required under American Innovation & Manufacturing Act
• Validate cylinder retest dates per 49 CFR 173.301; common issue is expired hydrostatically tested containers
• Declare exact purity percentage; values below 99% may trigger reclassification to mixtures
