Import Tips
• Include ASHRAE safety classification (A1 refrigerant) documentation; critical for customs verification of proper handling
• Declare exact mass percentages via HPLC certificate; small deviations can trigger reclassification to 3827.62
• Budget for additional bonding requirements due to high environmental compliance scrutiny on HFC imports
