Import Tips
• 21700 cells require larger shipping containers; ensure packaging accommodates 21.7mm diameter without crushing
• Provide OEM automotive specifications for EV-destined cells to expedite customs review
• High-capacity cells (>300Wh) may need FAA approval for air shipment regardless of packaging
