How much dry ice do I need for shipping?

The amount of dry ice needed depends on your transit time, container size, and desired temperature profile.

General Guidelines for Deep Frozen (-108°F) Shipping

Use approximately 5 to 10 pounds of dry ice for each 24 hours of transit time.

• Overnight (24 hrs): 5–10 lbs dry ice
• 2-Day: 10–20 lbs dry ice
• 3-Day: 15–30 lbs dry ice

Larger insulated containers or lower-quality insulation will require more dry ice to cover the greater surface area.

Extended Transit (Cold Packs + Dry Ice)

For a LOW-MILD FROZEN profile with extended transit (10–24 additional hours):

1. Surround product with frozen cold packs on 2–4 sides, top, and bottom
2. Place 1.5 to 5 lbs of dry ice on top of cold packs as a buffer

Important: Always fill void spaces with dunnage packaging material to improve temperature stability and reduce sublimation.
