Shipping Dry Ice From Miami: A 2026 Guide

To ship dry ice from Miami, treat it as a regulated hazardous material (UN 1845, Class 9): use vented packaging that lets CO2 gas escape, mark the net weight of dry ice on the package, apply a Class 9 label, and book a hazmat-certified carrier. Because dry ice sublimates into CO2 gas, sealed containers can rupture, so ventilation and correct documentation are essential.

Why dry ice is regulated

Dry ice is frozen CO2 at about -109F, ideal for keeping pharma, seafood, and perishables frozen. It is classed as a miscellaneous dangerous good by IATA (air), IMDG (ocean), and DOT (ground). See our pharma logistics and refrigerated services.

Packaging and labeling

Use insulated but vented packaging (never airtight). Mark “Dry Ice” or “UN 1845” and the net quantity in kilograms, and apply the Class 9 label. For air freight, IATA caps dry ice per package and requires it on the air waybill.

Plan for sublimation

Estimate roughly 5-10 lbs lost per 24 hours depending on insulation, so enough remains at delivery. For long transit, pair dry ice with a cold-chain plan and expedited freight.

Frequently asked questions

Is dry ice considered hazmat?

Yes. Dry ice is UN 1845, a Class 9 dangerous good, regulated by IATA, IMDG, and DOT, requiring proper packaging, marking, and labeling.

How much dry ice can I ship by air?

IATA limits the quantity per package and it must be declared on the air waybill. A hazmat-certified carrier confirms the current limit for your lane.
