How Do You Ship Dry Ice in 2025 Without Breaking Rules?
IATA and DOT classify dry ice as UN 1845, demanding Class 9 labels if >5 lb (2.27 kg) per parcel. Use vented coolers, mark net weight, and keep packages under 95 kPa internal pressure.
For ground courier runs, most carriers allow up to 150 lb per box if vents are present. Add an absorbent pad to capture condensation and line the lid with a one‑way membrane to release CO₂ while blocking pests.
Quick‑Fire Tips

-
Biologics: Place a 2 mm vent in the lid and log net weight on the paperwork.
-
Event Catering: Stack 1‑inch foam panels around blocks; swap every 24 h for multi‑day festivals.
