Dry ice keeps samples deeply frozen, but it is itself a dangerous good: it sublimates, displaces oxygen, and is quantity-limited by every carrier. A dry-ice booking that ignores sublimation math arrives warm after one missed connection — so we do the math for the full, realistic transit time.
How we handle dry ice
- Packing Instruction 954 packaging with ventilation and UN 1845 marking, net weight declared per package
- Sublimation budget for the realistic route time, plus buffer for connections and customs holds
- Carrier-specific quantity limits checked before booking (they differ — significantly)
- Dry-ice training documentation available on request for your quality file
- Combined UN 3373 + UN 1845 handling when a frozen biological substance travels on dry ice
- Re-icing arrangements on long-haul or multi-leg routes where available
Send us the route and target temperature — we will size the dry ice, choose the shipper, and declare it correctly.
