Deep-frozen, no residue
Dry ice holds far colder than gel packs and sublimates clean — no meltwater.
Specialized Services
Dry ice shipping.
Dry ice keeps temperature-critical freight deep-frozen — and because it is solid carbon dioxide that sublimates into gas, shipping it is its own regulated discipline. We handle the packaging, documentation and routing so your cold shipment arrives intact.

Dry ice is frozen carbon dioxide (CO₂) at about −109.3°F (−78.5°C). It does not melt into a liquid — it sublimates directly into CO₂ gas — which makes it ideal for keeping food, pharmaceuticals, vaccines and lab specimens deep-frozen without leaving any residue behind. A typical insulated container loses roughly five to ten pounds of dry ice per day to sublimation, so the right quantity and packaging matter for the length of the trip.
That same sublimation makes dry ice a regulated material in transit: it is a DOT/IATA Class 9 dangerous good (UN 1845) because the gas it releases can build up pressure and displace oxygen in an enclosed space. Compliant shipping means vented, properly rated packaging, the correct labeling and documentation, and a quantity calculated to last the journey. RS Group handles all of it.
