Dry Ice Shipping Requirements and Regulations 2026

Dry Ice Shipping Requirements for 2026

Dry ice is classified as a hazardous material (UN 1845, Class 9 Miscellaneous Dangerous Goods) by the DOT, even though many shippers don’t realize it. Whether you’re using dry ice to keep frozen goods cold during transit or shipping dry ice as a standalone product, understanding and following the regulations is essential. Go Freight’s dry ice certified team ensures your shipments comply with all current requirements.

Why Dry Ice Is Classified as Hazmat

Dry ice (solid carbon dioxide) sublimes into CO2 gas, which can displace oxygen in enclosed spaces and create an asphyxiation hazard. In sealed containers, the gas buildup can cause pressure explosions. These risks are why the DOT requires specific handling, packaging, and labeling for all dry ice shipments, regardless of quantity.

Packaging Requirements

Dry ice must be packaged in containers that allow CO2 gas to vent — never in completely airtight packaging. The outer packaging must be sturdy enough to withstand the temperature extremes of dry ice (negative 78.5 degrees Celsius). Insulated containers, EPS foam coolers, and specialized dry ice shipping boxes are all acceptable when they meet venting requirements.

Labeling and Marking Standards

Every dry ice package must display the Class 9 miscellaneous hazard label, the UN 1845 identification number, the net weight of dry ice in kilograms, and the proper shipping name “Dry Ice” or “Carbon Dioxide, Solid.” These markings must be clearly visible and durable enough to remain legible throughout transit. Go Freight verifies proper labeling on all dry ice shipments before transport.

Quantity Limits and Vehicle Requirements

Ground transport of dry ice has specific quantity thresholds that trigger additional requirements. Shipments exceeding 200 kg per vehicle require full hazmat shipping papers, CDL drivers with hazmat endorsements, and proper vehicle placarding. Go Freight’s fleet and drivers are equipped and certified for all quantity levels of dry ice transport.

Common Industries Using Dry Ice Shipping

Industries that regularly ship with dry ice include pharmaceutical companies for vaccine and medicine transport, food distributors for frozen food and wine and spirits shipments, medical laboratories for specimen transport, catering and hospitality companies, and biotechnology firms for research materials.
