How to Label Dry Ice Packages According to IATA Regulations in 2025

When shipping dry ice, proper labeling is not just about meeting regulatory requirements; it ensures safety during transit. As a hazardous material, dry ice (solid carbon dioxide, UN 1845) is subject to strict regulations under the International Air Transport Association (IATA). In this guide, we will walk you through how to label dry ice packages according to IATA’s latest 2025 standards, providing essential information on symbols, documentation, packaging, and common mistakes to avoid.

What Are the IATA Guidelines for Labeling Dry Ice Packages?

IATA’s Dangerous Goods Regulations (DGR) specify clear guidelines for labeling dry ice packages. Dry ice is classified as a hazardous material (UN1845) and must be handled with care to avoid potential risks such as suffocation, frostbite, or other hazards caused by its sublimation into carbon dioxide gas. Here’s a detailed breakdown of the labeling requirements.

Key Labeling Requirements for Dry Ice:

UN Number: Mark the package with “UN 1845” to identify it as containing dry ice.
Class 9 Hazardous Materials Label: Dry ice falls under Class 9, and a specific hazardous materials diamond label must be used.
Weight of Dry Ice: Indicate the net weight of the dry ice in kilograms on the label.
Proper Shipping Name: The package must display the proper shipping name: “Dry Ice” or “Carbon Dioxide, Solid.”
Cargo Aircraft Only (if applicable): If the dry ice exceeds 5.5 kg, mark the package with “CARGO AIRCRAFT ONLY” to prevent it from being transported in the passenger cabin.

General Packaging Instructions:

Dry ice must be packaged in a way that allows for the safe release of carbon dioxide gas during transit. Packaging must prevent dangerous pressure buildup while ensuring the safety of handlers and passengers. It should also be resistant to moisture or any materials that could cause a hazardous reaction.

Why Is Correct Labeling Important for Dry Ice Air Transport?

Labeling dry ice correctly is essential not just for regulatory compliance but for safety. Dry ice sublimes into carbon dioxide gas, which can displace oxygen in confined spaces, posing serious health risks to personnel and passengers if not handled correctly. Incorrect labeling can lead to mishandling, delays, and safety hazards.

Benefits of Correct Labeling:

Safety: Accurate labeling ensures proper handling, reducing the risks associated with dry ice’s hazardous nature.
Compliance: Adhering to IATA’s guidelines helps avoid fines and delays caused by improper labeling.
Efficiency: Correct labels expedite the shipping and clearance process, ensuring smooth transit for your packages.

Risks of Improper Labeling:

Penalties: Failure to comply with labeling regulations can result in fines, delays, and even the confiscation of goods.
Safety Hazards: Incorrect labeling can lead to accidents like asphyxiation, frostbite, or even explosions in extreme cases.
Shipment Delays: Improperly labeled packages may cause delays due to re-inspection or relabeling requirements.

How to Ensure That Dry Ice Packages Are Compliant with IATA Regulations?

To ensure full compliance with IATA regulations, follow these essential steps:

1. Review IATA’s Dangerous Goods Regulations (DGR)

Familiarize yourself with IATA’s Dangerous Goods Regulations, especially the sections relevant to dry ice and hazardous material shipping.

2. Proper Labeling

Ensure that the UN number (UN 1845), Class 9 hazardous material label, and weight of the dry ice are clearly marked on the package.

3. Use Approved Containers

Only use containers that are IATA-approved and designed for dry ice. These containers allow for the proper release of carbon dioxide gas while ensuring the safety of the contents.

4. Verify Package Weight

Ensure that the weight of the dry ice is within allowable limits. For passenger aircraft, the limit is 2.5 kg, while cargo aircraft may accommodate up to 5.5 kg per package.

5. Cargo Aircraft Restrictions

If your dry ice shipment exceeds the 5.5 kg limit, ensure the package is clearly labeled as “CARGO AIRCRAFT ONLY.”

Key Labeling Symbols and Requirements for Dry Ice Packages

Dry ice packages must feature several mandatory markings to comply with IATA regulations:

UN 1845 Symbol: Indicates that the package contains dry ice.
- Example: UN 1845
- DRY ICE
Class 9 Hazardous Materials Label: A diamond-shaped label that signifies miscellaneous hazardous materials.
Cargo Aircraft Only (If Applicable): For dry ice shipments exceeding 5.5 kg, this marking restricts the transport to cargo aircraft.
Weight of Dry Ice: The exact weight of the dry ice in kilograms must be marked on the package.

Label Component	Description	Importance
UN Number (UN 1845)	Identifies the hazardous material (dry ice).	Essential for identification and safety.
Class 9 Label	Diamond-shaped label for miscellaneous hazardous materials.	Required for all dry ice shipments.
Cargo Aircraft Only	Indicates that the shipment cannot be carried in passenger cabins.	Ensures compliance with air transport restrictions.
Weight of Dry Ice	Exact weight in kilograms.	Critical for safety and compliance.

Latest Trends in Dry Ice Transport and Labeling (2025)

As of 2025, several advancements are influencing dry ice transport and labeling. The focus is shifting towards sustainability, digitalization, and enhanced safety protocols. These trends aim to improve the overall efficiency and safety of transporting temperature-sensitive products, such as pharmaceuticals and perishable foods.

Key Trends:

Sustainability: Increased use of eco-friendly packaging materials and reusable dry ice containers is becoming a priority for reducing environmental impact.
Smart Labeling: The integration of RFID and QR codes for real-time tracking and temperature monitoring is growing, allowing shippers to ensure the integrity of their dry ice shipments.
Improved Handling Protocols: More rigorous handling procedures are being adopted by airlines and logistics companies to enhance the safety and efficiency of hazardous material transportation.

Frequently Asked Questions

Q1: What are the penalties for improper labeling of dry ice?

Failure to label dry ice correctly can lead to fines, delays, and goods being rejected. It is crucial to comply with IATA regulations to avoid such penalties.

Q2: What is the maximum weight for dry ice on passenger aircraft?

Passenger aircraft can only carry up to 2.5 kg of dry ice per package. If the weight exceeds this, the dry ice must be shipped on cargo aircraft.

Q3: Do I need a Shipper’s Declaration for Dangerous Goods?

A Shipper’s Declaration is only required if dry ice is used with other hazardous materials. If dry ice is used solely as a refrigerant, it does not require this declaration.

Conclusion and Actionable Insights

Correctly labeling dry ice shipments according to IATA’s 2025 regulations ensures safe, efficient, and compliant transport. By following these updated guidelines, you will avoid delays, penalties, and safety hazards while enhancing the overall efficiency of your cold chain logistics.
