UN1845 – How Our Dry Ice Labels Comply

Companies that ship dangerous goods must comply with labeling and package preparation requirements before transporting. It’s easy to get confused about the exact label requirements and whether your packaging meets them. You don’t want to get caught using dry ice or other hazardous substances without the proper labels.

Using substandard packaging runs the risk of contravening International Air Transport Association Dangerous Goods Regulations (IATA DGR). In addition to presenting a significant health and safety risk, the use of inappropriately labeled packaging could put the reputation of your business at risk.

At Air Sea Containers, you can be sure that your label will make it to the final destination intact when you choose our high-quality labels made from pressure-sensitive, heavyweight coated paper for maximum durability. Available in rolls of 500, these sturdy label rolls are printed with fade-resistant UV inks and will withstand the many rigors of shipping.

What Is UN1845 and How Does It Apply?

Each substance that has been designated as dangerous by the IATA has been assigned a unique identifying number. UN1845 is the numeric identifier for dry ice assigned by the United Nations (UN) and the UN Committee of Experts on the Transport of Dangerous Goods.

Dry ice is the common name used to describe compressed solid carbon dioxide. It’s used as a refrigerant for goods that need to be kept cool during transport.

It’s much colder than water ice, coming in about -110oF, and has the added benefit of not leaving a residue. This extreme cold makes it dangerous to handle without protection.

Five Requirements for Labels

The UN1845 numeric identifier implies specifications for packaging and package labeling that must be met to transport packages containing dry ice safely. Labels must include five essential requirements:

UN 1845

The package must be labeled with the identifying number “UN 1845.” The letters “UN” must be included; listing only “1845” is unacceptable. All of our dry ice packaging and package labels meet this requirement.

Dry Ice

The label must clearly state either “Dry Ice” or “Carbon Dioxide Solid.” Either or both of these identifiers are acceptable. On packages of sufficient size for it to be possible, this label must be on the same side of the package as the Class 9 Hazardous Material label.

Class 9 Hazmat

The third requirement of labeling dry ice for transportation is a class 9 hazmat label. This label identifies dry ice as a “Miscellaneous Dangerous Good,” and appears as depicted in the following photograph. All packages containing dry ice that we send out are affixed with this label, as well as the pre-prepared dry ice packaging that we sell to other vendors.

Net quantity

Any package containing dry ice must also be labeled with the net quantity of dry ice contained in the package or overpack, expressed in kilograms. For instance, a package containing 11 pounds of dry ice should properly be labeled “5 kilograms” or simply “5 kg.” Air Sea Containers’ labels are compliant, with an easily identifiable space for the final weight in kilograms to be added.

Names and Addresses

The package must be clearly labeled with the name and address of both the shipper and receiver of the package. It is important that this label be completed using a durable ink, to prevent this requirement from washing away during transportation. Our labels are explicitly printed to avoid blurring or obscuring of the pre-printed portions during transportation.

We are proud to state that our packaging is sustainable, recyclable and environmentally friendly. All our packaging and labels are made in the USA.
