A dry ice label should be prepared for the actual transport category and carrier requirements. Identify the route, contents and any applicable exceptions before copying a template. Then check that the final package markings, dry-ice mass and shipping information agree.
Establish the shipment category first
Separate commercial cargo, postal shipments and passenger baggage. Also identify whether the contents have their own dangerous-goods requirements. A generic Class 9 template is not automatically the correct instruction for every dry-ice use.
For applicable US air shipments, 49 CFR 173.217: carbon dioxide, solid addresses net-mass marking, operator arrangements and conditional documentation or other exceptions. Review the relevant conditions with the operator rather than assuming that a small mass eliminates every requirement.
Prepare the data before printing
| Input | Check before producing the label |
|---|---|
| Contents and transport category | The applicable operator checklist has been identified. |
| Dry-ice identity | The shipment actually contains solid CO₂. |
| Net mass | The amount to be offered is measured and uses the required units. |
| Package count | Each package is identified consistently with shipment records. |
| Names and addresses | Details required for the category are complete and current. |
Treat marks, hazard labels and documents as different items on the acceptance checklist. Do not put every piece of text inside a hazard diamond or assume one printed sticker completes all required steps.
Inspect the label on the completed package
- Required information is readable after the package is closed.
- The attachment remains secure on the actual surface and expected exposure.
- Tape, straps or other components do not hide required information.
- The accepted label dimensions and presentation are maintained.
- The final package agrees with the shipment information.
- Gas-release features have not been obstructed during closure or label placement.
Check attachment using the actual outer surface. Moisture, rough texture and changes in handling can affect adhesion. A print proof on an office desk is not evidence that the label remains readable on the shipped package.
Review overpacks and changes separately
If packages are placed inside an overpack, apply the current requirements for that configuration and check whether required information remains visible. Do not copy a total-mass instruction without confirming how the operator expects the overpack to be identified.

Frequently asked questions
Is a UN1845 sticker a complete shipping approval?
No. The applicable category also controls packaging, operator acceptance and any required information or documents.
Can a passenger use this cargo checklist unchanged?
No. Passenger baggage has its own requirements; use the appropriate airline and FAA guidance.
Should I use a fixed label-size rule from an old article?
Use the current applicable specification and carrier checklist, including any permitted exceptions.
Keep this checklist with the right guide
Use the dry ice marking scope guide to establish applicability and the US passenger baggage guide when traveling with a cooler. This article covers preparing and inspecting the final marked package.
