Division 2.2 — Non-flammable, non-toxic gas
Compressed, liquefied and refrigerated gases that are neither flammable nor toxic.
Carrier acceptance
The published default for this class. A UN-specific rule can override it — lithium batteries and dry ice are both Class 9 and are treated quite differently.
| Carrier | Ground | Air | Position |
|---|---|---|---|
| UPS | contract required | contract required | Non-flammable compressed gases accepted under the hazmat agreement. |
| FedEx | contract required | contract required | Non-flammable gases require dangerous goods approval. |
| USPS | restricted | prohibited | Non-flammable compressed gases are mailable by surface only, within Publication 52 quantity limits. |
| Amazon FBA | review required | restricted | Non-flammable gases accepted after dangerous goods review. |
Carrier positions encode each carrier's published default as of the ruleset date. Tariffs change more often than regulations, and a contracted shipper may hold different terms — confirm against the carrier's current guide before the first shipment of a new item.
