Division 5.1 — Oxidizers
Substances that yield oxygen and so intensify the combustion of other material.
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 | Oxidizers accepted under the hazmat agreement. |
| FedEx | contract required | contract required | Oxidizers require dangerous goods approval. |
| USPS | restricted | prohibited | Oxidizers are mailable by surface only in limited quantity. |
| Amazon FBA | review required | restricted | Oxidizers 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.

The class alone does not give you a shipping paper. Send the actual product to POST /api/classify and you get the UN number, the proper shipping name, the packing group and every carrier position for that specific item.
Questions
- What is Division 5.1 — Oxidizers?
- Substances that yield oxygen and so intensify the combustion of other material.
- Does Division 5.1 — Oxidizers have a packing group?
- Yes for most entries. Packing group I is the highest danger, II medium, III low. Where an entry's packing group depends on a measured property (a flash point for Class 3, a concentration for Class 8), Classify7 asks for that figure rather than assuming one.
- Can I ship Division 5.1 — Oxidizers by air?
- UPS: contract required; FedEx: contract required; USPS: prohibited; Amazon FBA: restricted. These are published carrier defaults, not regulatory limits — a contracted shipper may hold different terms, and the regulation may permit what the carrier declines.
