Class 8, corrosive substances, packing group II: the UN containers that may carry it under ADR 2025, the largest of each, and its limited quantity.
UN 2079 is the Dangerous Goods List entry for diethylenetriamine (DETA): Class 8, corrosive substances, packing group II. As a single packaging it may travel in a UN jerrican of up to 60 L, a drum of up to 450 L or an IBC of up to 3,000 L, with a UN mark showing X or Y. Its limited quantity is 1 L per inner packaging.
| Proper shipping name | Class | Packing group | Limited quantity | Packing instruction |
|---|---|---|---|---|
| DIETHYLENETRIAMINE | 8 | II | 1 L | P001, IBC02 |
Class 8 covers substances that destroy skin or corrode metal (ADR 2.2.8). Packing group I is for the fastest-acting, II for the next band and III for the slowest, including liquids that corrode steel or aluminium faster than 6.25 mm a year at 55 °C.
Packing group I means high danger, II medium danger and III low danger (ADR 2.1.1.3). The group sets how strong the container must be: the UN mark shows X for packing group I, Y for II and Z for III, and a higher level covers the lower groups.
Each entry below shows the UN container types its packing instruction allows and the largest of each. Read the entry whose name matches section 14 of your safety data sheet.
| Container type | UN codes | Largest allowed | Status |
|---|---|---|---|
| Jerrican, closed head | 3A1, 3H1, 3B1 | 60 L | Permitted |
| Jerrican, removable head | 3A2, 3H2, 3B2 | 60 L | Permitted |
| Drum, closed head | 1A1, 1H1, 1B1 | 450 L | Permitted |
| Drum, removable head | 1A2, 1H2, 1B2 | 450 L | Permitted |
| Plastic receptacle in a steel drum | 6HA1 | 250 L | Permitted |
| IBC | 31A, 31B, 31N, 31H1, 31H2, 31HZ1 | 3,000 L | Permitted |
These are the sizes the packing instruction allows. The container must also resist the liquid (4.1.1.2): chemical compatibility by liquid

Yes. P001 lists plastic jerricans (3H1) for UN 2079 up to 60 L in packing group II, with a UN mark showing X or Y.
Two more rules apply. The container must resist the liquid (ADR 4.1.1.2), so check the material against the substance before you fill. A plastic drum or jerrican for dangerous goods may be used for five years from its date of manufacture (ADR 4.1.1.15); steel has no such limit.

Column 7a of ADR 2025 Table A sets 1 L for UN 2079: the most one inner packaging may hold.
Under ADR chapter 3.4, a liquid in inner packagings no larger than that figure travels under reduced rules. The combination packaging may weigh up to 30 kg gross (20 kg on a shrink-wrapped tray), and it carries the limited quantity mark in place of the hazard labels.

ADR covers road transport in Europe, and RID rail uses the same list. By sea the IMDG Code has its own Dangerous Goods List, and by air the ICAO Technical Instructions and the IATA Dangerous Goods Regulations do. The class and packing group of UN 2079 normally match across them, but the packing instructions and the limits differ, so check the list for the mode you ship by.
In the US, the Hazardous Materials Table in 49 CFR 172.101 applies, and some materials carry an NA number there in place of a UN number. US rules call a UN-marked container specification packaging.
