UN 1360 — Calcium phosphide
Table A of ADR 2025 and the 49 CFR 172.101 Hazardous Materials Table for this number, kept side by side and never merged, plus the CLP label elements of the substances that ship under it.
The two tables are never merged. The same UN number can carry a different packing group, a different proper shipping name and entirely different special provisions in each system. Every value below sits under the name of the jurisdiction it comes from.
01 · Two jurisdictions
UN 1360 in ADR 2025 and in 49 CFR 172.101
On the fields below the two tables agree for this number. Special provisions are deliberately absent from this comparison: identical code numbers mean different things in the two systems and are never interchangeable.

UN 1360 in Table A of ADR 2025
One row in Table A of Chapter 3.2. Every value below comes from that row.
| Proper shipping name (3.1.2) | Class | Classification code | PG | Labels | Transport category | Hazard ID |
|---|---|---|---|---|---|---|
| CALCIUM PHOSPHIDE | 4.3 | WT2 | I | 4.3, 6.1 | 1 | — |
Source: ADR 2025, Table A of Chapter 3.2 · ECE/TRANS/352 Vol. I (UNECE). Class 4.3 is “Substances which, in contact with water, emit flammable gases” (ADR 2.1.1.1).
Transport category and the 1 000-point exemption
Column (15) of Table A decides whether a load stays under the exemption of ADR 1.1.3.6. Quantities of different categories are added with the multipliers below, and the sum must not exceed 1 000.
| Category | Max total quantity per transport unit | Multiplier in 1.1.3.6.4 | What it means |
|---|---|---|---|
| 1 | 20 | × 50 | Packing group I and the listed classes — the exemption runs out after 20 kg or litres per transport unit. |

Not imported and therefore not shown for this number: limited quantities (column 7a), excepted quantities (7b), packing instructions (8), tank codes (10–13) and the tunnel restriction code (15). An empty section is more honest than borrowed text.

Packaging cells are section references into 49 CFR part 173: exceptions, non-bulk, bulk. Handling codes in column 10B are defined in 49 CFR 176.84, which is not part of our import — the numbers are shown as printed in the table.
Vessel stowage categories on this entry
| E | May be stowed “on deck” or “under deck” on a cargo vessel or on a passenger vessel within the 25-passenger limit; prohibited on a passenger vessel above that limit. |

Special provisions — 49 CFR 172.102
Codes from column (7) of the Hazardous Materials Table, with the text of § 172.102. These are United States provisions only and have nothing to do with the ADR codes above, even where the number is identical.
| A19 | Combination packagings consisting of outer fiber drums or plywood drums, with inner plastic packagings, are not authorized for transportation by aircraft. |
| A8 | For combination packagings, if glass inner packagings (including ampoules) are used, they must be packed with cushioning material in tightly closed metal receptacles before packing in outer packagings. |
| N40 | This material is not authorized in the following packagings: a. A combination packaging consisting of a 4G fiberboard box with inner receptacles of glass or earthenware; b. A single packaging of a 4C2 sift-proof, natural wood box; or c. A composite packaging 6PG2 (glass, porcelain or stoneware receptacles within a fiberboard box). |
| W31 | Non-bulk packagings must be hermetically sealed. |

Substances shipped under UN 1360
Linked by CAS number, never by name: a name match once produced “acetone cyanohydrin” for acetone, and a wrong link here would be a wrong classification. Each entry opens its own reference page with the CLP classification and label elements.
05 · The label side
What UN 1360 looks like on a workplace label
The tables above are the transport classification. This is the other half of the same material: the CLP label elements of the substances linked to this number — what actually goes on the drum once it has been delivered. Transport marks and supply labels answer different regulations and do not replace one another.
Hazard statements on the substances under UN 1360
| H260 | In contact with water releases flammable gases which may ignite spontaneously. |
| H300 | Fatal if swallowed. |
| H311 | Toxic in contact with skin. |
| H318 | Causes serious eye damage. |
| H330 | Fatal if inhaled. |
| H400 | Very toxic to aquatic life. |

06 · FAQ
UN 1360 — frequently asked questions
What is UN 1360?
UN 1360 is the United Nations number for Calcium phosphide. Under ADR 2025 it is assigned to class 4.3 (substances which, in contact with water, emit flammable gases), classification code WT2.
What packing group is UN 1360?
Under ADR 2025 UN 1360 is packing group I.
Is UN 1360 classified the same way in the United States and in Europe?
On the fields we hold — proper shipping name, class, packing group and label codes — ADR 2025 and the 49 CFR 172.101 table agree for UN 1360. Special provisions still differ and are never interchangeable between the two systems.
What is the transport category of UN 1360?
Column (15) of Table A puts UN 1360 in transport category 1. Under ADR 1.1.3.6.3 the maximum total quantity per transport unit for that category is 20.
Which substances ship under UN 1360?
We hold 1 substance linked to UN 1360 by CAS number. Each one has its own reference page with the CLP classification, GHS pictograms and hazard statements that apply on the label — the workplace side of the same material.
Need the plate, the labels or the placards printed?
The orange plate above is a physical article, and so are the class labels in column (5). Our sister site GHSLabels.com covers printing and suppliers. For the workplace label of the same material, use the GHS label constructor, and browse other numbers in the UN number reference.
Reference aid only. Values are reproduced from ADR 2025 and the 49 CFR 172.101 table as published; the consignor remains responsible for the classification of a specific consignment. Always verify against the current published regulation and the supplier's safety data sheet.
