UN 1203 — Motor spirit or gasoline or petrol
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 1203 in ADR 2025 and in 49 CFR 172.101
The two systems differ for this number on 1 of 5 fields. Special provisions are deliberately absent from this comparison: identical code numbers mean different things in the two systems.

Special provisions — ADR 2025, Chapter 3.3
Codes from column (6) of Table A, with the text of Chapter 3.3.1. These are ADR provisions only. A code with the same number exists in 49 CFR 172.102 and means something else there — the two lists are never combined.
| SP 243 | Gasoline, motor spirit and petrol for use in spark-ignition engines (e.g. in automobiles, stationary engines and other engines) shall be assigned to this entry regardless of variations in volatility. |
| SP 534 | While in some climatic conditions, petrol (gasoline) may have a vapour pressure at 50 °C of more than 110 kPa (1.10 bar) but not more than 150 kPa (1.50 bar) it is to continue to be considered as a substance having a vapour pressure at 50 °C of not more than 110 kPa (1.10 bar). |
| SP 664 | When substances under this entry are carried in fixed tanks (tank-vehicles) or demountable tanks, these tanks may be equipped with additive devices. Additive devices: - Are part of the service equipment for dispensing additives of UN No. 1202, UN No. 1993 packing group III, UN No. 3082 or non-dangerous substances during discharge of the tank; - Consist of elements such as connecting pipes and hoses, closing devices, pumps and dosing devices which are permanently connected to the discharge device of the tank’s service equipment; - Include means of containment which are an integral part of the shell, or permanently fixed to the exterior of the tank or tank-vehicle. Alternatively, additive devices may have connectors for connecting packagings. In this latter case, the packaging itself is not considered part of the additive device. The following requirements shall apply depending on the configuration: (a) Construction of the means of containment: (i) As an integral part of the shell (e.g. a tank compartment), they shall meet the relevant provisions of Chapter 6.8. (ii) When permanently fixed to the exterior of the tank or to the tank-vehicle, they are not subject to the construction provisions of ADR provided they comply with the following provisions: They shall be made of a metallic material and comply with the following minimum wall thickness requirements: Material Minimum wall thicknessa Austenitic stainless steels 2.5 mm Other steels 3 mm Aluminium alloys 4 mm Pure aluminium of 99.80 % 6 mm a For means of containment made with double walls, the aggregate thickness of the outer metal wall and the inner metal wall shall correspond to the wall thickness prescribed. Welding shall be carried out in accordance with the first paragraph of 6.8.2.1.23, except that other suitable methods may be applied to confirm the quality of the welding. (iii) Packagings which are connectable to the additive device shall be metal packagings and meet the relevant construction requirements of Chapter 6.1, as applicable for the additive concerned. (b) Tank approval For tanks equipped or intended to be equipped with additive devices, where the additive device is not included in the original type approval of the tank, the provisions of 6.8.2.3.4 shall apply. (c) Use of means of containment and additive devices (i) In case of (a) (i) above, no additional requirements. (ii) In case of (a) (ii) above, the total capacity of the means of containment shall not exceed 400 litres per vehicle. (iii) In case of (a) (iii) above, 7.5.7.5 and 8.3.3 shall not apply. The packagings may only be connected to the additive device during discharge of the tank. During carriage, the closures and connectors shall be closed so as to be leaktight. (d) Testing for additive devices The provisions of 6.8.2.4 shall apply to the additive device. However, in case of (a) (ii) above, at the time of the initial, intermediate or periodic inspection of the tank, the means of containment of the additive device shall only be subject to an external visual inspection and a leakproofness test. The leakproofness test shall be carried out at a test pressure of at least 0.2 bar. NOTE: For the packagings described in (a) (iii) above, the relevant provisions of ADR shall apply. (e) Transport document Only the information required in accordance with 5.4.1.1.1 (a) to (d) needs to be added to the transport document for the additive concerned. In this case, the remark "additive device" shall be added to the transport document. (f) Training of drivers Drivers who have been trained in accordance with 8.2.1 for carriage of this substance in tanks need no additional training for the carriage of the additives. (g) Placarding or marking Placarding or marking of the fixed tank (tank-vehicle) or demountable tank for the carriage of substances under this entry in accordance with Chapter 5.3 is not affected by the presence of an additive device or the additives contained therein. |

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.
| 144 | If transported as a residue in an underground storage tank (UST), as defined in 40 CFR 280.12, that has been cleaned and purged or rendered inert according to the American Petroleum Institute (API) Standard 1604 (IBR, see § 171.7 of this subchapter), then the tank and this material are not subject to any other requirements of this subchapter. However, sediments remaining in the tank that meet the definition for a hazardous material are subject to the applicable regulations of this subchapter. |
| 177 | Gasoline, or, ethanol and gasoline mixtures, for use in internal combustion engines ( e.g. , in automobiles, stationary engines and other engines) must be assigned to Packing Group II regardless of variations in volatility. |
| B1 | If the material has a flash point at or above 38 °C (100 °F) and below 93 °C (200 °F), then the bulk packaging requirements of § 173.241 of this subchapter are applicable. If the material has a flash point of less than 38 °C (100 °F), then the bulk packaging requirements of § 173.242 of this subchapter are applicable. |
| B33 | MC 300, MC 301, MC 302, MC 303, MC 305, MC 306, and DOT 406 cargo tanks equipped with a 1 psig normal vent used to transport gasoline must conform to Table I of this Special Provision. Based on the volatility class determined by using ASTM D 439 and the Reid vapor pressure (RVP) of the particular gasoline, the maximum lading pressure and maximum ambient temperature permitted during the loading of gasoline may not exceed that listed in Table I. |
| IB2 | Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1). |
| T4 | Portable tank instruction. Minimum test pressure: 2.65 bar; minimum shell thickness (reference steel): § 178.274(d)(2); pressure-relief requirements: Normal; bottom opening requirements: § 178.275(d)(3). See 49 CFR 172.102(c)(7)(ii), Table of Portable Tank T Codes T1-T22. |

Substances shipped under UN 1203
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.
06 · The label side
What UN 1203 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 1203
| H224 | Extremely flammable liquid and vapour. |
| H304 | May be fatal if swallowed and enters airways. |
| H340 | May cause genetic defects <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H350 | May cause cancer <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |

07 · FAQ
UN 1203 — frequently asked questions
What is UN 1203?
UN 1203 is the United Nations number for Motor spirit or gasoline or petrol. Under ADR 2025 it is assigned to class 3 (flammable liquids), classification code F1.
What packing group is UN 1203?
Under ADR 2025 UN 1203 is packing group II.
Is UN 1203 classified the same way in the United States and in Europe?
No. For UN 1203 the two tables differ on proper shipping name. Each panel on this page shows its own source; values from one system must not be carried over into the other.
What is the hazard identification number for UN 1203?
The orange-coloured plate for UN 1203 carries the hazard identification number 33 above the UN number. Under ADR 5.3.2.3.2 that number means: highly flammable liquid (flash-point below 23 °C).
What is the transport category of UN 1203?
Column (15) of Table A puts UN 1203 in transport category 2. Under ADR 1.1.3.6.3 the maximum total quantity per transport unit for that category is 333.
Which substances ship under UN 1203?
We hold 1 substance linked to UN 1203 by CAS number, 1 of which also has a full safety data sheet on this site. 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.
