UN 1230 — Methanol
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 1230 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.

UN 1230 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 |
|---|---|---|---|---|---|---|
| METHANOL | 3 | FT1 | II | 3, 6.1 | 2 | 336 |

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 |
|---|---|---|---|
| 2 | 333 | × 3 | Packing group II and the listed classes. |

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 279 | The substance is assigned to this classification or packing group based on human experience rather than the strict application of classification criteria set out in ADR. |

Carriage provisions — CV codes

| CV28 | Must be segregated from foodstuffs, other consumables and animal feed (7.5.4). · relevant to segregation on the vehicle |

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.
03 · United States
UN 1230 in the 49 CFR 172.101 Hazardous Materials Table
2 separate rows in the Hazardous Materials Table. Where the rows differ only by the symbol in column (1), that symbol is what tells them apart — “D” is domestic-only, “I” is international.
| Symbols (1) | Proper shipping name (2) | Class (3) | PG (5) | Labels (6) | Packaging (8) | Quantity limits (9) | Vessel stowage (10) |
|---|---|---|---|---|---|---|---|
| + I | Methanol | 3 | II | 3, 6.1 | §173.150 · §173.202 · §173.242 | 1 L passenger 60 L cargo | B · 40 |
| D | Methanol | 3 | II | 3 | §173.150 · §173.202 · §173.242 | 1 L passenger 60 L cargo | B · 40 |
Source: 49 CFR 172.101 Hazardous Materials Table · eCFR, revision 2026-08-03. Class 3 is “Flammable and combustible liquid” (49 CFR 173.2). 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.
What the column (1) symbols mean
| + | Fixed entry. The plus sign fixes the proper shipping name, hazard class and packing group for that entry without regard to whether the material meets the definition of that class, packing group or any other hazard class definition. |
| D | Domestic only. A proper shipping name appropriate for describing materials for domestic transportation but which may be inappropriate for international transportation under IMO or ICAO provisions. |
| I | International. A proper shipping name appropriate for describing materials in international transportation. An alternate proper shipping name may be selected when only domestic transportation is involved. |

Vessel stowage categories on this entry
| B | May be stowed “on deck” or “under deck” on a cargo vessel and on a passenger vessel carrying not more than 25 passengers (or one per 3 m of vessel length); “on deck only” on passenger vessels 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.
| IB2 | Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1). |
| T7 | Portable tank instruction. Minimum test pressure: 4 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. |

04 · Orange plate
The orange-coloured plate for UN 1230
The upper half of the plate carries the hazard identification number, the lower half the UN number. Dimensions follow ADR 5.3.2.2.1: 400 × 300 mm, black border and dividing line 15 mm, figures 100 mm high.
336 — highly flammable liquid, toxic.
| 3 | Flammability of liquids (vapours) and gases or self-heating liquid |
| 3 | Flammability of liquids (vapours) and gases or self-heating liquid · doubled figure — intensification of that hazard |
| 6 | Toxicity or risk of infection |

05 · Substances
Substances shipped under UN 1230
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 1230 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 1230
| H225 | Highly flammable liquid and vapour. |
| H301 | Toxic if swallowed. |
| H302 | Harmful if swallowed. |
| H311 | Toxic in contact with skin. |
| H317 | May cause an allergic skin reaction. |
| H319 | Causes serious eye irritation. |
| H331 | Toxic if inhaled. |
| H370 | Causes damage to organs <or state all organs affected, if known> <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |

07 · FAQ
UN 1230 — frequently asked questions
What is UN 1230?
UN 1230 is the United Nations number for Methanol. Under ADR 2025 it is assigned to class 3 (flammable liquids), classification code FT1.
What packing group is UN 1230?
Under ADR 2025 UN 1230 is packing group II.
Is UN 1230 classified the same way in the United States and in Europe?
No. For UN 1230 the two tables differ on rows in the table. 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 1230?
The orange-coloured plate for UN 1230 carries the hazard identification number 336 above the UN number. Under ADR 5.3.2.3.2 that number means: highly flammable liquid, toxic.
What is the transport category of UN 1230?
Column (15) of Table A puts UN 1230 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 1230?
We hold 2 substances linked to UN 1230 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.
