UN 3092 — 1-Methoxy-2-propanol
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 3092 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 3092 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 |
|---|---|---|---|---|---|---|
| 1-METHOXY-2-PROPANOL | 3 | F1 | III | 3 | 3 | 30 |
Source: ADR 2025, Table A of Chapter 3.2 · ECE/TRANS/352 Vol. I (UNECE). Class 3 is “Flammable liquids” (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 |
|---|---|---|---|
| 3 | 1 000 | × 1 | Packing group III and the listed classes. |
Source: ADR 2025, 1.1.3.6.3 and 1.1.3.6.4 · ECE/TRANS/352 Vol. I (UNECE).
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.

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.
Vessel stowage categories on this entry

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.
| 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. |
| IB3 | Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1 and 31HA2, 31HB2, 31HN2, 31HD2 and 31HH2). |
| T2 | Portable tank instruction. Minimum test pressure: 1.5 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 3092
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.
30 — flammable liquid (flash-point between 23 °C and 60 °C, inclusive) or flammable liquid or solid in the molten state with a flash-point above 60 °C, heated to a temperature equal to or above its flash-point, or self-heating liquid.
| 3 | Flammability of liquids (vapours) and gases or self-heating liquid |
| 0 | No further hazard — the first figure alone describes the hazard adequately |
Source: ADR 2025, 5.3.2.3 · ECE/TRANS/352 Vol. II (UNECE). The tunnel restriction code of column (15) is a different value and is not part of our import.
05 · Substances
Substances shipped under UN 3092
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 3092 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 3092
Source: harmonised classification, EU CLP Annex VI. Transport classification and supply classification are decided under different rules and do not have to agree.
07 · FAQ
UN 3092 — frequently asked questions
What is UN 3092?
UN 3092 is the United Nations number for 1-Methoxy-2-propanol. Under ADR 2025 it is assigned to class 3 (flammable liquids), classification code F1.
What packing group is UN 3092?
Under ADR 2025 UN 3092 is packing group III.
Is UN 3092 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 3092. Special provisions still differ and are never interchangeable between the two systems.
What is the hazard identification number for UN 3092?
The orange-coloured plate for UN 3092 carries the hazard identification number 30 above the UN number. Under ADR 5.3.2.3.2 that number means: flammable liquid (flash-point between 23 °C and 60 °C, inclusive) or flammable liquid or solid in the molten state with a flash-point above 60 °C, heated to a temperature equal to or above its flash-point, or self-heating liquid.
What is the transport category of UN 3092?
Column (15) of Table A puts UN 3092 in transport category 3. Under ADR 1.1.3.6.3 the maximum total quantity per transport unit for that category is 1 000.
Which substances ship under UN 3092?
We hold 1 substance linked to UN 3092 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.
