About this calculator
A UN number is the four-digit number that identifies a dangerous substance or group of goods in international transport — for example UN1203 for petrol, UN1202 for diesel, UN3480 for lithium ion batteries. It appears on DG declarations, package labels, container placards and bay plans, so planners, forwarders and warehouse staff often need to check "what is this UN and which class".
This tool searches a list of frequently shipped dangerous goods, based on the basic identification columns of the Dangerous Goods List in the UN Recommendations on the Transport of Dangerous Goods — Model Regulations (UNECE), which are freely available to the public. Each entry shows the proper shipping name (sometimes shortened), class or division, subsidiary hazard and possible packing groups. Type digits (full or a prefix) or a name in English, or Indonesian keywords such as "aki", "solar" or "kaporit".
What is not here: stowage categories, segregation codes, special provisions, limited quantity limits and packing instructions of the IMDG Code — those are IMO copyright and available only in the app for users with licensed data. N.o.s. entries and packing groups depend on the actual properties of the substance. Always confirm against the IMDG Code edition in force, the shipper's SDS and the carrier's acceptance rules.
Worked example
Example searches:

- UN1789 → Hydrochloric acid, class 8, PG II/III

Frequently asked questions
Is this list the same as the IMDG Code?
No. It holds only the number, name, class, subsidiary hazard and packing group from the UN Model Regulations for common entries. The IMDG Code adds sea-specific provisions such as stowage category, segregation and marine pollutant marks that are not published here.
Why does one entry have several packing groups?
The packing group (I high danger, II medium, III low) depends on the properties of the substance, such as flash point, concentration or toxicity. Entries like paint (UN1263) or n.o.s. entries can be I, II or III depending on the product; see the SDS.
My UN number is not found — does that mean it is not DG?
Not necessarily. This list holds only frequently shipped entries. The full list has more than 3,000 entries. Check the latest Dangerous Goods List or ask the shipper and the carrier.
What is the difference between class and subsidiary hazard?
The class is the dominant hazard of the goods. A subsidiary hazard is an additional hazard that must also be labelled, for example methanol class 3 (flammable) with subsidiary 6.1 (toxic).
