Supply label · transport label
GHS labels and transport labels
Two label systems, two sets of artwork, two legal bases. They look similar enough that people assume one replaces the other — and then ship a drum carrying the wrong diamond.

Label builder
Opens set to EU CLP. You can change the jurisdiction inside the tool at any point — the label is rebuilt against the rules of whichever one is selected.
Start from a substance
No substance selected
The label below is empty and ready. Pick a substance to fill the classification in, or type your own product name straight into the tool.
Where the product is sold or used
The label must be in the official language of the country where the product is placed on the market (Art. 17(2)). More than one language is allowed if all of them carry the same information.

Primary label language
Why is Irish not in this list?
Irish cannot be the primary language here. The H and P statement texts exist in Irish — they are printed inside the multilingual tables of CLP Annexes III and IV — but the signal word does not: signal words live in the Annex I tables, and no consolidated CLP text has ever been published in Irish. A signal word is a mandatory label element under Art. 17(1)(d), so an Irish-primary label would be missing one. Irish is still available as the second language. For Ireland, English-primary + Irish-second is what this tool can produce lawfully.

Container & label size
Container capacity
EU CLP: for ≤ 3 L Table 1.3 asks for if possible, at least 52 × 74 mm — a target for this tier, not a minimum and each pictogram at least 10 mm, 16 mm if possible
Label size
101.6 × 50.8 mm is under the 52 × 74 mm that Table 1.3 asks for (short by 1.2 mm on the short side). This is not a breach. For packages not exceeding 3 litres the wording is “if possible, at least 52 × 74” — a target, not a minimum. Where it cannot be met, Art. 29(1)–(2) and Annex I §1.5 apply (tie-on tag, outer packaging, or a reduced set).

CLP Art. 32(1) — pictograms, signal word and hazard statements are grouped together
01 · The difference
Two systems that happen to both use diamonds
The GHS supply label tells the person who opens the container what the chemical does to them: hazard class, signal word, hazard statements, precautions. Its diamond is red-bordered, white-filled, with a black symbol.
The transport label tells everyone handling the package in transit what it does in an accident: class, division, UN number, packing group. Its diamond is coloured by class — orange for explosives, red for flammable liquids, green for non-flammable gases — with the class number in the bottom corner. It comes from ADR in Europe and from 49 CFR in the United States, not from CLP or HazCom.
They are not alternatives. A drum of acetone going to a customer needs both: the CLP or HazCom label because it is a chemical being supplied, and the class 3 transport label because it is being carried on a road.
02 · Where they overlap
Article 33 — when one diamond can be dropped
CLP Article 33 deals with the case where a package carries both. Where an outer packaging carries a transport label for a given hazard, the CLP pictogram for the same hazard need not be shown on that outer packaging. Where the inner packaging is labelled under CLP and the outer packaging under transport rules, the CLP label on the inner packaging still has to be visible or the outer packaging has to carry it too.
This is a relief from duplication, not permission to replace the supply label with a transport label. The hazard statements, signal word and precautionary statements are unaffected.

03 · Getting the transport data
UN number, class and packing group
This site holds every UN number in Table A of ADR 2025 — 2,347 of them — with the proper shipping name, class and packing group. 389 have a full page carrying the United States entry from the 49 CFR 172.101 Hazardous Materials Table beside the ADR one, never merged into a single row, because the same number can carry a different packing group and entirely different special provisions in each system.
Those pages also generate the orange plate, and list the CLP label elements of the substances that ship under the number — which is where the two systems meet on one screen.
04 · What this tool does not do
It does not draw transport labels
The constructor on this page builds supply labels — CLP, HazCom, WHMIS, GB CLP. It does not produce ADR or DOT hazard labels, placards or orange plates. Use the UN number pages for the transport side.
Language on this label
Set by the market you sell into
The label must be in the official language of the country where the product is placed on the market (Art. 17(2)). More than one language is allowed if all of them carry the same information.
The official wording of hazard statements is fixed in CLP Annex III and of precautionary statements in Annex IV, in all 24 EU languages; the United States uses the texts of 29 CFR 1910.1200 Appendix C, which are not identical. Statement texts are never paraphrased.
Questions
Frequently asked
Is a GHS label the same as a transport label?
No. The GHS supply label comes from CLP, HazCom or WHMIS and describes the hazard to the person using the chemical. The transport label comes from ADR or 49 CFR and describes the hazard in transit. The artwork differs: GHS pictograms are red-bordered diamonds on white, transport labels are coloured by class and carry the class number.
Do I need both on a drum?
Usually yes. A hazardous chemical being shipped is both a supplied product and a dangerous good. CLP Article 33 removes the duplication only for the pictogram of the same hazard on the outer packaging, not for the rest of the supply label.
Which one goes on the outer box?
The transport label. Under CLP Article 33, if the outer packaging carries a transport label for a hazard, the CLP pictogram for that same hazard need not be repeated there. If the inner packaging carries the CLP label and it is not visible through the outer packaging, the outer packaging must carry it as well.
Where do I find the UN number for my substance?
Use the UN number reference on this site. It carries every entry in Table A of ADR 2025 with proper shipping name, class and packing group, and 389 of them have a full page that also shows the US 49 CFR 172.101 entry.
