GHS Chemical Labels: BS5609 and What It Means for Australian Suppliers
The short answer
BS 5609 label requirements apply to chemical labels that must survive marine transport. Section 2 tests the base material on aluminium and HDPE, and Section 3 tests print durability, so the printer and ink form part of the certification. Digital Label Services supplies GHS label stock, printers and consumables from Green Point.

Two separate rulebooks land on the same chemical drum. Australian work health and safety law decides what the label must say, and BS 5609 decides whether that label is still readable after months at sea. Suppliers who satisfy one and assume the other is covered are the ones who get caught. More background sits in more label printing guides.
This article separates the two. First, what GHS Revision 7 and the Work Health and Safety Regulations actually require on the label. Then what BS 5609:2024 tests, why it exists at all, and the part of the BS 5609 label requirements most buyers do not realise applies to their printer rather than their label stock.
Which version of GHS applies in Australia now?
Since 1 January 2023, GHS Revision 7 must be used to classify and label hazardous chemicals in Australia, replacing GHS 3 after a transition that ran through 2021 and 2022. That date is now well past, so GHS 7 is simply the baseline for anything newly manufactured or imported.
There is a nuance worth knowing. Chemicals manufactured or imported before 1 January 2023 may remain GHS 3 labelled and need not be relabelled. The safety data sheet, however, must still comply with GHS 7. Stock in the warehouse is not the same question as the document that travels with it.
What must a GHS label actually carry?
The label content requirements sit in Schedule 9 of the Work Health and Safety Regulations 2011. Five elements do the work, and all of them have to survive the label’s service life legibly.
The required GHS label elements:
- Product identifier
- Hazard pictograms
- Signal word, either “danger” or “warning”
- Hazard statements
- Precautionary statements
Which regulations sit behind them
Part 7.1 of the regulations carries the obligations. Regulation 335 covers retailer and supplier packing, regulation 338 covers supplier labelling, and regulation 341 sets the general labelling requirement. Regulation 342 deals with containers and regulation 343 with pipe work, which is why an operating site has labelling duties even where nothing is being supplied to a customer.
Where does BS 5609 come from?
BS 5609 exists because of the International Maritime Dangerous Goods Code. The IMDG Code requires that marks on dangerous goods containers withstand immersion in the sea for three months. A standard was needed to demonstrate that a pressure-sensitive label could meet it, and BS 5609 is that standard.
The current edition, BS 5609:2024, was published on 31 December 2024. Testing covers salt spray, artificial weathering, colour fastness and water resistance. The point is not that labels get soaked occasionally. The point is that a container lost overboard must still identify what is inside it when it is recovered.
What is the difference between Section 2 and Section 3?
Section 2 tests the base material, meaning the facestock and the adhesive together, applied to aluminium and HDPE panels. It answers whether the label physically stays attached and intact. That is the part label stock suppliers quote against, and it is the part most buyers ask about.
Section 3 tests print durability. It is about the printed image, so the printer, the ink or ribbon and the print process form part of what is being certified. A Section 2 certified facestock printed with an uncertified ink combination does not produce a BS 5609 compliant label. That distinction is the single most commonly missed point in the whole subject.
How does this change how you buy chemical labels?
It changes the question from what stock do you use to what combination is certified. The BS 5609 label requirements treat facestock, adhesive, printer and ink as a system, and substituting any one of them puts the claim back on you to demonstrate. Swapping to a cheaper ribbon is exactly the kind of change that quietly breaks it.
That is also why buying chemical and ghs labels and buying the printer from separate suppliers creates a gap. Whoever supplies the label stock and materials needs to know what will print them, and whoever supplies the printer needs to know what has to survive.
Which containers cause the most label failures?
Aluminium and HDPE are the Section 2 test substrates for a reason: they represent the two extremes a chemical label meets. Metal is smooth, rigid and thermally conductive, so labels applied to a cold drum in winter can fail to bond even though the material is rated for the job. Polyethylene and polypropylene are low-energy plastics that adhesives struggle to wet out on at the best of times.
Then there is geometry. Small-diameter bottles put the adhesive under constant peel stress at the label edges, and moulded jerricans often have ribs, seams or textured panels that reduce the actual contact area to a fraction of the label footprint. Decanted and on-site containers under regulation 342 add another variable, because those labels are often applied by hand in a plant room rather than on a line.
What should you ask a supplier before ordering?
Ask which BS 5609 sections the combination has been tested against, and on which substrate. Ask whether the certification covers the specific ink or ribbon you will run, not just the facestock. Ask what container material the label is going onto, because aluminium and HDPE behave differently from steel drums and coated IBC panels.
Then be realistic about scope. Label materials, adhesives, inks and finishes should be selected according to the intended application and relevant Australian requirements. Digital Label Services supplies label stock, printers and genuine consumables and provides specialist advice, but does not certify compliance on your behalf. Discuss specific technical or regulatory requirements before production.
Where do the two BS 5609 sections differ in practice?
The split between base material and print is what decides who is responsible for what.
| Aspect | Section 2 | Section 3 |
|---|---|---|
| What is tested | The base material: facestock plus adhesive | The durability of the printed image |
| Test substrates | Aluminium and HDPE panels | The printed label on the tested base material |
| Who it constrains | The label stock supplier | The printer, the ink or ribbon and the print process |
| What it does not answer | Whether your print survives | Whether the stock stays attached |
| Typical failure mode | Adhesive lift or facestock breakdown | Image fade, wash-off or loss of contrast |
Certification applies to a tested combination, so confirm the exact facestock, adhesive, printer and ink before assuming coverage.

Frequently asked questions
Does old stock labelled to GHS 3 have to be relabelled?
Chemicals manufactured or imported before 1 January 2023 may remain GHS 3 labelled and do not need relabelling. The safety data sheet must still comply with GHS 7. Anything manufactured or imported from that date onwards must be classified and labelled to GHS 7, so the two rules can apply across one warehouse at once.
Is BS 5609 a legal requirement in Australia?
BS 5609 is a British Standard, not Australian law. It exists to demonstrate that a label meets the IMDG Code requirement for marks on dangerous goods containers to withstand three months of sea immersion. Shippers, carriers and customers commonly specify it contractually, which is why it functions as a practical requirement for marine-bound chemical product.
Can I use a BS 5609 facestock with any printer?
No. Section 3 tests print durability, so the printer, ink or ribbon and the print process are part of what is certified. A Section 2 certified facestock printed with an untested ink combination does not deliver a certified label. Confirm the whole combination with your supplier rather than the material alone.
What signal words does GHS use?
Only two. The signal word is either danger or warning, and it is chosen by the classification rather than by preference. It sits alongside the product identifier, hazard pictograms, hazard statements and precautionary statements, which together make up the label content required under Schedule 9 of the Work Health and Safety Regulations 2011.
Which regulations cover labelling of containers on site?
Part 7.1 of the Work Health and Safety Regulations 2011 carries them. Regulation 341 sets the general labelling requirement, regulation 342 deals with containers and regulation 343 with pipe work. Regulation 335 covers retailer and supplier packing and regulation 338 covers supplier labelling, so obligations exist at both supply and use.
What edition of BS 5609 is current?
BS 5609:2024, published on 31 December 2024. It covers printed pressure-sensitive adhesive coated labels for marine use, including requirements for label stock, and its testing includes salt spray, artificial weathering, colour fastness and water resistance. Check that any certification you are shown references the edition rather than an older one.
