“Publishing SPF test results publicly could allow sunscreen brands to market precise SPF numbers above 50, circumventing regulations in Australia and similar regions that cap SPF claims at '50+' because SPF testing is too variable to support precise numbers.”
Plain restatementAustralia (and some comparable jurisdictions) limit the highest labelled sun protection factor claim to "50+" rather than a specific number, on the basis that SPF test results are not precise enough to support exact figures. If brands were required or permitted to publish their SPF test reports, those published figures could in practice be used promotionally to communicate specific SPF values above 50.

This post's core facts check out. Australia does limit the highest sun protection factor claim on a label to "50+" rather than a precise number, and published laboratory research supports the reason given: the same sunscreen tested at different laboratories can produce quite different SPF results, and the spread gets wider as the numbers get higher. One study found a single product could have been labelled SPF 30, SPF 50 or SPF 50+ depending on which laboratory tested it. The United States is the main large market that allows specific numbers above 50, because its current rule sets no maximum. The part about publishing test results opening a backdoor for brands to advertise numbers above 50 is a reasonable concern rather than a demonstrated fact, and no evidence was found showing this has happened anywhere. It is also worth knowing that the changes the Australian regulator announced on 27 October 2026 would have brands give their SPF results to the regulator confidentially, not publish them, and the consumer group CHOICE criticised that choice.

The trace / claim to source
- Australia limits the highest SPF claim on a sunscreen label to "50+". TGA guidance records the maximum claimable value rising from 30+ to 50+ with the 2012 edition of the standard, and permits "50+" only when the mean test result reaches the stated threshold.
- Permitted Australian SPF claims are a fixed list of values rather than any number a test produces, which is why a result of, for example, 92 could not appear on an Australian label.
- SPF testing does vary substantially between laboratories. A 2025 peer-reviewed study found between-laboratory variability proportional to SPF, meaning high SPF products varied more, and concluded this variability is likely larger than expected by the public and regulators.
- An earlier peer-reviewed study found the same product, tested at different laboratories, could support claims as different as SPF 30, SPF 50 and SPF 50+.
- The United States is an outlier among major markets on this point. FDA states its current deemed final order for sunscreens contains no maximum SPF limit, which is why specific numbers above 50 appear on US labels.
- SPF numbers are measured at an application rate of 2 mg per square centimetre, which is relevant to how much real-world difference separates SPF 30 from SPF 50.
- The headline reads as though publishing test results is a live proposal. The reforms the TGA announced on 27 October 2026 would send SPF results to the regulator confidentially, and CHOICE criticised the package for not requiring public release. Publication was raised in the March 2026 consultation, not adopted in the October announcement.
- The part about brands using published results to market numbers above 50 is a prediction about future conduct, not a finding. No source was found showing that publishing test reports has produced this effect in any jurisdiction, and Australian labelling and advertising rules would continue to restrict what a brand may claim regardless of what a test report shows.
- The "because" in the claim presents test variability as the sole stated reason for the cap. Variability is well documented and is a reason regulators give, but the historical record for the 30+ to 50+ change also reflects judgements about how much additional protection higher numbers deliver, and the retrieved documents do not set out variability as the single rationale.
- "Regulations in Australia and similar regions" groups jurisdictions that differ. The EU operates through a 2006 Commission recommendation to industry rather than a binding cap of the Australian kind, and that recommendation was under revision at the time of writing.
- Whether published test reports would in practice be used to communicate specific values above 50, and whether existing advertising rules would prevent that, is an open question with no evidence on either side.
- The exact threshold and permitted claim list in the current 2021 edition of the standard could not be read directly, so the figures quoted come from TGA guidance describing the earlier edition and from the 2012 government impact statement.
- Whether the TGA's final position on publication will change as the October 2026 proposals move to further consultation and possible legislative amendment is not yet determined.
- The illustrative example of a product testing at 38 in one laboratory and 51 in another is consistent with the published reproducibility limits, but that specific pair of values was not traced to a source.
On the Australian cap: TGA guidance describing the move to the current standard records an increase in the maximum SPF that may be claimed on a label from SPF 30+ to SPF 50+, with a claim of SPF 50+ allowed only where the mean SPF test result reaches a set threshold (60 in that guidance). The 2012 government Regulation Impact Statement for the same standard change records that permitted SPF claims were limited to a fixed list of values ending at 50 and 50+. ARPANSA's consumer page states the Australian standard allows a rating of up to 50+. On test variability: a 2025 peer-reviewed study of in vivo SPF testing reports that variability between laboratories was proportional to the SPF of the products, with high SPF products showing higher variability, that variability within a single laboratory was much lower than between laboratories, and that the between-laboratory variability is likely greater than regulators and the public expect. An earlier peer-reviewed interlaboratory study reports that, for the same product, minimum and maximum measured values from different laboratories would support different label claims, giving the example of a single product that could be claimed as SPF 30, SPF 50 or SPF 50+. On the US comparison: FDA states that the deemed final order for sunscreens established by the CARES Act does not include a limit on maximum SPF, and that labelling and maximum SPF levels remain to be addressed in future orders. FDA's 2019 proposed rule would raise the maximum labelled value from the previously proposed SPF 50+ to SPF 60+, while permitting formulation up to SPF 80. On what the TGA actually announced in October 2026: reporting of the 27 October 2026 announcement describes proposals requiring brands to test the finished product rather than only the base formula, to provide results to the TGA before listing, and to retest over shelf life. The results would go to the TGA confidentially, and CHOICE publicly criticised the package for not requiring public release of SPF test results. The TGA's March 2026 consultation had raised making this information public, and had also floated replacing numbers with descriptive categories.

Ask this case
Answers come only from the case file above; nothing is added.
Does Australia really cap SPF labels at 50+?
Yes. TGA guidance shows the maximum claimable value rose from 30+ to 50+, and a label can only say 50+ if the mean test result meets a set threshold. Permitted claims come from a fixed list of values, not any number a test happens to produce.
Is it true that SPF test results vary a lot between labs?
Yes. A 2025 peer-reviewed study found that variability between laboratories grows larger as SPF increases, and this variability is likely bigger than regulators and the public expect. An earlier study found the same product could be labelled SPF 30, 50, or 50+ depending on which lab tested it.
Did the October 2026 TGA announcement actually make SPF test results public?
No. The proposals would have brands send results to the TGA confidentially, not publish them. CHOICE criticised the package for not requiring public release, which had only been raised earlier in a March 2026 consultation.
Is there evidence that publishing SPF test results has let brands advertise numbers above 50?
No. The investigation found no evidence this has happened in any jurisdiction. This part of the claim is treated as a reasonable concern about future conduct, not a demonstrated fact.
Why can US sunscreens show specific SPF numbers above 50 when Australian ones can't?
The FDA's current rule for sunscreens sets no maximum SPF limit, unlike Australia's capped system. A 2019 FDA proposal would set a maximum labelled value of SPF 60+ while allowing formulation up to SPF 80, but this was not confirmed as adopted.
