SPF50+ means a measured 50 in Korea and a measured 60 in the EU

One bulk, three different numbers

Sun care sourcing calls tend to open with "how high can you get the SPF?". The number that ends up on the cap, though, is decided by the destination's labelling rules, not by the formulator. Send the same bulk to three markets and three different figures get printed.

Korea's Regulation on the Review of Functional Cosmetics requires every sun protection factor of 50 or above to be written as "SPF50+". A product measuring 52 and a product measuring 85 are indistinguishable on a Korean shelf. That is also why you see Korean products slipping a figure like 100 into the product name — it cannot go in the SPF field.

Europe and Australia place the same 50+ one step higher. The category table in Commission Recommendation 2006/647/EC assigns a measured 50 to 59.9 to 50 under "high protection", and reserves 50+ and "very high protection" for a measured 60 or above. The TGA table does the same: 30 to 59 becomes 30, 40 or 50, and only 60 or higher earns 50+. A European 50+ is a tougher product than a Korean one.

A Korean label may understate the measurement

There is a second wrinkle. The Korean rule truncates the mean to an integer and then lets you label any integer down to 20% below it. A product whose mean comes back at 23 can legally be labelled anywhere from 19 to 23.

For a buyer that means the label figure and the test report figure are not necessarily the same number. If your destination files the original report, ask for the measured mean rather than reading the sample box. Planning a relabel off the printed number skips a step.

PA++++ is not a European pass

UVA is measured on different scales entirely. Korea and Japan use PA grades, Europe uses a ratio to SPF, and the US uses a wavelength. Korea's measurement standard truncates the UVA protection factor to an integer, then groups 2 to under 4 as PA+, 4 to under 8 as PA++, 8 to under 16 as PA+++, and 16 and above as PA++++.

That leaves a gap worth knowing. The EU recommends a UVA protection factor of at least one third of the labelled SPF, so a 50+ label calls for roughly 16.7. The floor for PA++++ is 16. On the grade table it is the top tier and reads like a pass, yet a product measuring 16.0 to 16.6 falls under the recommended line. For European conversations, ask for the measured UVA protection factor, not the grade.

The line that is missing from a Korean dossier

The item that goes missing most often is the critical wavelength. Korea's measurement standard has no critical wavelength section at all, so a product that has cleared a Korean functional review still carries no such figure. The US, meanwhile, classifies a mean critical wavelength of 370 nm or greater as broad spectrum protection, and the EU recommendation names the same 370 nm.

Translate a Korean functional dossier as it stands and the UVA line comes up short. You will need to book one in vitro UVA test, and that belongs in the quote and the timeline. The flip side is that the US does not ask for a human test on that item, so sequencing the work deliberately cuts the number of panels you pay for.

Water resistance does not port either. Korea runs two 20-minute immersions for "water resistant" and four for "very water resistant", and the claim needs the water-resistance ratio's confidence interval to sit at or above 50%. The US permits exactly two statements, 40 minutes and 80 minutes. Converting a Korean report into US wording is usually slower than designing the test to the US protocol from the start.

Four lines to collect at quotation stage

With sun care it is the testing, not the bulk cost, that moves the schedule. You can see where sun care sits by price band in today's ingredient signal, and match size and price combinations in the product planner. When you talk to the factory, ask for these four lines instead of the label:

• the measured SPF mean (the report's mean, not the label figure)
• the measured UVA protection factor (the number, not the PA grade)
• whether the critical wavelength was measured, and its value
• the water-resistance test design (how many immersions, how long)

In short

• Korea labels anything at SPF 50 or above as SPF50+, while the EU recommendation and the Australian categories reserve 50+ for a measured 60 or above.
• A bulk measuring 55 prints as 50+ in Korea and as 50 in Europe and Australia. Plan the relabel after you have the measured mean.
• Korea's labelling rule allows any integer down to 20% below the mean, so the label and the report can differ.
• The floor for PA++++ is a UVA-PF of 16, and the EU line for a 50+ label is about 16.7. Check the measured value, not the grade.
• Korea's measurement standard has no critical wavelength item, so a US Broad Spectrum claim and the EU UVA statement each add an in vitro test.
