GOTS vs OEKO-TEX: They Answer Two Different Questions
GOTS vs OEKO-TEX is the comparison every bedding brand hopes you won’t make, because the two marks answer completely different questions and only one of them is about organic anything.
Here’s the short version. GOTS certifies that the fiber was grown organically, tracks it through every stage of manufacturing, and audits how workers were treated. OEKO-TEX Standard 100 tests the finished fabric for harmful substances and stops there.
Both are real. Neither replaces the other. And a product can carry OEKO-TEX while being made from conventionally farmed cotton in a factory nobody has inspected.
Short answer: GOTS is the stronger mark and the one to look for, because it covers organic fiber, the whole supply chain, and labor conditions. OEKO-TEX Standard 100 proves the fabric was tested for harmful substances and proves nothing else. You want GOTS. OEKO-TEX on top of it is a bonus, and OEKO-TEX on its own tells you far less than the packaging implies.
What GOTS covers
The Global Organic Textile Standard is the stricter of the two, and it’s strict in a specific direction: the whole chain rather than the end product.
To carry the “Organic” label a textile has to be at least 95% certified organic fiber. There’s a second tier, “Made with Organic,” which needs 70%. That distinction matters on a label, because both use the same logo and a brand saying “GOTS certified” without saying which tier is telling you less than it sounds.
Beyond fiber, GOTS covers processing chemistry, wastewater treatment, and traceability from the farm forward. It also carries social criteria built on ILO conventions: no child labor, no forced labor, safe conditions, freedom of association, living wages.
That last part is what people miss. GOTS is partly a labor certification, which is why it’s the one to look for if the conditions in which your sheets were made matter to you as much as what’s in them.
Where OEKO-TEX stops
Standard 100 is a product test. It screens a finished textile against a list of more than 100 substances known to be harmful, including formaldehyde released by wrinkle-free finishes, heavy metals, certain dyes and pesticide residues.
If it passes, the thing you’re holding has been tested and cleared. That’s worth something, and it applies to every component: the fabric, the thread, the buttons, the label.
What it does not do is any of the following. It doesn’t require organic fiber, so conventionally grown cotton passes routinely. It doesn’t audit the factory. It says nothing at all about wages, hours or child labor. And it doesn’t track the supply chain, because it’s testing the output rather than inspecting the process.
OEKO-TEX runs separate programs that do cover some of that. STeP audits production facilities, and MADE IN GREEN combines a product test with facility auditing. Those are different marks with different names, and a Standard 100 label doesn’t imply either.
The two, side by side
| GOTS | OEKO-TEX Standard 100 | |
|---|---|---|
| What it checks | The whole chain, farm to finished garment | The finished fabric only |
| Organic fiber required | Yes, 95% for “Organic”, 70% for “Made with Organic” | No, conventional cotton passes routinely |
| Tests for harmful substances | Yes | Yes, against 100+ substances |
| Audits the factory | Yes | No, that’s a separate mark called STeP |
| Covers wages and child labor | Yes, built on ILO conventions | No |
| Tracks the supply chain | Yes | No, it tests the output |
| What it proves | How the thing was made, and by whom | That the thing you’re holding is clean |
Why brands like the confusion
Put the two side by side and the asymmetry is obvious.
OEKO-TEX Standard 100 is cheaper and faster to obtain, because you’re testing a finished product rather than restructuring a supply chain. So a brand that wants a green-sounding badge without changing where its cotton comes from has an easy option, and “OEKO-TEX certified” on a product page reads to most shoppers as “certified safe and sustainable.”
It isn’t a lie. It’s a true claim about a narrow thing, allowed to stand in for a broader one, which is the pattern our greenwashing guide keeps circling back to. We’ve made the equivalent mistake ourselves in the other direction, treating an EWG rating as though it were the EWG VERIFIED mark, and it’s the same failure: reading a specific answer as a general endorsement.
How I’d shop it
Both, when you can get them, and that’s not a cop-out. They’re complementary by design.
GOTS on the fiber tells you the cotton was grown without synthetic pesticides and the people who processed it were protected. OEKO-TEX on the finished fabric tells you nothing harmful survived into the thing on your bed. The best organic bedding brands carry both, and they’ll tell you which is which.
If you can only have one, choose by what you’re solving for. Worried about pesticides, water and labor? GOTS. Worried about a rash, a sensitive kid, or what’s in a dye? OEKO-TEX.
And read past the logo to the tier. “GOTS Organic” is 95%. “Made with Organic” is 70%. On OEKO-TEX, Standard 100 is a product test and MADE IN GREEN is the one that adds the factory.
The picks in the best organic bedding and sheets are sorted on exactly this, with the certification each brand holds named rather than implied. Every brand there has a scored profile in our brand directory.
Frequently asked questions
Is GOTS better than OEKO-TEX?
They’re not ranked, they’re different. GOTS certifies organic fiber content, full supply-chain traceability and labor conditions. OEKO-TEX Standard 100 tests the finished product for harmful substances. GOTS is broader; OEKO-TEX is a direct safety test of the item you’ll actually touch.
Does OEKO-TEX mean a fabric is organic?
No, and this is the most common misreading. OEKO-TEX Standard 100 has no organic requirement at all. Conventionally farmed cotton sprayed with synthetic pesticides can be certified, provided the finished fabric tests clean for the substances on the list.
How much of a GOTS product must be organic?
The “Organic” grade requires at least 95% certified organic fiber. A second grade, “Made with Organic,” requires 70%. Both use GOTS branding, so it’s worth checking which one a product actually holds.
Does either certification cover working conditions?
GOTS does, through social criteria based on ILO conventions covering child labor, forced labor, safety and freedom of association. OEKO-TEX Standard 100 does not. OEKO-TEX’s STeP and MADE IN GREEN programs address production facilities, but they’re separate certifications.
