Shop for baby clothes and you'll see “organic,” “pure,” and “non-toxic” on labels everywhere — but those words aren't legally protected, so they don't guarantee much on their own. Certifications are how you tell a genuine claim from clever marketing, and two names come up again and again: GOTS and OEKO-TEX. Here's what each one actually means, how they differ, and which matters most for your baby.
Why certifications matter
A baby's skin is thin, absorbent, and reactive, so whatever sits against it all day matters. The trouble is that “organic” on a label, with nothing behind it, is just a word. A trusted third-party certification does the homework for you — independently verifying how the fabric was grown, processed, or tested — so you can shop with confidence instead of taking the marketing at its word.
What is GOTS?
The Global Organic Textile Standard (GOTS) is the gold standard for organic textiles. It certifies that a fabric contains a high percentage of certified organic fibres and that the entire supply chain — from harvesting the cotton to the finished garment — meets strict environmental and social rules. That means tight limits on the chemicals used in dyeing and finishing, no toxic heavy metals or chlorine bleach, and fair conditions for workers. When you see a genuine GOTS label, it's a promise of organic integrity from farm to family.
What is OEKO-TEX Standard 100?
The OEKO-TEX Standard 100 label does a different job. It doesn't certify that a fabric is organic — instead, it tests the finished product for a long list of harmful substances and confirms it's safe for skin contact. For baby clothing, OEKO-TEX applies its strictest testing tier (Product Class I), covering every thread, button, and zip. In short: GOTS is about how the fabric was grown and made; OEKO-TEX is about what is (and isn't) in the final fabric.
GOTS vs OEKO-TEX: the key difference
| GOTS | OEKO-TEX 100 | |
|---|---|---|
| Certifies | Organic fibre + clean, ethical processing | Finished fabric tested free of harmful substances |
| Organic? | Yes | Not necessarily |
| Covers | Whole supply chain | The end product |
| Best for | Organic + eco + ethical assurance | Chemical safety against skin |
The two aren't rivals — they answer different questions, and many quality baby garments carry both.
Certification matters most on the pieces worn against the skin for the longest — everyday basics like our Knitted Baby Romper with Sailor Collar, a soft cotton one-piece for daily wear. Whatever brand you buy, checking the label for one of these certifications is the surest way to know a fabric is what it claims to be.
Which matters most for your baby?
It depends on what you care about most:
- For chemical safety against the skin, OEKO-TEX is the direct answer — it's literally a test for harmful substances in the finished fabric.
- For organic, environmental, and ethical assurance, GOTS is the stronger, broader standard.
- For the full picture, a piece carrying both gives you organic and tested-safe.
Neither is “better” in the abstract — they simply certify different things. For most parents, seeing either one is a reassuring sign; seeing both is ideal.
How to actually check a label
A few practical tips so a claim can't slip past you:
- Look for the logo and a licence or certification number — genuine certifications are traceable, not just a printed graphic.
- Be cautious with bare words like “organic” or “eco” that carry no certification behind them.
- Check the fibre content — “100% cotton” plus a certification is a strong combination.
- Remember GOTS has tiers — “organic” (95%+ organic fibre) versus “made with organic” (70%+).
The same rule applies to any everyday set, like our Baby Ribbed Outfit Set — soft, breathable cotton for daily wear, and exactly the kind of skin-contact piece where it's worth reading the label carefully before you buy.
Putting it into practice
Certifications are the tool; knowing where to spend is the strategy. Prioritise certified or tested-safe fabric for the skin-contact basics — bodysuits, sleepwear, and newborn everyday pieces — and relax about briefly-worn outer layers. When you're choosing organic cotton baby clothes, the certification is what separates a real claim from marketing.

Frequently asked questions
Is OEKO-TEX the same as organic? No — OEKO-TEX tests the finished fabric for harmful substances but doesn't certify organic farming. GOTS is the organic certification.
Do baby clothes have to be certified? No, certification is voluntary — but it's the most reliable way to verify an “organic” or “non-toxic” claim.
Which is better, GOTS or OEKO-TEX? Neither — they certify different things. GOTS covers organic and ethical production; OEKO-TEX confirms the final fabric is tested safe. Both together is ideal.
The bottom line
GOTS certifies organic fibre and clean, ethical processing across the whole supply chain; OEKO-TEX Standard 100 tests the finished fabric for harmful substances. One tells you how it was made, the other what's in it — and for a baby's delicate skin, either is a reassuring sign, while both is the gold standard. Look for the logo and licence number, prioritise the pieces worn against the skin, and you'll never have to take “organic” on trust again.
