GOTS vs OEKO-TEX for Kids Clothes: 2026 Buyer's Guide

GOTS vs OEKO-TEX for Kids Clothes: What Each Certification Covers

What GOTS covers

The Global Organic Textile Standard (GOTS) is a process certification. A facility or product carrying a valid GOTS licence has been audited across the full production chain, from organic fibre farming through ginning, spinning, dyeing, finishing, and final assembly. The standard is maintained by Global Standard gGmbH, a non-profit based in Germany, and the full text of the standard is published at global-standard.org.

The GOTS Annual Report 2024 records 13,549 GOTS-certified facilities across 84 countries. India holds the largest single-country share with 3,699 certified facilities, followed by Bangladesh and Turkey. According to the published standard, GOTS covers the following areas:

• Organic fibre content. Products labelled "organic" must contain a minimum of 95% certified organic fibres. Products labelled "made with organic" must contain at least 70%. The remaining non-organic content must meet additional restrictions on fibre type and source.
• Chemical restrictions throughout processing. Substances on GOTS's restricted list are prohibited at every processing stage, not only in the finished product. This includes azo dyes that can release carcinogenic amines, formaldehyde, chlorinated solvents, and specific heavy metals.
• Environmental criteria. Wastewater treatment at certified sites must meet specified parameters. Certified operators are required to document energy and water consumption and implement waste management systems.
• Social criteria. The standard references the International Labour Organization's core conventions covering freedom of association, no forced labour, no child labour, wages, working hours, discrimination, and workplace health and safety.
• Traceability. Certified operators must maintain records that allow a finished product to be traced back through each stage of the supply chain. Transaction certificates document the chain of custody for any organic-fibre claim.

Certification is issued by independent third-party certifiers accredited by Global Standard gGmbH. Licences are valid for twelve months and renewed through annual on-site audits. For a broader look at how different fibres behave in Indian weather, our guide to cotton-linen blends for kids covers breathability and care.

A note from the founder: When I started Mom and Zoey, the gap between a label saying "organic cotton" and what that actually means in production was the thing that surprised me most. Reading the GOTS and OEKO-TEX standards in full made it clear that they answer different questions. A brand saying "organic" without a verifiable licence number usually means something much narrower than either standard requires. That is the main reason I wanted this guide to exist as a factual reference, not a marketing pitch.

What OEKO-TEX Standard 100 covers

OEKO-TEX Standard 100 is maintained by the International Association for Research and Testing in the Field of Textile and Leather Ecology, commonly referred to as the OEKO-TEX Association. The full standard is published at oeko-tex.com. Unlike GOTS, Standard 100 is not a process audit. It is a finished-product chemical test.

An article carrying a valid Standard 100 label has been tested against a published catalogue of substances that the standard considers harmful. According to the OEKO-TEX Association's 2025 test catalogue, the list covers more than 1,000 regulated and unregulated substances, including:

• Formaldehyde, often used in wrinkle-resistant finishes
• Azo dyes that can release restricted aromatic amines
• Heavy metals, including lead, cadmium, chromium, and nickel
• Pesticide residues that may remain from fibre growing
• Phthalates used as plasticisers in prints and trims
• Organotin compounds
• Chlorinated phenols
• Allergenic disperse dyes
• Volatile organic compounds
• PFAS (per- and polyfluoroalkyl substances, often referred to as "forever chemicals")

Every component of the article must individually pass the test. That includes the main fabric, sewing thread, zippers, buttons, labels, prints, and any decorative elements. A garment is only Standard 100 certified if all of its parts meet the thresholds for the class it is certified at.

Standard 100 uses a four-tier product class system:

• Class I applies to articles intended for babies and toddlers up to 36 months of age. It uses the strictest thresholds, reflecting the fact that young children have thinner, more permeable skin and are more likely to place clothing in their mouths.
• Class II applies to articles with direct skin contact.
• Class III applies to articles with no direct skin contact.
• Class IV applies to decorative materials such as curtains and upholstery fabrics.

Standard 100 does not require organic fibre content, and it does not audit labour or environmental practices at the factories where the product was made. A fully conventional-cotton article can hold a valid Standard 100 certificate as long as its finished form passes the chemical test. Certification is issued for twelve months and must be renewed through independent laboratory testing. A separate standard, STeP by OEKO-TEX, exists for factory-level environmental and social audits.

GOTS and OEKO-TEX, side by side

A direct comparison of what each certification covers, based on the two standards as published. The rows below are drawn from the GOTS Standard v7.0 documentation and the OEKO-TEX Standard 100 test catalogue.

The two standards are not direct substitutes. GOTS tells you something about how a product was made, from farm to finished item. OEKO-TEX Standard 100 tells you something about what the final product contains when tested in a laboratory. A product can carry both certifications, a product can carry either, and a product can carry neither.

Where each certification applies in the supply chain

Mapped against the five main stages of cotton textile production, GOTS covers every step from farm to finished garment, while OEKO-TEX Standard 100 applies at the end of the chain, to the finished item.

The industry context, in numbers

A few figures from published industry reports and standard-body publications that are worth knowing before making any decision about kids clothing certifications in India.

India's position in the global organic cotton market is a large part of why these certifications are so visible in the Indian kidswear category. According to The Roundup's 2025 organic cotton statistics, India produces roughly 38% of the world's organic cotton by volume, more than any other country. The Ministry of Textiles, Government of India, has reported steady growth in certified organic cotton production over the past five years, supported by initiatives such as Paramparagat Krishi Vikas Yojana (PKVY) that help farmers transition from conventional to organic cultivation.

How OEKO-TEX Standard 100's class system works

Standard 100 applies different chemical thresholds depending on how close a product is expected to be to skin, and how vulnerable that skin is. Class I is reserved for items worn by babies and toddlers up to 36 months, and uses the strictest limits on substances such as formaldehyde, heavy metals, and allergenic dyes. Classes II through IV apply successively looser thresholds.

If an item is marketed for young children but only carries Class II or Class III certification, that means it was not tested against the Class I thresholds. Whether that distinction matters for a specific purchase depends on the item, the child's age, and how the garment will be used.

Which certification matches your priority?

Parents end up looking at these certifications for different reasons. The tool below is not a recommendation engine. It maps three common concerns to what each certification actually does, so you can see which covers the question you are asking.

Why fabric matters for young children's skin

The reason these certifications exist for children's clothing at all comes down to paediatric dermatology basics. Children's skin is thinner and more permeable than adult skin, which matters both for how easily external substances cross the skin barrier and for how readily the skin reacts to irritants and friction. For parents whose children have seasonal sensitivities, our guide to organic clothing and seasonal allergies covers this in more detail.

For a broader look at how fabric choice affects children in the Indian climate, our guide to choosing the right fabric for kids covers breathability, weight, and care routines in more detail.

How to verify a certification before you buy

Both GOTS and OEKO-TEX publish licence numbers that anyone can look up. A certification claim without a verifiable number is not substantiated. The process takes about two minutes for either standard.

1. Find the number on the label. A GOTS licence displays the certifier's logo alongside a licence number. OEKO-TEX Standard 100 labels display a test number and the issuing institute.
2. Open the public database. For GOTS, go to global-standard.org and use the certified suppliers database. For OEKO-TEX, go to oeko-tex.com and use the label check tool.
3. Enter the number and verify validity. Both databases return the current status of the licence, the certified scope, and the expiry date. An expired or invalid number is a flag that the certification claim needs follow-up.
4. Ask the brand for documentation. Reputable brands can provide a current transaction certificate (GOTS) or scope certificate (OEKO-TEX) on request. If a brand cannot produce one, the claim on the label is not substantiated.

In summary

GOTS and OEKO-TEX Standard 100 are complementary, not interchangeable. GOTS tells you something about how the product was made, across the full supply chain. OEKO-TEX Standard 100 tells you something about what the finished product contains when it is tested in a laboratory. A product carrying both has been verified on both dimensions. A product carrying one has been verified on that dimension alone.

If organic fibre content, labour practices, or environmental criteria are part of what you are trying to verify, the certification that covers those is GOTS. If your concern is specifically about residual chemicals in the finished garment, with the strictest thresholds applied to items intended for babies and toddlers, that is what OEKO-TEX Standard 100 Class I is designed for. If both concerns apply, a product carrying both certifications is the most directly verifiable option. Neither standard is a substitute for independent judgement about material, fit, durability, and how a garment is cared for at home.

A note on scope. This article is a reference on what the two standards cover. It is not a substitute for professional advice. For certification-specific questions, consult the issuing bodies directly. For questions about your child's skin, consult a paediatric dermatologist.
