OEKO-TEX vs GOTS: What These Textile Standards Actually Mean
When brands like Allwear reference OEKO-TEX or GOTS standards, what exactly does that mean? These are two of the most important textile certifications in the world, but they cover different things. This guide explains both standards in plain language, what they test for, and what it means for your clothing purchases.
Side-by-Side Comparison
| Aspect | OEKO-TEX | GOTS |
|---|---|---|
| Full Name | OEKO-TEX Standard 100 | Global Organic Textile Standard |
| Focus | Chemical safety of finished textiles | Organic fiber production + processing |
| Tests For | Harmful substances in the final product | Organic content + environmental/social criteria |
| Fiber Requirement | Any fiber (including synthetic) | Minimum 70% organic natural fibers |
| Environmental Scope | Product safety only | Full supply chain sustainability |
| Social Criteria | Not included | Fair labor and working conditions required |
| Logo on Product | "Confidence in Textiles" label | GOTS certified organic label |
What Is OEKO-TEX Standard 100?
OEKO-TEX Standard 100 is a product safety certification that tests the finished textile product for harmful substances. It was established in 1992 and is one of the world's most widely recognized textile testing systems.
The certification tests for over 100 individual substances, including formaldehyde, heavy metals, pesticides, chlorinated phenols, phthalates, and certain dyes. Products are tested at independent laboratories, and the limits are often stricter than national and international regulations.
Important note: OEKO-TEX tests the final product, not the production process. A polyester garment can be OEKO-TEX certified if the finished product is free from harmful substances, even though polyester production itself has environmental concerns.
What Is GOTS?
The Global Organic Textile Standard (GOTS) is a more comprehensive certification that covers the entire textile supply chain, from harvesting raw organic fibers through manufacturing, labeling, and trading. GOTS was developed by a group of international organizations and is considered the leading standard for organic textiles.
To carry the GOTS “organic” label, a product must contain at least 95% certified organic fibers. The “made with organic” label requires at least 70%. Beyond fiber content, GOTS also mandates environmental criteria for processing (water treatment, energy use, chemical restrictions) and social criteria (fair wages, safe working conditions).
Which Matters More for Your Health?
For personal health and chemical safety, both are valuable but in different ways. OEKO-TEX directly tests the product you'll be wearing for harmful substances, making it the most relevant for immediate skin safety. GOTS ensures the organic integrity and clean processing of the entire product, which provides broader assurance.
The ideal scenario is clothing that meets both standards, which means organic fiber content that has been processed without harmful chemicals and verified in the final product. When brands reference both standards, as Allwear does, it indicates a commitment to both organic sourcing and product safety.
A Note on “Referencing” vs “Certified”
It's important to distinguish between a brand being “certified” (holding a valid certificate number that can be verified on the OEKO-TEX or GOTS databases) and “referencing” these standards (stating that their materials are sourced from certified suppliers).
Many brands source from OEKO-TEX or GOTS certified suppliers without holding the certification directly. This is common and legitimate, but consumers should be aware of the distinction. If certification is important to you, look for specific certificate numbers on product pages.
