GOTS vs OEKO-TEX: Which Certification Should You Look for in Knitwear?
For brands committed to a more ethical supply chain, certifications are the key to building consumer trust. So, which should you look for in knitwear: GOTS or OEKO-TEX? It’s a common question, and the answer depends on your core values. While both labels signal a commitment to sustainability, their focus is fundamentally different. GOTS is a holistic certification that covers the entire supply chain, whereas OEKO-TEX is focused solely on ensuring the final garment is free from harmful chemicals.
What Are the Global Organic Textile Standard (GOTS) and OEKO-TEX?
Understanding the core purpose of each certification is the first step in deciding which is right for your brand. While both are globally recognized, they certify different aspects of a product's life cycle.
What is GOTS?
The Global Organic Textile Standard (GOTS) is the gold standard for sustainable knitwear and textiles because it’s a holistic, end-to-end certification. GOTS verifies the entire journey of the material, from the organic farm that grows the raw fiber to the final factory that knits the garment. It’s a comprehensive system that takes into account both environmental and social responsibility.
Key aspects certified by GOTS:
Organic Fibers: The material must be at least 70% certified organic fiber.
Eco-Friendly Production: It restricts the use of harmful chemicals, dyes, and finishes throughout the entire production process. It also requires manufacturers to have effective wastewater treatment and environmental management systems.
Ethical Labor: GOTS enforces social criteria based on the International Labour Organization (ILO) conventions, ensuring workers are paid fairly, have safe working conditions, and are not subject to forced or child labor.
Full Traceability: The standard requires every single step of the supply chain to be independently audited and certified, providing complete traceability and transparency from farm to final product.
What is OEKO-TEX?
OEKO-TEX is a more focused, product-based certification system that tests textiles for harmful substances. It is a globally recognized mark of safety, giving consumers the confidence that the products they purchase are not a health risk. It does not, however, address the environmental impact of the manufacturing process or the ethical treatment of workers.
The most common OEKO-TEX label is the OEKO-TEX® STANDARD 100, which certifies the final product is free from over 350 harmful chemicals, including pesticides, heavy metals, and allergenic dyes. Other labels, such as STeP by OEKO-TEX, focus on sustainable production facilities, but the primary OEKO-TEX standard is a chemical safety test.
Which Certification is Better for My Brand and Supply Chain?
The answer depends entirely on your brand's core values and what you want to communicate to your customers. Many brands choose to get both certifications, using GOTS to verify their ethical and organic supply chain and OEKO-TEX to provide a final safety guarantee for the customer.
Here is a quick comparison to help you decide:
Feature | GOTS (Global Organic Textile Standard) | OEKO-TEX® STANDARD 100 |
Scope | Entire supply chain (farm to finished product) | Finished product only |
Focus | Organic content, social compliance, & environmental impact | Human-ecological safety (free from harmful substances) |
Social Criteria | Yes. Enforces fair labor standards (ILO) | No. Does not cover social or ethical practices |
Chemicals | Bans hazardous substances from production | Tests for over 350 harmful substances in the final garment |
Organic Content | Requires at least 70% certified organic fiber | No organic content requirement |
What are the Benefits of a Dual-Certified Supply Chain?
In today's competitive market, trust is a brand's most valuable asset. A dual-certified supply chain—one that uses GOTS and OEKO-TEX—offers a compelling narrative of both ethical production and product safety.
Builds Consumer Trust: By having both certifications, you can confidently tell your customers that your product is not only made with sustainable, ethically-sourced materials but is also free of harmful chemicals.
Market Access: Retail buyers and B2B clients in the UK and US increasingly require third-party certifications as a non-negotiable part of their sourcing process.
Competitive Advantage: Less than 1% of the world's cotton is certified as organic. By embracing certifications like GOTS, you position your brand as a leader in a crowded market.
FAQs: Your Questions Answered
Q. Is it possible for a product to be both GOTS and OEKO-TEX certified?
Yes. A product can be made with GOTS-certified organic cotton, ensuring ethical and environmental standards throughout the supply chain, and then be additionally tested and certified under the OEKO-TEX STANDARD 100 to ensure it is free from harmful chemicals.
Q. Does an OEKO-TEX label mean my product is sustainable?
No. While it's an important step for product safety, an OEKO-TEX certification does not mean the material is organic or that it was produced with ethical labor. It only guarantees the final product is free from harmful substances.
Q. How do I verify a manufacturer's certification?
You can verify both GOTS and OEKO-TEX certifications online. Both organizations maintain public databases where you can search for a manufacturer's certificate number to confirm its validity and scope.
Q. Are certifications a good investment for a new brand?
Absolutely. While there is a cost associated with certifications, it is a crucial investment in building long-term consumer trust and can open doors to new markets and retail partners.
