GOTS Certification: What It Covers & Doesn't

GOTS Certification: A Technical Examination of Its Scope

The Global Organic Textile Standard (GOTS) is a voluntary global standard for the post-harvest processing of textiles—including spinning, knitting, weaving, dyeing, and manufacturing—from certified organic raw materials. It primarily ensures the organic status of textiles by defining strict environmental and social criteria throughout the entire textile supply chain. Established in 2006, GOTS was created to harmonize the various existing standards and certifications in the field of organic textiles, providing a unified and internationally recognized benchmark for the industry. However, it is crucial to understand that GOTS does not certify the organic farming stage itself; the raw natural fibres must be certified as organic by a recognized international or national standard, such as the USDA National Organic Program (NOP) or the EU Organic Regulation. This distinction is fundamental to understanding the scope and application of the GOTS certification.

Defining the GOTS Framework: Two Label Grades

GOTS certification is structured around two distinct label grades, which are determined by the percentage of certified organic fibre in the final product. The first, 'organic', requires that a minimum of 95% of the fibres used are certified organic. The remaining 5% can be composed of non-organic natural or synthetic fibres, though certain materials like conventional cotton, angora wool, and virgin polyester are explicitly prohibited. This small allowance for non-organic fibres is intended to accommodate certain functional requirements, such as elasticity or durability, that may not be achievable with 100% organic materials. The second label grade, 'made with organic', requires a minimum of 70% certified organic fibres. For this grade, the remaining 30% of the material composition has stricter limitations; for example, a maximum of 10% can be synthetic fibres (or 25% for socks, leggings, and sportswear), and the use of recycled synthetic fibres is permitted. These two grades provide a clear and verifiable framework for consumers and manufacturers to understand the organic content of a product. The standard also mandates that the percentage of organic fibre is clearly stated on the label, ensuring transparency for the end consumer. This dual-label system allows for flexibility in product development while maintaining a high level of organic integrity. The scope of GOTS covers a wide range of products, including yarns, fabrics, clothing, home textiles, and personal care products containing textile components.

Environmental Criteria: From Chemical Inputs to Wastewater

The environmental criteria of GOTS are among the most stringent in the textile industry. The standard prohibits the use of a wide range of chemicals known to be harmful to human health and the environment. This includes toxic heavy metals (such as lead, cadmium, and mercury), formaldehyde, aromatic solvents, functional nanoparticles, and genetically modified organisms (GMOs). All colorants and chemical auxiliaries must be evaluated against the standard's rigorous requirements and be approved by a GOTS-accredited body before they can be used. This 'approved positive list' of substances is a core component of the GOTS system, ensuring that only the safest possible inputs are used. The standard also prohibits the use of azo dyes that release carcinogenic arylamines. Furthermore, all wet-processing facilities must have a functional wastewater treatment plant to treat all effluent. Key parameters such as pH, temperature, Chemical Oxygen Demand (COD), and Biological Oxygen Demand (BOD) must be monitored to ensure the discharged water does not harm the surrounding ecosystem. The limits for these parameters are based on the best available technology and are regularly reviewed and updated. Certified entities are also required to have a written environmental policy and maintain detailed records of their energy and water consumption, with a stated goal of minimizing their environmental footprint. This includes setting targets for reduction and demonstrating continuous improvement in resource efficiency. GOTS also sets requirements for packaging, prohibiting the use of PVC and requiring that all paper and cardboard used is recycled or certified by a sustainable forest management program like FSC or PEFC.

Social Compliance: The ILO Core Conventions

A key component of the GOTS standard is its comprehensive social criteria, which are based on the core conventions of the International Labour Organization (ILO). These criteria apply to all processing and manufacturing stages and are designed to protect the rights of workers throughout the supply chain. The standard explicitly prohibits forced or bonded labour, child labour, and any form of harsh or inhumane treatment. It mandates that working conditions must be safe and hygienic, and that workers have the right to freedom of association and collective bargaining. This includes the right to form and join trade unions and to bargain collectively without fear of reprisal. Furthermore, GOTS requires that wages paid to workers must meet, at a minimum, national legal standards or industry benchmarks, and should be sufficient to meet basic needs and provide some discretionary income—a concept often referred to as a 'living wage'. The standard provides a methodology for calculating a living wage, which takes into account the local cost of living. Working hours must not be excessive and must comply with national laws and benchmark standards, including provisions for overtime and rest days. These social compliance requirements are verified through on-site inspections by independent, third-party certification bodies, which include confidential worker interviews and a review of all relevant documentation. The social criteria also include provisions for non-discrimination and the protection of marginalized groups.

What GOTS Certification Does Not Cover

While GOTS is a comprehensive standard, it is important to understand its limitations. As previously mentioned, GOTS does not certify the organic farms themselves; it relies on IFOAM-accredited certifications for the raw organic fibre. This is a critical distinction, as the scope of GOTS begins at the post-harvest stage. The standard also does not set specific requirements for the durability, performance, or quality of a textile product. A GOTS-certified garment is not inherently more durable than a non-certified one; its certification is a guarantee of its organic and responsible production, not its longevity. While the use of high-quality organic fibres and the prohibition of certain harsh chemical treatments can contribute to a product's longevity, this is not a direct focus of the standard. Additionally, the standard does not cover the 'use' phase of a product's life cycle (such as the environmental impact of laundering) or its end-of-life (such as recycling or disposal), although the restrictions on harmful chemicals do facilitate safer disposal and circularity. Finally, GOTS does not cover a company's overall business ethics, pricing policies, or design processes that fall outside the direct manufacturing chain. It is a product certification, not a certification of a company's overall sustainability performance. For a more holistic assessment of a brand's sustainability, consumers may need to look for additional certifications or reports, such as B Corp certification or a company's own sustainability report.

Frequently Asked Questions

Is GOTS the same as 'organic'?

No, GOTS is a processing standard, not a farming standard. A product labeled 'organic' without the GOTS logo may refer only to the raw fibre, without any guarantee about the processing, dyeing, or manufacturing stages. GOTS certification provides a verifiable assurance that the entire supply chain, from the first processing step to the final product, adheres to strict organic and ethical criteria.

Does GOTS certification mean a product is 100% organic?

Not necessarily. GOTS has two label grades: 'organic' (minimum 95% organic fibres) and 'made with organic' (minimum 70% organic fibres). The exact composition will be stated on the product's label. It is important to check the label for the specific percentage of organic content. For more information on our commitment to sustainable materials, please visit our materials page.

Does GOTS certify animal welfare?

While GOTS is not an animal welfare standard, it does require that any animal fibres used in GOTS-certified products are sourced from farms that adhere to recognized organic farming standards, which include provisions for animal welfare. For example, mulesing of sheep is strictly prohibited. However, for more comprehensive animal welfare assurances, consumers should look for additional certifications such as the Responsible Wool Standard (RWS) or the Responsible Down Standard (RDS).
