Choosing sustainable fashion often means navigating through various certifications on product labels. Two important terms you might encounter are ISO and GOTS. Understanding their differences and roles can empower you to make informed choices about organic cotton apparel and textiles.
What Is GOTS Certification?
Global Organic Textile Standard (GOTS) is a comprehensive certification tailored specifically for textiles made from organic fibers. It ensures that every step of textile production—from harvesting raw organic cotton to manufacturing, processing, and labeling—complies with high ecological and social standards.
Key Features of GOTS:
- Certified Organic Fiber Content: Products must contain at least 70% certified organic fibers, with a higher label (≥95%) available for “organic” claim.
- Environmental Criteria: Strict limits on chemical inputs (no toxic heavy metals, GMOs, formaldehyde, azo dyes, or PVC), mandatory wastewater treatment, and sustainable packaging requirements.
- Social Criteria: Compliance with International Labour Organisation (ILO) standards, including fair wages, no child or forced labor, safe working conditions, and freedom of association.
- Third-Party Certification: Independent, accredited Certification Bodies conduct annual on-site inspections and audits.
- Traceability: Full chain of custody from farm to final product, ensuring organic integrity is maintained.
- Product Quality: Meets technical standards on colorfastness, shrinkage, and harmful residue limits.
Eco Fact: GOTS covers a wide range of textiles including apparel, home textiles, and personal hygiene products—ensuring environmental and social responsibility at every stage.
What Is ISO and How Does It Relate to Textiles?
The International Organization for Standardization (ISO) develops voluntary international standards applicable across various industries, including textiles. ISO standards provide frameworks for quality, safety, environmental management, and testing methods.
Relevant ISO Standards in Textile and Organic Certification:
- ISO 14024: Defines Type 1 environmental labeling programs, which GOTS certification adheres to for credibility.
- ISO 65: Sets the accreditation requirements for certification bodies that assess compliance with standards like GOTS.
- ISO 5354 (Parts 1 & 2): New standards improving DNA detection in cotton, helping verify organic cotton authenticity and prevent fraud.
ISO standards support the how and by whom testing and certification are conducted but typically do not address the full supply chain ecological and social criteria like GOTS.
ISO vs GOTS: What’s the Difference?
| Aspect | GOTS | ISO |
|---|---|---|
| Scope | Organic textile processing standard | International standards for various processes, management systems, and testing methods |
| Focus | Textile fiber origin, environmental impact, social criteria, product labeling | Quality assurance, environmental management, testing protocols for materials |
| Certification | Third-party certifies entire textile supply chain annually | Sets accreditation criteria for certifiers and testing standards |
| Consumer Relevance | Product label assures organic fiber content, environmental safety, and social responsibility | Certifies quality and safety processes behind the scenes, not always consumer-facing |
| Specificity to Textiles | Fully dedicated to organic textiles, including chemical and social aspects | Broader, applicable to many industries, including textiles |
Why Should Customers Care About These Certifications?
- Experience (Comfort & Durability): GOTS-certified textiles are generally softer, safer on skin, and processed without harsh chemicals, improving comfort.
- Expertise & Authority: GOTS certification involves strict evaluation by internationally accredited bodies following ISO guidelines, ensuring trustworthiness.
- Trust & Transparency: Both standards promote traceability and authenticity—GOTS ensures organic integrity while ISO provides rigorous methods to validate claims.
- Ethical Impact: GOTS requires fair labor conditions and environmental responsibility, empowering consumers to support ethical companies.
How to Check for GOTS Certification?
- Look for the GOTS logo on textile products.
- Verify the certification number, which corresponds to an approved Certification Body.
- Confirm the percentage of organic fibers claimed (≥70% or ≥95%).
- Check that labels specify compliance with environmental and social criteria.
Mini Tip: You can search for certified suppliers or shops in the official GOTS Certified Suppliers Database online.
Takeaway: Making Sustainable Choices with Confidence
Choosing GOTS-certified apparel and textiles means supporting verified organic fiber production and responsible manufacturing practices that protect the environment and workers’ rights. While ISO standards underpin the credibility and technical accuracy of certifications like GOTS, it is GOTS itself that delivers the well-rounded assurance consumers seek for truly sustainable fashion.
By understanding the complementary roles of ISO and GOTS, you can confidently select products that align with your values of quality, safety, and sustainability.
Empower yourself as a conscious consumer: Always look for trusted certifications like GOTS backed by ISO-accredited certifiers when opting for organic cotton and sustainable textiles.
