In an increasingly complex textile landscape, certifications and standards provide crucial assurance of fabric quality, safety, and sustainability. Understanding what different certifications mean—and how to verify their authenticity—empowers fashion brands to make informed sourcing decisions, demonstrate credible environmental and social commitments, and meet evolving consumer expectations for transparency and responsibility.
Third-party certifications provide independent verification of claims about fabric properties, production methods, and supply chain practices. In an era when consumers increasingly question greenwashing, certified fabrics help brands substantiate their sustainability communications with credible evidence.
Many markets increasingly require or incentivize certified sustainable products. EU regulations, corporate sustainability disclosure mandates, and government procurement policies often reference specific textile standards, making certification essential for market access.
Certifications impose systematic requirements throughout textile supply chains, helping brands manage quality, identify reliable suppliers, and maintain consistency across complex global networks.
What It Certifies:
GOTS is the leading standard for organic fiber textiles, covering processing, manufacturing, packaging, labeling, trading, and distribution of textiles made from at least 70% certified organic fibers.
Key Requirements:
Why It Matters:
GOTS provides comprehensive assurance that “organic” claims about cotton, wool, silk, or other natural fiber fabrics are legitimate and that textiles are produced with minimal environmental harm and under socially responsible conditions.
Verification:
GOTS certificates include unique transaction certificate numbers that can be verified through the official GOTS database. Certificates should specify the certified facility, scope of certification, and validity period.
What It Certifies:
OEKO-TEX Standard 100 tests textile products for harmful substances at all production stages, from raw materials through finished products. It’s a consumer safety certification rather than a sustainability standard.
Key Requirements:
Why It Matters:
OEKO-TEX Standard 100 assures that fabrics contain no substances hazardous to human health, providing peace of mind for brands concerned about customer safety and potential liability issues.
Verification:
Certified products receive a label number that can be verified through the OEKO-TEX website. Certificates are specific to particular products and must be updated regularly.
What It Certifies:
GRS is an international, voluntary standard that sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices, and chemical restrictions.
Key Requirements:
Why It Matters:
GRS provides credible verification of recycled polyester, recycled cotton, and other recycled fiber content claims. It’s essential for brands marketing products as containing recycled materials.
Verification:
Each GRS transaction certificate includes a unique certificate number verifiable through the Textile Exchange database. Scope certificates should detail what materials and processes are covered.
EcoVero™ by Lenzing:

Cradle to Cradle Certified™:
Assesses products across five categories: material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness.
Even comprehensive certifications have boundaries:
The most sustainable and safely produced fabrics often carry multiple certifications addressing different aspects:
Different certifications emphasize different values:
Some markets prioritize certain certifications:
