GRS + OEKO-TEX® Together Deliver Maximum Brand Trust
For synthetic activewear made from recycled nylon or polyester, combining GRS (Global Recycled Standard) and OEKO-TEX® STANDARD 100 certification delivers the strongest brand trust. GRS verifies recycled content claims and supply chain traceability, while OEKO-TEX® independently tests for harmful substances—together they address both sustainability and consumer safety in one garment.
What Each Certification Brings
GRS Certification
Verifies recycled content claims, requires chain-of-custody traceability, and enforces environmental and social criteria throughout the supply chain. Best for proving your products genuinely contain recycled materials.
OEKO-TEX® STANDARD 100
Tests every component for harmful substances through independent laboratory analysis. The most recognized consumer safety label for textiles, giving customers confidence that your activewear is free from chemicals of concern.
Which Scenario Fits Your Brand?
| Your Focus | Best Certification | Why |
|---|---|---|
| Recycled synthetic activewear | GRS + OEKO-TEX® | Covers both sustainability claims and safety testing |
| Organic cotton activewear | GOTS | Comprehensive organic standard from field to finished garment |
| Recycled content claims only | RCS or GRS | Content verification without broader social/environmental criteria (RCS) or with them (GRS) |
| Safety assurance only | OEKO-TEX® | Independent lab testing for harmful substances |
Key insight: Major retailers increasingly expect dual certification. A GRS + OEKO-TEX® label tells a retailer you have met both recycled-content traceability and consumer safety standards in one product, reducing compliance friction significantly.
Making the Choice
- If you sell synthetic activewear and want maximum credibility—choose both GRS + OEKO-TEX®.
- If you start with one, begin with OEKO-TEX® for broad consumer safety appeal, then add GRS as recycled-content claims become important.
- For organic cotton collections, GOTS alone is sufficient and widely recognized.
