It includes all operationally relevant areas (management, production technologies, resource uses, quality assurance, safety precautions, social conditions etc.) in its sustainability review. To be certified as complying with the Standard Oeko-Tex®, companies must meet criteria relating to their environmentally-friendly production process, as well as being socially acceptable at all stages of production. |

| FAIR MADE | The Fair Trade Certified™™ is the first step towards fairer pay for those in the supply chain. Since they do not own any of the factories that manufacture their products, they have limited control over workers' salaries. But thanks to the Fair Trade program, they can supplement workers' wages with benefits that improve their quality of life. |
