OEKO-TEX is a partnership of 18 separate research and testing institutions specializing in textiles and leather. Its base certification, STANDARD 100, includes strict chemical compliance standards and ensures that all final product components are completely free from substances harmful to humans. STANDARD 100 draws on a precautionary principle, meaning that its limits can be stricter than the values required by national and international legislation. The criteria for certification are updated annually to reflect new knowledge or legal requirements.(1) MADE IN GREEN (MiG) is a traceable product label that builds on the STANDARD 100, with additional environmental and social criteria that focus on 6 key areas: chemicals management; environmental performance; environmental management; social responsibility; quality management; and health protection and safety at work. These must be met across all stages of the supply chain, including textile production, spinning, weaving and knitting mills, finishing facilities and garment manufacturers.(2)
