TESTEX, an independent Swiss testing and certification organization operating worldwide with the focus on textile testing, and China Textile and Apparel recently held a webinar theming “OEKO-TEX The Present & The Future: From product safety to the sustainable development, the journey we have been going through together for decades.”

TESTEX headquartered in Zurich and has twelve other branch offices. The guest speakers from TESTEX for the webinar included Coline Leung, Deputy Marketing Manager; Catherin Hon, Customer Service - Senior Executive; and Anson Ho, Customer Service - Executive.

During the webinar, Coline Leung introduced the latest updates and development of OEKO-TEX certifications. OEKO-TEX consists of 18 independent institutes worldwide and works to develop test methods and limit values for the textile and leather industries.

OEKO-TEX certifications include STANDARD 100 by OEKO-TEX, MADE IN GREEN by OEKO-TEX, STeP by OEKO-TEX, and more.

TESTEX is a member of the OEKO-TEX, conducting textile-related physical and chemical tests with the aim to ensure product safety, sustainability and responsibility along the global textile value chain.

“STeP by OEKO-TEX is the most comprehensive certification among our portfolio because it covers assessment of sustainability under six modules. They are chemicals management, environmental performance, environmental management, social responsibility, quality management, and occupational health and safety,” said Coline Leung.

She added that the details of STANDARD 100 by OEKO-TEX, LEATHER STANDARD by OEKO-TEX, STeP by OEKO-TEX, MADE IN GREEN by OEKO-TEX, and ECO PASSPORT by OEKO-TEX have been modified and updated in April this year.

For example, for MADE IN GREEN category, in order to ensure the supply chain transparency for buyers and consumers, production facilities should add at least three components for finished products or one component for semi-finished products, according to OEKO-TEX.

Recycled materials certified separately with hangtags

On the other hand, Anson Ho talked about the certification of recycled materials with STANDARD 100 by OEKO-TEX. The demands for recycled materials for textile and fashion products have been increasing significantly. As a result of the challenges posed to certify recycled materials with complex origins, OEKO-TEX has integrated recycled materials into the STANDARD 100 by OEKO-TEX, by increasing testing frequencies and improving the reporting process.

In other words, recycled materials are also certified within the STANDARD 100 by OEKO-TEX framework like regular virgin materials, though these recycled materials are treated differently.

Applicants can still choose to certify the articles produced by recycled materials in any of the four product classes listed by STANDARD 100 by OEKO-TEX. However, different rules may apply. For example, except PET bottle, articles produced by post-consumer materials can only be certified in product classes II-IV.

“Recycled materials are handled differently and certified separately as a special category, and an OEKO-TEX hangtag to signify the use of recycled materials has been added for B2C marketing to raise awareness for environmental protection,” Anson Ho remarked.


In the Q&A session, some of the audience would like to know how to obtain MADE IN GREEN by OEKO-TEX certification. “All players of the textile supply chains can get the MADE IN GREEN certification when they manage to comply with certain criteria,” explained Catherine Hon.

According to TESTEX, the criteria include “made with materials tested for harmful substances”, “made in environmentally friendly facilities” and “made in safe and socially responsible workplaces”.
