OCA, GOTS and Textile Exchange expand successful GM cotton testing lab initiative

Global Organic Textile Standard, the Organic Cotton Accelerator (OCA) and Textile Exchange are delighted to announce the renewal of the global ISO IWA 32:2019 proficiency test for a second year in a row, under technical support from Wageningen Food Safety Research.

The initiative aims to provide the sector with an up-to-date overview of global laboratories that can currently conduct GMO testing as per the ISO IWA 32:2019 protocol – a common language among laboratories worldwide to screen for the potential presence of genetically modified (GM) cotton along the organic cotton value chain. 

The joint project involving three global NGOs in the textile sector, announces that it has reached a new milestone with an expanded list of twenty-one laboratories from Europe, Asia and North America who they confirm have successfully passed a new round of the proficiency test in 2021. 

As qualitative GM cotton screening using the ISO IWA 32:2019 protocol is mandatory within the GOTS and OCS (Organic Content Standard) supply chain and OCA’s Farm programme, the expanded list will provide many stakeholders in Organic Cotton with the clarity they need for taking all reasonable precautions to prevent GM cotton in their organic cotton produce while supporting the rapid sector growth seen globally.

The updated overview of the laboratories that successfully passed the proficiency test in 2021 has now been jointly published by GOTS, OCA and Textile Exchange.

Commenting on the second round of the global ISO IWA 32:2019 proficiency test initiative, OCA’s Programme Manager, Mathilde Tournebize, said: 

“At OCA, we believe that by working collaboratively we can make the necessary strides to bring the organic cotton sector improved transparency and integrity, so it is great to see more laboratories implementing the ISO IWA 32:2019 worldwide. This round of proficiency test enabled us to chart additional laboratories that can be contacted to reliably conduct GMO tests as per the ISO IWA 32:2019. The initiative has also expanded to more geographies compared to last year, including Turkey and the United States.“

Rahul Bhajekar, Managing Director at GOTS, added: 

“This initiative shows that through partnership and alignment, we can bring the sector much-needed clarity on qualitative GMO testing in cottonseed, leaf, fibre and chemically unprocessed fibre-derived cotton.” 

Amish Gosai, Supply Network & South Asia Sr. Manager at Textile Exchange, said: 

“The ISO IWA 32:2019 proficiency test initiative will be repeated regularly. More laboratories are welcome to apply for the next round of proficiency test, which will likely be organised in Q1 2023.”



The initiative now in its second year, will drive greater transparency along the organic cotton supply chain in a move that the partners hope will become a fixed bi-annual initiative stemming from the positive feedback from the initial launch in 2020.

Elastic yarns to become more recyclable and environmentally friendly in future

On 29 April 2026, ITA student Tobias Dickmeiß was awarded a sponsorship prize by the Wilhelm Lorch-Stiftung for his innovative approach, to replacing conventional elastane with elastic yarns made from thermoplastic copolyester elastomers (TPC). Thanks to their thermoplastic nature and compatibility with typical polyesters used in the textile industry, elastic TPC yarns offer improved recyclability. Furthermore, the use of the melt-spinning process in yarn production eliminates the need for solvents that are harmful to the environment and human health.
