Change Announcement Regarding ISO/DIS 5354-1.2, ISO/TS 5354-2 and IWA 32:2019
There has been a change in the test method applied for the presence of Genetic Modification in cotton.
ISO has publicly announced that it has revoked the approved test method ISO IWA 32:2019 for the analysis of GOTS Products and has instead published the standards under the number ISO/DIS 5354-1.2 (parts 1 and 2).
* ISO/DIS 5354-1.2 : Molecular biomarkers — Detection of DNA in cotton used for textile production — Part 1: Extraction of DNA from cotton seed and raw materials derived therefrom.
* ISO/TS 5354-2 : Molecular biomarkers — Detection of DNA in cotton used for textile production — Part 2: Overview of target sequences for use in polymerase chain reaction (PCR)-based detection methods for cotton genetically modified (GM) events
Laboratories will need time to transition to the new method, so although tests are expected to be carried out in the last quarter of 2025 or early 2026 according to ISO 5354, we recommend that you follow official notifications on the subject. Until then, ISO IWA 32 tests will be allowed.
"With the above-mentioned current ISO Standards "ISO/DIS 5354-1.2" and "ISO/TS 5354-2" becoming mandatory, please ensure that you use the laboratory accredited according to these standards instead of ISO IWA 32 to perform the relevant analyses."
