OEKO-TEX® and ZDHC collaborate closely to harmonize requirements. ECO PASSPORT certificates adhere to the latest ZDHC MRSL and Conformance Guidance. Furthermore, ECO PASSPORT certificates marked as ZDHC MRSL 3.0 compliant also comply with ZDHC MRSL 3.1. OEKO-TEX® fully supports the ZDHC initiative, ensuring compliance through various services. The STeP MRSL encompasses all chemicals banned by the latest ZDHC MRSL, and the OEKO-TEX® STeP chemical list covers all substances required by the ZDHC wastewater guideline. OEKO-TEX® recognizes the ZDHC list of provisionally accepted laboratories for wastewater testing as a reference (visit ZDHC website).
