Alignment with IMDS

The International Material Data System (IMDS) updated its database on March 14, 2025, to reflect these GADSL changes, ensuring alignment with industry reporting standards. Automotive companies must review the updates and adjust their Material Data Sheets (MDS) to stay compliant and meet customer requirements.

Compliance Guidelines

To ensure compliance with the updated GADSL, automotive companies should take the following steps:

1. Assess Impact on Existing Products: Review materials and products to identify substances now classified as declarable or prohibited.
2. Update Material Data Sheets (MDS): Ensure accurate reporting of all substances and avoid hiding GADSL-listed substances under wildcard entries.
3. Communicate with Suppliers: Inform suppliers about the updates and request revised MDSs for the components they supply.
4. Implement Compliance Checks: Regularly verify that materials and components conform to the latest GADSL standards.

By staying informed and proactive, the automotive industry can continue to meet safety, environmental, and regulatory requirements.
