The latest revisions to the Global Automotive Declarable Substance List (GADSL) will be officially implemented in the International Material Data System (IMDS) on March 20, 2026.

This update ensures that newly identified declarable and restricted substances are digitally integrated into IMDS, enabling real-time compliance tracking across the global automotive supply chain.

Latest Updates in the GADSL

1. Addition of New Declarable Substances

The updated GADSL introduces newly classified substances that:

  • Require mandatory declaration once threshold limits are exceeded

    • May be restricted or prohibited under global regulations

    Are linked to evolving concerns such as toxicity, persistence (e.g., PFAS), and recyclability impacts

2. Automatic Flagging in IMDS

Once implemented:

  • IMDS will automatically flag materials containing updated GADSL substances
  • Flags will appear at component and material levels within submissions
  • Suppliers and OEMs will receive compliance alerts during data entry and validation
  • This significantly reduces the risk of non-compliant submissions and improves early detection.

3. Alignment with Global Regulations

The GADSL update reflects regulatory developments across major jurisdictions, including:

  • REACH Regulation (EU)
  • ELV Directive (EU)
  • Emerging restrictions on PFAS, heavy metals, and flame retardants
  • This ensures IMDS remains aligned with global compliance expectations.

Industry Impact

The integration of updated GADSL substances into IMDS reinforces the automotive sector’s commitment to:

  • Chemical transparency across the supply chain
  • Regulatory compliance and risk mitigation
  • Sustainable material selection and recyclability

However, it also increases operational pressure on:

  • Tier-1, Tier-2, and raw material suppliers
  • OEM compliance and sustainability teams
  • Companies must now ensure higher accuracy, traceability, and responsiveness in material declarations.

Key Compliance Risks

Failure to align with updated GADSL requirements may lead to:

  • Rejection of IMDS submissions by OEMs
  • Delays in product approvals and SOP timelines
  • Non-compliance with global chemical regulations
  • Increased audit and reporting risks

What Companies Need to Do ?

With the update going live, companies should take immediate and structured actions:

    1. Review Existing IMDS Data

    • Identify materials containing newly flagged substances
    • Revalidate legacy submissions for ongoing programs

      • 2. Update Material Declarations

    • Revise Material Data Sheets (MDS) in IMDS
    • Ensure correct classification (declarable, prohibited, exempted)

      • 3. Engage Supply Chain

    • Communicate updates to suppliers and sub-suppliers
    • Request updated declarations and full material disclosures (FMDs)

      • 4. Strengthen Internal Controls

    • Update compliance checklists and validation rules
    • Train teams on new GADSL substance categories

      • 5. Monitor Official Notifications

    • Track updates from IMDS releases and GADSL publications
    • Review internal alerts (including automated IMDS notifications and emails)

    What’s New in This Update

    • Real-time system-level enforcement via IMDS flags
    • Inclusion of emerging high-risk substances (e.g., PFAS-related groups)
    • Greater emphasis on data quality and supply chain transparency
    • Closer linkage between regulatory compliance and digital reporting systems

    Strategic Significance

    This update marks a shift toward digital compliance enforcement, where:

    • Regulatory requirements are embedded directly into reporting tools
    • Compliance becomes proactive rather than reactive
    • Data transparency supports circular economy and recyclability goals
