Welcome to the Global Automotive Declarable Substance List. The GADSL is free for non-commercial use. As of October 29, 2025, a data licensing agreement for commercial use is available by purchase by contacting info@gadsl.org.
The GADSL is the result of the efforts of a global team from the automotive, automotive parts supplier (tier supplier) and chemical/plastics industries who have organized the Global Automotive Stakeholders Group (GASG). The GASG’s purpose is to facilitate communication and exchange of information regarding the use of certain substances in automotive products throughout the supply chain. The GADSL only covers substances that are expected to be present in a material or part that remains in a vehicle at point of sale.
Many individual declarable substance lists were developed to exchange information regarding the material and substance composition of automotive parts. The experience gained by the automotive, automotive parts supplier (tier supplier) and chemical/plastics industries in using these multiple lists has shown that the declaration process could be improved upon and this was a key reason for developing a single, globally harmonized list with clear criteria and a transparent process to manage future versions of the GADSL.
Two downloadable documents are available after filling out the registration form, the GADSL Guidance Document (PDF) and the GADSL Reference List (Excel). The GADSL Guidance Document is the master document that lists individual declarable substances, substance groups (families) and describes how the GADSL should be used. The Reference file provides CAS numbers for individual substances of a chemical group or family (e.g. lead and its compounds) appearing on the GADSL, should they be needed. Registration remains valid for 2 years after which a person must complete the registration form again to continue to access the GADSL Guidance Document and Reference List.

PLEASE NOTE: Not all substances on the GADSL are prohibited from automotive use. Substances listed are or could be potentially regulated but are not necessarily candidates for substitution. GADSL is intended to communicate the use of these substances in the automotive industry to support government regulations and requests as well as providing guidance on substance restrictions. Please do not refer to GADSL as a “blacklist” or a “ban list.”
CRITICAL RAW MATERIALS: The following link is provided for information relative to reporting of substances identified as European Critical Raw Materials: IMDS-GADSL-CRM. Parts containing these substances should be reported in IMDS. IMDS data containing these Critical Raw Materials starts to be populated in 2021, with mandatory reporting commencing in 2022.
