eChemPortal brings you worldwide information about chemicals in a one-stop source. At a glance, find information on chemicals, pesticides and biocides to support health and environmental decision making. Everything you need to know on chemicals is available through three different searches: substance search, property search and classification and labelling search.

The OECD is pleased to announce the maintenance release of eChemPortal on 16 June 2025. This new version includes an alignment of the chemical property search fields with a newer version of the OECD Harmonised Templates (equivalent to IUCLID 6 v8, released in April 2024).  In addition, fixes and improvements are included, for example for increasing the clarity of the user interface (by grouping property search results by study summary record), and for improving the submission of new information by eChemPortal participating data sources.

The OECD is pleased to announce the maintenance release of eChemPortal on 20 June 2024.

This maintenance release includes an alignment of the chemical property search fields and catalogue with elements of the OECD Harmonised Templates updated in IUCLID 6 v7, which was published in May 2023.  In addition, this new version of eChemPortal provides fixes and improvements, for example for property searches using nested query blocks, and for importing larger datasets.

The Organisation for Economic Co-operation and Development (OECD) is responsible for the development and maintenance of eChemPortal, and eChemPortal is hosted by the European Chemicals Agency (ECHA). The data sources accessed through eChemPortal are maintained by and remain the responsibility of the organisations that create them. The data and information stored in each data source are the responsibility of the data owner. Participating data sources are responsible for ensuring links from eChemPortal to their local data sources are updated.

Holders of Internet-accessible databases or report collections containing peer-reviewed information on physical-chemical properties, environmental fate and pathways, ecotoxicity or toxicity of chemicals, as well as their use and exposure, are invited to participate in eChemPortal.

Proposals should be submitted to the OECD Secretariat at echemportal@oecd.org.
