Universe of registered substances
Universe of registered substances
ECHA has created a mapping tool of all registered substances called the chemical universe in which each substance is assigned to a pool that indicates the regulatory actions already initiated or under consideration for that substance. It also identifies those substances for which the need for suitable regulatory actions still needs to be determined.
The chemical universe helps national authorities, ECHA and the European Commission focus on substances of (potential) concern and identify appropriate regulatory actions. This is key for authorities to achieve the REACH objectives increasing the protection of human health and the environment. ECHA publishes the chemical universe to improve transparency on the actions of authorities towards industry and other stakeholders.
For all substances registered above one tonne per year, ECHA’s goal is to conclude by the end of 2027 whether they are:
- a priority for regulatory risk management;
- currently a low priority for further regulatory action; or
- a priority for data generation.
Figure: REACH chemical universe: substances with active registrations above 1 tonne/year.
> 100 tonnes: Substances for which there is at least one active registration under Article 10 of REACH registering at a tonnage above 100 tonnes per year.
1 - 100 tonnes: Substances for which there is at least one active registration under Article 10 of REACH registering at a tonnage between 1 and 100 tonnes per year, and for which there are no active registrations registering at a tonnage above 100 tonnes per year under Article 10 of REACH.

* substances only covered by unclaimed NONS are not anymore considered registered and therefore not reported in the Chemical Universe. See https://echa.europa.eu/-/window-to-claim-registration-numbers-for-nons-now-closed
The chemical universe is based on a snapshot of ECHA’s database from December 2022. The pool assignment may have changed for some substances since then, for example, due to started or completed regulatory actions. Check the latest information in each substance’s infocard.
More information about the pools is available on the web page: How does the chemical universe mapping work?
You can download a list of all REACH registered substances by accepting the disclaimer and clicking on the link below. The list indicates which pool the substances were assigned to and contains a direct link to the infocard of each substance.
Disclaimer: The assignment of individual substances to the regulatory pools is based on the currently available information on past, ongoing or planned regulatory actions. The assignment to pools is automatically generated. Despite ECHA’s best efforts to avoid mistakes, the Chemical Universe is not necessarily comprehensive, complete, accurate, or up to date. ECHA provides the chemical universe mapping for information only. The publication of the chemical universe does not relate to any regulatory procedure set out by REACH. More specifically, it is not a condition set out for the compliance check of dossiers or the adoption of risk management measures. Similarly, the information published on the chemical universe must not be relied upon to conclude whether a substance is hazardous or can be used safely. Authorities retain the right to initiate any regulatory action on a substance regardless of what is indicated in the chemical universe.
