Data platform availability banner - registered substances
New Data Availability System
A new Data Availability System is being developed by ECHA. To begin with this system will take over the responsibility of making REACH registration data available, once it is ready. We expect the first version to be publicly available by the end of 2023.
Since ECHA aims to devote our maximum effort to this new system, we can no longer maintain REACH registration data on the current Dissemination Platform. As such once the IUCLID format change begins on 19th May 2023 we will no longer update REACH registered substance factsheets. The factsheets will remain online, but will not be updated.
New and updated REACH registration submissions, as well as all registrations on file, will be made available in the new system when it is ready. We will inform you of what you can expect in the new system, along with details of when and where to find it.
We appreciate your understanding in the meantime.

In this table, you will find all public data submitted to ECHA in REACH registration dossiers by substance manufacturers, importers, or their representatives, as laid out by the REACH Regulation (see Understanding REACH regulation).
ECHA makes available this information as REACH registered substance factsheets, which contain the full set of non-confidential information from related registration dossiers for a substance. Depending on the number of registrations that have been made for a substance, one factsheet can thus represent data from anything between hundreds of registration dossiers in a joint submission, to data from just one registration dossier.
As noted in the Legal Notice of the ECHA website, ECHA does not give any guarantees or warranties regarding the quality and correctness of the published information. The information in the portal is published ‘as provided’ by industry, and its accuracy has not been verified by ECHA. ECHA is also not in a position to intervene with, edit or correct the published data; this can only be done by the registrant responsible for its submission. Please also note that the information may be protected and its use may require prior permission from its owner (see the ECHA website Legal Notice more details).
In the portal results table are presented:
- Public substance identity – the best available non-confidential substance name, EC, and CAS numbers.
- Link to the full factsheet.
A subset of the key chemical properties (physico-chemical, environmental fate, ecotoxicological and toxicological data) of registered substances can be searched and accessed via the OECD eChemPortal.
Welcome to the REACH Registered Substance Factsheets
Here you will find details from REACH registrations submitted to ECHA. Registrations under REACH can be submitted either jointly – where a group of legal entities pool their data – or individually. The set of details from each published joint or individual submission is presented as a row in the results table. For each row there is also an ‘eye’ icon leading to the detailed factsheet which contains the entire public dataset, following the IUCLID format.
Note that there can be more than one joint or individual submission for the same substance, thus there can be cases where one substance is covered by many REACH registered substance factsheets.
Note too, that as mentioned in the Legal Notice of the ECHA website, ECHA does not give any guarantees or warranties regarding the quality and correctness of the published information. The information in the portal is published ‘as provided’ by industry, and its accuracy has not been verified by ECHA. ECHA is also not in a position to intervene with, edit or correct the published data; this can only be done by the registrant responsible for its submission.
Finally, please note that the information may be protected and its use may require prior permission from its owner (see the ECHA website Legal Notice more details).
All substances table
The “All substances” table gives an overview of all the REACH registered substance factsheets on file at ECHA. Since this covers all data ever submitted since the entry into force of the REACH Regulation, there are some substances which are no longer considered registered under REACH in the EU / EEA. These can be for example substances that were registered only in the UK; since Brexit they are no longer registered in the EU / EEA.
The following columns are presented in the “All substances” table:
- Public substance identity – the best available non-confidential substance name, EC, and CAS numbers.
- ‘Eye’ icon linking to the full factsheet.
The search for REACH registered substance factsheets is divided into logically separated blocks of related search filters. Note that the search works so that if you provide filters in different blocks, then the results returned must match the filters in block 1 AND those in block 2 etc. Searches are conducted on all the public data included in all published REACH registrations.
In this block you can search by substance identifiers, under filters for Name, EC / List number, and CAS number. Full or partial identifiers can be used. And under the Name filter you can search by any substance name of any kind from any source. Other numerical identifiers such as Harmonised C&L Index number, or PIC CN code can also optionally be used.
In this block you can search by administrative information relating to REACH registered substance factsheets:
- Registration type – picklist of Full, Intermediate, NONS
- Registration status – picklist of Active, Cease Manufacture, No longer valid
- Submission type – Individual or Joint
- Country in which registered – picklist of current and former EU / EEA member states from which REACH registrations were received
- First published date – the date when a REACH registration factsheet was first published
- Last update date – the last date when any registrant / supplier submission contributing to a given REACH registration factsheet was submitted
- Last update year – the year in which any registrant / supplier last made an update submission included in a given REACH registration factsheet
- Registrant / supplier name – where available and not claimed confidential
- Registration number – where available and not claimed confidential
- Registrant address – where available and not claimed confidential
In this block you can search by substance related data from REACH registered substance factsheets:
- Tonnage band – picklist of Tonnage range, Tonnage Confidential, Intermediate use only
- Selected total tonnage band range – available only if Tonnage range is selected, and allows to filter REACH registered substance factsheets within any selected min and max value
- Substance has nanoform – picklist of Yes, No
- PBT assessment outcome – picklist of all possible PBT assessment outcomes
- CSA performed – picklist of Yes, No
Use and exposure
In this block you can search by elements relating to how use and exposure are encoded in REACH registrations.
Under the Life cycle option you can select one or more life cycle stages. The search results returned will include only factsheets containing uses reported under the selected life cycle stages.
Under the Category option there are modal popups for each of the use descriptor categories – Product, Sector of use, Process, Environmental release, and Article categories. In each of these are multi select picklists for all the related descriptor codes. The search results returned will include only factsheets containing uses which include the selected descriptor codes.
Note that the Life cycle and Category options work together, so that if a life cycle stage and Category options are both selected the search results will include factsheets containing specific uses in the selected life cycle stage, and where the use includes the selected descriptor codes.
With the search operator option you can select to refine how the search works. AND refines results and returns only those factsheets where ALL the search filter criteria are met. OR broadens the results and returns factsheets where ANY of the selected search filter criteria are met.
There is always a detailed factsheet per joint or individual submission, and it is generated based primarily on the IUCLID format.
The factsheet header begins with the identity of the substance in question, to which the factsheet is linked. The substance identity should always be aligned with that shown in the related substance Infocard. Note that since the Infocard refreshes daily, whereas the factsheet sometimes refreshes on a slower pace, sometimes the data may be out of alignment. In such cases it will always realign as quickly as possible.
The substance identification is enriched with the data provided in the relevant IUCLID section of the primary submitted dossier – either the joint submission lead, or the single individual submission.
In this section are also provided the type of substance, all other identifiers such as trade names, common names, other names etc, as well as all distinct submitted compositions for the substance.
Next is a page covering administrative type information from the data submitted, including:
Registration details, on the total tonnage band informed to ECHA, the registration type, first published and last updated dates, and whether a chemical safety assessment has been performed.
Registrant / supplier details, giving the identity and status of registrants / suppliers, except where the identity has been claimed confidential.
Registration numbers, giving again the identity and status of registration numbers, except where claimed confidential.
Contact persons responsible for the SDS, giving the non-confidential SDS contacts provided to ECHA.
The remainder of the factsheet faithfully follows the IUCLID structure, covering the C&L and PBT, Manufacture, use, and exposure, Physical and chemical properties, Environmental fate and pathways, Ecotoxicological information, Toxicological information, Analytical methods (if available), Guidance on safe use, Assessment reports, and Reference substances.
