Dissemination and confidentiality

Can the data disseminated by ECHA be used to prepare SDS?

For downstream users in a supply chain who must generate their own safety data sheets for products procured from within the EEA, the main source of information should be the supplier. Using information from the supplier will ensure that any specific, detailed information is reviewed and included as appropriate.

In addition, use may be made of publicly available information that is not restricted by copyright or any confidentiality protections. It should be noted that, as stated in ECHA's legal notice, reproduction or further distribution of the information from the registration dossiers may be subject to copyright protection and that the use of the information without obtaining the permission from the owner(s) of the respective information might violate the rights of the owner.

Moreover, the legal notice emphasises that the Agency cannot guarantee the correctness of the information in the databases and REACH does not permit the Agency to make modifications to the data provided by the owner(s) of the respective information. ECHA's legal notice can be found under this link: http://echa.europa.eu/en/legal-notice .

It should be noted that the supplier of the Safety Data Sheet is responsible for the accuracy of its contents in all cases.

Where can I see the list of registered substances?

Public access to registered substances is provided on ECHA's website, in  http://echa.europa.eu/information-on-chemicals/registered-substances

The information of the registrant of a particular substance can be found under "Administrative data".

How can I check what information in my registration dossier will be published on the ECHA website before I submit my dossier?

The IUCLID Dissemination preview plug-in simulates which information from a registration dossier will be made public on the ECHA website at: http://echa.europa.eu/information-on-chemicals/registered-substances, according to Article 119 of the REACH Regulation.

To use the tool, right click on your dossier → Dissemination preview → follow the wizard.

Can I hide my identity in the registered substances page on the ECHA website using a third party representative?

No. The identity of the registrant will be published unless a confidentiality claim on the identity of the registrant is included in the registration dossier and the justification accepted as valid by the Agency.

A third party representative (TPR) can be used to represent potential registrants in discussions with other manufacturers, importers and downstream users on data sharing and the joint submission of data as specified in Article 4 of REACH. The identity of the TPR is not published on the ECHA website. It will only be visible in:

  • The pre-SIEF, if included in a pre-registration;
  • the potential registrants tab in the REACH-IT co-registrants page, if included in a successful inquiry notification;
  • the registrants tab in the REACH-IT co-registrants page, if included in a successful registration dossier;
  • and in the joint submission, if included during creation (lead registrant) or confirmation (member registrant) of the joint submission in REACH-IT.
When will my company details be included/updated in the registered substances page after a successful registration?

It takes ECHA up to four weeks from the date of submission to update the information received from registration dossiers.

Once a registration dossier is considered to be complete, the information from your dossier will be filtered for confidentiality, aggregated to merge the information from all dossiers in the joint submission into a single dossier and processed to provide this information in the format of the registered substances page. ECHA regularly updates the information received from registration dossiers. If your registration dossier has gone through all these steps successfully, the information from your registration dossier will be updated in the registered substances page.

You may verify the last updated date at: http://www.echa.europa.eu/information-on-chemicals/registered-substances.

In specific cases where an ‘only representative’ has included the suppliers' identity in section 1.7 of their registration dossier and no confidentiality flags have been added, ECHA understands that the registrant opted for the publication of the supplier's names.

How is the total tonnage band calculated for registered substances published on the ECHA website?

The total tonnage band displayed in the registered substances page is aggregated data calculated from all dossiers in a joint/individual submission. Tonnage data is considered only from full registrations where the tonnage band is not claimed confidential. Tonnage data is extracted from the last year reported in section 3.2 of the IUCLID dossier and is the sum of manufactured + imported tonnage - tonnage directly exported – tonnage immediately used as intermediate.

For dossiers that contain full and intermediate registrations, the tonnage data extracted will be the sum of the reported manufactured plus imported tonnage fields, minus the tonnage immediately used as intermediates. Tonnage data will be summed for all dossiers in a joint/individual submission, and will be displayed as:

  • A tonnage band range, i.e., 100 000 – 1 000 000 tonnes, if no dossier contains a confidentiality claim on tonnage band;
  • Open tonnage band, i.e., 1 000+ tonnes, when at least one dossier contains a confidentiality claim on tonnage band;
  • "Tonnage data confidential", when all dossiers aggregated have claimed their tonnage band as confidential, REACH Articles 119(2)(b); and
  • "Intermediate use only", when only intermediate registration dossiers are present in the joint submission.
What information in a NONS dossier can be claimed confidential under REACH?
Additional information can be claimed confidential under REACH which was not possible to claim under NONS:
- The name of the notifier (which under REACH is considered to be part of the information contained in the safety data sheet)
- The information contained in the safety data sheet (including registration number, uses and uses advised against).
- The trade name of the substance.
- If essential to classification and labelling, the degree of purity of the substance and the identity of impurities and/or additives which are known to be dangerous.
ECHA will give the same possibilities for claiming confidentiality to NONS notifiers as to other REACH registrants. Therefore, should your company consider that this information should not be published on the ECHA website, despite the non-confidential character of this information in the past, you can introduce the relevant confidentiality claims. These confidentiality claims need to be properly justified and the fee for claiming this information confidential in accordance with article 119(2) will be charged. The Question and Answers on NONS have further details (including for unclaimed NONS) and can be found here.
Why doesn’t the registered substance page contain information on products in buy?

REACH applies to chemical substances and therefore the registered substance page contains information only about chemical substances. It does not contain information about chemical preparations, formed by mixing together several chemical substances, nor about articles containing chemicals. In other words, you can find information about methanol or butane, but not for example about a shampoo, cleaning products or pencils.

Why can’t I find the substance I am looking for?

If the substance you are looking for has not been registered, it is not available in the database. Substances will be included in the database within 4 – 8 weeks after the European Chemicals Agency has received a registration dossier for this substance.

REACH has three deadlines for registering substances. They are 30 November 2010, 31 May 2013 and 31 May 2018. The deadline depends on the tonnage band and the hazardous properties of the substance. About 30,000 substances are expected to be available in the database after expiry of the last registration deadline in 2018.

Can I trust the data provided in the registered substance page?

The information originates from registration dossiers submitted by companies. Companies have the obligation to provide accurate and up-to-date information in their registration dossiers. ECHA's IT systems verify that the information is complete, meaning that all the information fields required for a registration in a particular tonnage band are filled in in the dossier. However, the European Chemicals Agency (ECHA) does not verify the information before its publication on the internet. ECHA can therefore not guarantee the correctness or adequacy of the information or that the dossiers are compliant with REACH.

Where can I send questions regarding the registered substance page?
If you are a registrant, and you have questions about dissemination, please contact the ECHA helpdesk.
If you are a journalist, please contact the ECHA Press Office (press (at) echa.europa.eu).
For any other questions contact the ECHA Information Desk

To leave feedback, please use the feedback form on the portal.

In the case of an only representative, what name will appear on the dissemination page: the non-EU company or the only representative?

The table below defines which legal entity will be disseminated on ECHA’s webpage depending on information provided in sections 1.1 and 1.7 of your IUCLID dossier.
