Communication from third parties pursuant to Regulation (EC) No 1049/2001 on access to documents

Sometimes applications for access to documents can request the disclosure of third-party documents that European Chemicals Agency (“ECHA”) is in possession. In this event, ECHA has to consult authors or owners of these documents as to whether the disclosure would undermine their commercial interests or intellectual property. This web-form enables the secure exchange of confidential documents to ECHA within this process.
The web-form shall serve as a secure way for third party authors to submit documents as a result of a consultation pursuant to Article 4(4) of Regulation (EC) No 1049/2001. ECHA shall consult the third party authors with a view to assessing whether an exception in Article 4(1) or (2) of Regulation (EC) No 1049/2001 is applicable, unless it is clear that the document shall or shall not be disclosed.
This web-form should only be used by a third-party author after having received a consultation letter from a competent service within ECHA. A specific deadline for the reply will be clearly indicated therein.
Please note that each proposal for non-disclosure should have concrete justifications why the disclosure undermines the protection of your interests pursuant to Article 4(1) or Article 4(2) of Regulation (EC) No 1049/2001. You can send a reply with justifications directly to the competent ECHA service or by using this web-form along with the attachments.
