Submitting downstream user notification of authorised uses

If you are a downstream user of a substance listed on the Authorisation List (Annex XIV) and are using it under an authorisation granted to a supplier further up your supply chain, you must notify ECHA of your use. Additionally, when using the substance, you must adhere to the conditions of the authorisation, which your supplier is required to outline in the safety data sheet. 

To verify whether your use of an Annex XIV substance is authorized, follow these steps: 

  1. Check the Safety Data Sheet (SDS): The authorisation number is provided in the SDS that your supplier gives you. 
  1. Examine the Label: The authorisation number is also displayed on the substance or mixture label. It follows the format “REACH/x/x/x”. 
  1. Contact your Supplier: If you cannot find the authorisation number in either place, reach out to your supplier for confirmation. 

You must notify ECHA within three months of the first delivery of the substance. This obligation starts after the authorisation decision is published in the Official Journal. 

You need to submit the following information: 

  • Your company’s identity 
  • The authorization number 
  • Contact information 

You may also provide details about the typical annual volume and the number of staff using the substance. Additionally, you can include a brief description of your use and any involvement in potential substitution activities. 

If the authorisation decision requires specific data, such as exposure information, you must attach a file to your notification by the deadline set in the decision. 

Create Your Notification Dossier in IUCLID 

Create an IUCLID dossier to notify your use to ECHA. You can do this on your local computer or use IUCLID on ECHA Cloud Services. IUCLID 6 on our Cloud Services is free and always up to date. 

Submit Your Notification 

You need an active REACH-IT account to submit your notification. Links to REACH-IT are on the right-hand side of this page. 

Sign up in REACH-IT (skip this step if your company already has an account). Log into REACH-IT. From the Menu, select “Upload a IUCLID dossier” under “Downstream user notification of authorised uses.” Follow the submission wizard.
