Submit a dispute claim

Please note that ECHA will be closed from 23 December 2025 to 2 January 2026. Due to this end of the year closure, ECHA is not able to start processing dispute claims before 5 January 2026.

After that date, ECHA will contact claimants with information regarding the procedure and applicable deadlines. In any event, ECHA encourages you to continue your efforts to reach a voluntary agreement with the other party.

Before you start filling in the webform, make sure you have the following information at hand:

  1. Your asset number (EU-0000000-0000) as stated in the inquiry communication you have received from ECHA.
  2. Your contact details and contact details of the other party.
  3. Records of the documentation (.zip file or .pdf document):
    • correspondence with the other party demonstrating the efforts made to reach an agreement;
    • communication informing the other party about lodging a dispute at ECHA.

After submitting the webform, you will receive an automatic email confirmation.

ECHA encourages you to continue negotiating even after you have filed a dispute, as an ECHA decision will not satisfy any party to the dispute in a way that a voluntary agreement would.
