Is your dispute pending? You can still submit a dossier by 31 May
If you have recently filed a data-sharing dispute to ECHA, it may be that the decision is not finalised before the 31 May 2018 registration deadline. This would mean that you are not able to submit a complete registration in time. However, you can still make a submission so that you can continue on the market until the Agency has assessed your case.
Further information can be found in the ECHA news release.
