As you are aware, MoCon prepared the technical data (mandatory hazard dataset and chemical safety report for each substance in the MoCon substance portfolio) that each intending registrant will refer to when submitting its own registration. 

Since March 2010 all REACH-registrations must be submitted using IUCLID5 software package.  Now in 2015 a new IUCLID version 5.6  is available free-of-charge from the European Chemicals Agency (ECHA) on

We recommend that all intending to register install IUCLID well in advance of their first intended REACH-registration date, in preparation for when you will need to use it to prepare your joint-submission registration file.  For the avoidance of doubt, please be clear that the Molybdenum Consortium prepared the Lead Registrant REACH-registration submission, but all companies that jointly-submit (i.e. refer to the Lead Registrant submission) must prepare their own joint-submission REACH registration file using IUCLID5.6

 Installing and learning how to use this software, so that you can understand and then achieve what you need to do to prepare your successful joint-submission registration file is a challenging task.  You are strongly encouraged not to leave this activity until the last minute!
