The 27th May of 2008 the guidance on registration has been updated in line with the new Commission interpretation on aggregation of tonnages. Only Representatives (OR) that represent multiple non-EU producers must submit a separate registration for each of these substance producers.
The Commission announced further changes to the Only Representative rules, which will be included in the guidance on registration in due time (exp. fall 2008).
If you are a non-EU producer make sure to comply with these changes in the guidance on registration.
