While there has been debate around the difference in approach of REACH and RoHS to substance restrictions, REACH is unlikely to "swallow RoHS up".
Industry was said to favour the REACH approach during consultations around substance restrictions as part of the review of the scope of RoHS undertaken by Oko Institut on behalf of the European Commission.
RoHS restrictions are easier to adopt than REACH and so many EU Member States still prefer the RoHS approach.
In respect of the review, Oko were expected to publish their findings in early June. While discussions on additional substances are now complete the study on exemptions is on going and is not due to finish until September.
It is fair to say that industry is not totally happy about some of Oko's proposed recommendations on substance restrictions!
