Oeko-Institut has opened a consultation on the re-evaluation of two RoHS Expemptions for Cadmium Quantum Dots


The Oeko-Institut has been authorized by the European Commission to evaluate expemption requests and determine if the substances meet the criteria set out on article 5(1) of the directive. The organization opened a consultation to evaluate two request to renew select exemptions for cadmium quantum dots (Cd QD) under the Restrictions of Hazardous Substances in Electrical and Electronic Equipment Directive (RoHS2).

In 2013, Oeko-Institut assessed the renewals request that covered the use of cadmium quantum dots in light-emiting diode (LED) displays and lighting. The two exemption requests are:

Oeko-Institut recommended ‘not granting an exemption for Cd in QD applications to be used in solid state lighting’ while granting an exemption on the use of Cd QD in displays ‘where the cadmium per display screen area is limited to less than 0.2 μg/mm²’. The European Commission submitted a delegated act to the European Parliament in January 2015 that would implement this recommendation.


However, Members of the European Parliament objected to the delegated act and called for a swift reassessment of the existing exemption […] against the conditions of article 5(1)(a)’ in which the conditions for exempting a substance from RoHS2 are laid out. This has sent the exemption requests back to Oeko-Institut who has opened a new consulation on the joint revaluation of these two exemptions with a 8 January 2016 deadline.
