On May 21, 2024, the European Commission issued Directive (EU) 2024/1416, which updated Article 39(a) "On the reduction of cadmium-based semiconductor nanocrystals used in display lighting equipment" in Annex III of the EU RoHS Directive 2011 /65/EU. Cadmium selenide for quantum dots (cadmium for display area <0.2ug/mm2)" exemption clause is valid, and a new 39(b) exemption clause is added. This directive will take effect on the 20th day after the announcement.
Annex III of Directive 2011/65/EU is amended as follows:
exemption clause
