EU RoHS launches public consultation on cadmium exemption!


Time:

2023-12-26

The European Union has provided public feedback on the exemption for cadmium in Annex III of the RoHS Directive (2011/65/EU), proposing to revise the exemption for cadmium in item 39 (a) and add an exemption clause in item 39 (b).

On December 18, 2023, the European Commission provided public feedback on the exemption for cadmium in Annex III of the EU RoHS Directive (2011/65/EU), proposing to revise the exemption for cadmium in Article 39 (a) and add an exemption clause in Article 39 (b). The draft will be open for 4 weeks of feedback (December 18, 2023 to January 15, 2024).

 

 

The clauses in the draft are as follows:

Entry Exemption Scope and Deadline of Application
39(a) Cadmium selenide in cadmium based semiconductor nanocrystal quantum dots used to reduce conversion in lighting equipment (display area less than 0.2 micrograms/square millimeter) Applicable to all types, expiring 18 months from the date of new directive release
39(b) Cadmium used for display and projection, directly deposited on LED semiconductor chips to reduce conversion of semiconductor nanocrystal quantum dots (less than 5ug of cadmium per square millimeter on the surface of luminescent LED chips), with a maximum content of 1 milligram per device. Applicable to all types, expiring on December 31, 2027

 

 

Background:

According to the Authorization Directive (EU) 2017/1975, the European Commission approved an exemption for the use of cadmium selenide in semiconductor nanocrystal quantum dots used to reduce conversion in display lighting equipment ("Current Exemption"), listed in Annex III, Article 39 (a) of Directive 2011/65/EU. Exemption from expiration on October 31, 2019.

On September 29, 2017, April 29, 2018, and April 30, 2018, the European Commission received an extension exemption application submitted in accordance with Article 5 (5) of Directive 2011/65/EU, and the exemption remained valid until a decision was made on the renewal application.

The evaluation concludes that the current alternative "chip" technology for lighting equipment is reliable and achieves similar performance levels. The conclusion of the evaluation for these applications is that the benefits of exemptions will not exceed their negative impacts on the environment, health, and consumer safety.

The evaluation further concludes that there is currently no reliable alternative for certain specific technologies, such as micro displays. Therefore, it is appropriate to grant cadmium exemption in semiconductor nanocrystal quantum dots directly deposited on LED semiconductor chips for display and projection applications that reduce conversion. It is expected that by the end of 2027, substitutes for these cadmium quantum dot applications may emerge.
