Progress report on ChromeXtend

Please note the following deadline: Measurement results must be submitted by December 18, 2021

Over recent months, K.Walter has supported the implementation of the CTAC authorization in Europe and assisted users in a variety of ways. Across the board, the chromium trioxide exposures that have been measured have been low, and well below the legal limits.


K.Walter would like to remind chromium trioxide users once again that measurement results must be submitted to the European Chemicals Agency (ECHA) via REACH-IT by December 18. To assist in this process, K.Walter is once more offering support with completing the ECHA measurement template and uploading the data.


Since K.Walter submitted its application for authorization to the ECHA in February 2021, the application has been processed and handled by various ECHA bodies. There has been constructive dialog between K.Walter and the ECHA at various points and K.Walter has been able to answer the last substantive questions satisfactorily. Based on initial discussions about operating conditions and risk reduction measures, it appears that the ECHA views the high process standards and safety measures in gravure and embossing electroplating as credible and adequate.


We anticipate that the ECHA will complete its report on our application in the next few weeks and pass it on to the European Commission. Based on the ECHA recommendation, the Commission will evaluate the application once again and a legal text will then be drawn up. This text will be passed into law when the member states in the European Commission’s REACH Committee vote on it. Due to the large number of applications for authorization that have been presented to the Commission, it is currently anticipated that a final decision will be reached at the end of 2022/beginning of 2023.


If you have any questions about the implementation of the current chromium regulations, please contact Ms. Sylvia Berger (, +49 (0)89 785 96 188).
