Global Chromates Consortium for Aerospace
The Global Chromates Consortium for Aerospace (GCCA) was formed in 2015 to prepare and submit Applications for Authorisation (AfAs) under the European REACH regulation, and to provide guidance for compliance activities for the use of hexavalent chromium substances that are critical to the aerospace, defence and aeroderivative sectors, but sourced through supply chains that are not covered by other AfAs.
The GCCA Authorisation ToolboxGCCA has developed an Authorisation Toolbox aimed at supporting downstream users to address their requirements under the GCCA Authorisations. Over the next few weeks we’ll be offering Webinars and supporting guidance on using this toolbox.

On 9–10 July 2019, the European Commission voted to approve the REACH authorisations sponsored by the Global Chromates Consortium for Aerospace (GCCA) covering use of chromium trioxide, sodium chromate, potassium dichromate and sodium dichromate containing products imported into the EEA for aerospace and defence use, granting a 7-year review period from the Sunset Date of 21 September 2017.
The GCCA-sponsored authorisations for chromium trioxide and sodium chromate entered into force (‘date of adoption’) in the EU (and wider EEA) on 29 October 2019 and potassium dichromate entered into force on 5 November 2019. The entry into force of the sodium dichromate authorisation is expected to follow early in 2020. As such, the clock is now ticking on a number of actions that will need to be taken by downstream users.
Further, during the 19-20 November 2019 REACH Committee Meeting, the GCCA-sponsored authorisations for dichromiuim (tris)chromate and strontium chromate were voted on and approved by the European Commission’s REACH Committee. Although the exact timing is not yet known, these authorisations are expected to enter into force in the first quarter of 2020.
