Webinar: Preparing for imminent REACH authorisations, 25 November 2019

GCCA is hosting an informational webinar regarding the European Commission approval of four of the six REACH Authorisations sponsored by GCCA. The webinar will help downstream users understand how these authorisations fit into the universe of aerospace and defense authorisation applications and relevant requirements, as well as the schedule for compliance. Date: Tuesday, 25 November 2019, 9:00 am EST / 2:00 pm GMT / 3:00 pm CET. Please contact Dianne Koch Green (dgreen@ramboll.com) to register.

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 authorisations for Chromium trioxide and Sodium chromate entered into force (‘date of adoption’) in the EU (and wider EEA) on 29 October 2019 and the authorisations for Potassium dichromate and Sodium dichromate are expected to closely follow. This will start the clock ticking on a number of actions that will need to be taken by downstream users. More information can be found in the GCCA News Bulletin No. 2019-01 and 2019-02 and below.  Further information will be provided here shortly.

[1]  This authorisation covers only liquid formulations.

[2] Aerospace sector includes companies principally engaged in carrying out the design, development, manufacture, maintenance, modification, overhaul, repair, or support of civil or military aerospace and defence equipment, systems, or structures, plus any derivative uses.

[3] The authorisation for the use of chromium trioxide is not granted for chemical conversion and slurry coating applications by the aerospace sector where none of the key functionalities listed in the use is necessary for the intended use.

[4] The authorisation for the use of sodium chromate for sealing after anodizing, chemical conversion coating, pickling and etching applications by the aerospace sector is not granted for this use where none of the key functionalities listed in the use is necessary.

[5] Boeing Distribution, Inc. (formerly Aviall Services Inc.) is also an applicant for additional chromate authorisations, including Chromium trioxide (0032-010032-020032-030032-040032-050032-06), Strontium chromate (0046-010046-02), Potassium hydroxyoctaoxodizincatedichromate (0047-010047-02), and Pentazinc chromate octahydroxide (0118-010118-02). These have not yet been decided by the European Commission.
