Guidance and support

ADCR Guidance Materials

To support compliant use of the five authorised ADCR chromate substances, ADCR has developed several supporting documents.


On this page you will find Exposure Scenarios,  several flow charts, and additional guidance documents as well as developed monitoring template.


ADCR EEA and GB Guidance


ADCR has developed two guidance documents 'Guidance on ADCR Authorisation decisions for Downstream Users of soluble chromates in EEA' and 'Guidance on ADCR Authorisation decisions for Downstream Users of soluble chromates in GB'.


These two guidance documents aim to provide information on the ADCR Authorisations for soluble chromates in EEA and GB and to support Downstream Users (DUs) in ensuring compliance with the required conditions of the ADCR EU and UK REACH Authorisations.


ADCR hosted a webinar on 22 May 2025 presenting these two Guidance documents.

ADCR EEA and GB Monitoring Guidance


In addition to the two guidance document above ADCR has also developed a Guidance document for ADCR Downstream User sites in the EEA and GB for conducting monitoring of worker exposure and environmental emissions.


ADCR hosted a webinar on 22 May 2025 presenting this Guidance documents.

ADCR EEA and GB Exposure Scenarios


ADCR has developed the Exposure Scenarios to be placed in annex of the Safety Data Sheet (SDS)  for Chromium Trioxide (CT), Dichromium Tris(Chromate) (DtC), Potassium Dichromate (PD), Sodium Chromate (SC) and Sodium Dichromate (SD) used in the EEA and GB.


Depending on the authorised use, Application Holders and Downstream Users will have to identify the appropriate Exposure Scenarios (ES) to be annexed to their SDS, delete the non-relevant uses in the overview table (page 3) and the corresponding ES in the core document. The introductory section (pages 1 and 2) should be kept as an introduction of the annex.


Currently, only the English versions are available for the EEA, but translations into several other EU languages are being prepared and will be published over time.

ADCR Recordings


ADCR has produced several supporting recordings and published them on YouTube: ADCR Consortium - YouTube.

Overview of obligations in EC implementing Decisions for ADCR Authorisations and ADCR - How to execute at a site | Ensure compliance with granted ADCR Authorisations


The slides used for the overview recording is provided as a pdf:

Overview of obligations in EC implementing decisions for ADCR Authorisations


The overview recording, provides information on the ADCR Authorisations, and walks through the implementing decisions in high level detail.


The second recording, presents two guidance flow charts for ensuring compliance with the required conditions  of the ADCR EU REACH Authorisations and the guidance flow chart on feasibility studies (see below)


The third recording, presents 'How to complete the ADCR Monitoring Template for surface treatments'


ADCR Flow Charts


ADCR has developed a guidance flow chart to support compliance with the conditions found in the implementing decisions. ADCR T1 EU Implementing conditions guidance flow charts 01052025.


A flow chart is also developed to give guidance on the feasibility studies, where required from the implementing decisions. ADCR T1 EU feasibility study guidance flow charts 01052025.


To support downstream users ADCR has developed flow charts to support identification of the relevant REACH Authorisation Number for each use and substances.

UK HSE topics on LEV


The UK Health and Safety Executive have useful information and advice on how to Commission your local exhaust ventilation (LEV) system, presented in their topics page on Local exhaust ventilation (LEV): workplace fume and dust extraction. There is much useful information presented, which is to a large extent also applicable for an EU site.

ADCR FAQ Document


The ADCR Consortium developed an ADCR FAQ Document (pdf version 26 March 2025, replaces previous version of 16 August 2024) answering many questions related to the current applications and supply chain questions.

ADCR Factual Communication


In July 2024 ADCR provided a Factual Communication providing concise information on the submitted ADCR dossiers. As Authorising Decisions have now been provided, the Factual Communication is not as relevant anymore.
