Chromium VI authorisation: information sessions for groups of applicants

Chromium VI authorisation

ECHA August 24, 2022

As a high number of authorisation applications are expected for hexavalent chromium (Cr(VI)) uses in the coming years, the way of information sessions for these uses will be changed. In the future, will organised for groups of several applicants.

The first group session will take place on 15 February 2023, and more will be organised after that based on need. Future dates will be announced in the bulletin.

Chromium trioxide – REACH Authorisation Deadlines

Chromium trioxide – REACH Authorisation Deadlines

Chromium trioxide (EC No. 215-607-8; CAS No. 1333-82-0) is widely used in plating and surface treatment.

Notifications from 1 026 sites across Europe submitted by May 2021 confirm that chromium trioxide is still widely used in functional or hard chrome plating and surface treatment. The annual usage is estimated to be 7 000 tonnes. The substance of very high concern was placed on the Authorisation List in 2013 and its use has needed a specific authorisation in the EU since 2017.

By notifying the uses to ECHA, companies confirm that they follow the conditions for use set in the authorisation decisions granted to their suppliers. As part of the conditions, they must inform ECHA by the end of 2021 how their workers are exposed to chromium trioxide. This information will help companies to protect their workers even better by minimising their exposure to the carcinogen.

In December 2020 European Commission published 2 decisions granting authorisation to use the chemical until September 2024.

Enforcement authorities can now carry out inspections as necessary.

There are 2 principal duties for companies using chromium trioxide:

  1. Apply for REACH authorisation in time;
  2. Comply with the conditions comunicated by suppliers through extended safety data sheets.

The chromium trioxide applications for REACH authorisation by companies is now accelerating.

Actual Applications for authorisation – current consultations:

Joint authorisation originally applied by CETAC consortium (and others) will be ineffective after September 2024.

Ekotox Centers offer complex services to prepare all necessary documents on behalf of the customers. To stay on the market there is need for immediate action!

On the same time there is a duty to comply with the safety measures and operational conditions – requirements defined for downstream users by eSDS. To be sure that all is in compliance Ekotox Centers provide support to manage „Internal Dossiers for REACH Authorisation Compliance“ (IDRAC).

The five substances are:
  • Tetraethyllead (TEL) (EC 201-075-4, CAS 78-00-2);
  • 4,4′-bis(dimethylamino)-4”-(methylamino)trityl alcohol [with ≥ 0.1% w/w of Michler’s ketone (EC 202-027-5) or Michler’s base (EC 202-959-2)] (EC 209-218-2, CAS 561-41-1);
  • Reaction products of 1,3,4-thiadiazolidine-2,5-dithione, formaldehyde and 4-heptylphenol, branched and linear (RP-HP) [with ≥ 0,1% w/w 4-heptylphenol, branched and linear (4-HPbl)] (EC -, CAS -);
  • 2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (DOTE) (EC 239-622-4, CAS 15571-58-1); and
  • Reaction mass of 2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate and 2-ethylhexyl 10-ethyl-4-[[2-[(2-ethylhexyl)oxy]-2-oxoethyl]thio]-4-octyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (reaction mass of DOTE and MOTE) (EC -, CAS -).

The amendment of the Authorisation List (Annex XIV to REACH) was published on 11 April in the EU’s Official Journal.

Companies that want to continue using these substances after the agreed sunset dates will need to apply for authorisation.

Case study: Impacts of REACH  authorisation of trichloroethylene

Case study: Impacts of REACH authorisation of trichloroethylene

This report takes a detailed look at the impacts of REACH authorisation on trichloroethylene (TCE) from its inclusion on the Candidate List in 2010 until January 2022.

The need to obtain authorisation significantly reduced the use of TCE. The annual use of TCE in the EU has dropped more than 95 % in the past 12 years.

Updated application for REACH authorisation formats

Updated application for REACH authorisation formats

ECHA has published an updated format for companies to use when applying for authorisation to use substances of very high concern (SVHCs).

The new format combines the analysis of alternatives, the socio-economic analysis and, when relevant, a substitution plan into a single document. 

The new format is easier for applicants to fill in. The possibility to submit separate documents has been removed making the application process more efficient and the documents more coherent. The instructions on confidentiality have also been updated.

At the same time, the opinion format for the Committees for Risk Assessment (RAC) and for Socio-Economic Analysis (SEAC) has been revised to take the General Court’s judgments in two authorisation cases into account.

The judgments concerned situations where suitable alternatives are available in general and the applicants would need to submit a substitution plan. As requested by the European Commission, the opinion format also includes “a conclusion on whether or not the applicant has shown that the benefits for society from using the substance outweigh the risk to human health or the environment”.

Applicants should start using these formats immediately.

However, applications may be submitted in the old format until the end of 2021 if applicants have already finalised or are close to finalising the content of their application.
