Verabschiedete Gutachten und bisherige Konsultationen zu Zulassungsanträgen

This page provides further information on the applications for authorisation or review reports, which have undergone consultation. The applications for authorisation are in the opinion development phase until the final opinions of the Committees for Risk Assessment and Socio-economic Analysis have been adopted and sent to the European Commission. Its decision-making process can be followed through the comitology register, where further information is published about the REACH Committee's past and upcoming meetings.

On 1 February 2020, the United Kingdom (UK) withdrew from the EU. The transition period provided by the withdrawal agreement ended on 31 December 2020. As of 1 January 2021, an application for an authorisation submitted by a person established in the UK (except Northern Ireland) is no longer valid in the EU, unless that application has been transferred to a legal entity established in the EU or Northern Ireland before the end of the transition period. Therefore, authorisation applications and decisions in so far as these concern persons established in the UK (except Northern Ireland) are no longer considered valid.

Substance Details

Name: Chromium trioxide
EC Number: 215-607-8
CAS Number: 1333-82-0
Entry Nr in Annex XIV: 16
Use name: Chromium trioxide-based functional chrome plating of components with diverse geometries and dimensions, requiring specialized equipment and process knowledge, for applications in demanding industry sectors such as mechanical engineering, metalworking and processing, aerospace, automotive, and medical technology.
Broad information on use applied for (conditions of use and function): Betz-Chrom GmbH is a medium-sized job plating company using chromium trioxide for the functional chrome plating of components spanning several industry sectors, including, for example, plastics production, mechanical engineering, metalworking, hydraulics, textiles, automotive and printing. In these applications, where machines and their parts are used under highly demanding conditions (e.g. high temperature, constant friction and impact, exposure to acids, etc.), the deposited chrome layer acts as a barrier against corrosion and increases the components’ resistance to wear, extending their lifetime and ensuring their correct and safe functioning. Furthermore, Betz Chrom provides services for the refurbishment of worn-down components, consisting of the reapplication of chrome coating on component’s surface to extend its overall service life.

Functional hard chrome plating offers various advantages in terms of the plating process, including good bath stability, possibility to remove worn-down coating and reapply a new one, variable layer thickness and possibility to offer different surface finishes. The result of the functional chrome plating process is a metallic chrome coating which provides a range of desired properties to the finished article (e.g. hardness, wear resistance, corrosion resistance, microcracking for tribologically advantageous properties such as dry-running, sliding and anti-adhesion). These key functionalities constitute important traits that help to ensure the safety and correct functioning of components and machines used in several industry sectors, ultimately extending their service life.
