July 20, 2021Scott StephensBlog

The European Chemicals Agency (ECHA) announced that it has added eight new entries, including several substance groups, to the Candidate List of Substances of Very High Concern (SVHCs) on 8 July 2021.

Verisk 3E Review 

The list, which is updated twice a year, now contains 219 entries that have been identified as SVHCs under the REACH Regulation's Title VII Authorisation process.
The new substances and substance groups—along with their reasons for inclusion as SVHCs (citing relevant articles of Regulation (EC) No. 1907/2006 (REACH)) and example uses

PBT (Article 57d)

vPvB (Article 57e)

Endocrine disrupting properties (Article 57f - human health and environment)

Preparation of lubricant additive materials and of fuel system cleaners


123-91-1 Carcinogenic (Article 57a)
Equivalent level of concern having probable serious effects to the environment (Article 57f -environment) 
Equivalent level of concern having probable serious effects to human health (Article 57f –human health)


4,4'-(1-methylpropylidene) bisphenol

77-40-7 Endocrine disrupting properties (Article 57f - human health and environment) Not registered under REACH 
May be used in manufacture of phenolic and polycarbonate resin

Separately, ECHA has added a note stating that a technical error led to the substance with CAS RN 251-823-9 (tetrahydro-4-methylphthalic anhydride) being mistakenly associated to an earlier Candidate List entry (hexahydromethylphthalic anhydride [including cis- and trans- stereo isomeric forms and all possible combinations of the isomers]). The ECHA says the associated substance has been removed from the Candidate List.

Verisk 3E Analysis

Companies may have legal obligations resulting from the inclusion of substances in the Candidate List. These obligations may apply to the listed substance on its own, in mixtures, or in articles.

In particular, any supplier of articles containing a Candidate List substance above a concentration of 0.1% (weight by weight) has communication obligations toward customers down the supply chain and consumers. In addition, importers and producers of articles containing such substances have six months from the date of their inclusion in the Candidate List (8 July 2021) to notify the ECHA. Suppliers of substances on the Candidate List (supplied either on their own or in mixtures) have to provide their customers with a safety data sheet.

As of 5 January 2021, suppliers of articles on the EU market containing Candidate List substances in a concentration above 0.1% (weight by weight) must notify these articles to the ECHA’s SCIP database. This duty comes from the Waste Framework Directive.
