The list of Candidate Substances – Candidate List – has been updated with eight hazardous chemicals

Security and Protection

The list of substances of very high concern now contains 219 chemicals that can harm both people and the environment.

Helsinki, July 8, 2021 – Some of the newly added substances are used in consumer products, such as cosmetics, perfumed articles, rubber and textiles. Others are used, for example, as solvents, flame retardants or in the manufacture of plastic products. Most of them have been added to the Candidate List because of their hazards to people, being reproductive toxicants, carcinogens, respiratory sensitizers or hormonally active agents.

Companies must fulfill their legal obligations and ensure the safe use of these chemicals. In addition, they must notify ECHA – under the Waste Framework Directive – if their products contain substances of very high concern. This notification is submitted to ECHA’s SCIP database and the information will then be posted on the Agency’s website.

Below are the substances added on July 8, 2021:

Background Information


The Candidate List includes substances of high concern that may have serious effects on our health or the environment. These substances could be included on the Authorization List (Annex XIV) in the future, which means companies would have to apply for permission to continue using them.


Under REACH, companies may have legal obligations when their substance is included – on its own, in mixtures or in articles – on the Candidate List. Any supplier of articles containing a Candidate List substance above a concentration of 0.1% by weight must provide sufficient information to their customers and consumers to enable safe use.


Importers and manufacturers of articles containing a Candidate List substance have six months from the date of its inclusion on the list (July 8, 2021) to notify ECHA. Suppliers of Candidate List substances (supplied alone or in mixtures) must provide their customers with a safety data sheet.


Beginning January 5, 2021, article suppliers must notify substances of very high concern in their articles to ECHA’s SCIP database under the Waste Framework Directive.


More information on these obligations and related tools is available on ECHA’s website.
