The European Chemicals Agency (ECHA), to protect health and the environment, recommends that the European Commission adds four substances, including melamine, to the REACH Authorisation List. Once added to the list, companies must apply for authorisation if they wish to continue using the substances.

Helsinki, 18 November 2025 – The recommendation includes the following substances:

1,Barium diboron tetraoxide;

2,S-(tricyclo[5.2.1.0 2,6]deca-3-en-8(or 9)-yl) O-(isopropyl or isobutyl or 2-ethylhexyl) O-(isopropyl or isobutyl or 2-ethylhexyl) phosphorodithioate;

3,Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide; and

4,Melamine.

ECHA has selected these substances from the Candidate List of substances of very high concern (SVHC) for this recommendation because, following the agreed approach, they are of the highest priority.

The inclusion of melamine in the draft recommendation was comprehensively commented on by sectors using the substance during the 2024 consultation period but the decision to include it was made after careful consideration of all the issues.

Ofelia Bercaru, Director for Prioritisation and Integration, said:

“When assessing the consequences of including a substance in the Authorisation List, it is important to consider the scope of the legal requirement. In most of its applications, melamine appears to be used as an intermediate, which does not require authorisation under REACH.

“However, applications for authorisation for the remaining uses may potentially create a significant workload for companies and authorities. ECHA is aware of the challenges and considered that balancing the risks posed by melamine with its continued use, requires a policy decision by the Commission and EU Member States.”

More information about the reasons for recommending these substances for authorisation and about their uses is available in ECHA’s recommendation and related documents.

Background

ECHA has the legal obligation to regularly recommend substances from the Candidate List for the Commission to include in the Authorisation List. Before sending its recommendation to the Commission, ECHA considers comments received during a three-month consultation and the opinion of the Member State Committee.

The Commission will decide which substances are included in the Authorisation List and what conditions apply to each substance. If a substance is included in the Authorisation List, it can only be placed on the EEA market or used after a given date, if an authorisation is granted for a specific use.

The authorisation process aims to enhance the substitution of substances of very high concern when technically and economically viable alternatives are available. Until this is achieved, the goal is to ensure proper control of risks for human health and the environment.
