The European Chemicals Agency (ECHA) has recommended that the European Commission add four substances—including the widely used chemical melamine—to the REACH Authorisation List, a move that could significantly tighten regulations for companies across Europe.

The recommended substances—Barium diboron tetraoxide, Phosphorodithioate, Diphenyl phosphine oxide, and Melamine—have been identified as the highest-priority chemicals of very high concern (SVHC) under EU rules. Once added, companies will need to apply for authorisation to continue using them.

Melamine’s inclusion follows extensive industry consultation throughout 2024. Despite concerns from sectors relying on the substance, ECHA determined that most common uses—primarily as an intermediate—do not require authorisation under REACH. However, remaining uses could trigger a substantial compliance workload for businesses.

“When assessing the consequences of listing a substance, it’s crucial to weigh legal requirements against real-world uses,” said Ofelia Bercaru, ECHA Director for Prioritisation and Integration. “Balancing the risks posed by melamine with its continued use is ultimately a policy decision for the Commission and Member States.”

ECHA’s recommendations now move to the European Commission, which will decide which substances to formally add to the Authorisation List and under what conditions. The authorisation process is designed to phase out high-risk chemicals where safer alternatives exist, while ensuring controlled use until replacements are feasible.
