News Brief
On July 15, 2025, Brussels time, the European Commission published amendments (EU) 2025/843 to the Regulation (EU) 2019/1021. According to the amendments, UV-328 is now formally included in the controls under Annex I of the regulation.
What Is UV-328?
UV-328 is a UV stabilizer that prevents discoloration and aging of various surfaces when exposed to ultraviolet radiation. It is primarily used in paints and coatings, and as an additive in various plastics (e.g., PVC, polyester). It can also be found in LCD panels and instruments installed in vehicles, as well as in resins for interior and exterior automotive components.
Due to their persistence in the environment and potential adverse effects on human health, both substances have been listed in Annex A (Elimination) of the Stockholm Convention, which aims to stop all production and use except for specific exemptions.
