On 1 January 2026, the European Union enacted the ‘one substance, one assessment’ (OSOA) laws, creating a unified framework for chemical safety assessment across EU legislation. The new rules cover products such as toys, food, pesticides and biocides, aiming for consistent, transparent and efficient evaluations. A core element is a common data platform on chemicals, expected to be operational within three years, which will centralise data from various EU laws and be accessible to all stakeholders. The package also clarifies task allocation among EU chemicals agencies, reduces duplication, and strengthens scientific cooperation. Additionally, a monitoring and outlook framework will use indicators and early‑warning tools to detect emerging chemical risks sooner. The reforms stem from the 2020 Chemicals Strategy for Sustainability, part of the EU’s zero‑pollution ambition.
