[Regulatory Update] CJEU upholds first-instance judgment annulling carcinogenic classification of certain powder-form TiO₂

Source:Court of Justice of the European Union (CJEU)
On 1 August 2025, the Court of Justice of the European Union (CJEU) upheld the General Court's judgment annulling the European Commission's measure classifying certain powder forms of titanium dioxide (TiO₂) as a carcinogen. This does not simply mean "TiO₂ has been found safe." What is at issue is the harmonised CLP classification for specific powder forms, and the Court's ruling concerns the classification procedure and its legal requirements.
Editor's View

In chemicals regulation, it is not only the scientific hazard assessment that matters for corporate compliance, but also the procedure by which that assessment is translated into a legal classification. Companies using TiO₂ need to continuously monitor its legal status, since a change to its CLP classification can have knock-on effects on SDSs, labelling and product management; "scientific assessment," "regulatory classification" and "judicial review of a classification measure" need to be read as distinct layers.

This is the foundational law implementing the UN Globally Harmonized System (GHS) for the classification and labelling of chemicals across the EU. It sets out how to identify the hazards of substances and mixtures, requirements for pictograms and hazard statements on labels, packaging requirements, and the obligation to submit poison centre notifications (PCN).
