Key takeaway
What This Development Means
The EU Court has annulled the carcinogenic classification of titanium dioxide in powder form, removing a major compliance hurdle. This ruling brings regulatory relief to multiple industries, though future reclassification remains possible if new evidence justifies it.
Why was titanium dioxide removed from the EU's list of suspected carcinogens?
The Court found that the European Commission made a legal error in relying on incomplete scientific data to classify titanium dioxide as a suspected carcinogen by inhalation. The ECHA's Risk Assessment Committee failed to fully assess all relevant factors, leading to the annulment.
Does this ruling mean titanium dioxide is now safe to use without restrictions?
Not necessarily. While the carcinogen label under CLP has been annulled, businesses must still assess health risks under REACH and other frameworks. Future scientific evaluations could result in new classification proposals, so vigilance remains essential.

The Court of Justice of the European Union (CJEU) has upheld a 2022 judgment annulling the classification of titanium dioxide in certain powder forms as a suspected carcinogen. Delivered on 1 August 2025, the ruling effectively invalidates the European Commission’s labelling requirement under the CLP Regulation, with significant implications for chemicals manufacturers, importers, and downstream users across multiple sectors.
The Court confirmed that the European Commission had erred in basing its 2019 classification on insufficient scientific grounds, leading to legal challenges from titanium dioxide producers and industry stakeholders. The decision removes an important labelling burden affecting products in paints, foodstuffs, toys, pharmaceuticals, and cosmetics.
Scientific Grounds And Regulatory History
The reclassification of titanium dioxide was initiated by the French health agency ANSES, which in 2016 proposed its classification as a Category 1B carcinogen by inhalation. The following year, the European Chemicals Agency (ECHA) Risk Assessment Committee issued an opinion supporting a less severe Category 2 classification, which was ultimately adopted in Commission Delegated Regulation (EU) 2020/217.
This regulation required substances in powder form containing 1% or more of titanium dioxide particles with diameters ≤10 μm to be labelled with the hazard statement H351 (inhalation). However, the General Court ruled in 2022 that the Commission had committed a “manifest error” in evaluating a key scientific study. That judgment was appealed by France and the European Commission, but dismissed by the CJEU in this latest ruling.
Impact Across Supply Chains And Compliance Regimes
The ruling has broad ramifications for businesses involved in the production and use of titanium dioxide. As a widely used white pigment, titanium dioxide is essential in coatings, plastics, paper, pharmaceuticals, and food packaging. Companies were previously obligated to alter product labelling and Safety Data Sheets (SDS), incurring operational and reputational costs.
The annulment lifts those obligations, at least for now. However, professionals should remain alert: while this ruling removes the existing classification, it does not prevent future reclassification efforts should stronger evidence emerge.
Regulatory Clarity And Next Steps
Although the Court upheld the General Court’s findings, it also noted that the lower court had exceeded its judicial review boundaries. Nevertheless, the final outcome stands: the titanium dioxide classification as a suspected inhalation carcinogen is annulled.
Regulatory teams should reassess ongoing compliance strategies, update risk communications, and monitor any new scientific assessments or reclassification proposals from ANSES or ECHA.
