EU TiO2 Carcinogen Classification — 2022 Update
The EU's 2022 TiO2 classification as a Category 2 carcinogen (inhalation route) created compliance complexity — but only affects respirable powder forms.
In February 2020 (effective October 2021, with grace period to 2022), the European Commission added titanium dioxide to Annex VI of the CLP Regulation (1272/2008) with the classification "Carc. 2; H351 — Suspected of causing cancer by inhalation."
This classification triggered substantial regulatory and commercial debate, with multiple legal challenges. In November 2022, the EU General Court partially annulled the classification on procedural grounds. The European Commission appealed; the Court of Justice ruled in 2024.
Current status (2025): The Carc. 2 classification applies to TiO2 in powder form containing 1% or more of particles in respirable size range (≤ 10 μm aerodynamic diameter). The classification does NOT apply to: - TiO2 in pigmented mixtures (paints, plastics, inks at point of use) - TiO2 in non-respirable forms (granulated, beaded, slurry forms) - TiO2 already incorporated into finished articles
Practical implications for TiO2 buyers:
For powder TiO2 (the main commercial form): - Labeling required: H351 hazard statement, GHS08 health hazard pictogram - Safety Data Sheet (SDS) updated to reflect classification - Workplace exposure controls per Carc. 2 substance handling - No restriction on use — the classification is informational, not a ban
For finished products containing TiO2: - Paint (liquid): if TiO2 content > 1% and could be inhaled in finished product context, classification considered. Most consumer paint is exempt because it's not in respirable form when applied normally. - Plastic compounds with TiO2: typically exempt (TiO2 is incorporated and not respirable) - Powder coatings: applied as powder, but workplace handling controls apply; finished cured coating is not affected - Cosmetic powders / aerosols: subject to separate Cosmetic Regulation review
For TiO2 trade: - REACH registration remains the dominant regulatory framework - Import to EU still permitted with proper labeling and SDS - No quantitative restriction or ban - CLP-equivalent classifications in UK (post-Brexit), some other jurisdictions
SEMITI compliance: - All SEMITI TiO2 grades are REACH-registered - SDS includes current CLP classification status - Documentation provided for EU import: REACH letter, classification statement, exposure scenarios
Where exemptions apply: The EU exemption for non-respirable forms is significant. Suppliers can offer: - Slurry forms (e.g., SEMITI SL70 — 70% solids in water) — exempt because not respirable - Beaded / granulated TiO2 — exempt - Pre-dispersed concentrates for cosmetics — exempt
Some buyers have switched to slurry forms partly to simplify their internal regulatory compliance. The mechanical handling advantages (no dust) align well with the regulatory simplification.
Industry response: The TDMA (Titanium Dioxide Manufacturers Association) has worked extensively on: - Workplace exposure data (REACH-CRO under REACH Annex VII) - Toxicological studies (multiple OECD-compliant studies) - Communication with regulators on the scientific basis of the classification
The current state is a workable compromise: the classification stands for powder, exemptions cover most finished-product use, and the underlying scientific debate continues.
Bottom line for buyers: - Yes, the classification applies to powder TiO2 in EU - No, it doesn't ban or substantially restrict TiO2 use - Update your SDS and labeling per CLP requirements - Consider slurry form for plants where regulatory simplification is valuable - REACH registration is the dominant ongoing compliance requirement
