ECHA Issues New Guide on Classifying and Labeling Titanium Dioxide

The classification and labeling requirements for titanium dioxide (TiO₂) changed in February 2020. As of 1 October 2021, following Delegated Regulation (EU) 2020/2017, new classification and labeling requirements enter into force.

Classification Parameters

The substance TiO₂ must be classified as carcinogen if inhaled (Carc. 2, H351 (inhalation) when supplied on its own or in mixtures, where the substance or mixture contains 1 % or more of TiO₂ particles with an aerodynamic diameter ≤10 μm. In addition, mixtures containing TiO₂ must be labeled with the supplemental label element ‘Hazardous respirable dust may be formed when used. Do not breathe dust’ (EUH212).

Non-classified solid mixtures must also be labeled with the EUH212 supplemental labeling element if they contain at least 1 % of TiO₂, regardless of their form, or particle size.

Liquid mixtures containing TiO₂ do not require Carc. 2 classification. However, if they contain at least 1 % of TiO₂ particles with an aerodynamic diameter ≤10 μm, then they need to be labeled with the supplemental label element ‘Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist’ (EUH211).

This guide was developed in cooperation with the German competent authority (BAuA), the European Commission and the network of national helpdesks (HelpNet), prompted by the high number of helpdesk questions coming from both industry and authorities.
