The Titanium Dioxide Industry Consortium (TDIC)

The manufacturers of Titanium Dioxide have joined efforts for their REACH compliance activities and have launched the TDIC REACH consortium.

Consortium description

The Titanium Dioxide Industry Consortium (TDIC) will manage the EU REACH registration of titanium dioxide and related manufacturing process intermediates and will liaise with registrants of key raw materials in other consortia and SIEFs.

Substances covered

The substances covered by the TDIC consortium are:

Substance CAS Number EC Number Molecular Formula Scope*
Titanium dioxide 13463-67-7 236-675-5 TiO2 Substance
Titanium tetrachloride 7550-45-0 231-441-9 TiCl4 Substance
Titanium oxide sulphate 13825-74-6 237-523-0 TiOSO4 Substance
Dichloride titanium oxide 13780-39-7 237-430-5 TiOCl2 Substance
Disodium titanate 12034-34-3 234-802-9 Na2TiO3 Intermediate >1000t/a
and substance 1-10t/a
The consortium will prepare registration dossiers for the substances indicated as a Substance or Intermediate under the definition of Article 3 EC Regulation 1907/2006. The registration dossier for the intermediates will be in accordance with Article 18 of the previously mentioned Regulation. As a consequence, all uses of the intermediate must be complying with Paragraph 4 of Article 18.


The TDIC REACH Consortium, which is managed by ReachCentrum, has been initially formed by members of the Titanium Dioxide Manufacturers Association (TDMA) which is a Sector Group of Cefic.

The TDIC consortium is open to any European and non-European companies manufacturing or importing in EU27 substances indicated above. The consortium works on registration dossiers for all substances indicated. Operational costs are shared equally among the members. For an appropriate fee the consortium will offer a Letter of Access to the registration dossiers being developed.

Classification and labelling

The Joint Submission EU REACH dossier, submitted by Venator Materials PLC (Venator ( as Lead Registrant (LR) on behalf of the TDIC consortium, has provided in its LR dossier for the various hazard classifications that may apply to TiO2 depending on the aerodynamic diameter as stipulated in the Classification, Packaging and Labeling Regulation Annex VI entry. All Uses continue to be supported by the LR dossier.
