Tronox Increases Titanium Dioxide Prices in Asia-Pacific

Oklahoma City, Aug. 11, 2008 – Tronox Incorporated (NYSE: TRX, TRX.B), on behalf of its subsidiary companies, today announced that prices for all TRONOX® titanium dioxide (TiO2) grades sold in the Asia-Pacific region will increase by US$200 per tonne, effective Sept. 1, 2008, or as contracts allow. Other increases may be announced locally within the region.

This increase is in addition to all previously announced price increases for this region and is the next step toward partially offsetting the extraordinary increases in freight, energy and other input costs that the TiO2 industry has absorbed over the last two years.

Tronox has and will continue to focus on increasing the efficiency and productivity of its facilities; however, these increases are required to ensure the industry can profitably reinvest in the business to meet customers’ needs in the future.

Headquartered in Oklahoma City, Tronox is the world’s third-largest producer and marketer of titanium dioxide pigment, with an annual production capacity of 642,000 tonnes.
