Tronox Holdings plc (NYSE: TROX)

Tronox is the world’s leading vertically integrated manufacturer of titanium dioxide pigment. The company extracts titanium bearing mineral sands from operations in South Africa and Australia, then beneficiates and smelts the material to produce feedstock such as titanium slag and synthetic rutile. These feedstocks are processed into TiO2 pigment at seven plants located in the United States, Australia, Brazil, the United Kingdom, France and Saudi Arabia. In addition to pigment, the extraction process yields co products including zircon, high purity pig iron and monazite. Tronox reports an annual titanium feedstock capacity of approximately 832,000 metric tons, composed of 182,000 metric tons of rutile and leucoxene, 240,000 metric tons of synthetic rutile and 410,000 metric tons of titanium slag. The firm also has the capability to produce about 297,000 metric tons of zircon and 250,000 metric tons of pig iron each year. This integrated model allows Tronox to manage the supply chain from mine to market while maintaining control over costs and quality.

Revenue is generated primarily from the sale of TiO2 pigment, zircon, high purity pig iron, monazite and titanium tetrachloride. In 2025, TiO2 sales contributed $2.3 billion to total revenue. Zircon sales amounted to $274 million in the same year. The combined sales of high purity pig iron, monazite, titanium tetrachloride and other products totaled $326 million. The company serves roughly 1,200 customers worldwide for its TiO2 pigment alone. Additional customers exist for zircon in the ceramics and foundry sectors, for high purity pig iron in automotive component manufacturing, and for monazite and titanium tetrachloride in chemical and rare earth processing.

Tronox holds a leading position in the global TiO2 market as the most vertically integrated producer, which gives it cost advantages over rivals that depend on external feedstock. Its main competitors include Chemours, LB Group, Kronos Worldwide Inc. and INEOS, as well as various regional producers in Europe and China. The company's integrated mining and smelting operations secure a reliable supply of high grade feedstock, supporting consistent product quality and competitive pricing. Tronox invests in research and development to improve process efficiency, lower emissions and develop new products such as ultrafine TiO2 for emission control applications. The firm’s extensive patent portfolio and proprietary technology in chloride and sulfate processes further strengthen its competitive stance. By controlling both raw material sources and pigment production, Tronox can respond quickly to changes in demand and maintain stable margins.

Tronox's customer base comprises approximately 1,200 TiO2 purchasers located in about 120 countries, including major paint manufacturers, plastics producers and paper mills. Zircon is sold to ceramic glazing companies, foundry operators and manufacturers of refractory materials. High purity pig iron is supplied to automotive parts makers for use in engine blocks, brake components and steering parts. Monazite is processed by rare earth companies to produce oxides needed for permanent magnets in electric vehicles and wind turbines. Titanium tetrachloride is sold to chemical producers for use in catalyst manufacturing and to a joint venture that feeds a titanium sponge plant. The company notes that its top ten TiO2 customers have received product supplies for more than ten years, reflecting long term relationships.
