Tata Chemicals North America Inc., hereinafter referred to as Tata Chemicals North America (TCNA), is one of the world's leading producers of high-quality soda ash. TCNA and its predecessor companies have been producing soda ash (also known as sodium carbonate) since 1884. Soda ash is a raw material used by several industries to make a range of essential products, such as glass, baking soda, laundry detergent, paper, textiles, potable water and clean air.

Formerly known as General Chemical Industrial Products Inc., TCNA became a part of Tata Chemicals Ltd. (TCL) in 2008. TCL, a part of the global Tata Group, is one of the world's leading chemicals companies, with a widespread portfolio of household products, industrial chemicals and agricultural additives. TCL has its soda ash operations in the US, UK, Kenya and India.

Headquartered in Utah, TCNA's manufacturing operations are based in Green River, Wyoming, USA. TCNA's Green River facility is one of the largest soda ash facilities in North America, with an underground trona mine that spans 55 square miles. Trona is a naturally occurring mineral ore that contains sodium carbonate compounds.

TCNA mines more than 4.5 million tonnes per year of trona ore that it processes into soda ash at its surface refining plant. The estimated recoverable trona ore reserves consist of approximately 600 million tonnes, enough to provide approximately 100 years of reserves based on current operating rates.
