Tessenderlo Kerley, Inc.

Founded in 1947, Tessenderlo Kerley, Inc. serves the agriculture, mining and industrial markets with a broad range of products and technologies around the world. The TKI family, comprised of 500 motivated individuals, is headquartered in Phoenix, Arizona, and is spread across more than 27 states. TKI is part of Belgium-based Tessenderlo Group that focuses on agriculture, valorizing bio-residuals, and providing industrial solutions. The group employs about 4,900 people globally and is a leader in most of its markets.

In 1947, The Kerley Chemical Company was founded. Today we know it as Tessenderlo Kerley Inc., a member of the Tessenderlo Group of companies. From its inception in El Paso, Texas, TKI has been at the leading edge of innovation and product development, transforming by-products into high performance products, serving the agricultural, mining, refining and industrial markets. We ‘make every molecule count.’ Our deep expertize in all aspects of sulfur chemistry and sulfur processing is at the root of the products and solutions we provide.

For more than 70 years, TKI has been committed to providing customers with the products they need to feed a growing world population, as well as key chemical processes and products used in many other industries and applications.

TKI values are fundamental to our past growth and future success. Amongst those values, a commitment to continuously improving Health and Safety has been the highest priority. Many of our locations have operated for decades without a Lost Time Incident. An achievement every past and current employee at TKI is rightly proud of. Our ongoing commitment to the ‘4R’s’ program of The Fertilizer Institute continues our history of responsible care in our industry.

As a family, we strive to reach operational and safety excellence. Our long-standing safety and sustainable culture has allowed most of our production facilities to operate for more than 20 years without a single lost time incident. At TKI, safety is our number one priority.

Together, we provide our customers and their customers, with the best in-class service while educating them on the most efficient and safe usage of our products. We also aim to create partnerships that inspire individual, team and company growth. TKI is more than just a workplace, it is an organization embedded with lasting connections and purpose.

Giving back and supporting non-profit causes in communities we serve will always be an important part of the way we do business.

As an organization, TKI supports industry-specific initiatives like the Nutrients for Life program sponsored by The Fertilizer Institute. Our contributions have made it possible for Future Farmers of America chapters in schools throughout Arizona to receive cash awards for entering statewide contests that demonstrate the value of fertilizers in growing nutritious foods.

We also contribute our time and financial contributions to causes that make a difference for our neighbors and friends in the many individual local communities where we operate our offices, manufacturing plants and production facilities.
