Oklahoma is also known as the Sooner State and became the 46th state to enter the union in 1907. The economy has historically been dependent on agriculture and oil production. Livestock, wheat, dairy, cotton, soybeans, and other crops dominate a lot of their exports. Although manufacturing is a minority of the overall GDP for the state, Oklahoma has some great industrial builders in machinery and transportation equipment, among other industries. Below are all the companies in our directory that are made in Oklahoma. Have a company in mind that isn’t in our directory? Let us know!
