About Us

Schaeffer Manufacturing Co. DuQuoin was founded in 1978 under the name Hicks Oils, the company originally served the lubricant needs of Southern Illinois coal mines.

As markets changed in the 80s and 90s, the company shifted its focus to include contract packaging, private label, and company branded products. This proved to be a successful move as private label packaging grew to become one of the company’s top priorities.
