Our history

Schumann/Steier, Inc. SSI has been servicing the Petrochemical, Base Oil and Wax market for over 25 years. Prior to 1991, Schumann/Steier, Inc. was known as Moore & Munger Lubricants, Inc., a marketer of base oils and specialties and an affiliate of Moore & Munger Marketing, Inc., one of the foremost wax marketing firms in the country. In 1989 both Moore & Munger companies were purchased by the Schumann Group of Hamburg, Germany and Arthur A. Steier.

In 1993, Schumann/Steier, Inc. was created to grow the core business of base oil and specialty marketing and diversify within the petroleum field to capitalize on Group strengths internationally as well as to embrace then future trends in synthetic fuels, ethanol and biodiesel.


In 2010 SSI acquired Chusei USA, a custom‐processing facility and the largest by product polyethylene wax USA. The chemical plant was renamed SSI Chusei, Inc. and fully operated by SSI. In 2014 SSI sold SSI Chusei to Trecora Resources for US$73 million.

In 2015 SSI invested in petroleum wells in Lousiana becoming a crude oil producer. SSI wanted to keep this business separated from our traditional trading business. SSI founded an energy company named SSI Energy to manage the wells.
