As part of Rio Tinto, U.S. Borax has commercial business offices across the globe.

Our worldwide footprint allows us to respond to customers locally, when they need us most.  


Located in downtown Chicago, Illinois, this office is not only home to our North American sales and customer service teams but also our global logistics and marketing groups. Our South American sales team is located in-country, but is very much part of our unified Americas team.
