U.S. BORAX PRODUCTS

High quality, high reliability, high performance.
It’s what we’re known for.

For over a century, U.S. Borax has been mining, refining, and transforming boron into products that are essential to modern living. Yet we’re anything but old fashioned. Our scientists and technical experts, in concert with industry, community, and educational leaders around the globe, continually study, develop, and support new and better ways to put boron and borates to work. Along with our parent company, Rio Tinto, we’re committed to pure, refined products; responsible, safe operations; and sustainable development.
