Recent Price History

Borate pricing is dominated by two producers: Eti Maden (Turkey) and Rio Tinto Borates (US), which together control ~75% of global supply and effectively set prices through published price lists. B2O3 equivalent pricing ranges from $500-700/tonne depending on product and grade. The duopolistic market structure means pricing is relatively stable compared to other minerals but lacks the transparency of exchange-traded commodities. Specialty products like boron carbide command significantly higher prices.
