# Mosaic suspends phosphate mines in Brazil after new dam rules | World Fertilizer

> Mosaic said it will suspend production at its Tapira and Catalão phosphate mines in Brazil after Brazil's National Mining Agency refused a deadline extension for stability certification on three tailings dams. The rules followed a deadly dam failure in January involving Vale. Mosaic plans to supply Brazilian customers from Tampa and Peru.
