[SMM Aluminum Express News] Rio Tinto said its aluminum exports to the United States have rebounded to near pre-tariff levels, with North American shipments returning to around 80% of sales after previously falling to the mid-60% range following US import tariffs on Canadian aluminum. The recovery has been supported by elevated US aluminum premiums and tight North American supply, helping offset tariff-related costs and restore trade flows from Rio Tinto’s Quebec smelters into the US market.
