Rio Tinto requires all our suppliers to comply with our Supplier Code of Conduct and The Way We Work at all times...We investigated allegations relating to port drayage services provided by Cal Cartage Express and NFI Industries, including an independent on-site audit that entailed extensive interviews with independent drivers, and an external legal review to identify any potential breaches of our Supplier Code of Conduct and The Way We Work. The investigation did not identify any issues that warranted Rio Tinto’s contract with Cal Cartage Express and NFI Industries being terminated.

... As part of our regular contract renewal process, Rio Tinto undertook a competitive tender for drayage services for our Boron operations in 2019... As a result of this competitive tender process, Rio Tinto selected a new provider for our Boron-related drayage services.
