Gränges’ Supplier Code of Conduct states that suppliers are to have zero tolerance for all types of bribes and corruption and for collaborating in violation of competition laws. They are also to avoid conflicts of interest, provide reasonable working conditions, promote good health and safety at their workplaces, and respect human rights, such as not accepting child labour or any form of forced labour, and to respect the environment by, for example, minimizing harmful emissions and waste.
