Coles requires all Branded Suppliers (Food) to be certified to an accepted third-party audit and certification programme such as BRCGS, SQF or Freshcare, appropriate to the products and operations in scope. To further protect and enhance the Coles brand, suppliers must also comply with the additional criteria defined in the Coles Supplier Requirements (CSR), which sit alongside the chosen base standard and are assessed as an integrated part of the audit process.
