Relationships with our suppliers
Our suppliers play a key role in our Downstream business, so we manage our business relationships with them based on our General Contracting and Purchasing Terms and Conditions. These terms and conditions are intended to regulate the relationships with our suppliers, and they are part of the contractual documents for the provision of services and the performance of work.
The General Contracting and Purchasing Terms and Conditions will be applicable to all those terms that have not been expressly regulated in the Specific Terms and Conditions.
