Before becoming a Cepsa supplier, you must complete the registration and standardization process on our C2S platform. Following an analysis of your business and of the product or service that you supply we will assure that the level of risk is acceptable and you have the necessary skills to meet our requirements.

According to the scale of your activity with us and the cost of contracting you will be assigned to one of three levels of registration.

    • Basic registration. You can register on the system by filling in the registration questionnaire. If the data are correct you will become a valid supplier and be able to take part in bidding and auction processes.
    • Basic registration with documentation. If your business is of medium scale, you must provide additional information along with the questionnaire to become a valid supplier.
    • Full registration. If you are deemed to be a strategic supplier you must provide specific documentation. If this is approved you will become a standardized supplier.
