Provided below are our answers to the questions most commonly asked about AOC.

  • Does having a representative in Saudi Arabia speed the approval process up?

    Not necessarily. Having a local representative in the Kingdom who can swiftly address Saudi Aramco’s requests can be of benefit. A local representative can also act as a reliable communication channel and be an asset in developing a closer relationship with Saudi Aramco.

  • How often do the priorities for materials change?

    The list of sourcing priority materials is dynamic and subject to regular update. These updates normally take place twice a year in May and October

  • Can I still apply for registration even though I don’t make any priority materials?

    Currently we only approve new sources of supply for items included on the priority list. Since this list is subject to periodic updates, your products can be potentially listed in the next update. If your company is offering products based on new or advanced technologies possibly not known to us you can contact: and we will review your offer.

  • I have just become an approved supplier. What happens next?

    When a specific requirement arises for the material you provide, you will be considered for the contract. Please be aware that Saudi Aramco has a long established preference for Saudi Arabian sources of supply, in accordance with various commercial considerations, such as price, quality, availability, marketability and transportation. Foreign-owned enterprises are also afforded adequate opportunity, in conformity with customary practices, to compete to be a supplier of materials to the company.

  • I am already an approved supplier. Can I extend my current approval range with additional commodities?

    If you would like to increase the number of commodities you supply, each item must go through the required approval process. Currently, Saudi Aramco only approves new sources of supply for items included on the priority list. Since this list is subject to periodic updates, your products can be potentially listed in the next update. If your company is offering products based on new or advanced technologies possibly not known to us you can and we will review your offer.

  • How does an inspection agency become AOC approved?

    AOC does not source inspection agencies for inclusion on the approved supplier list on an ongoing basis. The inspection agencies we use are verified as part of the bidding process for inspection contracts. Typically, these contracts have a duration of between three and five years, meaning we have a number of established contracts in place for the provision of general inspection services at any one time.

    In the final year of the established contracts, AOC will scan the market for inspection agencies capable of providing the required inspection services. The identified agencies will receive a formal request from AOC to participate in the pre-qualification process. Inspection agencies meeting the minimum requirements of pre-qualification will be invited to bid for the next contracts for general inspection services.


  • How does an inspector become AOC approved?

    Only fully qualified agency inspectors are permitted to perform any inspection activity for Saudi Aramco. All inspectors must have a minimum of six years of inspection experience in manufacturing facilities, incorporating two years of inspection experience for the specific commodity being proposed/inspected.

    Inspectors should be a high school graduate or equivalent. They must possess a working knowledge of applicable industry standards and specifications and should be able to perform inspection functions with minimal supervision. In addition, they should also possess the necessary qualifications and / or certifications relevant to the particular commodity, process or examination they will be inspecting within the fabrication process. They should also be highly proficient in speaking, reading and writing English.

    To verify that inspectors have sufficient knowledge of inspection, AOC will interview and test them for technical qualifications. In the event that an inspection agency offers up to three candidates for inspector qualification, the interview and test will be conducted in AOC’s offices or another location determined by AOC. In the case of four or more candidates, the inspection agency can propose the venue for examination.

    AOC will only qualify inspectors from an inspection agency that:

    • Holds a current contract for inspection services.
    • Is put forward for qualification by a Saudi Aramco Inspection Representative and is working on behalf of an engineering company involved in a Saudi Aramco project.

    The inspection agency must first ensure the quality of a candidate before putting them forward for qualification. When proposing inspectors for qualification, the inspection agency must provide:

    • The full name of the candidate.
    • His or her base of operation.
    • The commodities for which qualification is requested.
    • The proposed date and location of the qualification.
    • An up-to-date CV.

  • To become an approved supplier, is it mandatory to have a representative in Saudi Arabia?
