CITGO Supplier Information

Supplier Information

Doing Business With Us

As a refining and marketing company in a very competitive industry, CITGO purchases goods and services related to manufacturing, transporting and marketing gasoline, lubricants and other petroleum-based products. As a company, we value these critical supplier relationships and work with our suppliers to provide superior products, services and superb customer service. We welcome potential business partners to learn more about our business and how to be a CITGO supplier should a business opportunity arise.


Supplier Expectations

CITGO requires that all suppliers, vendors and contractors maintain the highest standards and compliance in the areas of anti-corruption, safety, non-conflict and all CITGO policies and procedures. This is a mandatory requirement. It is also expected that all suppliers, vendors and contractors comply with all applicable national, state and local laws, rules and regulations required to conduct business. They will also be responsible for adhering to any and all contractual obligations as well as avoiding any “conflict of interest.” Suppliers must also promote a safe, secure and healthy workplace while continuously making efforts to improve the safety, security, health and environmental performance of each CITGO location.


Register as CITGO Non-Hydrocarbon Supplier

CITGO uses a global enterprise system, GEP SMART, in which suppliers must register for future considerations in the bidding process. The benefit to any potential supplier is that your business information will be readily available to authorized personnel at all CITGO operational areas to access should a future business opportunity arise. Registering as a CITGO supplier is a secure way to ensure you are considered in our competitive bidding process. This process is designed to ensure equal opportunities are given when performing our internal due diligence during our review process; however, this does not guarantee that your company or enterprise will be awarded business with CITGO.


Register as a CITGO Commercial Counterparty for Hydrocarbons

Registering as a prospective CITGO commercial counterparty allows us to perform initial screening of your organization for consideration as a supplier or customer of hydrocarbons (e.g., crude, feedstocks, refined products) and related services (e.g., transportation services, market intelligence services).  Upon successful completion of this initial screen, your candidacy will be forwarded to the CITGO business representative(s) associated with the business unit(s) with whom your organization wishes to engage.  This process ensures that viable business opportunities receive attention.


ISNetworld Registration

To be considered for doing business with CITGO, suppliers must meet CITGO standard qualification requirements, including technical, operational and safety standards. If you provide services that may impact operations in a process related area (e.g. process unit, tank farm, dock facility, loading racks, etc.), that are potentially hazardous, or that require a safe work permit, you must meet CITGO safety and insurance requirements. CITGO uses ISNetworld, a third party company to verify insurance and safety requirements for a nominal fee. You will be required to provide insurance, safety, health and security information to our authorized agent, including:

  • Standard Supplier Questionnaire
  • Insurance Certificates (e.g. General Liability, Employee Liability, Automobile Liability, Workers Compensation)
  • Occupational Safety and Health Administration (OSHA) logs for the last 3 years
  • Employee Modifier Rate (EMR) letters for the last 3 years
  • Operator Qualification Report (OQR), if applicable

CITGO Buying Group

In addition to our refining business, we offer our customers a wide range of quality products through a network of more than 4,700 independently owned and operated retail locations across the United States. All in-store merchandise and maintenance services are purchased directly by a Marketer or Dealer who owns the location. CITGO does not interact in the purchase and negotiation of these products or services for our retail outlets, nor do we provide lists of our retail outlets for this purpose. Some of our Marketers participate in the CITGO Buying Group, which is managed through C-Square . You may find further information at

If you are a small, woman, or minority owned business, we strongly encourage your business to register as a CITGO Supplier so that you may be added to our database and considered for future opportunities.
