Supplier, Contractor and Vendor Vetting 

Suppliers, contractors and vendors seeking to do business with CITGO undergo a rigorous vetting process. We require that all third parties maintain the highest ethical standards and compliance in the areas of anti-corruption, safety, conflicts of interest, all CITGO policies and procedures, and all applicable national, state, and local laws and regulations. We also screen all supplier, contractor and vendor applicants against international sanctions and watch lists.
