12 C.F.R. § 4.63
The OCC's policy is to ensure that MWOBs and IDOBs have the opportunity to participate, to the maximum extent possible, in contracts awarded by the OCC. The OCC awards contracts consistent with the principles of full and open competition and best value acquisition, and with the concept of contracting for agency needs at the lowest practicable cost. The OCC ensures that MWOBs and IDOBs have the opportunity to participate fully in all contracting activities that the OCC enters into for goods and services, whether generated by the headquarters office in Washington, DC, or any other office of the OCC. Contracting opportunities may include small purchase awards, contracts above the small purchase threshold, and delivery orders issued against other governmental agency contracts.
