The Buy Indian Act (25 U.S.C. § 47), as amended in December 2020, states, in the pursuit of enterprise development and in general, "Unless determined by one of the Secretaries to be impracticable and unreasonable - (A) Indian labor shall be employed; and (B) purchases of Indian industry products (including printing and facilities construction, notwithstanding any other provision of law) may be made in open market by the Secretaries." Additionally, the Act requires the Secretary's respective Departments who use the procurement procedures enumerated in the Act to establish an annual minimum percentage goal for procurement.

The Department of the Interior implements the Buy Indian Act through the Department of the Interior Acquisition Regulations (DIAR). On April 8, 2022, DOI issued a final rule (87 FR 20761) that updated the regulations that implement the Buy Indian Act. The rule eliminated barriers to Indian Economic Enterprises from competing on certain construction contracts, expanded Indian Economic Enterprises' ability to subcontract construction work consistent with other socio-economic set-aside programs, and gave greater preference to Indian Economic Enterprises when a deviation from the Buy Indian Act is necessary, among other updates.
