Buy Indian Act Contracting
A working reference for clinic staff and contracting officers on what the Buy Indian Act does, who qualifies, and how it applies to optical purchasing.
What the law says
The Buy Indian Act, codified at 25 U.S.C. § 47, was enacted in 1910. It authorizes federal agencies to purchase supplies, services, and construction from qualified Native-owned firms — known as Indian Economic Enterprises (IEEs) — giving preference outside the normal full-and-open competitive process.
The Transfer Act of 1954 (codified at 25 U.S.C. 1633) extended this authority specifically to the Indian Health Service, allowing IHS to use the Buy Indian Act to carry out its health care responsibilities. IHS implements the Act through its acquisition regulation at 48 CFR Part 326, Subpart 326.6.
On January 13, 2022, IHS published a final rule strengthening enforcement of Buy Indian Act preference across its procurement activity, in coordination with HHS and the Office of Management and Budget — a direct response to long-standing recommendations from Tribes and Tribal organizations.
What doesn't fall under it
The Buy Indian Act does not apply to contracts awarded under the Indian Self-Determination and Education Assistance Act (Public Law 93-638), or to purchase orders issued through the Purchased/Referred Care (PRC) program. Those follow separate authorities.
What counts as an Indian Economic Enterprise?
To qualify for Buy Indian Act preference, a business generally must be at least 51% owned and controlled by one or more enrolled members of a federally recognized Tribe, and meet the definition of an Indian Economic Enterprise under HHSAR 326.601. Vendors self-certify their status as part of a solicitation response, and that status must hold at the time of offer, at time of award, and throughout contract performance.
Why this matters for your optical purchasing decision.
Faster path to award
Buy Indian Act set-asides allow IHS to negotiate directly with qualified IEEs rather than running a full open competition, which can shorten the procurement timeline for routine optical purchases.
Compliance, not just goodwill
Under the 2022 final rule, IHS contracting offices are expected to use Buy Indian Act authority whenever practicable — documenting a sourcing decision toward a qualified IEE supports that compliance posture.
Economic impact stays local
Dollars spent with a Native-owned Indian Economic Enterprise circulate back into Tribal communities rather than leaving Indian Country entirely.
We handle the vendor-side paperwork.
Native Health Advisors self-certifies as an Indian Economic Enterprise and has completed the representations required in IHS solicitations before. When your contracting office is ready to move, we can typically turn around the required documentation quickly, so the administrative side doesn't hold up your optical program.
