    FAR 8.603—Purchase priorities.

    Plain-English Summary

    FAR 8.603 establishes the mandatory purchase priority order when Federal Prison Industries, Inc. (FPI) and nonprofit agencies participating in the AbilityOne Program are both capable of providing the same supplies or services. The section addresses two separate priority schemes: one for supplies and one for services, and it ties those priorities to the statutory and regulatory framework in 41 U.S.C. chapter 85 and FAR subpart 8.7. In practice, this rule tells ordering offices which source must be selected first when identical items are available from more than one mandatory source, helping agencies comply with required-source purchasing rules and avoid improper source selection. It is important because it resolves conflicts between two mandatory programs and prevents ordering offices from treating them as interchangeable without regard to the prescribed order. The rule also makes clear that commercial sources are only considered after the required priority sources, and only in the order specified for the type of requirement.

    Key Rules

    Supplies follow a fixed priority

    When identical supplies are available from both FPI and AbilityOne nonprofit agencies, ordering offices must buy in this order: first FPI, then AbilityOne nonprofit agencies, and then commercial sources. This means FPI has the highest priority for supplies.

    Services use a different priority

    For services, AbilityOne participating nonprofit agencies have first priority. If an AbilityOne source is not selected or available under the applicable rules, the ordering office may use FPI or commercial sources next.

    Applies only to identical items

    The priority rule applies when FPI and AbilityOne nonprofit agencies produce identical supplies or services. If the items are not identical, the section does not itself establish the selection order, and other FAR rules may control.

    Ordering offices must follow the sequence

    The rule is mandatory: ordering offices shall purchase in the stated priority order. Agencies do not have discretion to reverse the order based on convenience, preference, or routine buying habits.

    Commercial sources are last in line

    Commercial sources may be used only after the required priority source(s) for the applicable category have been considered. This reinforces that commercial buying is secondary to the mandatory-source structure.

    Responsibilities

    Ordering Offices

    Determine whether the requirement is for supplies or services, identify whether FPI and AbilityOne nonprofit agencies both offer identical items, and place the order using the required priority sequence in FAR 8.603.

    Contracting Officers

    Ensure purchase actions comply with the mandatory-source priority rules, document source selection when needed, and avoid awarding to a lower-priority source when a higher-priority source is available for the same requirement.

    Federal Prison Industries, Inc. (FPI)

    Provide supplies and services within its authorized scope and compete for requirements in the priority position assigned by the rule, especially for supplies.

    AbilityOne Participating Nonprofit Agencies

    Provide supplies and services within the AbilityOne Program and receive priority as specified, especially for services and second priority for supplies.

    Agency Buyers and Requisitioners

    Route requirements to the proper mandatory source and avoid bypassing the priority order when preparing requisitions or purchase requests.

    Practical Implications

    1

    This section matters most when more than one mandatory source can satisfy the same need; buyers must know whether they are procuring supplies or services before choosing a source.

    2

    A common pitfall is assuming AbilityOne and FPI are interchangeable. They are not: the priority order is different for supplies and services.

    3

    Another risk is skipping the mandatory-source check and going straight to commercial buying, which can create compliance problems and protest or audit exposure.

    4

    Contracting personnel should verify whether the requirement is truly identical across sources, because the priority rule only applies when the offerings are the same.

    5

    Good file documentation should show that the ordering office considered the required priority source first and followed the correct sequence for the type of requirement.

    Official Regulatory Text

    FPI and nonprofit agencies participating in the AbilityOne Program under 41 U.S.C. chapter 85 , Committee for Purchase from People Who Are Blind or Severely Disabled (see subpart  8.7 ) may produce identical supplies or services. When this occurs, ordering offices shall purchase supplies and services in the following priorities: (a) Supplies. (1) Federal Prison Industries, Inc. ( 41 U.S.C. 8504 ). (2) AbilityOne participating nonprofit agencies. (3) Commercial sources. (b) Services. (1) AbilityOne participating nonprofit agencies. (2) Federal Prison Industries, Inc., or commercial sources.
