    FAR 12.500Scope of subpart.

    Plain-English Summary

    FAR 12.500 is the scope statement for Subpart 12.5, and it explains what the subpart is for and what kinds of legal provisions it covers. Specifically, it identifies the laws that do not apply to contracts for commercial products, contracts for commercial services, subcontracts at any tier for commercial products or commercial services, and contracts and subcontracts at any tier for commercially available off-the-shelf (COTS) items. It also covers laws that Congress has amended so they apply differently, or not at all, to commercial product and commercial service acquisitions. In practice, this section tells contracting officers and contractors that commercial-item buying is governed by a special statutory framework under 41 U.S.C. 1906 and 1907, which is intended to reduce unnecessary government-unique requirements and make federal procurement more consistent with commercial market practices. The practical significance is that users must look to Subpart 12.5 to determine which statutes are waived, modified, or still applicable before inserting clauses, evaluating compliance obligations, or flowing requirements down to subcontractors.

    Key Rules

    Lists inapplicable statutes

    Subpart 12.5 identifies provisions of law that do not apply to acquisitions of commercial products or commercial services. This means the normal default assumption for many government-specific statutes does not carry over to commercial buying unless the statute is specifically preserved or modified.

    Applies to all subcontract tiers

    The scope extends to subcontracts at any tier for commercial products or commercial services. Contractors must therefore consider these statutory exceptions not only in prime contracts, but also when managing commercial-item subcontracting relationships.

    COTS receives the same treatment

    The subpart also covers contracts and subcontracts at any tier for COTS items. COTS acquisitions are treated within the commercial-item framework, so the same statutory exclusions and modifications apply unless a specific law says otherwise.

    Captures modified statutes too

    Subpart 12.5 does not only list laws that are completely inapplicable; it also lists laws that have been amended to change how they apply to commercial acquisitions. Users must read the specific statute and FAR implementation to understand the exact obligation.

    Statutory basis controls

    This scope is grounded in 41 U.S.C. 1906 and 1907. The subpart exists to implement those statutory directives, so the FAR text is a guide to congressional exceptions and modifications rather than a general policy preference.

    Responsibilities

    Contracting Officer

    Determine whether the acquisition is for commercial products, commercial services, or COTS items, then consult Subpart 12.5 to identify which statutes are inapplicable or modified before drafting the solicitation and contract.

    Contractor

    Understand which statutory requirements do not apply to the commercial-item contract and ensure compliance with any remaining applicable requirements, including any flowed-down obligations to commercial-item subcontractors.

    Subcontractor

    Review flowed-down requirements in light of the commercial-item framework and recognize that some statutes may not apply at lower tiers, while others may still be imposed by contract or by applicable law.

    Agency

    Apply the statutory commercial-item framework consistently and avoid imposing government-unique requirements that Subpart 12.5 removes or modifies for commercial acquisitions.

    Practical Implications

    1

    This section is a screening tool: before adding clauses or compliance requirements, users must check whether the acquisition is commercial or COTS and then verify whether the underlying statute is excluded or modified.

    2

    A common pitfall is assuming that because a contract is commercial, all government requirements disappear; in reality, only the statutes listed in Subpart 12.5 are affected, and some are only modified rather than removed.

    3

    Another frequent mistake is forgetting that the scope reaches subcontracts at any tier, which matters when commercial primes manage supplier flowdowns.

    4

    Contracting officers should use this section early in acquisition planning to avoid drafting solicitations that include inapplicable clauses or evaluation factors.

    5

    Contractors should use it to challenge or clarify requirements that appear inconsistent with the commercial-item statutory framework, especially where a clause seems to impose a law that Subpart 12.5 says does not apply.
