    FAR 25.401Exceptions.

    Plain-English Summary

    FAR 25.401 explains when the Buy American Act trade-agreements procedures in this subpart do not apply. It covers several categories of exempt acquisitions, including small business set-asides, certain national security and defense purchases, end products bought for resale, acquisitions from Federal Prison Industries and nonprofit agencies employing people who are blind or severely disabled, certain noncompetitive or sole-source acquisitions, and goods or services specifically excluded by individual trade agreements. It also identifies service categories that are excluded from coverage under the WTO Government Procurement Agreement (GPA) and various free trade agreements, such as military-support services overseas, certain ADP and telecommunications services, dredging, facility operation and management, research and development, transportation, utility services, and ship-related maintenance and repair. In practice, this section tells contracting personnel when they do not need to apply the trade-agreement rules in this subpart and when a procurement falls outside the agreement’s coverage because of the type of acquisition or the specific service involved. The practical significance is that it prevents misapplication of trade-agreement requirements, avoids unnecessary evaluation of foreign end products, and helps agencies use the correct acquisition framework for exempt buys.

    Key Rules

    Small business set-asides excluded

    This subpart does not apply to acquisitions set aside for small businesses. If the procurement is reserved for small business participation, the trade-agreement procedures in this subpart are not used.

    National security and defense exceptions

    Acquisitions of arms, ammunition, war materials, or purchases indispensable for national security or national defense are excluded. These buys are outside the subpart because security and defense needs can override normal trade-agreement coverage.

    Resale acquisitions excluded

    Acquisitions of end products for resale are not covered. The rule recognizes that items bought for resale are treated differently from items acquired for direct government use.

    Federal Prison Industries and nonprofit agencies

    Acquisitions from Federal Prison Industries, Inc., and from nonprofit agencies employing people who are blind or severely disabled are excluded. These purchases are governed by their own statutory and regulatory frameworks.

    Noncompetitive and sole-source buys

    Certain acquisitions not using full and open competition are excluded when the limitation on competition would prevent use of this subpart, including acquisitions authorized under FAR 6.2 or 6.3 and sole-source acquisitions justified under 13.501(a). The key point is that the trade-agreement procedures do not apply where the acquisition method itself makes them inapplicable.

    Trade-agreement-specific exclusions

    Goods and services specifically excluded under individual trade agreements are outside coverage, including exceptions negotiated by the U.S. Trade Representative for particular agencies. Agencies must check the applicable agreement and any agency supplementary regulations.

    Excluded services under WTO GPA and FTAs

    Paragraph (b) lists services excluded from the U.S. schedules under the WTO GPA and certain FTAs. These include military-support services overseas, specified ADP and telecommunications services, dredging, certain facility operation and management contracts, research and development, transportation, utility services, ship equipment maintenance and installation, and nonnuclear ship repair.

    Agreement-specific coverage varies

    The table shows that some exclusions apply only to certain agreements, not all of them. Contracting personnel must match the service category to the correct agreement before deciding whether the procurement is covered.

    Responsibilities

    Contracting Officer

    Determine whether the acquisition falls into one of the listed exceptions before applying this subpart. The contracting officer must identify the procurement type, check the applicable trade agreement or agency exception, and document why the subpart does or does not apply.

    Agency Acquisition Staff

    Apply the correct acquisition framework for exempt buys, including set-asides, prison industries, nonprofit agency sources, and noncompetitive acquisitions. They must also consult agency supplementary regulations and any USTR-negotiated exclusions.

    Contractor

    Understand that some procurements are outside the scope of this subpart and that trade-agreement preferences may not apply. Contractors should review solicitation terms carefully and not assume coverage where an exception or exclusion exists.

    Program/Requirement Officials

    Identify whether the requirement involves national security, defense, resale, or an excluded service category early in the acquisition planning process. They should provide accurate requirement descriptions so the contracting officer can determine coverage correctly.

    Trade Agreement/Policy Advisors

    Interpret the applicable WTO GPA or FTA schedule and agency-specific exclusions, and advise on whether a service or acquisition is covered. They help ensure the agency does not apply trade-agreement rules to excluded items or services.

    Practical Implications

    1

    This section is a coverage screen: before applying trade-agreement procedures, the contracting team must ask whether the acquisition fits one of the exceptions. Missing an exception can lead to using the wrong evaluation rules or unnecessarily restricting competition.

    2

    The service exclusions in paragraph (b) are highly agreement-specific, so a service may be excluded under one trade agreement but covered under another. Always match the service code and the agreement before making a coverage decision.

    3

    Noncompetitive acquisitions and sole-source buys require special attention because the limitation on competition may make the subpart inapplicable. A common pitfall is assuming all sole-source actions are automatically covered or automatically excluded without checking the cited authority.

    4

    Agency supplementary regulations matter. Some exclusions depend on USTR-negotiated exceptions for particular agencies, so contracting officers should not rely only on the FAR text.

    5

    For contractors, the practical effect is that foreign-content or trade-agreement issues may not matter in these procurements. For contracting officers, the key is to document the basis for exclusion so the file clearly shows why the subpart was not applied.
