### 25.000 Scope of part.

(a) This part provides policies and procedures for—

(1) Acquisition of foreign supplies, services, and construction materials; and

(2) Contracts performed outside the United States.

(b) It implements the Buy American Act, trade agreements, and other laws and regulations.

### 25.001 General.

(a) The Buy American Act—

(1) Restricts the purchase of supplies, that are not domestic end products, for use within the United States. A foreign end product may be purchased if the contracting officer determines that the price of the lowest domestic offer is unreasonable or if another exception applies (see Subpart 25.1); and

(2) Requires, with some exceptions, the use of only domestic construction materials in contracts for construction in the United States (see Subpart 25.2).

(b) The restrictions in the Buy American Act are not applicable in acquisitions subject to certain trade agreements (see Subpart 25.4). In these acquisitions, end products and construction materials from certain countries receive nondiscriminatory treatment in evaluation with domestic offers. Generally, the dollar value of the acquisition determines which of the trade agreements applies. Exceptions to the applicability of the trade agreements are described in Subpart 25.4.

(c) The test to determine the country of origin for an end product under the Buy American Act (see the various country “end product” definitions in 25.003) is different from the test to determine the country of origin for an end product under the trade agreements, or the criteria for the report on end products manufactured outside the United States (see 25.004).

(1) The Buy American Act uses a two-part test to define a “domestic end product”or “domestic construction material” (manufactured in the United States and a formula based on cost of domestic components). The component test has been waived for acquisition of commercially available off-the-shelf items.

(2) Under the trade agreements, the test to determine country of origin is “substantial transformation” (i.e., transforming an article into a new and different article of commerce, with a name, character, or use distinct from the original article).

(3) For the reporting requirement at 25.004, the only criterion is whether the place of manufacture of an end product is in the United States or outside the United States, without regard to the origin of the components.

(4) When using funds appropriated under the American Recovery and Reinvestment Act of 2009 (Pub. L. 111-5), the definition of “domestic manufactured construction material” requires manufacture in the United States but does not include a requirement with regard to the origin of the components.

## Subpart 25.1—Buy American Act—Supplies

### 25.100 Scope of subpart.

(a) This subpart implements—

(1) The Buy American Act (41 U.S.C. 10a - 10d);

(2) Executive Order 10582, December 17, 1954; and

(3) Waiver of the component test of the Buy American Act for acquisitions of commercially available off-the-shelf (COTS) items in accordance with 41 U.S.C 431.

(b) It applies to supplies acquired for use in the United States, including supplies acquired under contracts set aside for small business concerns, if—

(1) The supply contract exceeds the micro-purchase threshold; or

(2) The supply portion of a contract for services that involves the furnishing of supplies (e.g., lease) exceeds the micro-purchase threshold.

### 25.101 General.

(a) The Buy American Act restricts the purchase of supplies that are not domestic end products. For manufactured

end products, the Buy American Act uses a two-part test to define a domestic end product.

(1) The article must be manufactured in the United States; and

(2) The cost of domestic components must exceed 50 percent of the cost of all the components. In accordance with 41 U.S.C. 431, this component test of the Buy American Act has been waived for acquisitions of COTS items (see 12.505(a)).

(b) The Buy American Act applies to small business set-asides. A manufactured product of a small business concern is a U.S.-made end product, but is not a domestic end product unless it meets the component test in paragraph (a)(2) of this section.

(c) Exceptions that allow the purchase of a foreign end product are listed at 25.103. The unreasonable cost exception is implemented through the use of an evaluation factor applied to low foreign offers that are not eligible offers. The evaluation factor is not used to provide a preference for one foreign offer over another. Evaluation procedures and examples are provided in Subpart 25.5.

### 25.102 Policy.

Except as provided in 25.103, acquire only domestic end products for public use inside the United States.

### 25.103 Exceptions.

When one of the following exceptions applies, the contracting officer may acquire a foreign end product without regard to the restrictions of the Buy American Act:

(a) Public interest. The head of the agency may make a determination that domestic preference would be inconsistent with the public interest. This exception applies when an agency has an agreement with a foreign government that provides a blanket exception to the Buy American Act.

(b) Nonavailability. The Buy American Act does not apply with respect to articles, materials, or supplies if articles, materials, or supplies of the class or kind to be acquired, either as end items or components, are not mined, produced, or manufactured in the United States in sufficient and reasonably available commercial quantities and of a satisfactory quality.

(1) Class determinations.

(i) A nonavailability determination has been made for the articles listed in 25.104. This determination does not necessarily mean that there is no domestic source for the listed items, but that domestic sources can only meet 50 percent or less of total U.S. Government and nongovernment demand.

(ii) Before acquisition of an article on the list, the procuring agency is responsible to conduct market research appropriate to the circumstances, including seeking of domestic sources. This applies to acquisition of an article as—

(A) An end product; or

(B) A significant component (valued at more than 50 percent of the value of all the components).

(iii) The determination in paragraph (b)(1)(i) of this section does not apply if the contracting officer learns at any time before the time designated for receipt of bids in sealed bidding or final offers in negotiation that an article on the list is available domestically in sufficient and reasonably available commercial quantities of a satisfactory quality to meet the requirements of the solicitation. The contracting officer must—

(A) Ensure that the appropriate Buy American Act provision and clause are included in the solicitation (see 22.1101(a), 22.1101(b), or 25.1102);

(B) Specify in the solicitation that the article is available domestically and that offerors and contractors may not treat foreign components of the same class or kind as domestic components; and

(C) Submit a copy of supporting documentation to the appropriate council identified in 1.201-1, in accordance with agency procedures, for possible removal of the article from the list.

(2) Individual determinations.

(i) The head of the contracting activity may make a determination that an article, material, or supply is not mined, produced, or manufactured in the United States in sufficient and reasonably available commercial quantities of a satisfactory quality.

(ii) If the contracting officer considers that the nonavailability of an article is likely to affect future acquisitions, the contracting officer may submit a copy of the determination and supporting documentation to the appropriate council identified in 1.201-1, in accordance with agency procedures, for possible addition to the list in 25.104.

(3) A written determination is not required if all of the following conditions are present:

(i) The acquisition was conducted through use of full and open competition.

(ii) The acquisition was synopsized in accordance with 5.201.

(iii) No offer for a domestic end product was received.

(c) Unreasonable cost. The contracting officer may determine that the cost of a domestic end product would be unreasonable, in accordance with 25.105 and Subpart 25.5.

(d) Resale. The contracting officer may purchase foreign end products specifically for commissary resale.

(e) Information technology that is a commercial item. The restriction on purchasing foreign end products does not apply to the acquisition of information technology that is a commercial item, when using fiscal year 2004 or subsequent fiscal year funds (Section 535(a) of Division F, Title V, Consolidated Appropriations Act, 2004, and similar sections in subsequent appropriations acts).

### 25.105 Determining reasonableness of cost.

(a) The contracting officer—

(1) Must use the evaluation factors in paragraph (b) of this section unless the head of the agency makes a written determination that the use of higher factors is more appropriate. If the determination applies to all agency acquisitions, the agency evaluation factors must be published in agency regulations; and

(2) Must not apply evaluation factors to offers of eligible products if the acquisition is subject to a trade agreement under Subpart 25.4.

(b) If there is a domestic offer that is not the low offer, and the restrictions of the Buy American Act apply to the low offer, the contracting officer must determine the reasonableness of the cost of the domestic offer by adding to the price of the low offer, inclusive of duty—

(1) 6 percent, if the lowest domestic offer is from a large business concern; or

(2) 12 percent, if the lowest domestic offer is from a small business concern. The contracting officer must use this factor, or another factor established in agency regulations, in small business set-asides if the low offer is from a small business concern offering the product of a small business concern that is not a domestic end product (see Subpart 19.5).

(c) The price of the domestic offer is reasonable if it does not exceed the evaluated price of the low offer after addition of the appropriate evaluation factor in accordance with paragraph (a) or (b) of this section. (See evaluation procedures at Subpart 25.5.)
