The Buy American Act: Requiring Government Procurements from Domestic Sources 
 
Summary 
The Buy American Act is the major domestic preference statute governing procurement by the 
federal government. Essentially it attempts to protect domestic labor by providing a preference 
for American goods in government purchases. It was enacted in 1933 and has only been 
substantively amended four times in the succeeding years. In determining what are American 
goods, the place of mining, production, or manufacture is controlling. The nationality of the 
contractor is not considered when determining if a product is of domestic origin. 
In the 110th Congress a new reporting requirement was added to the Buy American Act. Under 
P.L. 110-28, the head of each federal agency is required to annually report to Congress 
concerning procurements from non-domestic sources.  
There have been no amendments to the Buy American Act introduced in the 111th Congress. The 
American Recovery and Reinvestment Act (“The Stimulus Plan”) did not amend the Buy 
American Act. It did, however, include a provision attaching domestic content considerations to 
the funds disbursed under the Plan.

The Buy American Act: Requiring Government Procurements from Domestic Sources 
 
he Buy American Act1 is the major domestic preference statute governing procurement by 
the federal government.2 Essentially, it attempts to protect domestic labor by providing a 
T preference for American goods in government purchases. It was enacted in 19333 and has 
only been substantively amended four times in the succeeding years.4 In determining what are 
American goods, the place of mining, production, or manufacture is controlling. The nationality 
of the contractor is not considered when determining if a product is of domestic origin.5 
While the act appears to control most procurements of the federal government, it should be noted, 
when considering a particular procurement, that the application of the act may be controlled by 
other legislation or international agreement. For example, the Trade Agreements Act of 19796 
authorizes the President to waive any otherwise applicable “law, regulation or procedure 
regarding Government procurement” that would accord foreign products less favorable treatment 
than that given to domestic products.7 Article 1004 of The North American Free Trade Agreement 
(between the United States, Mexico, and Canada) disallows domestic protection legislation, such 
as the Buy-American Act, in government procurement. Other treaties and agreements also place 
limitations on the application of the act and must be considered when looking at any Buy 
American question. 
Coverage of the Buy American Act 
The domestic preference requirement of the act is quite broad in its scope. The federal 
government is required to buy domestic “articles, materials, and supplies” when they are acquired 
for public use unless a specific exemption8 applies.9 
The act applies to all federal procurements, but has separate provisions for supply contracts10 and 
construction contracts.11 Most of the rules and definitions used in applying the act are found in the                                                              
1 41 U.S.C. §§ 10a through 10d. 
2 There are numerous “little Buy American” provisions which generally govern specific types of procurements that are 
for some reason exempt from the Buy American Act, usually because the procurement is for articles for use outside of 
the United States. These provisions are beyond the scope of this paper, but should be considered when researching 
whether or not a domestic preference affects a particular procurement. These provisions are often attached to the 
appropriations acts for the agencies making the procurement in question. The most well known of these Acts is 
commonly referred to as the “Berry Amendment” and applies to certain procurements of the Department of Defense, 
see, CRS Report RL31236, 
The Berry Amendment: Requiring Defense Procurement to Come from Domestic Sources, 
by Valerie Bailey Grasso. The American Recovery and Reinvestment Act of 2009 (“The Stimulus Plan”) contains a 
“little Buy American” provision governing contracts entered into by entities utilizing federal funds received under the 
act. P.L. 111-5, § 1605,    Stat.

Federal Acquisition Regulation part 25, not in the act itself. The rules for determining whether 
products are of foreign or domestic origin are the same for both types of procurements, but 
different terminology is used and the step in the manufacturing or construction process at which 
the test is applied is different.12 The test of origin is applied to supplies delivered to the 
government.13 In contrast, under construction contracts, the test is applied to articles, materials, 
and supplies used by the contractor and subcontractors in constructing, altering, or repairing the 
building or work.14 In the case of supply contracts the test is applied to “end products.”15 
Construction contracts are concerned with the origin of “construction materials.”16 
The act differentiates between manufactured and un-manufactured articles. An un-manufactured 
article will be deemed a domestic end product or construction material if it has been mined or 
produced in the United States.17 Manufactured articles are considered domestic if they have been 
manufactured in the United States from components, “substantially all” of which have been 
mined, produced, or manufactured in the United States.18 “Substantially all” means that the cost 
of foreign components does not exceed 50% of the cost of all components.19 
Exceptions to the Buy American Act 
There are five primary exceptions to the Buy American Act. The act does not apply to 
procurements to which application would be inconsistent with the public interest or unreasonable 
in cost.20 The act does not apply to procurements of products for use outside the United States or 
of products not produced or manufactured in the United States in sufficient and reasonably 
available commercial quantities and of satisfactory quality.21 Lastly, the act does not apply to 
procurements under $2,500.22 
Inconsistent with the public interest 
The head of the procuring agency may waive the requirements of the act if a determination is 
made that the application of the act would be inconsistent with the public interest. This public 
interest exception has often been used like a national security exception by the Department of

Defense,23 but is also available for non-defense purposes. This exception places considerable 
discretion in the head of the agency. For example, this exception has been invoked after bids have 
been opened.24 
Unreasonable in cost 
A federal agency is permitted to use a foreign product if the head of the agency determines that 
the cost of the lowest priced domestic product is “unreasonable.”25 A system of price differentials 
has been established for use in making this determination.26 The general differential, applicable to 
most federal contracts, is 6%. A 12% differential is used if the contract involves a small business 
or labor surplus area. A 50% differential is applied to Department of Defense procurements.27 
The differential is added to the lowest acceptable foreign offer and then compared to the domestic 
offer. The differential is applied only to the bid price for material to be delivered under the 
contact, not the total contract price.28 Generally the differential is applied on an item by item 
basis, but a solicitation may provide that, for purposes of the act, certain items will be lumped 
together.29 
Use outside of the United States 
The act exempts articles purchased “for use outside of the United States.”30 This exception is not 
limited to only the country of use, but to products of any origin.31 For example, the exemption has 
applied to purchase of Canadian made steel towers for use in West Germany for a 
communications system procured by the U.S. military.32  
Not produced or manufactured in the United States in sufficient 
and reasonably available commercial quantities and of satisfactory 
quality 
The act exempts articles not produced or manufactured in the United States in sufficient and 
reasonably available commercial quantities and of satisfactory quality.33 The FAR provides a list

of articles which come under this exemption.34 If an agency makes a determination that an article 
not on the list is eligible for this exception, the agency must document this determination and 
submit the documentation to the appropriate FAR Council.35 
Micro Purchase Threshold 
The Buy American Act is not applicable to procurements under $2,500 according to the Federal 
Acquisitions Act of 1994.36 
Amendments to the Buy American Act 
There have been four substantive amendments to the Buy American Act in its long history. The 
first such amendment was the Buy American Act of 1988, enacted as part of the Trade and 
Competitiveness Act of 1988.37 The act’s general purpose was to prohibit federal procurement 
from countries that discriminate against the United States in their procurement practices.38 The 
1988 Act, by its terms, was to expire if not specifically extended by Congress. Congress did not 
extend this act, and it expired on April 30, 1996. 
The 1988 Act did contain one general amendment which applied to the Buy American Act as a 
whole (i.e., it was not just limited to the prohibition on procurement from discriminating 
countries). This amendment provided a definition for the Buy American Act of the term “federal 
agency.”39 Because Congress placed this definition in the 1988 Act following the expiration 
provision, one could argue that Congress did not intend for this provision to expire with the rest 
of the amendments. However, due to the unequivocal nature of the expiration language of the 
statute, the stronger argument appears to be that the definition lapsed as well, and that there is no 
definition of “federal agency” in the current Buy American Act.40 
The second substantive amendment to the Buy American Act added the micro purchase threshold 
exception to the act.41 Under this exception the act does not apply to purchases under $2,500. 
                                                             
(...continued) 
impractical. See 41 U.S.C. § 10b. See also 48 C.F.R. § 25.202(a)(1). Neither the act or the regulations give any 
guidance as to the definition of this term. The regulations do require that if any of the exceptions are used, the excepted 
materials must be listed in the contract and a written finding must be produced and be available for public inspection. 
See FAR. § 25.202(b). We were unable to find any case which discussed this term in the context of the Buy American 
Act. It should be noted that this is a separate exception from the one provided for situations where the material is 
unavailable. Therefore, one might conclude that impractical is different from unavailable.

The Buy American Act: Requiring Government Procurements from Domestic Sources 
 
The third amendment to the Buy American Act was contained in the National Defense 
Authorization Act for Fiscal Year 1997.42 It requires the Secretary of Defense to submit a report to 
Congress detailing the amount of purchases from foreign entities each year. The report must 
contain the dollar value of items for which the act was waived in that year. 
The 110th Congress extended, for FY2007 to FY2011, the requirement of annual reporting of 
purchases from foreign sources to all federal agencies.43 These reports must include the total 
dollar value of procured non-domestic articles, an itemized list of all waivers of the Buy 
American Act with a citation to the authority for the waiver, citation of the specific exemption 
utilized, and a summary of all the agency’s procurements. 
Current Legislation 
There have been no amendments to the Buy American Act introduced in the 111th Congress. The 
American Recovery and Reinvestment Act44 (“The Stimulus Plan”) did not amend the Buy 
American Act. It did, however, include a provision attaching domestic content considerations to 
the funds disbursed under the Plan. Section 1605 of the Plan provided 
Sec. 1605. Use of American Iron, Steel, and Manufactured Goods. (a) None of the funds 
appropriated or otherwise made available by this Act may be used for a project for the 
construction, alteration, maintenance, or repair of a public building or public work unless all 
of the iron, steel, and manufactured goods used in the project are produced in the United 
States. 
(b) Subsection (a) shall not apply in any case or category of cases in which the head of the 
Federal department or agency involved finds that— 
(1) applying subsection (a) would be inconsistent with the public interest; 
(2) iron, steel, and the relevant manufactured goods are not produced in the United States in 
sufficient and reasonably available quantities and of a satisfactory quality; or 
(3) inclusion of iron, steel, and manufactured goods produced in the United States will 
increase the cost of the overall project by more than 25 percent. 
(c) If the head of a Federal department or agency determines that it is necessary to waive the 
application of subsection (a) based on a finding under subsection (b), the head of the 
department or agency shall publish in the Federal Register a detailed written justification as 
to why the provision is being waived. 
(d) This section shall be applied in a manner consistent with United States obligations under 
international agreements.
