Mr. Justice Stewart
delivered the opinion of the Court.
The Government commenced this civil antitrust action in the United States District Court for the Central District of California, contending that the appellee, American Building Maintenance Industries, had violated § 7 of the Clayton Act, 38 Stat. 731, as amended, 15 U. S. C. § 18, by acquiring the stock of J. E. Benton Management Corp., and by merging Benton Maintenance Co. into one of the appellee’s wholly owned subsidiaries. Following discovery proceedings and the submission of memoranda and affidavits by both parties, the District Court granted the appellee’s motion for summary judgment, holding that there had been no violation of § 7 of the Clayton Act. The Government brought an appeal to this Court, and we noted probable jurisdiction. 419 U. S. 1104.1
I
The appellee, American Building Maintenance Industries, is one of the largest suppliers of janitorial services in the country, with 56 branches serving more than 500 communities in the United States and Canada. It is also the single largest supplier of janitorial services in southern California (the area comprising Los Angeles, Orange, San Bernardino, Riverside, Santa Barbara, and Ventura Counties), providing approximately 10% of the sales of such services in that area.
[274]*274Both of the acquired companies, J. E. Benton Management Corp. and Benton Maintenance Co., also supplied janitorial services in Southern California.2 Together their sales constituted approximately 7% of the total janitorial sales in that area. Although both Benton companies serviced customers engaged in interstate operations, all of their janitorial and maintenance contracts with those customers were performed entirely within California. Neither of the Benton companies advertised nationally, and their use of interstate communications facilities to conduct business was negligible.3
The major expense of providing janitorial services is the cost of the labor necessary to perform the work. The Benton companies recruited the unskilled workers needed to supply janitorial services entirely from the local labor market in Southern California. The incidental equipment and supplies utilized in providing those janitorial services, except in concededly insignificant amounts, were purchased from local distributors.4
[275]*275It is unquestioned that the appellee, American Building Maintenance Industries, was and is actively engaged in interstate commerce. But oh the basis of the above facts the District Court concluded that at the time of the challenged acquisition and merger neither Benton Management Corp. nor Benton Maintenance Co. was “engaged in commerce” within the meaning of § 7 of the Clayton Act. Accordingly, the District Court held that there had been no violation of that law.
The Government’s appeal raises two questions: First, does the phrase “engaged in commerce” as used in § 7 of the Clayton Act encompass corporations engaged in intrastate activities that substantially affect interstate commerce? Second, if the language of § 7 requires proof of actual engagement in the flow of interstate commerce, were the Benton companies’ activities sufficient to satisfy that standard?
II
Section 7 of the Clayton Act, 15 U. S. C. § 18, provides in pertinent part:
“No corporation engaged in commerce shall acquire, directly or indirectly, the whole or any part of the stock or other share capital and no corporation subject to the jurisdiction of the Federal Trade Commission shall acquire the whole or any part of the assets of another corporation engaged also in commerce, where in any line of .commerce in any section of the country, the effect of such acquisition may be substantially to lessen competition, or to tend to create a monopoly.”
Under the explicit reach of § 7, therefore, not only must the acquiring corporation be “engaged in commerce,” but [276]*276the corporation or corporations whose stock or assets are acquired must be “engaged also in commerce.” 5
The distinct “in commerce” language of § 7, the Court observed earlier this Term, “appears to denote only persons or activities within the flow of interstate commerce — the practical, economic continuity in the generation of goods and services for interstate markets and their transport and distribution to the consumer. If this is so, the jurisdictional requirements of [§ 7] cannot be satisfied merely by showing that allegedly anticompetitive acquisitions and activities affect commerce.” Gulf Oil Corp. v. Copp Paving Co., 419 U. S. 186, 195. But even more unambiguous support for this construction of the narrow “in commerce” language enacted by Congress in § 7 of the Clayton Act is to be found in an earlier decision of this Court, FTC v. Bunte Bros., 312 U. S. 349.
In Bunte Bros, the Court was required to determine the scope of § 5 of the Federal Trade Commission Act, 38 Stat. 719, as amended, 15 U. S. C. § 45, which authorized the Commission to proceed only against “unfair methods of competition in commerce.” The Court squarely held that the Commission's § 5 jurisdiction was limited to unfair methods of competition occurring in the flow of interstate commerce. The contention that “in commerce” should be read as if it meant “affecting interstate commerce” was emphatically rejected: “The construction of § 5 urged by the Commission would thus give a federal agency pervasive control over myriads of local businesses in matters heretofore traditionally left to local custom or local law. . . . An inroad upon local [277]*277conditions and local standards of such far-reaching import as is involved here, ought to await a clearer mandate from Congress.” 312 U. S., at 354-355.6
The phrase “in commerce” does not, of course, necessarily have a uniform meaning whenever used by Congress. See, e. g., Kirschbaum Co. v. Walling, 316 U. S. 517, 520-521. But the Bunte Bros, construction of § 5 of the Federal Trade Commission Act is particularly relevant to a proper interpretation of the “in commerce” language in § 7 of the Clayton Act since both sections were enacted by the 63d Congress, and both were designed to deal with closely related aspects of the same problem — the protection of free and fair competition in the Nation’s marketplaces. See FTC v. Raladam Co., 283 U. S. 643, 647-648.

Section 7 of the Clayton Act, 15 U. S. C. § 18, provides in pertinent part:
“No corporation engaged in commerce shall acquire, directly or indirectly, the whole or any part of the stock or other share capital and no corporation subject to the jurisdiction of the Federal Trade Commission shall acquire the whole or any part of the assets of another corporation engaged also in commerce, where in any line of .commerce in any section of the country, the effect of such acquisition may be substantially to lessen competition, or to tend to create a monopoly.”
Under the explicit reach of § 7, therefore, not only must the acquiring corporation be “engaged in commerce,” but [276]*276the corporation or corporations whose stock or assets are acquired must be “engaged also in commerce.” 5
The distinct “in commerce” language of § 7, the Court observed earlier this Term, “appears to denote only persons or activities within the flow of interstate commerce — the practical, economic continuity in the generation of goods and services for interstate markets and their transport and distribution to the consumer. If this is so, the jurisdictional requirements of [§ 7] cannot be satisfied merely by showing that allegedly anticompetitive acquisitions and activities affect commerce.” Gulf Oil Corp. v. Copp Paving Co., 419 U. S. 186, 195. But even more unambiguous support for this construction of the narrow “in commerce” language enacted by Congress in § 7 of the Clayton Act is to be found in an earlier decision of this Court, FTC v. Bunte Bros., 312 U. S. 349.
In Bunte Bros, the Court was required to determine the scope of § 5 of the Federal Trade Commission Act, 38 Stat. 719, as amended, 15 U. S. C. § 45, which authorized the Commission to proceed only against “unfair methods of competition in commerce.” The Court squarely held that the Commission's § 5 jurisdiction was limited to unfair methods of competition occurring in the flow of interstate commerce. The contention that “in commerce” should be read as if it meant “affecting interstate commerce” was emphatically rejected: “The construction of § 5 urged by the Commission would thus give a federal agency pervasive control over myriads of local businesses in matters heretofore traditionally left to local custom or local law. . . . An inroad upon local [277]*277conditions and local standards of such far-reaching import as is involved here, ought to await a clearer mandate from Congress.” 312 U. S., at 354-355.6
The phrase “in commerce” does not, of course, necessarily have a uniform meaning whenever used by Congress. See, e. g., Kirschbaum Co. v. Walling, 316 U. S. 517, 520-521. But the Bunte Bros, construction of § 5 of the Federal Trade Commission Act is particularly relevant to a proper interpretation of the “in commerce” language in § 7 of the Clayton Act since both sections were enacted by the 63d Congress, and both were designed to deal with closely related aspects of the same problem — the protection of free and fair competition in the Nation’s marketplaces. See FTC v. Raladam Co., 283 U. S. 643, 647-648.
The Government argues, however, that despite its basic identity to § 5 of the Federal Trade Commission Act, the phrase “engaged in commerce” in § 7 of the Clayton Act should be interpreted to mean engaged in any activity that is subject to the constitutional power of Congress over interstate commerce. The legislative history of the Clayton Act, the Government contends, demonstrates that the “in commerce” language of § 7 was intended to be coextensive with the reach of congressional power under the Commerce Clause. Moreover, the argument continues, § 7 was designed to supplement the [278]*278Sherman Act and to arrest the creation of trusts or monopolies in their incipiency, United States v. E. I. du Pont de Nemours & Co., 353 U. S. 586, 589, and it would be anomalous, in light of this history and purpose, to hold that the Clayton Act’s jurisdictional scope is more restricted than that of the Sherman Act.
It is certainly true that the Court has held that in the Sherman Act, “Congress wanted to go to the utmost extent of its Constitutional power in restraining trust and monopoly agreements United States v. SouthEastern Underwriters Assn., 322 U. S. 533, 558. Accordingly, the Sherman Act has been applied to local activities which, although not themselves within the flow of interstate commerce, substantially affect interstate commerce. See, e. g., Mandeville Island Farms, Inc. v. American Crystal Sugar Co., 334 U. S. 219; United States v. Employing Plasterers Assn., 347 U. S. 186. But the Government’s argument that § 7 should likewise be read to reach intrastate corporations affecting interstate commerce is not persuasive.
Unlike § 7, with its precise “in commerce” language, § 1 of the Sherman Act, 26 Stat. 209, as amended, 15 U. S. C. § 1, prohibits every contract, combination, or conspiracy “in restraint of trade or commerce among the several States . . . .” “The jurisdictional reach of § 1 thus is keyed directly to effects on interstate markets and the interstate flow of goods.” Gulf Oil Corp. v. Copp Paving Co., 419 U. S., at 194. No similar concern for the impact of intrastate conduct on interstate commerce is evident in § 7’s “engaged in commerce” requirements.
The Government’s contention that it would be anomalous for Congress to have strengthened the antitrust laws by curing perceived deficiencies in the Sherman Act and at the same time to have limited the jurisdictional scope of those remedial provisions founders also on the express [279]*279language of § 7. Thus, although the Sherman Act proscribes every contract, combination, or conspiracy in restraint of trade or commerce, whether entered into by a natural person, partnership, corporation, or other form of business organization, § 7 of the Clayton Act is explicitly limited to corporate acquisitions. Yet it surely could not be seriously argued that this “anomaly” must be ignored, and § 7 extended to reach an allegedly anticompetitive acquisition of partnership assets.7 There is no more justification for concluding that the equally explicit “in commerce” limitation on § 7’s reach should be disregarded.
More importantly, whether or not Congress in enacting the Clayton Act in 1914 intended to exercise fully its power to regulate commerce, and whatever the understanding of the 63d Congress may have been as to the extent of its Commerce Clause power, the fact is that [280]*280when § 7 was re-enacted in 1950, the phrase “engaged in commerce” had long since become a term of art, indicating a limited assertion of federal jurisdiction. In Schechter Corp. v. United States, 295 U. S. 495, for example, the Court had drawn a sharp distinction between activities in the flow of interstate commerce and intrastate activities that affect interstate commerce. Id., at 542-544. Similarly, the Court’s opinion in NLRB v. Jones & Laughlin Steel Corp., 301 U. S. 1, two years later, had emphasized that congressional authority to regulate commerce was not limited to activities actually “in commerce,” but extended as well to conduct that substantially affected interstate commerce. And the Bunte Bros, decision in 1941 had stressed the distinction between unfair methods of competition “in commerce” and those that “affected commerce,” in limiting the scope of the Commission’s authority under the “in commerce” language of § 5 of the Federal Trade Commission Act.
Congress, as well, in the years prior to 1950 had repeatedly acknowledged its recognition of the distinction between legislation limited to activities “in commerce,” and an assertion of its full Commerce Clause power so as to cover all activity substantially affecting interstate commerce. Section 10 (a) of the National Labor Relations Act, 49 Stat. 453, as amended, 29 U. S. C. § 160 (a), for example, empowered the National Labor Relations Board to prevent any person from engaging in an unfair labor practice “affecting commerce.” Section 2 (7) of the Act, 49 Stat. 450, as amended, 29 U. S. C. § 152 (7), in turn, defined “affecting commerce” to mean “in commerce, or burdening or obstructing commerce or the free flow of commerce . . . .” Similarly, the Bituminous Coal Act of 1937, c. 127, 50 Stat. 72, providing for the fixing of prices for bituminous coal, the proscription of unfair trade practices, and the establishment of marketing procedures, [281]*281applied to sales and transactions “in or directly affecting interstate commerce in bituminous coal.” 50 Stat. 76.
In marked contrast to the broad “affecting commerce” jurisdictional language utilized in those statutes, however, Congress retained the narrower “in commerce” formulation when it amended and re-enacted § 7 of the Clayton Act in 1950. The 1950 amendments were designed in large part to “plug the loophole” that existed in § 7 as initially enacted in 1914, by expanding its coverage to include acquisitions of assets, as well as acquisitions of stock. In addition, other language in § 7 was amended to make plain the full reach of the section’s prohibitions. See Brown Shoe Co. v. United States, 370 U. S. 294, 311-323. Yet, despite the sweeping changes made to effectuate those purposes, and despite decisions of this Court, such as Bunte Bros., that had limited the reach of the phrase “in commerce” in similar regulatory legislation, Congress preserved the requirement that both the acquiring and the acquired companies be “engaged in commerce.”
This congressional action cannot be disregarded, as the Government would have it, as simply a result of congressional inattention, for Congress was fully aware in enacting the 1950 amendments that both the original and the newly amended versions of § 7 were limited to corporations “engaged in commerce.” See, e. g., H. R. Rep. No. 1191, 81st Cong., 1st Sess., 5-6. Rather, the decision to re-enact § 7 with the same “in commerce” limitation can be rationally explained only in terms of a legislative intent, at least in 1950, not to apply the rather drastic prohibitions of § 7 of the Clayton Act to the full range of corporations potentially subject to the commerce power.
Finally, the Government’s contention that a limitation of the scope of § 7 to its plain meaning would undermine [282]*282the section’s remedial purpose is belied by the past enforcement policy of the Federal Trade Commission and the Department of Justice — the two governmental agencies charged with enforcing the section’s prohibitions. Clayton Act §§ 11, 15, 15 U. S. C. §§21 (a), 25. The Federal Trade Commission has repeatedly held that § 7 applies only to an acquisition in which both the acquired and the acquiring companies are engaged directly in interstate commerce. E. g., Foremost Dairies, Inc., 60 F. T. C. 944, 1068-1069; Beatrice Foods Co., 67 F. T. C. 473, 730-731; Mississippi River Fuel Corp., 75 F. T. C. 813, 918. And while the Government explains that it has never taken a formal position that § 7 does not apply to intrastate firms affecting interstate commerce, it does concede that previous § 7 cases brought by the Department of Justice have invariably involved firms clearly engaged in the flow of interstate commerce.8 In light of this consistent enforcement practice, it is difficult to credit the argument that § 7’s remedial purpose would be frustrated by construing literally § 7’s twice-enacted “in commerce” requirement.
[283]*283In sum, neither the legislative history nor the remedial purpose of § 7 of the Clayton Act, as amended and reenacted in 1950, supports an expansion of the scope of § 7 beyond that defined by its express language. Accordingly, we hold that the phrase “engaged in commerce” as used in § 7 of the Clayton Act means engaged in the flow of interstate commerce, and was not intended to reach all corporations engaged in activities subject to the federal commerce power.
Ill
The Government alternatively argues that even if § 7 applies only to corporations engaged in the flow of interstate commerce, the Benton companies’ activities at the time of the acquisition and merger placed them in that flow. To support this contention the Government relies primarily on the fact that the Benton companies performed a substantial portion of their janitorial services for enterprises which were themselves clearly engaged in selling products in interstate and international markets and in providing interstate communication facilities.9 But simply supplying localized services to a corporation engaged in interstate commerce does not satisfy the “in commerce” requirement of § 7.
To be engaged “in commerce” within the meaning of § 7, a corporation must itself be directly engaged in the production, distribution, or acquisition of goods or services in interstate commerce. See Gulf Oil Corp. v. Copp Paving Co., 419 U. S., at 195. At the time of the acquisition and merger, however, the Benton companies were completely insulated from any direct participation [284]*284in interstate markets or the interstate flow of goods or services. The firms’ activities were limited to providing janitorial services within Southern California to corporations that made wholly independent pricing decisions concerning their own products. Consequently, whether or not their effect on interstate commerce was sufficiently substantial to come within the ambit of the constitutional power of Congress under the Commerce Clause, in providing janitorial services the Benton companies were not themselves “engaged in commerce” within the meaning of § 7. Cf. Mandeville Island Farms, Inc. v. American Crystal Sugar Co., 334 U. S., at 227-235.10
[285]*285Similarly, although the Benton companies used janitorial equipment and supplies manufactured in large part outside of California, they did not purchase them directly from suppliers located in other States. Cf. Foremost Dairies, Inc., 60 F. T. C., at 1068-1069. Rather, those products were purchased in intrastate transactions from local distributors. Once again, therefore, the Benton companies were separated from direct participation in interstate commerce by the pricing and other marketing. decisions of independent intermediaries. By the time the Benton companies purchased their janitorial supplies, the flow of commerce had ceased. See Schechter Corp. v. United States, 295 U. S., at 542-543.11
In short, since the Benton companies did not participate directly in the sale, purchase, or distribution of goods or services in interstate commerce, they were not "engaged in commerce” within the meaning of § 7 of the Clayton Act.12 The District Court, therefore, properly [286]*286concluded that the acquisition and merger in this case were not within the coverage of § 7 of the Clayton Act. The judgment of the District Court is affirmed.
It is so ordered.
