The question here is whether petitioner’s complaint stated a claim upon which relief could be granted. Petitioner is engaged аt Lombard, Illinois, in the manufacture and sale in interstate commerce of a ceramic gas burner, known as the “Radiant Burner,” for the hеating of houses and other buildings. Claiming that American Gas Association, Inc. (AGA), a membership corporation doing business in the Northern District of Illinоis and in other States, and 10 of its numerous members 1 who also are doing business in the Northern District of Illinois, combined and conspired to restrain interstate commerce in the manufacture, sale and use of gas burners in violation of § 1 of the Sherman Act, petitioner brought this action against those parties for treble damages and an injunction in the United States District Court for the Northern District of Illinois. 2
*658 The complaint included the following allegations: American Gas Association operates testing laboratories wherein it purports to determine the safety, utility and durability of gas burners. It has adopted a “seal of approval” which it affixes on such gas burners as it determines have passed its tests. Its tests are not based on “objective standards,” but are influenced by respondents, some of whom are in competition with petitioner, and thus its determinations can be made “arbitrarily and capriciously.” Petitioner has twice submitted its Radiant Burner to AGA for approval but it has not been approved, although it is safer and more efficient than, and just as durable as, gas burners which AGA has approved. “[B]ecause AGA and its Utility members, including Peoples and Northern, effectuate the plan and purpose of the unlawful combinatiоn and conspiracy alleged herein by . . . refusing to provide gas for use in the plaintiff’s Radiant Burner [s] . . . which are not approved by AGA,” petitioner’s gas burners have been effectively excluded from the market, as its potential customers will not buy gas burners for which they cannot obtain gas, and in consequence petitioner has suffered and is suffering the loss of substantial profits.
Respondents moved to dismiss for failurе of the complaint to state a claim upon which relief could be granted. The District Court granted the motions, dismissed the

complаint and entered judgment for respondents. The Court of Appeals for the Seventh Circuit affirmed.
We think the decision of the Court of Appeals does not accord with our recent decision in
Klor’s, Inc.,
v.
Broadway-Hale Stores,
By § 1, Congress has made illegal: “Every contract, сombination ... or conspiracy, in restraint of trade or commerce among the several States . . . .”
Standard Oil Co.
v.
United States,
