tries, 452 F. Supp. 130 (MD Pa. 1978). There is no evidence that Asahi designed its product in anticipation of sales in California. Cf. Rockwell International Corp. v. Costruzioni Aeronautiche Giovanni Agusta, 553 F. Supp. 328 (ED Pa. 1982). On the basis of these facts, the exertion of personal jurisdiction over Asahi by the Superior Court of California * exceeds the limits of due process.

B

The strictures of the Due Process Clause forbid a state court to exercise personal jurisdiction over Asahi under circumstances that would offend "traditional notions of fair play and substantial justice."" International Shoe Co. v. Washington, 326 U. S., at 316, quoting Milliken v. Meyer, 311 U. S., at 463.

We have previously explained that the determination of the reasonableness of the exercise of jurisdiction in each case will depend on an evaluation of several factors. A court must consider the burden on the defendant, the interests of the forum State, and the plaintiff's interest in obtaining relief. It must also weigh in its determination "the interstate judicial system's interest in obtaining the most efficient resolution of controversies; and the shared interest of the several States in furthering fundamental substantive social policies." World-Wide Volkswagen, 444 U. S., at 292 (citations omitted).

*We have no occasion here to determine whether Congress could, consistent with the Due Process Clause of the Fifth Amendment, authorize federal court personal jurisdiction over alien defendants based on the aggregate of national contacts, rather than on the contacts between the defendant and the State in which the federal court sits. See Max Daetwyler Corp. v. R. Meyer, 762 F. 2d 290, 293–295 (CA3 1985); DeJames v. Magnificence Carriers, Inc., 654 F. 2d 280, 283 (CA3 1981); see also Born, Reflections on Judicial Jurisdiction in International Cases, to be published in 17 Ga. J. Int'l & Comp. L. 1 (1987); Lilly, Jurisdiction Over Domestic and Alien Defendants, 69 Va. L. Rev. 85, 127–145 (1983).

A consideration of these factors in the present case clearly reveals the unreasonableness of the assertion of jurisdiction over Asahi, even apart from the question of the placement of goods in the stream of commerce.

Certainly the burden on the defendant in this case is severe. Asahi has been commanded by the Supreme Court of California not only to traverse the distance between Asahi's headquarters in Japan and the Superior Court of California in and for the County of Solano, but also to submit its dispute with Cheng Shin to a foreign nation's judicial system. The unique burdens placed upon one who must defend oneself in a foreign legal system should have significant weight in assessing the reasonableness of stretching the long arm of personal jurisdiction over national borders.

When minimum contacts have been established, often the interests of the plaintiff and the forum in the exercise of jurisdiction will justify even the serious burdens placed on the alien defendant. In the present case, however, the interests of the plaintiff and the forum in California's assertion of jurisdiction over Asahi are slight. All that remains is a claim for indemnification asserted by Cheng Shin, a Tawainese corporation, against Asahi. The transaction on which the indemnification claim is based took place in Taiwan; Asahi's components were shipped from Japan to Taiwan. Cheng Shin has not demonstrated that it is more convenient for it to litigate its indemnification claim against Asahi in California rather than in Taiwan or Japan.

Because the plaintiff is not a California resident, California's legitimate interests in the dispute have considerably diminished. The Supreme Court of California argued that the State had an interest in "protecting its consumers by ensuring that foreign manufacturers comply with the state's safety standards." 39 Cal. 3d, at 49, 702 P. 2d, at 550. The State Supreme Court's definition of California's interest, however, was overly broad. The dispute between Cheng Shin and Asahi is primarily about indemnification rather than safety

standards. Moreover, it is not at all clear at this point that California law should govern the question whether a Japanese corporation should indemnify a Taiwanese corporation on the basis of a sale made in Taiwan and a shipment of goods from Japan to Taiwan. Phillips Petroleum Co. v. Shutts, 472 U. S. 797, 821-822 (1985); Allstate Insurance Co. v. Hague, 449 U. S. 302, 312-313 (1981). The possibility of being haled into a California court as a result of an accident involving Asahi's components undoubtedly creates an additional deterrent to the manufacture of unsafe components; however, similar pressures will be placed on Asahi by the purchasers of its components as long as those who use Asahi components in their final products, and sell those products in California, are subject to the application of California tort law.

In

World-Wide Volkswagen also admonished courts to take into consideration the interests of the "several States," in addition to the forum State, in the efficient judicial resolution of the dispute and the advancement of substantive policies. In the present case, this advice calls for a court to consider the procedural and substantive policies of other nations whose interests are affected by the assertion of jurisdiction by the California court. The procedural and substantive interests of other nations in a state court's assertion of jurisdiction over an alien defendant will differ from case to case. every case, however, those interests, as well as the Federal Government's interest in its foreign relations policies, will be best served by a careful inquiry into the reasonableness of the assertion of jurisdiction in the particular case, and an unwillingness to find the serious burdens on an alien defendant outweighed by minimal interests on the part of the plaintiff or the forum State. "Great care and reserve should be exercised when extending our notions of personal jurisdiction into the international field." United States v. First National City Bank, 379 U. S. 378, 404 (1965) (Harlan, J., dissenting). See Born, Reflections on Judicial Jurisdiction in International Cases, to be published in 17 Ga. J. Int'l & Comp. L. 1 (1987).

Opinion of BRENNAN, J.

480 U.S.

Considering the international context, the heavy burden on the alien defendant, and the slight interests of the plaintiff and the forum State, the exercise of personal jurisdiction by a California court over Asahi in this instance would be unreasonable and unfair.

III

Because the facts of this case do not establish minimum contacts such that the exercise of personal jurisdiction is consistent with fair play and substantial justice, the judgment of the Supreme Court of California is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.

It is so ordered.

JUSTICE BRENNAN, with whom JUSTICE WHITE, JUSTICE MARSHALL, and JUSTICE BLACKMUN join, concurring in part and concurring in the judgment.

I do not agree with the interpretation in Part II-A of the stream-of-commerce theory, nor with the conclusion that Asahi did not "purposely avail itself of the California market." Ante, at 112. I do agree, however, with the Court's conclusion in Part II-B that the exercise of personal jurisdiction over Asahi in this case would not comport with "fair play and substantial justice," International Shoe Co. v. Washington, 326 U. S. 310, 320 (1945). This is one of those rare cases in which "minimum requirements inherent in the concept of 'fair play and substantial justice' . . . defeat the reasonableness of jurisdiction even [though] the defendant has purposefully engaged in forum activities." Burger King Corp. v. Rudzewicz, 471 U. S. 462, 477-478 (1985). I therefore join Parts I and II-B of the Court's opinion, and write separately to explain my disagreement with Part II–A.

Part II-A states that "a defendant's awareness that the stream of commerce may or will sweep the product into the forum State does not convert the mere act of placing the product into the stream into an act purposefully directed to

ward the forum State." Ante, at 112. Under this view, a plaintiff would be required to show "[a]dditional conduct" directed toward the forum before finding the exercise of jurisdiction over the defendant to be consistent with the Due Process Clause. Ibid. I see no need for such a showing, however. The stream of commerce refers not to unpredictable currents or eddies, but to the regular and anticipated flow of products from manufacture to distribution to retail sale. As long as a participant in this process is aware that the final product is being marketed in the forum State, the possibility of a lawsuit there cannot come as a surprise. Nor will the litigation present a burden for which there is no corresponding benefit. A defendant who has placed goods in the stream of commerce benefits economically from the retail sale of the final product in the forum State, and indirectly benefits from the State's laws that regulate and facilitate commercial activity. These benefits accrue regardless of whether that participant directly conducts business in the forum State, or engages in additional conduct directed toward that State. Accordingly, most courts and commentators have found that jurisdiction premised on the placement of a product into the stream of commerce is consistent with the Due Process Clause, and have not required a showing of additional conduct.'
