Asahi Metal Industry Co. v. Superior Court of Cal., Solano Cty.
The Supreme Court unanimously ruled that California could not make a Japanese component manufacturer defend an indemnity lawsuit there, even though the manufacturer knew some of its parts would eventually reach California inside another company's products.
The Court split over whether merely placing a product into the worldwide stream of commerce, plus awareness it might reach a state, is ever enough for that state to claim jurisdiction — but all nine justices agreed that forcing this foreign manufacturer to litigate a dispute with almost no connection to California would be unfair given the international stakes involved.
“The placement of a product into the stream of commerce, without more, is not an act of the defendant purposefully directed toward the forum State.”
States the plurality's core limit on using the stream-of-commerce theory to establish jurisdiction.
How it got here: California's Superior Court denied Asahi's motion to quash service; the California Court of Appeal ordered it quashed; the California Supreme Court reinstated jurisdiction, and Asahi sought review.
The Case in Depth
What happened
A motorcyclist was severely injured and his wife killed in a California crash allegedly caused by a defective tire. The Taiwanese tube manufacturer, sued by the victims, sought indemnification from Asahi, a Japanese company that made the tube's valve assembly and sold it to the Taiwanese company in Taiwan. The original injury claims settled, leaving only the indemnity dispute between the two foreign companies.
The question before the Court
Could California force a Japanese valve-maker to defend a lawsuit there just because it knew, in a general way, that some of its parts would end up in California through another company's products?
The Court's answer
No — the Court unanimously held that California could not force Asahi, a Japanese valve-maker, to defend an indemnity lawsuit there, even though it knew some of its parts would end up in California products. Beyond any question of minimum contacts, forcing Asahi to litigate in a foreign country's courts over a dispute between two foreign companies, arising from a sale made entirely in Taiwan, would be unreasonable and unfair.
The justices split on a separate question: whether merely knowing a product will flow into a state through the stream of commerce is ever enough, by itself, to establish the required connection to that state. Four justices said more is needed — like advertising or designing for that market — while others thought awareness plus economic benefit from sales there could be sufficient. That disagreement was not resolved by a majority.

Why it matters
Foreign and out-of-state manufacturers that sell components to other companies, without directly marketing, advertising, or doing business in a state, gained a strong argument against being sued there. The ruling makes it harder for injured consumers or companies pursuing indemnity claims to reach deep into a global supply chain and hale a distant component-maker into a local court.
What changes now
The California Supreme Court's judgment is reversed and the case is sent back for further proceedings consistent with the opinion, meaning the indemnity claim against Asahi cannot proceed in California courts. The decision is a final merits ruling, but because no single reasoning commanded five votes on the 'stream of commerce' test itself, lower courts continued to apply differing standards for when component sellers can be sued far from home.
What this does not decide
The Court did not resolve, with a majority, whether mere awareness that a product will enter a state through the stream of commerce is ever enough for jurisdiction \u2014 only four justices adopted that stricter view. It also did not decide whether Congress could authorize federal courts to base jurisdiction on nationwide contacts rather than state-specific ones.
Concurrences and dissents
Concurrence in part — Justice Brennan
Justice Brennan agreed the lawsuit was unreasonable and unfair under the fairness factors, but rejected the plurality's stricter 'purposeful direction' test for the stream of commerce. He argued that a manufacturer who knowingly and regularly benefits from a product's sale in a state has established minimum contacts there without needing extra conduct like advertising, because the risk of suit is foreseeable and the benefits are real.
Concurrence in part — Justice Stevens
Justice Stevens agreed the case should be reversed based on the unfairness analysis alone and thought it unnecessary to decide the minimum-contacts question at all. He also disputed the plurality's clean line between 'mere awareness' and 'purposeful availment,' suggesting Asahi's regular, high-volume sales over several years might well satisfy purposeful availment depending on the product's volume, value, and risk.
How the Court got there
The legal reasoning, step by step
- The Court applied the 'minimum contacts' framework from International Shoe, which asks whether a defendant has purposefully connected itself to a state such that being sued there is fair, not just foreseeable.
- A four-justice group concluded that simply placing a product into the worldwide stream of commerce, even with awareness it might reach a particular state, does not by itself count as purposefully directing conduct at that state; something more — like designing for that market or advertising there — is required.
- Separately, a broader group of justices analyzed reasonableness directly, weighing the heavy burden on a foreign defendant forced to litigate in a distant country's courts, the slight interest of a foreign plaintiff (the Taiwanese company) in suing in California, and the limited interest California had in a dispute that was really about indemnification between two foreign companies over a sale that happened in Taiwan.
- The Court also considered the international character of the dispute, noting that courts should show special caution before stretching personal jurisdiction across national borders and should weigh the interests of foreign nations and the federal government's foreign relations concerns.
- Balancing these reasonableness factors, the Court concluded that making Asahi defend itself in California would be unfair and unreasonable regardless of whether minimum contacts existed, so the exercise of jurisdiction violated due process.
