intended uses, and (iii) the manufacturer has no reason to believe that the product’s users will realize that danger. We do not purport to define the proper tort rule outside of the maritime context.
One final point for clarity: Courts have determined that this rule applies in certain related situations, including when: (i) a manufacturer directs that the part be incorporated, see, e.g., Bell v. Foster Wheeler Energy Corp., 2016 WL 5780104, *6–*7 (ED La., Oct. 4, 2016); (ii) a manufacturer itself makes the product with a part that the manufacturer knows will require replacement with a similar part, see, e.g., Chesher v. 3M Co., 234 F. Supp. 3d 693, 713–714 (S. C. 2017); Quirin, 17 F. Supp. 3d, at 769–770; May, 446 Md., at 29, 129 A. 3d, at 1000; or (iii) a product would be useless without the part, see, e.g., In re New York City Asbestos Litigation, 27 N. Y. 3d, at 793–794, 59 N. E. 3d, at 474. In all of those situations, courts have said that the product in effect requires the part in order for the integrated product to function as intended. We agree. The maritime tort rule we adopt today therefore encompasses those situations, so long as the manufacturer knows or has reason to know that the integrated product is likely to be dangerous for its intended uses, and the manufacturer has no reason to believe that the product’s users will realize that danger. *** In the maritime tort context, we hold that a product manufacturer has a duty to warn when (i) its product requires incorporation of a part, (ii) the manufacturer knows or has reason to know that the integrated product is likely to be dangerous for its intended uses, and (iii) the manufacturer has no reason to believe that the product’s users will realize that danger. The District Court should evaluate the evidence under that rule. Although we do not agree with all of the reasoning of the Third Circuit, we
