Opinion for the Court filed by Circuit Judge GARLAND.

Ear candles are hollow tubes made of fabric soaked in beeswax or paraffin; a user places one end in his ear and sets the other on fire with an open flame. The appellants are manufacturers, distributors, and users of ear candles, along with organizations that advocate the use of holistic health remedies like ear candles. Their lawsuit challenges warning letters the Food and Drug Administration (FDA) issued to several of the appellant manufacturers, advising that the agency considered their candles to be adulterated and misbranded medical devices. The district court dismissed the appellants’ complaint on the ground, among others, that the warning letters did not constitute “final agency action” subject to judicial review under the Administrative Procedure Act.[*942] We agree and affirm the dismissal of the complaint.

I

In February 2010, FDA issued “Warning Letters” to fifteen manufacturers and distributors of ear candles, including several of the appellants. A typical warning letter advised the recipient that FDA considered its candles to be adulterated and misbranded medical devices because “[biased on the labeling ..., it appears your ear candles are intended to mitigate or treat allergies, headaches, colds, flu, sinus congestion, sore throat, ear infections” and a variety of other medical disorders, yet “you have not obtained marketing approval or clearance before you began offering your product for sale.” Letter from FDA to Harmony Cone (Feb. 17, 2010) (J.A. 42-43) [hereinafter FDA Warning Letter]; see Letter from FDA to King Cone Int’l (Feb. 17, 2010) (J.A. 45) (stating that the manufacturer’s website contains claims that the “device is intended to relieve,” inter alia, “vision disorders® ... depression, and attention deficit disorder”); see also J.A. 47, 49 (warning letters to other manufacturers). ^[1] FDA further noted that it “has received medical device reports consistent with the danger to health posed by your device[s,] ... including reports involving ruptured tympanic membranes and burns.” FDA Warning Letter (J.A. 43). The letters advised the appellants to “take prompt action to correct [the identified] deviations” from the Food, Drug, and Cosmetic Act (FDCA). Id. (citing, inter alia, 21 U.S.C. §§ 321(h), 351(f)(1)(B), 352(a), 362(f)(1), 352®). They also “requested]” that the appellants cease marketing, promoting, and distributing ear candles and “correct the problem,” and warned that “[fjailure to promptly correct these deviations may result in regulatory action.” Id.

On March 26, 2010, after receiving such a letter, representatives of one of the appellant companies met with FDA officials. According to the appellants, at the meeting an FDA agent reiterated the agency’s position that ear candles are medical devices, and the then-Deputy Director for Regulatory Affairs asserted that FDA did not intend to approve ear candles for use in the market. See Certification in Support of Compl. ¶¶ 4-5. Even so, the Deputy Director concluded the meeting by telling the representatives that “we look forward to your response® ... and we will evaluate that response and make decisions on what we are going to do, going forward.” Id. ¶ 4. The company never responded and never submitted the information required to seek approval or clearance for its ear candles.

Instead, the appellants filed this lawsuit. Their complaint alleges, among other things, that FDA’s warning letters, coupled with the statements made by FDA officials during the March 2010 meeting, are contrary to the FDCA and violate the First Amendment. ^[2] “Plaintiffs have a right to bring this action pursuant to the Administrative Procedure! ] Act,” the complaint states, “because ... FDA [has] engaged in final agency actions that ‘are contrary to law.’ ” Compl. ¶ 10.

The district court dismissed the appellants’ suit on several grounds, including that the appellants lack standing and that the warning letters do not constitute final agency action. Holistic Candlers & [*943] Consumer Ass’n v. FDA, 770 F.Supp.2d 156, 160-62 (D.D.C.2011). Because standing is a “threshold jurisdictional question,” we must address it first. Byrd v. EPA, 174 F.3d 239, 243 (D.C.Cir.1999). FDA argues that the appellants lack standing because the letters “do not impose any requirements on the recipients,” FDA Br. 14, and hence have not caused them the “injury in fact” required to establish standing, id. at 17. See Bennett v. Spear, 520 U.S. 154, 167, 117 S.Ct. 1154, 137 L.Ed.2d 281 (1997). “In analyzing whether [a plaintiff] has standing at the dismissal stage,” however, “we must assume that [the plaintiff] states a valid legal claim and ‘must accept the factual allegations in the complaint as true.’ ” Info. Handling Servs., Inc. v. Def. Automated Printing Servs., 338 F.3d 1024, 1029 (D.C.Cir.2003) (internal citation omitted). The appellants here claim that the warning letters announce “FDA’s determination that ear candles are, per se, unapproved Medical Devices and cannot be sold in the United States,” Compl. ¶ 17, which “effectively outlaw[s] the manufacture” of ear candles, id. ¶ 3. If the appellants are right that FDA’s actions outlaw the manufacture of ear candles, there is no doubt that the appellants that manufacture such devices have suffered the requisite “injury in fact.” See Bennett, 520 U.S. at 167-68, 117 S.Ct. 1154. ^[3]

Although the appellants have standing, we conclude that they cannot satisfy another requirement for maintaining this suit: a cause of action. The appellants’ claims all rely upon the Administrative Procedure Act (APA), 5 U.S.C. §§ 701 et seq., to provide a cause of action. Compl. ¶ 10; see Trudeau v. FTC, 456 F.3d 178, 185 (D.C.Cir.2006). The APA, however, only provides a right to judicial review of “final agency action for which there is no other adequate remedy in a court.” 5 U.S.C. § 704 (emphasis added); see Trudeau, 456 F.3d at 185 (“ ‘If there was no final agency action ..., there is no doubt that appellant would lack a cause of action under the APA.’ ” (quoting Reliable Automatic Sprinkler Co. v. Consumer Prod. Safety Comm’n, 324 F.3d 726, 731 (D.C.Cir.2003))). “As a general matter, two conditions must be satisfied for agency action to be ‘final’: First, the action must mark the consummation of the agency’s decisionmaking process — it must not be of a merely tentative or interlocutory nature. And second, the action must be one by which rights or obligations have been determined, or from which legal consequences will flow.” Bennett, 520 U.S. at 177-78, 117 S.Ct. 1154 (internal citations and quotation marks omitted); see AT & T Co. v. EEOC, 270 F.3d 973, 975 (D.C.Cir.2001). FDA’s warning letters fail to satisfy either condition: they neither mark the consummation of the agency’s decision-making process nor determine the appellants’ legal rights or obligations. ^[4]

[*944] The letters plainly do not mark the consummation of FDA’s decisionmaking. The FDA Regulatory Procedures Manual describes FDA warning letters as giving “firms an opportunity to take voluntary and prompt corrective action before it initiates an enforcement action.” FDA Manual, § 4-1-1 (emphasis added). The Manual states that the violations for which warning letters are issued “may lead to enforcement action if not promptly and adequately corrected,” not that they inevitably will. Id. (emphasis added).

Consistent with this description, the warning letters at issue here advise the recipients that “it appears your ear candles are intended to mitigate or treat” the listed disorders, explain where to get the “information you need to submit in order to obtain approval or clearance for your device,” and state that “FDA will evaluate the information you submit and decide whether your product may be legally marketed.” FDA Warning Letter (J.A. 42-43) (emphasis added). They further state that “failure to promptly correct these deviations may result in regulatory action being initiated.” Id. (J.A. 43) (emphasis added). According to the letters, such regulatory actions “include, but are not limited to seizure, injunction, and/or civil monetary penalties.” Id. No such actions have been taken against the appellants to date.

Nor do the letters represent a decision determining rights or obligations, or one from which legal consequences flow. The FDA Manual explains that “[a] Warning Letter is the agency’s principal means of achieving prompt voluntary compliance with the Federal Food, Drug and Cosmetic Act.” FDA Manual, § 4-1-1 (emphasis added). Although a warning letter “communicates the agency’s position on a matter,” it is only “informal and advisory” and “does not commit FDA to taking enforcement action.” Id. Indeed, the Manual states that, “[djespite the significance of the violations [for which a warning letter may be issued], there are some circumstances that may preclude the agency from taking any further enforcement action following the issuance of a Warning Letter.” Id. In short, an FDA warning letter compels action by neither the recipient nor the agency.

Once again, the letters at issue here are consistent with the Manual’s description. The letters tell the manufacturers that they “should take prompt action to correct” the identified deviations, “request [ ]” that they cease marketing, promoting, and distributing ear candles, and state that “[f]ailure to promptly correct these deviations may result in regulatory action being initiated.” FDA Warning Letter (J.A. 43) (emphasis added). It is plain, therefore, that “[n]o legal consequences flow from the agency’s conduct to date, for there has been no order compelling [the appellants] to do anything.” Reliable Automatic Sprinkler, 324 F.3d at 732. ^[5]

Accordingly, like other agency advice letters that we have reviewed over the years, FDA warning letters do not repre[*945] sent final agency action subject to judicial review. ^[6] Ciba-Geigy Corp. v. EPA, 801 F.2d 430 (D.C.Cir.1986), cited by the appellants, is not to the contrary. In that case, the court determined that letters EPA sent to manufacturers were final because they expressed EPA’s “unequivocal position” that it could require labeling changes on a registered pesticide without first following the cancellation procedures prescribed by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), 7 U.S.C. § 136d(b). Cibctr-Geigy, 801 F.2d at 435-36; see Reckitt Benckiser Inc. v. EPA, 613 F.3d 1131, 1136-37 (D.C.Cir.2010). By contrast, FDA expresses no such position, unequivocal or otherwise, regarding its authority to regulate ear candles without taking further administrative action. To the contrary, it acknowledges that, for example, it may “only ban devices after going through a formal process that it has not undertaken here.” FDA Br. 19-20 (citing 21 U.S.C. § 360f). Moreover, unlike EPA, which “gave no indication that [its position was] subject to further agency consideration or possible modification,” Ciba-Geigy, 801 F.2d at 437, FDA advised the appellant manufacturers to submit further information, which it said it would “evaluate” and use to “decide whether [their] produces] may be legally marketed,” FDA Warning Letter (J.A. 43).

In support of their claim of finality, the appellants also point to language on FDA’s website and to the March 2010 meeting in which agency officials allegedly stated that FDA would never approve ear candles. FDA’s web page concerning ear candles lists a variety of actions taken by the agency in the past, including the issuance of warning letters, under a general heading entitled “[enforcement.” See FDA Consumer Update, Don’t Get Burned: Stay Away From Ear Candles (Feb. 18, 2010), http://www.fda.gov/For Consumers/ConsumerUpdates/ucm200277. htm. Such a generic heading, however, is insufficient to transform advisory letters into final agency action. ^[7] Similarly, a “statement or advice given by an FDA employee orally ... is an informal communication that ... does not necessarily represent the formal position of FDA, and does not bind or otherwise obligate or commit the agency to the views expressed.” 21 C.F.R. § 10.85(k); see id. § 10.65(a); cf. AT & T, 270 F.3d at 975[*946] (noting that agency action is not final when the “agency merely expresses its view of what the law requires of a party, even if that view is adverse to the party”). Moreover, FDA made clear in the March 2010 meeting, as it had in the warning letters, that it would await the appellants’ responses before taking any final regulatory action. See Certification in Support of Compl. ¶ 4 (“[W]e look forward to your response[,] ... and we will evaluate that response and make decisions.”). In short, neither FDA’s website nor the March 2010 meeting supplies the finality that the warning letters lack.

II

Because the February 2010 warning letters, even as supplemented by FDA’s website and the appellants’ conversations with FDA officials, do not constitute final agency action, the appellants’ complaint is not cognizable under the APA and must be dismissed for failure to state a claim. The district court’s order granting FDA’s motion to dismiss is therefore

affirmed.
