opinion: Justice THOMAS delivered the opinion of the Court.
  Under the Agricultural Marketing Agreement Act of 1937 (AMAA) and the California Raisin Marketing Order (Marketing Order or Order) promulgated by the Secretary of Agriculture, raisin growers are frequently required to turn over a percentage of their crop to the Federal Government. The AMAA and the Marketing Order were adopted to stabilize prices by limiting the supply of raisins on the market. Petitioners are California raisin growers who believe that this regulatory scheme violates the Fifth Amendment. After petitioners refused to surrender the requisite portion of their raisins, the United States Department of Agriculture (USDA) began administrative proceedings against petitioners that led to the imposition of more than $650,000 in fines and civil penalties. Petitioners sought judicial review, claiming that the monetary sanctions were an unconstitutional taking of private property without just compensation. The Ninth Circuit held that petitioners were required to bring their takings claim in the Court of Federal Claims and that it therefore lacked jurisdiction to review petitioners' claim. We disagree. Petitioners' takings claim, raised as an affirmative defense to the agency's enforcement action, was properly before the court because the AMAA provides a comprehensive remedial scheme that withdraws Tucker Act jurisdiction over takings claims brought by raisin handlers. Accordingly, we reverse and remand to the Ninth Circuit.
  I
  A
  Congress enacted the AMAA during the Great Depression in an effort to insulate farmers from competitive market forces that it believed caused "unreasonable fluctuations in supplies and prices." Ch. 296, 50 Stat. 246, as amended, 7 U.S.C. § 602(4). To achieve this goal, Congress declared a national policy of stabilizing prices for agricultural commodities. Ibid. The AMAA authorizes the Secretary of Agriculture to promulgate marketing orders that regulate the sale and delivery of agricultural goods. § 608c(1) ; see also Block v. Community Nutrition Institute, 467 U.S. 340, 346, 104 S.Ct. 2450, 81 L.Ed.2d 270 (1984) ("The Act contemplates a cooperative venture among the Secretary, handlers, and producers the principal purposes of which are to raise the price of agricultural products and to establish an orderly system for marketing them"). The Secretary may delegate to industry committees the authority to administer marketing orders. § 608c(7)(C).
  The AMAA does not directly regulate the "producer[s]" who grow agricultural commodities, § 608c(13)(B) ; it only regulates "handlers," which the AMAA defines as "processors, associations of producers, and others engaged in the handling" of covered agricultural commodities. § 608c(1). Handlers who violate the Secretary's marketing orders may be subject to civil and criminal penalties. §§ 608a(5), 608a(6), and 608c(14).
  The Secretary promulgated a marketing order for California raisins in 1949. See 14 Fed. Reg. 5136 (codified, as amended, at 7 CFR pt. 989 (2013)). In particular, "[t]he Raisin Marketing Order, like other fruit and vegetable orders adopted under the AMAA, [sought] to stabilize producer returns by limiting the quantity of raisins sold by handlers in the domestic competitive market." Lion Raisins, Inc. v. United States, 416 F.3d 1356, 1359 (C.A.Fed.2005). The Marketing Order defines a raisin "handler" as "(a) [a]ny processor or packer; (b) [a]ny person who places ... raisins in the current of commerce from within [California] to any point outside thereof; (c) [a]ny person who delivers off-grade raisins ... into any eligible non-normal outlet; or (d) [a]ny person who blends raisins [subject to certain exceptions]." 7 CFR § 989.15.
  The Marketing Order also established the Raisin Administrative Committee (RAC), which consists of 47 members, with 35 representing producers, ten representing handlers, one representing the cooperative bargaining associations, and one member of the public. See § 989.26. The Marketing Order authorizes the RAC to recommend setting up annual reserve pools of raisins that are not to be sold on the open domestic market. See 7 U.S.C. § 608c(6)(E) ; 7 CFR §§ 989.54(d) and 989.65. Each year, the RAC reviews crop yield, inventories, and shipments and makes recommendations to the Secretary whether or not there should be a reserve pool. § 989.54. If the RAC recommends a reserve pool, it also recommends what portion of that year's production should be included in the pool ("reserve-tonnage"). The rest of that year's production remains available for sale on the open market ("free-tonnage"). § 989.54(d), (a). The Secretary approves the recommendation if he determines that the recommendation would "effectuate the declared policy of the Act." § 989.55. The reserve-tonnage, calculated as a percentage of a producer's crop, varies from year to year. Under the Marketing Order's reserve requirements, a producer is only paid for the free-tonnage raisins. § 989.65. The reserve-tonnage raisins, on the other hand, must be held by the handler in segregated bins "for the account" of the RAC. § 989.66(f). The RAC may then sell the reserve-tonnage raisins to handlers for resale in overseas markets, or may alternatively direct that they be sold or given at no cost to secondary, noncompetitive domestic markets, such as school lunch programs. § 989.67(b). The reserve pool sales proceeds are used to finance the RAC's administrative costs. § 989.53(a). In the event that there are any remaining funds, the producers receive a pro rata share. 7 U.S.C. § 608c(6)(E) ; 7 CFR § 989.66(h). As a result, even though producers do not receive payment for reserve-tonnage raisins at the time of delivery to a handler, they retain a limited interest in the net proceeds of the RAC's disposition of the reserve pool.
  Handlers have other duties beyond managing the RAC's reserve pool. The Marketing Order requires them to file certain reports with the RAC, such as reports concerning the quantity of raisins that they hold or acquire. § 989.73. They are also required to allow the RAC access to their premises, raisins, and business records to verify the accuracy of the handlers' reports, § 989.77, to obtain inspections of raisins acquired, § 989.58(d), and to pay certain assessments, § 989.80, which help cover the RAC's administrative costs. A handler who violates any provision of the Order or its implementing regulations is subject to a civil penalty of up to $1,100 per day. 7 U.S.C. § 608c(14)(B) ; 7 CFR § 3.91(b)(1)(vii). A handler who does not comply with the reserve requirement must "compensate the [RAC] for the amount of the loss resulting from his failure to ... deliver" the requisite raisins. § 989.166(c).
  B
  Petitioners Marvin and Laura Horne have been producing raisins in two California counties (Fresno and Madera) since 1969. The Hornes do business as Raisin Valley Farms, a general partnership. For more than 30 years, the Hornes operated only as raisin producers. But, after becoming disillusioned with the AMAA regulatory scheme, they began looking for ways to avoid the mandatory reserve program. Since the AMAA applies only to handlers, the Hornes devised a plan to bring their raisins to market without going through a traditional handler. To this end, the Hornes entered into a partnership with Mrs. Horne's parents called Lassen Vineyards. In addition to its grape-growing activities, Lassen Vineyards purchased equipment to clean, stem, sort, and package the raisins from Raisin Valley Farms and Lassen Vineyards. It also contracted with more than 60 other raisin growers to clean, stem, sort, and, in some cases, box and stack their raisins for a fee. The Hornes' facilities processed more than 3 million pounds of raisins in toto during the 2002-2003 and 2003-2004 crop years. During these two crop years, the Hornes produced 27.4% and 12.3% of the raisins they processed, respectively.
  Although the USDA informed the Hornes in 2001 that their proposed operations made them "handlers" under the AMAA, the Hornes paid no assessments to the RAC during the 2002-2003 and 2003-2004 crop years. Nor did they set aside reserve-tonnage raisins from those produced and owned by the more than 60 other farmers who contracted with Lassen Vineyards for packing services. They also declined to arrange for RAC inspection of the raisins they received for processing, denied the RAC access to their records, and held none of their own raisins in reserve.
  On April 1, 2004, the Administrator of the Agriculture Marketing Service (Administrator) initiated an enforcement action against the Hornes, Raisin Valley Farms, and Lassen Vineyards (petitioners). The complaint alleged that petitioners were "handlers" of California raisins during the 2002-2003 and 2003-2004 crop years. It also alleged that petitioners violated the AMAA and the Marketing Order by submitting inaccurate forms to the RAC and failing to hold inspections of incoming raisins, retain raisins in reserve, pay assessments, and allow access to their records. Petitioners denied the allegations, countering that they were not "handlers" and asserting that they did not acquire physical possession of the other producers' raisins within the meaning of the regulations . Petitioners also raised several affirmative defenses, including a claim that the Marketing Order violated the Fifth Amendment's prohibition against taking property without just compensation.
  An Administrative Law Judge (ALJ) concluded in 2006 that petitioners were handlers of raisins and thus subject to the Marketing Order. The ALJ also concluded that petitioners violated the AMAA and the Marketing Order and rejected petitioners' takings defense based on its view that "handlers no longer have a property right that permits them to market their crop free of regulatory control." App. 39 (citing Cal-Almond, Inc. v. United States, 30 Fed.Cl. 244, 246-247 (1994) ).
  Petitioners appealed to a judicial officer who, like the ALJ, also found that petitioners were handlers and that they had violated the Marketing Order. The judicial officer imposed $202,600 in civil penalties under 7 U.S.C. § 608c(14)(B) ; $8,783.39 in assessments for the two crop years under 7 CFR § 989.80(a) ; and $483,843.53 for the value of the California raisins that petitioners failed to hold in reserve for the two crop years under § 989.166(c). The judicial officer believed that he lacked "authority to judge the constitutionality of the various statutes administered by the [USDA]," App. 73, and declined to adjudicate petitioners' takings claim.
  Petitioners filed a complaint in Federal District Court seeking judicial review of the USDA's decision. See 7 U.S.C. § 608c(14)(B). The District Court granted summary judgment to the USDA. The court held that substantial evidence supported the agency's determination that petitioners were "handlers" subject to the Marketing Order, and rejected petitioners' argument that they were exempt from the Marketing Order due to their status as "producers" under § 608c(13)(B). No. CV-F-08-1549LJOSMS, 2009 WL 4895362, at *15 (E.D.Cal., Dec. 11, 2009). Petitioners renewed their Fifth Amendment argument, asserting that the reserve-tonnage requirement constituted a physical taking.
  Though the District Court found that the RAC takes title to a significant portion of a California raisin producer's crop through the reserve requirement, the court held that the transfer of title to the RAC did not constitute a physical taking. See id., at *26 (" '[I]n essence, [petitioners] are paying an admissions fee or toll-admittedly a steep one-for marketing raisins. The Government does not force plaintiffs to grow raisins or to market the raisins; rather, it directs that if they grow and market raisins, then passing title to their "reserve tonnage" raisins to the RAC is the admissions ticket' " (quoting Evans v. United States, 74 Fed.Cl. 554, 563-564 (2006) )).
  The Ninth Circuit affirmed. The court agreed that petitioners were "handlers" subject to the Marketing Order's provisions, and rejected petitioners' argument that they were producers, and, thus exempt from regulation. 673 F.3d 1071, 1078 (2012). The court did not resolve petitioners' takings claim, however, because it concluded that it lacked jurisdiction to do so. The court explained that "a takings claim against the federal government must be brought [in the Court of Federal Claims] in the first instance, 'unless Congress has withdrawn the Tucker Act grant of jurisdiction in the relevant statute.' " Id., at 1079 (quoting Eastern Enterprises v. Apfel, 524 U.S. 498, 520, 118 S.Ct. 2131, 141 L.Ed.2d 451 (1998) (plurality opinion)). The court recognized that 7 U.S.C. § 608c(15) provides an administrative remedy to handlers wishing to challenge marketing orders under the AMAA, and it agreed that "when a handler, or a producer-handler in its capacity as a handler, challenges a marketing order on takings grounds, Court of Federal Claims Tucker Act jurisdiction gives way to section [60]8c(15)'s comprehensive procedural scheme and administrative exhaustion requirements." 673 F.3d, at 1079. But, the Ninth Circuit determined, petitioners brought the takings claim in their capacity as producers, not handlers. Id., at 1080. Consequently, the court was of the view that "[n]othing in the AMAA precludes the Hornes from alleging in the Court of Federal Claims that the reserve program injures them in their capacity as producers by subjecting them to a taking requiring compensation." Ibid. This availability of a Federal Claims Court action thus rendered petitioners' takings claim unripe for adjudication. Ibid.
  We granted certiorari to determine whether the Ninth Circuit has jurisdiction to review petitioners' takings claim. 568 U.S. ----, 133 S.Ct. 638, 184 L.Ed.2d 452 (2012).
  II
  A
  The Ninth Circuit's jurisdictional ruling flowed from its determination that petitioners brought their takings claim as producers rather than handlers. This determination is not correct. Although petitioners argued that they were producers-and thus not subject to the AMAA or Marketing Order at all-both the USDA and the District Court concluded that petitioners were "handlers." Accordingly, the civil penalty, assessment, and reimbursement for failure to reserve raisins were all levied on petitioners in their capacity as "handlers." If petitioners' argument that they were producers had prevailed, they would not have been subject to any of the monetary sanctions imposed on them. See 7 U.S.C. § 608c(13)(B) ("No order issued under this chapter shall be applicable to any producer in his capacity as a producer").
  It is undisputed that the Marketing Order imposes duties on petitioners only in their capacity as handlers. As a result, any defense raised against those duties is necessarily raised in that same capacity. Petitioners argue that it would be unconstitutional for the Government to come on their land and confiscate raisins, or to confiscate the proceeds of raisin sales, without paying just compensation; and, that it is therefore unconstitutional to fine petitioners for not complying with the unconstitutional requirement. SEE BRIEF FOR PETItioNers 54. given that fines Can only be levied on handlers, petitioners' takings claim makes sense only as a defense to penalties imposed upon them in their capacity as handlers . The Ninth Circuit confused petitioners' statutory argument (i.e., "we are producers, not handlers") with their constitutional argument (i.e., "assuming we are handlers, fining us for refusing to turn over reserve-tonnage raisins violates the Fifth Amendment").
  The relevant question, then, is whether a federal court has jurisdiction to adjudicate a takings defense raised by a handler seeking review of a final agency order.
  B
  The Government argues that petitioners' takings-based defense was rightly dismissed on ripeness grounds. Brief for Respondent 21-22. According to the Government, because a takings claim can be pursued later in the Court of Federal Claims, the Ninth Circuit correctly refused to adjudicate petitioners' takings defense. In support of its position, the Government relies largely on Williamson County Regional Planning Comm'n v . hamilTon bank Of johnsOn city, 473 U.S. 172, 105 S.CT. 3108, 87 l.ed.2d 126 (1985). Brief for Respondent 21-22 ("Just compensation need not 'be paid in advance of, or contemporaneously with, the taking; all that is required is that a 'reasonable, certain and adequate provision for obtaining compensation' exist at the time of the taking' " (quoting Williamson County, 473 U.S., at 194, 105 S.Ct. 3108) ). In that case, the plaintiff filed suit against the Regional Planning Commission, claiming that a zoning decision by the Commission effected a taking of property without just compensation. Id ., at 182, 105 S.Ct. 3108. We found that the plaintiff's claim was not "ripe" for two reasons, neither of which supports the Government's position.
  First, we explained that the plaintiff's takings claim in Williamson County failed because the plaintiff could not show that it had been injured by the Government's action. Specifically, the plaintiff "ha[d] not yet obtained a final decision regarding the application of the zoning ordinance and subdivision regulations to its property." Id., at 186, 105 S.Ct. 3108. Here, by contrast, petitioners were subject to a final agency order imposing concrete fines and penalties at the time they sought judicial review under § 608c(14)(B). This was clearly sufficient "injury" for federal jurisdiction.
  Second, the Williamson County plaintiff's takings claim was not yet ripe because the plaintiff had not sought "compensation through the procedures the State ha[d] provided for doing so." Id., at 194, 105 S.Ct. 3108. We explained that "[i]f the government has provided an adequate process for obtaining compensation, and if resort to that process yields just compensation, then the property owner has no claim against the Government for a taking." Id., at 194-195, 105 S.Ct. 3108 (internal quotation marks and alteration omitted). Stated differently, a Fifth Amendment claim is premature until it is clear that the Government has both taken property and denied just compensation. Although we often refer to this consideration as "prudential 'ripeness,' " Lucas v. South Carolina Coastal Council, 505 U.S. 1003, 1013, 112 S.Ct. 2886, 120 L.Ed.2d 798 (1992), we have recognized that it is not, strictly speaking, jurisdictional. See Stop the Beach Renourishment, Inc. v. Florida Dept. of Environmental Protection, 560 U.S. 702, ----, and n. 10, 130 S.Ct. 2592, 2610, and n. 10, 177 L.Ed.2d 184 (2010).
  Here, the Government argues that petitioners' takings claim is premature because the Tucker Act affords "the requisite reasonable, certain, and adequate provision for obtaining just compensation that a property owner must pursue." Brief for Respondent 22. In the Government's view, "[p]etitioners should have complied with the order, and, after a portion of their raisins were placed in reserve to be disposed of as directed by the RAC, ... sought compensation as producers in the Court of Federal Claims for the alleged taking." Id., at 24-25. We disagree with the Government's argument, however, because the AMAA provides a comprehensive remedial scheme that withdraws Tucker Act jurisdiction over a handler's takings claim. As a result, there is no alternative "reasonable, certain, and adequate" remedial scheme through which petitioners (as handlers) must proceed before obtaining review of their claim under the AMAA.
  The Court of Federal Claims has jurisdiction over Tucker Act claims "founded either upon the Constitution, or any Act of Congress or any regulation of an executive department."
  28 U.S.C. § 1491(a)(1). " [A] claim for just compensation under the Takings Clause must be brought to the Court of Federal Claims in the first instance, unless Congress has withdrawn the Tucker Act grant of jurisdiction in the relevant statute." Eastern Enterprises, 524 U.S., at 520, 118 S.Ct. 2131 (plurality opinion); see also United States v. Bormes, 568 U.S. ----, ----, 133 S.Ct. 12, 17, 184 L.Ed.2d 317 (2012) (where "a statute contains its own self-executing remedial scheme," a court "look[s] only to that statute"). To determine whether a statutory scheme displaces Tucker Act jurisdiction, a court must "examin[e] the purpose of the [statute], the entirety of its text, and the structure of review that it establishes." United States v. Fausto, 484 U.S. 439, 444, 108 S.Ct. 668, 98 L.Ed.2d 830 (1988).
  Under the AMAA's comprehensive remedial scheme, handlers may challenge the content, applicability, and enforcement of marketing orders. Pursuant to § 608c(15)(A)-(B), a handler may file with the Secretary a direct challenge to a marketing order and its applicability to him. We have held that "any handler" subject to a marketing order must raise any challenges to the order, including constitutional challenges, in administrative proceedings. See United States v. Ruzicka, 329 U.S. 287, 294, 67 S.Ct. 207, 91 L.Ed. 290 (1946). Once the Secretary issues a ruling, the federal district court where the "handler is an inhabitant, or has his principal place of business" is "vested with jurisdiction ... to review [the] ruling." § 608c(15)(B). These statutory provisions afford handlers a ready avenue to bring takings claim against the USDA. We thus conclude that the AMAA withdraws Tucker Act jurisdiction over petitioners' takings claim. Petitioners (as handlers) have no alternative remedy, and their takings claim was not "premature" when presented to the Ninth Circuit.
  C
  Although petitioners' claim was not "premature" for Tucker Act purposes, the question remains whether a takings-based defense may be raised by a handler in the context of an enforcement proceeding initiated by the USDA under § 608c(14). We hold that it may. The AMAA provides that the handler may not be subjected to an adverse order until he has been given "notice and an opportunity for an agency hearing on the record." § 608c(14)(B). The text of § 608c(14)(B) does not bar handlers from raising constitutional defenses to the USDA's enforcement action. Allowing handlers to raise constitutional challenges in the course of enforcement proceedings would not diminish the incentive to file direct challenges to marketing orders under § 608c(15)(A) because a handler who refuses to comply with a marketing order and waits for an enforcement action will be liable for significant monetary penalties if his constitutional challenge fails.
  In the case of an administrative enforcement proceeding, when a party raises a constitutional defense to an assessed fine, it would make little sense to require the party to pay the fine in one proceeding and then turn around and sue for recovery of that same money in another proceeding. See Eastern Enterprises, supra, at 520, 118 S.Ct. 2131. We see no indication that Congress intended this result for handlers subject to enforcement proceedings under the AMAA. Petitioners were therefore free to raise their takings-based defense before the USDA. And, because § 608c(14)(B) allows a handler to seek judicial review of an adverse order, the district court and Ninth Circuit were not precluded from reviewing petitioners' constitutional challenge. The grant of jurisdiction necessarily includes the power to review any constitutional challenges properly presented to and rejected by the agency. We are therefore satisfied that the petitioners raised a cognizable takings defense and that the Ninth Circuit erred in declining to adjudicate it.
  III
  The Ninth Circuit has jurisdiction to decide whether the USDA's imposition of fines and civil penalties on petitioners, in their capacity as handlers, violated the Fifth Amendment. The judgment of the Ninth Circuit is reversed, and the case is remanded for further proceedings consistent with this opinion.
  It is so ordered.
  The AMAA also applies to a vast array of other agricultural products, including "[m]ilk, fruits (including filberts, almonds, pecans and walnuts ..., pears, olives, grapefruit, cherries, caneberries (including raspberries, blackberries, and loganberries), cranberries, ... tobacco, vegetables, ... hops, [and] honeybees." § 608c(2).
  In 2002-2003 and 2003-2004, the crop years at issue here, the reserve percentages were set at 47 percent and 30 percent of a producer's crop, respectively. See RAC, Marketing Policy & Industry Statistics 2012, p. 28 (Table 12).
  The Hornes wrote the Secretary and to the RAC in 2002 setting out their grievances: "[W]e are growers that will pack and market our raisins. We reserve our rights under the Constitution of the United States ... [T]he Marketing Order Regulating Raisins has become a tool for grower bankruptcy, poverty, and involuntary servitude. The Marketing Order Regulating Raisins is a complete failure for growers, handlers, and the USDA ... [W]e will not relinquish ownership of our crop. We put forth the money and effort to grow it, not the Raisin Administrative Committee. This is America, not a communist state." App. to Pet. for Cert. 60a.
  The Ninth Circuit construed the takings argument quite differently, stating that petitioners believe the regulatory scheme "takes reserve-tonnage raisins belonging to producers." 673 F.3d 1071, 1080 (2012). When the agency brought its enforcement action against petitioners, however, it did not seek to recover reserve-tonnage raisins from the 2002-2003 and 2003-2004 crop years. Rather, it sought monetary penalties and reimbursement. Petitioners could not argue in the face of such agency action that the Secretary was attempting to take raisins that had already been harvested and sold. Instead, petitioners argued that they could not be compelled to pay fines for refusing to accede to an unconstitutional taking.
  The Government notes that petitioners did not own most of the raisins that they failed to reserve and argues that petitioners would have no takings claim based on those raisins. See Brief for Respondent 19. We take no position on the merits of petitioners' takings claim. We simply recognize that insofar as the petitioners challenged the imposition of monetary sanctions under the Marketing Order, they raised their takings-based defense in their capacity as handlers. On remand, the Ninth Circuit can decide in the first instance whether petitioners may raise the takings defense with respect to raisins they never owned.
  A "Case" or "Controversy" exists once the government has taken private property without paying for it. Accordingly, whether an alternative remedy exists does not affect the jurisdiction of the federal court.
  That is not to say that a producer who turns over her reserve-tonnage raisins could not bring suit for just compensation in the Court of Claims. Whether a producer could bring such a claim, and what impact the availability of such a claim would have on petitioners' takings-based defense, are questions going to the merits of petitioners' defense, not to a court's jurisdiction to entertain it. We therefore do not address those issues here.
  Petitioners filed an administrative petition before the Secretary in March 2007 pursuant to § 608c(15)(A) challenging the Marketing Order and its application to them. The USDA argued that they had no standing to file the petition because they had not admitted that they were handlers. The judicial officer granted the USDA's motion to dismiss the petition for lack of jurisdiction. Petitioners filed a complaint in District Court, but the court dismissed it as untimely. The Ninth Circuit affirmed. See Horne v. Dept. of Agriculture, 395 Fed.Appx. 486 (2010).
