Claimants appeal the district court’s judgment that they must forfeit $194,-209.04 for violating the Currency and Foreign Transactions Reporting Act, 31 U.S.C. § 5311 et seq. Although the result in this case is undeniably harsh, as are most forfeiture actions, we are constrained to affirm with a modification.
FACTS
Raul Arvizo-Morales is an employee at Casa de Cambio Juarez, a monetary exchange business located in Juarez, Mexico. On April 23, 1986, Arvizo-Morales completed Customs Form 4790, Report of International Transportation of Currency or Monetary Instruments, indicating that Casa de Cambio was depositing currency of $172,-081.04 and checks totalling $70,772.55 into its account at Texas Commerce Bank (TCB) in El Paso.1 Just before Arvizo-Morales left to make the deposit, Francisco Arvizo-Morales, a principal owner of Casa de Cam-bio and Raul’s brother, told him to take $19,685.04 from the total currency and deliver it to Don Peso’s Money Exchange House for payment of pesos purchased by Casa de Cambio from Don Peso’s a day earlier. Arvizo-Morales then placed $19,-685.04 in a separate bag and left for El Paso without revising Form 4790 to indicate that the money was being taken to two destinations.
Arvizo-Morales presented Form 4790 to Customs Agent Marcos Payan at the border. When asked whether the information on Form 4790 was correct, ArvizoMorales said yes. At Payan’s request, Arvizo-Morales walked back to his vehicle and returned to the Customs office with the two bags of money. When Payan asked whether the money in both bags was being taken to TCB Arvizo-Morales indicated that the bag containing $19,685.04 was being taken to Don Peso’s. Payan then counted $20,685.04 in the separate bag. Both Pay-an and Arvizo-Morales then recounted the money and still noted a $1,000 difference. Payan then declined Arvizo-Morales’ request to modify Form 4790 2 and seized all of the currency and checks.3 Payan testified that he had three reasons for seizing the money: The report did not list Don Peso’s as a destination, the report did not indicate that Arvizo-Morales was acting as an agent for Don Peso’s, and the reported amount of money was off by $1,000.
The district court ordered forfeiture of all of the currency and the single negotiable check for $21,128.06 after concluding that the claimants’ failure to list Don Peso’s as a destination was a material misstatement or omission that was knowingly made,4 652 F.Supp. 1468. We address two issues on appeal: whether the Government was required to prove that the claimants knowingly failed to list Don Peso’s as a destination, and whether only that portion of the money destined for Don Peso’s should have been forfeited.
INTENT TO MISREPRESENT OR OMIT
The district court, relying on numerous facts, concluded that the claimants filed Form 4790 knowing that it contained a material omission or misstatement. The claimants concede that their failure to list Don Peso’s as a destination was material. See 31 U.S.C. § 5316(b). They allege, however, that such failure was not knowingly done but was the result of an accident, inadvertent mistake, or innocent error. They point out numerous facts to buttress their contention.
*1143Whether the facts indicate that the claimants’ failure to list Don Peso’s as a destination was intentional or inadvertent is irrelevant. At the time of this event, 31 U.S.C. § 5317(c) provided in relevant part: “A monetary instrument being transported may be seized and forfeited to the United States Government when a report on the instrument ... has not been filed or contains a material omission or misstatement.” 5 We have held that a party must have knowledge of the reporting requirements before his money is subject to forfeiture under § 5317(c). See United States v. Granda, 565 F.2d 922 (5th Cir.1978); see also United States v. One Lot of $24,900 in U.S. Currency, 770 F.2d 1530 (11th Cir.1985); United States v. $48,595, 705 F.2d 909 (7th Cir.1983). But see United States v. $359,500 in United States Currency, 828 F.2d 930 (2d Cir. 1987); United States v. $47,980 in Canadian Currency, 804 F.2d 1085 (9th Cir.1986); United States v. $20,757.83 in Canadian Currency, 769 F.2d 479 (8th Cir.1985). These cases offer no assistance here, however, because this is not a failure-to-report case. Rather, these claimants, well aware of the reporting requirements, nevertheless filed a report containing a material misstatement or omission. Section 5317(c) only requires that the misstatement or omission be “material” before the filing party’s money becomes subject to forfeiture. The statutory language does not require examination of the party’s mental state and the district court’s finding of a “knowing” misstatement was therefore unnecessary. Cf. § 5316(a) (“knowingly transports”); § 5322(a) & (b) (“willfully violating”). Under the clear and unambiguous language of § 5317(c), the claimant’s money became subject to forfeiture when Arvizo-Morales tendered the materially incorrect Form 4790 to Payan, regardless of whether the reporting error was intentional or inadvertent.
Claimants argue that under regulations applicable to tariff collection, 19 C.F.R. § 148.16, a declaration made before examination of one’s baggage has begun may be amended after the commencement of the inspection if undeclared articles have not yet been found and the officer perceives no fraudulent intent. They would have their conduct tested against this standard. Although the Treasury Department might sensibly promulgate a regulation permitting amendments to Form 4790 reports for the purpose of correcting inadvertent errors, it has not done so, and there is no suggestion in the language of 19 C.F.R. § 148.16 or elsewhere that renders it susceptible to application in currency forfeitures. We cannot accept this defense.
FORFEITURE
The claimants alternatively contend that because the reporting violation found by the district court concerns only the funds destined for Don Peso’s, only those funds should be subject to forfeiture. This argument is appealing, especially because the record overwhelmingly suggests that the reporting error was simply an oversight and would never have come to the Government’s attention but for the candor of Arvizo-Morales. We agree with the district court, however, that the federal judiciary has no statutory authority to reduce the forfeiture amount in this case.6
As the district court noted, 31 C.F.R. § 103.48, enacted pursuant to the Currency and Foreign Transactions Reporting Act, provides:
Any currency or other monetary instruments which are in the process of any transportation with respect to which a report is required ... are subject to sei*1144zure and forfeiture to the United States if such report ... contains material omissions or misstatements. The Secretary [of the Treasury] may, in his sole discretion, remit or mitigate any such forfeiture in whole or in part upon such terms and conditions as he deems reasonable. (emphasis added)7
This regulation indicates that all money associated with the materially incorrect report is subject to forfeiture and that only the Secretary of the Treasury has discretion to remit any or all of the forfeited funds. By negative implication, no power to ameliorate an individual forfeiture has been conferred on the federal courts. Claimants cite no authority supporting their position, and this court has previously rejected imposing a partial forfeiture. United States v. Currency Totalling $48,318.08, 609 F.2d 210 (5th Cir.1980).
The claimants argue that the unfairness of forfeiture is compounded because they were never given an opportunity to request mitigation of forfeiture from the Secretary of the Treasury, and are precluded from doing so now, since the Government removed the claim from administrative review by filing its complaint in federal district court only eight days after the funds were seized. We can find no federal statute or regulation barring administrative review of a claim once a party has filed a complaint in federal district court. In view of the twin facts that the claimants had the right to contest the propriety of the forfeiture and that we have no authority to order partial forfeiture, we see no reason why claimants’ claim for administrative relief has been waived by awaiting the outcome of this case. Our decision is thus entered without prejudice to claimants’ exercise of administrative remedies.8
The judgment of the district court is AFFIRMED as modified.
. Arvizo-Morales completed Form 4790 because he was transporting monetary instruments of more than $10,000 into the United States. See 31 U.S.C. § 5316(a)(1)(B). He previously had completed dozens of these forms.
. The record is unclear whether Arvizo-Morales requested to modify the amount, the destination, or both.
. Payan subsequently returned checks totalling $49,644.49 because they were non-negotiable. Non-negotiable checks are not required to be reported on Form 4790. See 31 U.S.C. § 5312(a)(3).
. The district court did not support its forfeiture decision by relying upon Payan’s additional reasons for seizing the money, nor does the Government urge those other reasons on appeal.
. Section 5317(c) was amended in October 1986 and now reads as follows: "If a report required under section 5316 with respect to any monetary instrument is not filed (or if filed, contains a material omission or misstatement of fact), the instrument and any interest in property, including a deposit in a financial institution, traceable to such instrument may be seized and forfeited to the United States Government ... .”
. Whether the forfeiture amount could sustain constitutional attack is not before us, as claimants have raised no constitutional challenges in this case. Cf. United States v. Busher, 817 F.2d 1409 (9th Cir.1987) (RICO forfeitures may violate Eighth Amendment); but see United States v. Grande, 620 F.2d 1026 (4th Cir.), cert. denied, 449 U.S. 830, 101 S.Ct. 98, 66 L.Ed.2d 35 (1980).
. See also 31 U.S.C. § 5317(c) (Monetary instruments being transported may be seized and forfeited if report is materially incorrect); 31 U.S. C. § 5321(c) ("The Secretary may remit any part of a forfeiture" under § 5317(c)). In the absence of 31 U.S.C. § 5321(c) or 31 C.F.R. § 103.48, “the Secretary would be unable to correct an injustice if evidence came to light that a penalty which had been paid had been unjustly imposed." H.Rep.No. 91-975, 91st Cong., 2d Sess., reprinted in 1970 U.S.Code Cong. & Admin.News 4394, 4408. See also S.Rep.No. 91-1139, 91st Cong., 2d Sess. at 7 (1970) (The Secretary has discretion to remit any part of a forfeiture "to prevent ordinary citizens or businessmen from being unduly penalized for an inadvertent violation.”).
. The Currency and Foreign Transactions Reporting Act vests the Commissioner of Customs with authority to enforce compliance with the reporting and forfeiture provisions at issue here. See 31 C.F.R. § 103.46(b)(7). We will not speculate on the precise administrative procedure that applies here, observing only that one Customs statute, if it applies, provides that a person whose property has been seized can petition the Secretary of the Treasury for redress. See 19 U.S.C. § 1618. A regulation enacted pursuant to 19 U.S.C. § 1618 provides that the claimant must file his petition for relief "within 30 days from the date of the mailing of the notice of fine, penalty, or forfeiture incurred." 19 C.F.R. § 171.12(b). According to 19 C.F.R. § 162.31(a), the notice of forfeiture must inform the claimant that he can seek relief under 19 U.S.C. § 1618 or any other applicable statute authorizing remission of forfeitures.
