LEVIN H. CAMPBELL, Senior Circuit Judge.

Plaintiff-appellant TAG/ICB Services, Inc., as agent of Crowley American Transport, Inc. (“TAG/ICB”), appeals from the district court’s dismissal of its demurrage complaint on statute of limitations grounds. We reverse, holding that TAG/ ICB’s complaint is not time-barred, and remand for further proceedings not inconsistent with this opinion.

The following facts are undisputed: TAG/ICB is a common water carrier in domestic trade between ports in the United States and Puerto Rico. On multiple occasions, defendant-appellees Pan American Grain Company, Inc. and Pan American Grain Manufacturing Company, Inc. (“Pan American”) used TAG/ICB’s services and facilities for the transportation of cargo between United States and Puerto Rican ports. The transportation was subject to federally regulated tariffs.

The tariffs provided for a period of time during which Pan-American was allowed to load or unload containers at places of origin and destination free of charge (“free time”). After the expiration of the free time, Pan-American was required to pay a demurrage charge for each additional day it retained a container. 1 On several occasions between July 1, 1994, and March 3, 1997, Pan-American retained containers beyond the free-time period. TAG/ICB sent demurrage invoices to Pan-American detailing the occasions when demurrage occurred, the number of the bill of lading, the trailer number, the starting and ending dates of the free time and demurrage, and the amount charged. Pan-American did not pay on these invoices. As of March 14, 1997, there was an outstanding balance of $142,665.00 in demurrage and $49,932.75 in administrative collection fees.

On May 11, 1998, TAG/ICB filed a complaint against Pan-American for collection of the demurrage and fees, invoking the district court’s jurisdiction pursuant to 28 U.S.C. §§ 1331, 1333, and 1337 and Fed. R.Civ.P. 9(h). Attached to the complaint were the invoices setting forth the outstanding charges, which were dated July 7, 1994, through March 14, 1997. TAG/ICB sought damages in the amount of $192,-597.75.

On or about June 22, 1998, Pan-American filed a motion to dismiss, asserting that the action was time-barred under the Puerto Rico Code of Commerce, which provides a six-month limitation period. See 10 L.P.R.A. § 1909. 2 TAG/ICB op *175 posed the motion, contending that the doctrine of laches and federal maritime law instead determined the time to sue. It urged the court to look to the Interstate Commerce Act, as the most analogous statute, which contained a three-year statute of limitations.

On March 30, 1999, the district court allowed Pan-American’s motion to dismiss. See TAG/ICB Servs., Inc. v. Pan Am. Grain Co., Inc., No. CIV.A. 98-1497, 1999 WL 305238 (D.P.R., Mar.31,1999). Applying the six-month limitations period contained in the Puerto Rico Code of Commerce, the court concluded that TAG/ ICB’s claim was time-barred in its entirety, as the last invoice TAG/ICB issued for collection of demurrage was dated over a year before it filed its complaint.

On April 21, TAG/ICB moved to vacate judgment. In addition to reasserting that laches and maritime law applied, TAG/ICB noted that Congressional changes to maritime law set forth in the Interstate Commerce Commission Termination Act of 1995, 49 U.S.C. §§ 10101 et seq. (“ICC-TA”), created an eighteen-month statute of limitations that governs this action. The district court denied TAG/ICB’s motion. TAG/ICB appeals from both the dismissal order and the denial of its motion to vacate.

II.

This court applies a de novo standard of review to a district court’s allowance of a motion to dismiss for failure to state a claim. See New England Cleaning Servs., Inc. v. American Arbitration Ass’n, 199 F.3d 542, 544 (1st Cir.1999). We accept as true the well-pleaded factual allegations of the complaint, draw all reasonable inferences therefrom in the plaintiffs favor, and determine whether the complaint, so read, sets forth facts sufficient to justify recovery on any cognizable theory. See LaChapelle v. Berkshire Life Ins. Co., 142 F.3d 507, 508 (1st Cir.1998). Here, the sole issue on appeal is whether the district court applied the correct time bar to TAG/ICB’s demurrage claim.

TAG/ICB asserted its claim under the federal courts’ admiralty jurisdiction, 28 U.S.C. § 1333. 3 In an admiralty case, maritime law and the equitable doctrine of laches govern the time to sue. See Butler v. American Trawler Co., Inc., 887 F.2d 20 (1st Cir.1989); Puerto Rican-American Ins. Co. v. Benjamin Shipping Co. Ltd., 829 F.2d 281, 283 (1st Cir.1987). When applying the doctrine of laches, the court examines whether plaintiffs delay in bringing suit was unreasonable and whether defendant was prejudiced by the delay. See Puerto Rican-American Ins. Co., 829 F.2d at 283.

In the maritime context, a laches analysis utilizes as a benchmark the limitations period contained in the most analogous statute. See id. That limitations period is not per se dispositive, but rather courts rely upon it to establish burdens of proof and presumptions of timeliness and untimeliness. Hence, “if a plaintiff files a complaint within the analogous statutory period, the burden of proving unreasonable delay and prejudice falls on the defen *176 dant. If a plaintiff files after the statutory-period has expired, the burden shifts and a presumption of laches is created.” See id. (internal citations omitted). The analogous limitation period can be located either in state or federal law. See, e.g., id. (applying Puerto Rico negligence statute of limitations to maritime tort claim); Angela Compania Naviera, 592 F.2d at 61 (applying two-year statute of limitations contained in federal Death on the High Seas Act to maritime wrongful death action); Giddens v. Isbrandtsen Co., 355 F.2d 125, 127 (4th Cir.1966) (applying federal Jones Act statute of limitations to maritime tort).

Here, we are satisfied that the most analogous statutes are the federal statutes regulating the very tariffs under which the alleged demurrages arose: the Shipping Act of 1916, 46 U.S.CApp. §§ 801 et seq. (“Shipping Act”), until its effective repeal date of September 30, 1996, and thereafter the ICCTA. Section 18 of the Shipping Act required common carriers by water in interstate commerce to “establish, observe, and enforce just and reasonable rates, fares, charges, classifications and tariffs,” and to file tariffs showing all rates and charges with the Federal Maritime Commission. See 46 U.S.C.App. § 817 (repealed 1995). The ICCTA contains similar requirements, but specifies that the tariffs must now be filed with the Surface Transportation Board. See 49 U.S.C. § 13702.

This court has held that maritime carriers have a private federal cause of action to recover container demurrage charges specified in tariffs under the Shipping Act (as well as under the Intercoastal Shipping Act of 1933, 46 U.S.C.App. § 843 (repealed 1995)). See Maritime Serv. Corp., 537 F.2d at 562-63. Hence, the Shipping Act pertained to TAG/ICB’s demurrage actions until its repeal on September 30, 1996. See 46 U.S.C. § 817, repealed by Pub.L. No. 104-88, § 335(b) (1995).

Although the Shipping Act does not itself contain a statute of limitations, the three-year statute of limitations set forth in a related statute, the Interstate Commerce Act (ICA), 49 U.S.C. §§ 10701 et seq., has been held to pertain to container demurrage actions such as this. See Puerto Rico Marine Management, Inc. v. Molac Imports, Inc., 594 F.Supp. 648, 651 (D.P.R.1984); Puerto Rico Marine Management v. El Verde Poultry Farms, Inc., 590 F.Supp. 1174, 1176-77 (D.P.R.1984). 4 In Maritime Serv. Corp., we noted that the relevant provisions of the Shipping Act were modeled on the ICA. See 537 F.2d at 562; see also United States Navigation Co. v. Cunard S.S. Co., 284 U.S. 474, 481, 52 S.Ct. 247, 76 L.Ed. 408 (1932) (“Congress intended that the two acts, each in its own field, should have like interpretation, application and effect.”). The two statutes share the common purposes of eliminating discriminatory rates and securing the uniformity of transportation charges. See Maritime Serv. Corp., 537 F.2d at 563; Molac, 594 F.Supp. at 651.

Pan American contends the district was correct in concluding that the Puerto Rico Code of Commerce is the most analogous statute. 5 See id. While *177 that statute is certainly broad enough to apply to a demurrage action such as this, an admiralty court must apply the federal maritime rules that directly address the issues at hand, and only resort to state law when no federal rule applies. See Greenly v. Mariner Management Group, Inc., 192 F.3d 22, 25-26 (1st Cir.1999); cf. DelCostello v. Int’l Bhd. of Teamsters, 462 U.S. 151, 161-162, 103 S.Ct. 2281, 76 L.Ed.2d 476 (1983) (state statutes of limitations should not be “borrowed” if they are unsatisfactory vehicles for enforcement of federal law); Occidental Life Ins. Co. v. Equal Employment Opportunity Comm’n., 432 U.S. 355, 367, 97 S.Ct. 2447, 53 L.Ed.2d 402 (1977) (“State legislatures do not devise their limitations periods with national interests in mind, and it is the duty of the federal courts to assure that the importation of state law will not frustrate or interfere with the implementation of national policies.”). The policy considerations noted supra favor the application of the federal ICA to TAG/ICB’s federally based demurrage claim. To subject de-murrage actions to a variety of local limitations periods would undermine the uniformity Congress intended, as well as the policy against discriminatory rates, especially in fora having short limitations periods. See Molac, 594 F.Supp. at 651.

Effective September 30, 1996, the ICC-TA replaced the relevant provisions of the Shipping Act. See 46 U.S.CApp. § 817, repealed by Pub.L. No. 104-88, § 335(b) (1995); see also Pub.L. 103-429, § 10, 108 Stat. 4391 (1994). 6 The ICCTA thereupon replaced the Shipping Act and ICA as the most analogous statute for purpose of lach-es. Unlike the Shipping Act, the ICCTA contains a limitations period of its own. It prescribes a statute of limitations of eighteen months for all actions relating to transportation services:

(a) A carrier providing transportation or • service subject to jurisdiction under chapter 135 must begin a civil action to recover charges for transportation or service provided by the carrier within 18 months after the claim accrues.

(g) A claim related to a shipment of property accrues under this section on delivery or tender of delivery by the carrier.

49 U.S.C.A. § 14705. We hold, therefore, that the ICA’s three-year statute of limitations, which was imported into the Shipping Act, supplies the benchmark limitations period during the time when the Shipping Act governed TAG/ICB’s demur-rage claims; and that thereafter, the eighteen-month statute of limitations contained in the ICCTA is the presumptive benchmark for the claims.

Pan-American suggests that the Puerto Rico Federal Relations Act (“FRA”), 48 U.S.C. §§ 731 et seq., precludes application of the ICCTA to this matter. Section 8 of the FRA provides that “[a]ll laws of the United States for the protection and improvement of the navigable waters of the United States and the preservation of the interests of navigation and commerce, except so far as the same may be locally inapplicable, shall apply to” Puerto Rico and its waters. 48 U.S.C. § 749; see also id. § 734 (providing, in *178 relevant part, that “[t]he statutory laws of the United States not locally inapplicable, except as hereinbefore or hereinafter otherwise provided, shall have the same force and effect in Puerto Rico as in the United States”).

The ICCTA, like the Shipping Act, plainly protects the interests of navigation and commerce. Cf Maritime Serv. Corp., 537 F.2d at 561 (Shipping Act and Inter-coastal Shipping Act “indisputably regulate commerce”). We see no basis for determining that the ICCTA is “locally inapplicable” to Puerto Rico such that it should not be applied to this action. See United States v. Rivera Torres, 826 F.2d 151, 154 (1st Cir.1987) (holding that Clean Water Act applied to Puerto Rico, notwithstanding FRA). The Shipping Acts preceding the ICCTA were consistently applied to demurrage and other actions involving waters in Puerto Rico. See, e.g., Puerto Rico Ports Auth. v. Federal Maritime Comm’n, 642 F.2d 471, 476 (D.C.Cir.1980); Capitol Transp., Inc. v. United States, 612 F.2d 1312, 1325 (1st Cir.1979); Maritime Serv. Corp., 537 F.2d at 561. Moreover, Pan American does not point to anything in the legislative history of the ICCTA that would indicate that Congress did not intend that statute to apply to Puerto Rico. See Rivera Torres, 826 F.2d at 154.

Pan American bases its contrary argument solely on the FRA’s provision that the ICA “and the several amendments made or to be made thereto” do not apply to Puerto Rico. See 48 U.S.C. § 751. Because the ICCTA amends the ICA, it contends, the ICCTA likewise does not apply to Puerto Rico. Section 751, however, has been interpreted to refer only to intra-island Puerto Rico transportation, “and neither gives Puerto Rico the right to regulate interstate commerce nor precludes federal regulation of interstate commerce involving Puerto Rico.” Trailer Marine Transport Corp. v. Dolphin Forwarding, Inc., 758 F.Supp. 796, 797 (D.P.R.1991); see also Trailer Marine Transport Corp. v. Federal Maritime Comm’n, 602 F.2d 379, 385 n. 26 (D.C.Cir.1979) (citing Benedicto v. West India & Panama Telegraph Co., 256 F. 417, 420 (1st Cir.1919)). We are not persuaded, therefore, that the ICCTA is locally inapplicable to Puerto Rico.

Finally, Pan-American argues that TAG/ICB waived its ICCTA argument by not making it in its opposition to the motion to dismiss. In its opposition, TAG/ICB maintained that the three-year limitations period contained in the Interstate Commerce Act should apply to de-murrage claims such as this. It was not until its motion to vacate judgment that TAG/ICB mentioned the ICCTA. Pan-American maintains that even at that point, TAG/ICB did not make any developed argument concerning the ICCTA. This contention is undermined by the fact that Pan-American vigorously contested the application of the ICCTA in its response to TAG/ICB’s motion to vacate judgment. We believe, therefore, that TAG/ICB sufficiently preserved the issue. Moreover, under Rule 12(b)(6), a court must determine whether the complaint sets forth facts sufficient to justify recovery on any cognizable theory. See LaChapelle, 142 F.3d at 508.

We thus conclude that the ICA and the ICCTA supply the relevant benchmark statutes of limitation for TAG/ICB’s maritime demurrage claim. To summarize, TAG/ICB’s maritime claim, to the extent that it was governed by the Shipping Act — i.e., from July, 1994, to September 30, 1996 — is presumptively subject to the three-year statute of limitation contained in the ICA. The ICCTA’s eighteen-month statute of limitations presumptively applies to TAG/ICB’s demurrage claim accruing after September 30, 1996, when the ICC-TA replaced the Shipping Act. See 49 U.S.C. § 14705(a); In re Apex Exp. Corp., 190 F.3d 624, 642 (4th Cir.1999) (ICCTA statute of limitations operates only prospectively).

*179 Under the laches analysis, the above limitation periods are not dispositive; rather, they presumptively establish the claim’s timeliness or untimeliness subject to further germane considerations. See Puerto Rican-American Ins. Co., 829 F.2d at 283. The district court did not address the other issues relevant to the laches determination — e.g., whether TAG/ICB’s delay was unreasonable and whether Pan-American suffered prejudice from the delay — nor have the parties briefed these issues to this court. In all events, the resolution of such issues plainly calls for a better developed record (and, quite possibly, for the taking of evidence). Accordingly, the laches issues remain open for the district court to determine on remand.

Reversed and remanded for further proceedings not inconsistent with this opinion.

. “Demurrage” is remuneration of a shipowner for the detention of its vessel beyond the number of days allowed by the charter-party. See Black's Law Dictionary 432 (6th ed.1990).

. This section provides, in relevant part, that "actions relating to the collection of transportation, freights, expenses inherent thereto, and the contributions of ordinary averages shall prescribe six months after the goods *175 which gave rise thereto were delivered.” 10 L.P.R.A. § 1909.

. In its complaint, TAG/ICB also referenced 28 U.S.C. § 1337(a), which grants federal jurisdiction over a "civil action ... arising under any Act of Congress regulating commerce.” Maritime carriers have a private federal cause of action under § 1337(a) jurisdiction to recover demurrage charges specified in tariffs set forth in certain commerce-related statutes, see Maritime Serv. Corp. v. Sweet Brokerage De Puerto Rico, Inc., 537 F.2d 560, 562-63 (1st Cir.1976). However, TAG/ICB did not, either in the district court or in its appellate brief, argue the applicability of § 1337(a). Hence, we confine our review to TAG/ICB’s argument based on general maritime law and the doctrine of laches. In doing so, we do not mean to necessarily rule out the possibility that a demurrage claim such as this could be pursued under separate § 1337(a) jurisdiction, in which event the same statutes of limitation found herein to be most analogous for laches purposes might control directly.

. The El Verde court applied the doctrine of laches and concluded that the ICA was the most analogous statute. See 590 F.Supp. at 1176. In Molac, the plaintiff invoked jurisdiction under 28 U.S.C. § 1337 (acts regulating commerce), not the admiralty jurisdiction statute. See 594 F.Supp. at 649. The district court did not, therefore, apply the doctrine of laches, but held that policy considerations favored the direct application of the ICA statute of limitations rather than the Puerto Rico local law. See id.

. We do not find the reasoning in Mortensen & Lange v. San Juan Mercantile Corp., 119 D.P.R. 345 (1987), the case upon which the district court primarily relied, to be persuasive in this case. In Mortensen, the Puerto Rico Supreme Court held that Article 947 provided the applicable limitations period to a freight contract between two parties shipping lumber between Puerto Rico and Honduras. The Court held that Article 947’s six-month caducity period was directly applicable to the action at issue, as it was enacted by the Puer-to Rico Legislature under its power to legis *177 late with regard to maritime matters, and the suit was for collection of monies related to expenses inherently related to the freight. Id. at 358. For aught that appears, the Shipping Act, the ICA, and the ICCTA were not at issue there.

. Section 10 of Pub.L. 103-429 provides, in relevant part:

(a) No substantive change. — This Act restates, without substantive change, laws enacted before September 26, 1994, that were replaced by this Act. This Act may not be construed as making a substantive change in the laws replaced. ...

(b) References. — A reference to a law replaced by this Act, including a reference in a regulation, order, or other law, is deemed to refer to the corresponding provision enacted by this Act....

(d) Actions and offenses under prior law. — -An action taken or an offense committed under a .law replaced by this Act is deemed to have been taken or committed under the corresponding provision enacted by this Act.
