OPINION
This appeal arises from a pay dispute between the defendant, Sara Lee Corporation, and the named plaintiffs, David C. Anderson and Samuel Pullen, as representatives of a class that includes approximately 1600 hourly production workers employed at Sara Lee’s bakery in Tarboro, North Carolina (the “Class Members”). The Class Action Complaint alleges five claims under North Carolina law — for breach of contract, negligence, fraud, conversion, and unfair trade practices — each relating to Sara Lee’s failure to compensate the Class Members for time spent complying with a mandatory uniform policy.
Early in the district court proceedings, Sara Lee sought dismissal of all five claims on the ground that they are preempted by the Fair Labor Standards Act of 1938, 29 U.S.C. §§ 201-219 (the “FLSA”) (creating enforceable federal rights to minimum wage and overtime compensation). The court rejected Sara Lee’s preemption contention, but dismissed with prejudice three of the five claims — the fraud, conversion, and unfair trade practices claims — under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which relief can be granted. See Anderson v. Sara Lee Corp., No. CA-03-31-H (E.D.N.C. Apr. 14, 2003) (the “Dismissal Order”). Following discovery, the court awarded summary judgment to Sara Lee under Rule 56(c) on the remaining contract and negligence claims. See Anderson v. Sara Lee Corp., No. CA-03-31-H (E.D.N.C. Dec. 7, 2004) (the “Summary Judgment Order”). On appeal, the Class Members challenge the propriety of both the Dismissal Order and the Summary Judgment Order, which Sara Lee defends on various grounds, including FLSA preemption.
*183 As explained below, we affirm the district court’s dismissal with prejudice of the conversion and unfair trade practices claims. We conclude, however, that the court should have dismissed the contract, negligence, and fraud claims as preempted by the FLSA. Accordingly, we vacate the court’s alternative dispositions of those claims — the dismissal with prejudice of the fraud claim and the summary judgment awards on the contract and negligence claims — and remand with instructions to dismiss the claims without prejudice, giving the Class Members an opportunity to pursue any FLSA claims they may possess.
I.
A.
It is undisputed that, until early April 2003, Sara Lee enforced a so-called “Dress and Undress Rule” for hourly production workers at its Tarboro bakery, which makes cheesecakes, layer cakes, pastries, muffins, and other perishable goods. During the time period relevant to this civil action, the total number of Tarboro рroduction workers at a given time varied between approximately 950 (the average number in 2000) and 650 (the average in the first part of 2003). These workers were divided into two shifts. Under the Dress and Undress Rule, they were required to wear a uniform consisting of the following: a shirt and pants (with a worker-provided belt), or an optional dress for women; a set of earplugs; a hairnet; and a pair of safety shoes. The shirts and dresses were personalized with the workers’ names, and the uniforms, except the shoes, were washed and then sorted by employee number on a rotating conveyor in an on-site laundry room. The shoes were stored in personal lockers in men’s and women’s locker rooms.
To comply with the Dress and Undress Rule, production workers were to arrive at the bakery in street clothes, pass through security, walk to the laundry room, wait in line with their shiftmates, obtain their uniforms at the laundry room window from the lone attendant on duty (or occasionally retrieve their uniforms themselves), walk to the appropriate locker room, wait for space to change clothes, change into their uniforms, place their street clothes in their lockers, walk to a hand washing and foot bath area, wash and sanitize their hands and shoes, and walk to the time clock inside the production area — all before clocking in and taking their places on the production line. At the end of the shift, the workers clocked out, then walked back to the locker room, changed into their street clothes, walked to the laundry room, and deposited their soiled uniforms into a bin before leaving the bakery.
While the Dress and Undress Rule was in effect, the production workers had to worry about committing two types of infractions. First, workers who failed to comply with the Dress and Undress Rule were prohibited from working the shift. Second, workers who clocked in late because of delays in the clothes-changing process were deemed tardy; those who accumulated twenty citations for tardiness in a twelve-month period were discharged. The Dress and Undress Rule was revised in early April 2003 to allow workers to don their uniforms (except their safety shoes) at home.
B.
The Class Action Complaint was filed in January 2003 in the Superior Court of Edgecombe County, North Carolina, on behalf of current and former hourly production workers at the Tarboro bakery who were subject to the Dress and Undress Rule and entitled to FLSA protec *184 tions. 1 It alleges that, by failing to compensate workers for time spent complying with the Dress and Undress Rule, Sara Lee violated the “applicable wage and hour law,” i.e., thе FLSA. See Class Action Complaint ¶ 48. The Complaint does not, however, plead claims directly under the FLSA. Rather, it pleads five separate claims under North Carolina law for breach of contract, negligence, fraud, conversion, and unfair trade practices in contravention of the North Carolina Unfair and Deceptive Trade Practices Act, N.C. Gen.Stat. § 75-1.1 (the “UDTPA”). The Complaint seeks recovery of, inter alia: compensatory damages, including back pay; penalties and interest; punitive damages; and, with respect to the unfair trade practices claim, treble damages and attorneys’ fees pursuant to the UDTPA. The Class Members maintain that they are entitled to damages for the period from January 27, 2000, through April 1, 2003 (when the Dress and Undress Policy was revised).
On February 26, 2003, Sara Lee removed this action, under 28 U.S.C. § 1441, to the Eastern District of North Carolina. 2 Shortly thereafter, on March 3, 2003, Sara Lee made its motion, under Federal Rule of Civil Procedure 12(b)(6), to dismiss the Class Action Complaint for failure to state a claim upon which relief can be granted. In support of the Rule 12(b)(6) motion, Sara Lee maintained that the FLSA preempted each of the Class Members’ state claims and that, apart from being preempted, the claims were not cognizable. By its Dismissal Order of April 14, 2003, the district court rejected Sara Lee’s preemption contention. 3 The court agreed, however, that the Complaint fails to state colorable claims for fraud, conversion, and unfair trade practices, and it therefore dismissed those three claims with prejudice. Finally, the court refused to dismiss the contract and negligence claims, based on its determination that those two claims were sufficiently pleadеd in the Complaint. Significantly, the court recognized that the contract and negligence claims were predicated on violations of the FLSA, and that their ultimate success thus depended on a showing that the FLSA required Sara Lee to compensate its workers for time spent complying with the Dress and Undress Rule.
Thereafter, the parties engaged in discovery and stipulated to the certification of a class on the contract and negligence claims. On June 1, 2004, Sara Lee filed its motion, under Federal Rule of Civil Procedure 56, for summary judgment. In its supporting memorandum, Sara Lee reiterated its position that the contract and neg *185 ligence claims are preempted by the FLSA. Additionally, Sara Lee contended that those claims must nonetheless fail, because the FLSA (on which they were predicated) did not require paying workers for comрliance with the Dress and Undress Rule. Specifically, Sara Lee asserted that time spent complying with the Rule was noncompensable, pursuant to the Portal-to-Portal Act, 29 U.S.C. §§ 251-262 (excluding from FLSA compensability, in § 254(a), certain functions that are “preliminary” or “postliminary” to employees’ “principal” work activities). Alternatively, Sara Lee recognized that, generally speaking, time spent by employees on the isolated act of changing clothes might be com-pensable under the FLSA, but that the time spent by the Class Members changing clothes was yet noncompensable because it was “de minimis.”
On its de minimis point, Sara Lee acknowledged that the Class Members had forecast evidence, by way of the deposition testimony of the named plaintiffs, showing that “a single clothes change took as much as 20 minutes,” J.A. 102, and that workers thus spent a total of “30-40 minutеs a day on clothes-changing time alone,” id. at 112. In discussing the Class Members’ evidence, Sara Lee referred to excerpts from the named plaintiffs’ deposition transcripts, which Sara Lee had attached to its summary judgment memorandum. See id. at 165-66 (testimony of David C. Anderson that it took him about fifteen minutes for pre-shift clothing change and fifteen minutes for all post-shift activities, including clothing change); id. at 181-83 (testimony of Samuel Pullen that pre- and post-shift clothing changes each took him fourteen to twenty minutes). Sara Lee characterized this testimony as “grossly exaggerated” and “patently outrageous,” but conceded that it had to be accepted as true at the summary judgment stage of the proceedings. Id. at 102, 112.
Nevertheless, Sara Lee urged the court, in considering the de minimis issue, to ignore the actual time it took workers to change clothes (as establishеd by the named plaintiffs’ testimony) and to instead look at “the time that should reasonably have been required for changing clothes.” J.A. 103. In this regard, Sara Lee presented a study conducted by its expert, who measured and averaged the time taken by nine management employees — playing-the part of hourly production workers — to engage in the clothes-changing process during a Saturday production shutdown. The time study concluded that the pre- and post-shift clothing changes for workers assigned the more-complicated pants uniform (with its shirt, pants, and belt) took an average of 3.12 minutes. The study further indicated that these workers needed just 7.33 minutes to complete pre-shift activities from donning their uniforms to clocking in, as well as post-shift activities from clocking out through changing back into their street clothes. The study did not address the time spent on activities ocсurring before and after the clothing changes, including standing in line at the laundry room window, obtaining uniforms from the attendant on duty, and depositing soiled uniforms into the laundry bin.
The Class Members filed a memorandum in opposition to the summary judgment motion, in which they contended that they were entitled to compensation for time spent on all of the activities encompassed in the Dress and Undress Rule. In support of their assertion that this time amounted to as much as sixty minutes per day (including forty-five minutes for pre-shift activities), they attached affidavits executed by sixty-seven separate hourly production workers. These affidavits used the same fill-in-the-blank form, and had not previously been provided to Sara Lee in discovery. The Class Members also *186 attached excerpts of certain deposition transcripts, but not the excerpts from the named plaintiffs’ deposition transcripts already discussed and submitted to the court by Sara Lee. The Class Members explained in their opposition memorandum that, because 200 to 300 employees sometimes arrived at the bakery within fifteen minutes of each other, there were often long waits at the laundry room window, in the locker rooms, at the hand washing and foot bath area, and at the time clock. Moreover, in anticipation of possible gridlock during the clothes-changing process, workers were compelled to arrive at the bakery as much as forty-five minutes before the start of their scheduled shifts in order to avoid tardiness citations.
As part of their opposition memorandum, the Class Members requested the court to exclude, pursuant to Federal Rule of Evidence 702, the time study prepared by Sara Lee’s expert. The Class Members contended that the study — which reached its conclusions by measuring and averaging the time taken by nine management employees to go through the clothes-changing process during a Saturday production shutdown — failed to “adequately replicate[ ] the situation facing the [hourly production workers] when they are required to comply with [the Dress and Undress Rule] in the real work-a-day world.” J.A. 256.
In reply to the Class Members’ opposition memorandum, Sara Lee moved to strike the Class Members’ sixty-seven worker affidavits on various grounds, including the failure to produce the affidavits during discovery. The Class Members did not respond to Sara Lee’s motion to strike.
By its Summary Judgment Order of December 7, 2004, the district court granted Sara Lee’s motion to strike the sixty-seven worker affidavits, limited the admissibility of its expert time study, and granted its motion for summary judgment on the contract and negligence claims. 4 With respect to the sixty-seven worker affidavits, the court concluded that exclusion of the affidavits was an appropriate sanction for the Class Members’ noncompliance with discovery deadlines. As for Sara Lee’s expert time study, the court expressed agreement with the Class Members that the study failed to replicate the conditions that sometimes protracted the clothes-changing process. Even so, the court declined to wholly exclude the study, instead admitting it on a limited basis, apparently for the purpose of estimating the time needed by workers for the isolated acts of changing clothes and washing and sanitizing their hands and safety shoes (the “changing-and-washing activities”).
Finally, with respect to the contract and negligence claims, the court again recognized that their viability depended on establishing that Sara Lee was mandated by the FLSA to cоmpensate the hourly production workers for time spent complying with the Dress and Undress Rule. The court determined that the Portal-to-Portal Act excluded from FLSA compensability all Rule-related activities, except perhaps the changing-and-washing activities. The court further decided that those activities could not be compensable, however, if it took a de minimis amount of time to perform them. See Summary Judgment Order 26 (recognizing “general rule ... that ten minutes or less of uncompensated time will be de minimis as a matter of law”). And, the court adopted Sara Lee’s reasonableness standard for the de minimis inquiry, ruling that the pertinent question was “how much time employees would reasonably spend donning and doffing their *187 uniforms and walking through the foot-bath.” Id. at 28 (emphasis added).
The evidence before the court on this issue was the named plaintiffs’ deposition testimony and Sara Lee’s expert time study. The court noted that, because the Class Members were еntitled to have the evidence viewed in their favor, it gave the time study “minimal, if any, weight.” Summary Judgment Order 29. Nonetheless, the court ignored the named plaintiffs’ deposition testimony— relevant excerpts of which were attached to and discussed in Sara Lee’s summary judgment memorandum — establishing that clothes-ehanging time alone was as much as thirty to forty minutes per day. And, because the Class Members had focused their arguments and evidence on the amount of time it took to fully comply with the Dress and Undress Rule, the court was left with no evidence showing that the particular time spent on the changing-and-washing activities was more than de minimis. Accordingly, the court awarded summary judgment to Sara Lee on the contract and negligence claims. The court then entered its final judgment on that same day (December 7, 2004).
On December 21, 2004, the Class Members filed a post-judgment motion, under Fedеral Rules of Civil Procedure 59(e) and 60(b), for reconsideration of the Summary Judgment Order. By its Order of February 8, 2005, the court denied the Class Members’ motion for reconsideration.
C.
The Class Members have timely appealed from both the final judgment and the denial of reconsideration, and we possess jurisdiction pursuant to 28 U.S.C. § 1291. 5 On appeal, the Class Members challenge the dismissal of their fraud, conversion, and unfair trade practices claims; the exclusion of the sixty-seven worker affidavits; the admission of Sara Lee’s expert time study; and the award of summary judgment against them on their contract and negligence claims. In response, Sara Lee defends the district court’s dismissal, evidentiary, and summary judgment rulings, but also asserts that the court should have deemed all of the Class Members’ claims to be preempted by the FLSA.
We first address the dismissal with prejudice of the Class Members’ fraud, conversion, and unfair trade practices claims. Although we agree with the district court’s conclusion that the Class Members failed to state claims for conversion and unfair trade practices upon which relief can be granted, we disagree with its determination that the fraud claim is similarly deficient. We then turn to the issue of whether the remaining claims — for fraud, as well as breach of contract and negligence — are preempted by the FLSA. We conclude that they are so preempted. Accordingly, we affirm the dismissal with prejudice of the conversion and unfair trade practices claims, vacate the dismissal with prejudice of the fraud claim and the summary judgment awards on the contract and negligence claims, and remand with instructions to dismiss without prejudice the contract, negligence, and fraud claims as preempted by the FLSA. 6
*188 II.
We first considеr whether the district court properly dismissed, pursuant to Federal Rule of Civil Procedure 12(b)(6), the Class Members’ fraud, conversion, and unfair trade practices claims for failure to state a claim upon which relief can be granted. When a district court grants a Rule 12(b)(6) motion, we review its decision de novo.
See Bominflot, Inc. v. The M/V Henrich S,
In assessing the sufficiency of the claims alleged in the Class Action Complaint, the district court characterized “[t]he predicate act at issue in this litigation” — Sara Lee’s failure to compensate production workers for time spent complying with the Dress and Undress Rule — as one “based on an interpretation or misinterpretation of’ the FLSA. Dismissal Order 12. The court concluded that any misinterpretation of the FLSA was necessarily negligent, and not intentional. Accordingly, the court dismissed the fraud and conversion claims, because they each require a showing of wrongful intent. See id. at 10-11 (ruling that Complaint fails to allege intent to deceive, one element of fraud claim under North Carolina law); id. at 11-12 (concluding that Complaint fails to allege requisite intentional act in support of state law conversion claim). The court also dismissed the unfair trade practices claim, based on its determination that an intentional breach of contract — had one been *189 alleged in the Complaint — “does not rise to the level of a deceptive or unfair business practice.” Id. at 14.
A.
We disagree with the district court’s ruling on the fraud claim. Under North Carolina law, the elements of actual fraud are “(1) [fjalse representation or concealment of a material fact, (2) reasonably calculated to deceive, (3) made with intent to deceive, (4) which does in fact deceive, (5) resulting in damage to the injured party.”
Forbis v. Neal,
Simply put, the allegations of the Class Action Complaint are sufficient to state a claim for fraud under North Carolina law, even under the heightened pleading standard for fraud claims imposed by Rule 9(b). Moreover, although the evidence may ultimately show that any violation of the FLSA by Sara Lee was unintentional, we cannot agree with the district court’s determination, at the Rule 12(b)(6) stage of the proceedings, that this was necessarily so.
Cf. IntraComm, Inc. v. Bajaj,
*190 B.
We nonetheless affirm the district court’s dismissal of the conversion and unfair trade practices claims. As Sara Lee correctly asserts, the Supreme Court of North Carolina has not recognized causes of action for conversion or unfair trade practices in employer-employee disputes over unpaid wages such as this one, and there is no basis for concluding that it would do so if given the opportunity, including any decisions of the state’s intermediate appellate court that might be persuasive.
See Food Lion, Inc. v. Capital Cities/ABC, Inc.,
The Class Members essentially concede on appeal that the facts alleged do not constitute conversion, which has long been defined by the Supreme Court of North Carolina as “an unauthorized assumption and exercise of the right of ownership over goods or personal chattels belonging to another, to the alteration of their condition or the exclusion of an owner’s rights.”
Peed v. Burleson’s, Inc.,
III.
We turn now to the issue of whether the Class Members’ remaining claims — for breach of contract, negligence, and fraud— are preempted by the FLSA. The district court decided that those three claims are not so preempted. This issue constitutes a question of law that we review de novo.
See Cox v. Shalala,
A.
We are guided by longstanding principles of preemption in our assessment of whether the FLSA invalidates the Class Members’ remaining claims. The Supremacy Clause of the Constitution renders federal law “the supreme Law of the Land ... any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.” U.S. Const. art. VI, cl. 2. “As a result, federal statutes and regulations properly enacted and promulgated can nullify conflicting state or local actions.”
College Loan Corp. v. SLM Corp.,
In assessing whether an actual conflict exists between state and federal law, “we resolve the more specific inquiries of whether ‘it is impossible to comply with both state and federal law1 or ‘whether the state law stands as an obstacle to the
*192
accomplishment of the full purposes and objectives’ of federal law.”
Worm v. Am. Cyanamid Co.,
Of course, our preemption inquiry must “ ‘start [ ] with the basic assumption that Congress did not intend to displace state law.’ ”
S. Blasting,
B.
With the above-stated legal principles in mind, we proceed with our assessment of Sara Lee’s contention, under a theory of conflict preemption (or, more specifically, obstacle preemption), that the FLSA displaces the Class Members’ contract, negligence, and fraud claims. Of significance to our inquiry, Congress enacted the FLSA to eliminate “labor conditions detrimental to the maintenance of the minimum standard of living necessary for health, efficiency, and general well-being of workers.” 29 U.S.C. § 202(a). The FLSA mandates that covered workers be paid a minimum wage, see id. § 206, and that they receive overtime compensation, see id. § 207.
As we have recognized, “the FLSA provides an unusually elaborate enforcement scheme.”
Kendall v. City of Chesapeake,
By contrast, the Class Members’ claims for breach of contract, negligence, and fraud come with remedies that, in some respects, are more generous than those *193 provided in the FLSA enforcement scheme. For example, the contract claim (even without proof of a willful failure to pay wages due) is arguably subject to a three-year limitations period, see N.C. Gen.Stat. § 1-52(1), and punitive damages may be awarded in North Carolina upon proof of fraud, malice, or willful or wanton conduct, see id. § 1D-15(a). Crucially, though, the Class Members’ state claims all depend on establishing that Sara Lee violated the FLSA, either in good faith or willfully. See, e.g., Class Action Complaint ¶ 31 (alleging, as part of negligence claim, that Sara Lee “carelessly” failed to pay Class Members wages due under FLSA); id. ¶¶ 38, 41 (asserting, as part of contract claim, that Sara Lee breached promise to pay FLSA-mandated wages); id. ¶ 51 (alleging, as part of fraud claim, that Sara Lee “willfully failed and refused to pay ... Class Members for compensable time” under FLSA). Without doubt, these state claims essentially require the same proof as claims asserted under the FLSA itself. 11
The issue before us is whether, in these circumstances, the Class Members’ FLSA-based state claims “stand[ ] as an obstacle to the accomplishment of the full purposes and objectives of’ the FLSA.
Worm,
The Class Members do not contend, however, that any North Carolina law entitles them to unpaid wages. Rather, as discussed above, they rely on the FLSA for their rights, and they invoke state law only as the source of remedies for the alleged FLSA violations. Importantly, the FLSA does not explicitly authorize states to create alternative remedies for FLSA violations. And, in view of the FLSA’s unusually elaborate enforcement scheme, there cannot be the exceptionally strong presumption against preemption of such state remedies that would be warranted if the FLSA did not provide federal remedies.
See Abbot,
Whether the FLSA provides exclusive remedies for the enforcement of its own provisions is a question that need not occupy us for long, because we already answered it in
Kendall.
There, we were called on to decide whether the plaintiffs could use 42 U.S.C. § 1983 to enforce then-rights to overtime compensation under the FLSA.
Kendall,
In accordance with our ruling in
Kendall,
we must hold today that Congress prescribed exclusive remedies in the FLSA for violations of its mandates. And we note that we are not alone in so concluding.
See Roman v. Maietta Constr., Inc.,
Beсause the FLSA’s enforcement scheme is an exclusive one, we further conclude that the Class Members’ FLSA-based contract, negligence, and fraud claims are precluded under a theory of obstacle preemption. Our conclusion is consistent with the rulings of several district courts deeming state claims to be preempted by the FLSA where those claims have merely duplicated FLSA claims.
See, e.g., Choimbol v. Fairfield Resorts, Inc.,
No. 2:05cv463,
Finally, although Sara Lee presents FLSA preemption as a ground for affirming the final judgment rendered by the district court in its favor, we deem it more appropriate to remand the contract, negligence, and fraud claims for dismissal without prejudice as preempted by the FLSA. This will give the Class Members an opportunity to pursue any FLSA claims they may possess.
Cf. Pueschel v. United States,
IV.
Pursuant to the foregoing, we affirm the Rule 12(b)(6) dismissals with prejudice of the conversion and unfair trade practices claims. We vacate the Rule 12(b)(6) dismissal with prejudice of the fraud claim, as well as the Rule 56 summary judgment awards on the contract and negligence claims, and remand with instructions to dismiss without prejudice those three claims as preempted by the FLSA.

In addition to defending the district court's dismissals of the Class Members' fraud, conversion, and unfair trade practices claims, Sara Lee contends on appeal that the court could have dismissed the claims for breach of contract and negligence under Rule 12(b)(6), rather than waiting to render its Rule 56 summary judgment award on those two claims.
