Most people think of currency seizures as something that happens at airports — a traveler gets pulled aside at the gate, CBP finds cash that was not declared, and the enforcement process begins. That mental model is accurate for the majority of currency seizures by volume. But it misses a growing category of enforcement action that operates differently, involves different legal frameworks, affects different types of people, and produces different — and in some ways harder — litigation dynamics.
Domestic carrier seizures — cash found by law enforcement or federal agents inside FedEx, UPS, DHL, or USPS packages — are a distinct enforcement problem with their own procedural rules, their own evidentiary challenges, and their own set of defenses. They are also increasing. As airport seizure rates climb and interdiction technology improves, people attempting to move cash illicitly have increasingly turned to the parcel carrier network. But legitimate cash shipments — businesses with banking access problems, estate distributions, certain types of commercial transactions — also move through parcel carriers for entirely lawful reasons. When those packages get seized, the owners face a legal process that is in several respects more difficult than a standard airport seizure case.
Great Lakes Customs Law handles domestic carrier seizure cases through our domestic cash seizure practice. This article explains how these cases differ from airport seizures, what legal frameworks apply, and what the realistic options are for someone whose cash has been seized from a parcel carrier shipment.
How Carrier Seizures Happen
FedEx, UPS, DHL, and the U.S. Postal Service are all subject to federal law enforcement interdiction programs targeting bulk cash, narcotics, and other contraband moving through the parcel network. The enforcement mechanisms differ by carrier type.
For private carriers — FedEx, UPS, DHL — law enforcement typically operates through two pathways. The first is a consent-based inspection where the carrier’s employees flag a suspicious package and alert law enforcement, who then ask for consent to open and inspect. The second is a court-authorized search warrant based on probable cause developed through package profiling — characteristics like the origin ZIP code, the destination pattern, the declared contents, the weight relative to the declared value, and whether the package was paid for in cash at the counter. Law enforcement has developed sophisticated profiling criteria for identifying packages likely to contain cash or narcotics, and those criteria generate a significant volume of warrant applications at major distribution hubs.
For USPS packages, the Fourth Amendment analysis is more complex. Mail enjoys stronger constitutional protections than private carrier packages — law enforcement generally cannot open a sealed domestic mail package without a warrant, though there is established case law permitting external examination, use of drug-detection dogs on mail, and interception of packages sent to or from known addresses of interest. The USPS Postal Inspection Service has its own interdiction program that operates parallel to DEA, IRS CI, and local law enforcement task forces.
When cash is found — whether through a consent search, a warrant, or a controlled delivery — the package is typically seized and the contents retained as evidence or for civil forfeiture. The carrier is not held liable for the contents. The legal action runs against the currency itself, the shipper, the intended recipient, or both — depending on the theory of forfeiture the government pursues.
How Carrier Seizures Differ From Airport Seizures
The differences between airport currency seizures and domestic carrier seizures are significant at every stage of the process — from the legal authority for the seizure, to the procedural framework that governs what happens next, to the practical dynamics of making a claim and litigating one.
The legal authority is different. Airport seizures of currency for failure to report are made under the Bank Secrecy Act — specifically 31 USC §§ 5316 and 5317 — which creates the reporting requirement and the civil forfeiture authority for violations of it. Domestic carrier seizures of cash typically do not involve a Bank Secrecy Act reporting violation, because there is no reporting requirement for shipping cash domestically through a parcel carrier. Instead, these seizures are almost always made under the civil asset forfeiture authority of 18 USC § 981 — the general federal civil forfeiture statute — or under 21 USC § 881, the drug-related forfeiture statute. The theory is not that the owner failed to report the currency. The theory is that the currency is the proceeds of drug trafficking or another specified unlawful activity, or that it was used or intended to be used to facilitate such activity.
The government’s burden is different. In an airport failure-to-report case, the government’s burden in the civil forfeiture is relatively light — it must establish that the currency was transported across the border without the required report, which is established by the seizure itself. The owner then bears the burden of establishing an innocent owner defense under CAFRA. In a domestic carrier seizure case, the government typically must establish probable cause to believe the currency is connected to drug trafficking or another specified unlawful activity. That requires more than just finding cash in a box. The government must point to additional indicators — the shipping origin, the packaging characteristics, the presence of drug odor detected by a canine, the financial profile of the shipper or recipient, or other circumstantial evidence — to establish the probable cause nexus to criminal activity.
CAFRA applies — and that matters. Domestic carrier seizures of cash by federal agencies are almost always governed by the Civil Asset Forfeiture Reform Act of 2000 (CAFRA), codified at 18 USC § 983. Unlike the non-CAFRA framework that governs many CBP customs seizures, CAFRA provides meaningful procedural protections: the government must send written notice within 60 days of the seizure; the claimant has 35 days from personal notice to file a claim; no cost bond is required to file a judicial claim; and the claimant has a statutory innocent owner defense under 18 USC § 983(d). These protections are significantly more favorable than the non-CAFRA framework, and understanding that they apply is the starting point for an effective defense in a carrier seizure case.
There is no FinCEN 105 violation to mitigate. In an airport seizure, the petition process through CBP’s FP&F office is the primary administrative remedy — and the mitigation framework, however imperfect, provides a structured path to partial or full return of seized currency. In a domestic carrier seizure, there is no equivalent administrative petition pathway through CBP, because CBP is typically not the seizing agency. The case goes directly into the federal civil forfeiture process, where the claimant must file a claim and litigate the forfeiture in federal district court — or negotiate a settlement with the U.S. Attorney’s Office — without a separate administrative mitigation stage.
The Intervening Ownership Problem
One of the most legally complex aspects of domestic carrier seizures is what practitioners call the intervening ownership problem — the question of who actually has standing to contest the forfeiture when cash moves through a parcel carrier.
In an airport seizure, the ownership situation is usually straightforward: the traveler had the cash on their person, CBP seized it from them directly, and the traveler is the obvious claimant. In a carrier seizure, the cash was in a package that passed through the hands of a shipping company, was handled by multiple employees at distribution facilities, and may have been intercepted at a location far from both the sender and the intended recipient. The shipper and the recipient may be different people or entities. Either — or both — may have a cognizable interest in the currency. And the government may have theories against both.
Under CAFRA, an “owner” for purposes of the innocent owner defense includes any person with ownership, dominion, or control over the property at the time it was seized. That is broad enough to encompass both the shipper and the intended recipient in most cases. But filing a claim requires asserting an interest in the property — and asserting that interest puts the claimant on the government’s radar as someone connected to the seized currency. In cases where the government’s forfeiture theory is drug-related, the decision to file a claim involves a careful assessment of the claimant’s exposure to criminal investigation as well as civil forfeiture.
The intervening ownership issue also arises when cash is sent by one party on behalf of another — a business owner shipping cash receipts to a main office, an individual sending money to a family member, or a community organization distributing collected funds. In these situations, the beneficial owner of the currency may be different from the person whose name is on the shipping label. Establishing ownership and innocent owner status requires tracing the currency from its source through the shipping transaction to the seizure — a documentary chain that legitimate cash shipments can usually establish and that illegitimate ones cannot.
The Drug Odor Problem — and Its Limits
In the vast majority of domestic carrier seizure cases we handle, the government’s probable cause narrative includes a reference to a drug-detection dog alerting to the package. This is the government’s most common tool for establishing the nexus between seized currency and drug trafficking, and it is also one of the most contested evidentiary issues in civil forfeiture litigation.
The legal theory behind the canine alert is straightforward: drug-detection dogs are trained to identify the odor of controlled substances, and an alert to a package containing currency is argued to suggest that the currency was previously in contact with narcotics — evidence that it is drug proceeds. Courts have generally accepted canine alerts as contributing to probable cause, though not as independently sufficient probable cause in all circuits.
The problem with this theory — and it is a well-documented one — is that a significant percentage of U.S. currency in general circulation carries detectable trace amounts of controlled substances, particularly cocaine, as a result of widespread handling and contamination through ATM machines, cash drawers, and wallet-to-wallet transfer. Studies have consistently found that a substantial majority of U.S. paper currency bears cocaine residue at levels sufficient to trigger a trained drug detection dog. This means a canine alert to a package containing currency does not necessarily tell us anything about whether that specific currency was involved in drug transactions — only that it is U.S. currency that has been in circulation.
Courts have grappled with this problem differently. In some circuits, a canine alert combined with other circumstantial factors — origin ZIP code associated with drug source cities, packaging characteristics, shipping profile, recipient characteristics — is sufficient for probable cause. In others, courts have required more specific evidence connecting the currency to drug activity before the government can prevail. The strength of the canine alert argument depends heavily on the circuit, the additional evidence available, and the specific facts of the shipment. An experienced attorney will evaluate the government’s probable cause package critically and challenge it where the evidence is thin.
Disposition Timing — The 60-Day Clock and What Happens Next
Under CAFRA, the seizing agency must send written notice to interested parties within 60 days of the seizure. This is one of CAFRA’s most important protections — it prevents the government from sitting on seized assets indefinitely while the owner has no idea what is happening or what their options are. If the government fails to send notice within the 60-day window, the claimant may have grounds to challenge the forfeiture on due process grounds.
Once notice is sent, the claimant has 35 days from the date of the personal notice letter to file a claim with the seizing agency — typically the DEA, FBI, IRS Criminal Investigation, or Postal Inspection Service depending on which agency made the seizure. Filing the claim triggers the government’s obligation to either return the property or file a civil forfeiture complaint in federal district court within 90 days. If the government does not file a complaint within that window, the claimant can move to dismiss the forfeiture and recover the seized currency.
This sequence — 60-day notice, 35-day claim window, 90-day complaint deadline — creates a defined litigation timeline that is more structured than the customs administrative process. It also creates specific procedural deadlines for the government that can be enforced. A claimant represented by counsel who tracks these deadlines precisely is in a position to hold the government accountable in ways that a self-represented claimant typically is not.
After the complaint is filed, the case proceeds as a civil in rem forfeiture action — styled as something like United States v. $47,500 in United States Currency — in federal district court. The claimant files an answer, discovery proceeds, and the case either settles or goes to trial. The government bears the burden of proving by a preponderance of the evidence that the currency is subject to forfeiture. The claimant has the opportunity to present the innocent owner defense — establishing by a preponderance that they did not know the currency was connected to any illegal activity, or that upon learning of the connection they took all reasonable steps to stop it.
Who Sends Cash Through Parcel Carriers — and Why
Understanding who legitimately ships cash through FedEx, UPS, and DHL is important context for evaluating the government’s drug trafficking narrative and building the innocent owner defense.
Cannabis-related businesses operating legally under state law but unable to access federal banking services are among the most common legitimate shippers of large cash amounts through parcel carriers. Because federal law still classifies cannabis as a controlled substance, federally insured banks cannot serve cannabis businesses without risk to their charters — leaving legal cannabis operators to handle revenue in cash and move it through whatever channels are available. This creates a factually complicated situation: the cash is legal state business revenue, but it is revenue from an activity that remains federally illegal, which gives the government a colorable forfeiture theory even against legitimate cannabis operators.
Small businesses with limited or no banking access — a persistent problem in certain immigrant communities and in rural areas underserved by traditional banks — also legitimately ship cash for business purposes. A restaurant operator who banks by depositing cash with a main office across the country, a market vendor who sends weekly receipts to a business partner, or a family business distributing cash to multiple locations may all have entirely legitimate reasons for shipping currency through a parcel carrier.
Estate distributions involving physical currency — cash held by a deceased family member that is being distributed among heirs — are another category. Families who discover cash savings that were never deposited in any financial institution may have no practical way to distribute the money other than physically sending it.
In each of these situations, the existence of a legitimate explanation for the cash is the foundation of the innocent owner defense. The documentation required to prove that explanation — business records, tax filings, estate documents, family financial records — is the same documentation required to defeat the government’s drug trafficking narrative. Building that documentary record, quickly and completely, is the most important early task in a domestic carrier seizure case.
The Settlement Option — and When It Makes Sense
Most domestic carrier forfeiture cases do not go to trial. They resolve through negotiated settlements with the U.S. Attorney’s Office handling the forfeiture. The settlement process is informal — there is no equivalent to CBP’s published mitigation guidelines — and outcomes depend heavily on the strength of the government’s probable cause evidence, the quality of the claimant’s innocent owner documentation, and the U.S. Attorney’s assessment of how the case would fare at trial.
In cases with strong innocent owner documentation and weak government probable cause — a canine alert with no other indicators, currency from a legal business with complete records — settlements returning 70 to 100 percent of the seized amount are achievable. In cases where the government has stronger evidence — drug packaging materials, communications referencing drug transactions, a shipping profile that closely matches known trafficking patterns — the settlement range is lower, and the decision whether to litigate rather than settle requires a careful cost-benefit analysis.
The settlement negotiation is not a petition process. It is a direct negotiation with a federal prosecutor who has discretion over whether to return the money, pursue the forfeiture, or offer a compromise. The leverage in that negotiation comes from the quality of the claimant’s documentation, the credibility of the innocent owner narrative, and the attorney’s ability to identify and articulate weaknesses in the government’s probable cause case. Approaching that negotiation without experienced representation is a significant disadvantage.
What to Do If Your Cash Was Seized From a Parcel Carrier
If you have received notice that cash shipped through FedEx, UPS, DHL, or USPS has been seized by a federal agency, the most important immediate steps are straightforward but time-sensitive.
First, note the date on the notice letter carefully. The 35-day claim deadline runs from the date of the personal notice, not from when you received it. If the letter was delayed in the mail or sent to an address that required forwarding, you may have less time than you think. Do not wait.
Second, begin gathering documentation of the source and purpose of the cash immediately. Bank records, business records, tax returns, estate documents, or whatever records establish where the money came from and what it was intended for. The sooner this documentation is assembled, the better positioned the case will be — both for the claim filing and for the subsequent settlement negotiation or litigation.
Third, do not contact the seizing agency or the U.S. Attorney’s Office directly without legal representation. Statements made during the administrative or pre-litigation stage become part of the record and can be used against you. The innocent owner defense requires presenting a clear, consistent, and fully documented narrative — not an off-the-cuff explanation to a federal agent who is building a forfeiture case against your property.
Great Lakes Customs Law handles domestic carrier seizure cases alongside our currency seizure practice. These cases are procedurally distinct from airport seizures and require a different approach — but the core principle is the same: the outcome depends on how well the legitimate origin and purpose of the currency is documented and presented, and on how aggressively the government’s probable cause narrative is challenged.
