Most people associate CBP currency seizures with international travel — cash seized at an airport customs checkpoint or a land border crossing. But federal law enforcement agencies, including CBP and Homeland Security Investigations (HSI), also seize cash from travelers on domestic flights and from packages shipped through carriers like UPS, FedEx, DHL, and USPS. These domestic seizures operate under different legal authority than international currency reporting violations, but the process for contesting them and recovering your money follows a similar framework.
Domestic Flight Cash Seizures
There is no reporting requirement for cash when traveling within the United States. Carrying any amount of cash on a domestic flight is legal. However, TSA agents who observe large amounts of cash during baggage screening are trained to alert law enforcement — typically DEA agents or local police assigned to the airport — who may then seize the money under civil asset forfeiture authority.
It is important to understand who actually seizes your money on a domestic flight. In most domestic airport seizures, the seizing agency is not CBP — it is the DEA, a local law enforcement agency, or a joint task force operating under federal or state civil forfeiture law. The agency that seized the money determines which forfeiture process applies and where your petition or claim must be filed. Misidentifying the seizing agency and filing with the wrong office is a common mistake that can cost you your response deadline.
When CBP or HSI is involved in a domestic seizure — which does occur, particularly at airports with active HSI presence — the forfeiture proceeds under federal law, typically 18 USC 981, which authorizes civil forfeiture of property involved in or traceable to money laundering and other specified unlawful activity. The government does not need to charge you with a crime to pursue forfeiture under this statute. It needs only to establish by a preponderance of the evidence that the money is connected to unlawful activity.
What Triggers a Domestic Cash Seizure
Law enforcement looks for a combination of factors when deciding whether to seize cash at a domestic airport. No single factor is determinative, but common triggers include:
- Large amount of cash discovered during TSA screening, particularly if rubber-banded, vacuum-sealed, or bundled in a way associated with drug proceeds
- One-way ticket purchased with cash shortly before departure
- Travel on a route known for drug trafficking
- Nervousness or inconsistent answers when questioned by officers
- Presence of drug odor on the cash or luggage, detected by a canine unit
- Prior criminal record, particularly drug-related convictions
- Inability to explain the source of the funds or the purpose of travel
None of these factors makes a seizure legally valid on its own, and many have been successfully challenged in court. A drug dog alert, for example, is not sufficient standing alone to establish that money is drug proceeds — studies have shown that a significant percentage of U.S. currency in circulation tests positive for drug residue simply from ordinary handling.
Cash Seized from UPS, FedEx, DHL, and USPS Packages
Shipping cash through a commercial carrier or the postal service is legal but carries significant risk of seizure. CBP, HSI, DEA, and postal inspectors actively monitor parcel shipments for cash and other contraband, and packages flagged for inspection can be opened and the contents seized without a warrant under certain circumstances.
How Packages Get Flagged
Carrier packages are flagged for law enforcement inspection through several channels:
- Carrier employee tips. UPS, FedEx, and DHL employees are trained to identify suspicious packages and are legally permitted to alert law enforcement. Packages that feel like cash, have unusual weight distribution, or are shipped from known drug source cities may be flagged this way.
- Canine units at carrier facilities. DEA and other agencies operate drug detection canines at major carrier sorting facilities. A positive alert on a package can provide the legal basis for opening it.
- X-ray screening. Packages at major distribution hubs are often screened by X-ray. Dense rectangular objects consistent with bundled currency can trigger a manual inspection.
- Pattern analysis. Packages shipped from certain zip codes, to certain destinations, in certain quantities, or with certain packaging characteristics can be flagged by algorithmic screening systems.
- Recipient or sender history. If either party to the shipment has a prior law enforcement history, packages between them may be subject to heightened scrutiny.
What Happens After a Package Is Seized
When law enforcement opens a package and finds cash, the money is typically seized immediately and a notice is left at the delivery address or mailed to the sender. Depending on which agency conducted the seizure, the forfeiture process will be administered by that agency — DEA, CBP, HSI, or the U.S. Postal Inspection Service each have their own forfeiture procedures.
As with international seizures, you will receive a notice of seizure identifying the amount seized, the legal authority cited, and your options for contesting the forfeiture. Response deadlines are strict — typically 30 to 35 days from the date of the notice — and missing the deadline results in administrative forfeiture with no further opportunity to contest.
The Legal Framework: How Domestic Forfeiture Works
Domestic cash seizures by federal agencies proceed under the Civil Asset Forfeiture Reform Act (CAFRA) and the specific forfeiture statutes cited in the seizure notice. The most common statutes cited in domestic cash seizures include:
- 18 USC 981 — Civil forfeiture authority for property involved in or traceable to money laundering and other specified unlawful activity. This is the most commonly cited statute in domestic cash seizures by CBP and HSI.
- 18 USC 1956 and 1957 — The federal money laundering statutes. Property involved in a transaction that constitutes money laundering, or that represents the proceeds of specified unlawful activity, is subject to forfeiture under these provisions.
- 21 USC 881 — Drug proceeds forfeiture. Money that constitutes proceeds of a controlled substance offense, or that was used or intended to be used in exchange for controlled substances, is subject to forfeiture under this statute. This is the primary authority in DEA-initiated seizures.
Under CAFRA, the government bears the burden of proving by a preponderance of the evidence that the seized property is subject to forfeiture. You are not required to prove your innocence — the government must prove its case. However, once the government meets its initial burden, the burden can shift to you to establish that you are an innocent owner. This is why documentation of the legitimate source and intended use of the funds is as critical in domestic seizures as it is in international ones.
Your Response Options After a Domestic Seizure
The options for contesting a domestic cash seizure mirror those available in international seizure cases, though the specific procedures depend on which agency seized the money:
- Administrative petition for remission or mitigation — Filed with the seizing agency’s forfeiture office. Presents the factual and legal case for return of the funds, including documentation of legitimate source and intended use. This is the fastest and least expensive path and should be the first step in most cases.
- CAFRA judicial claim — Forces the government to file a civil forfeiture complaint in federal court within 90 days. Puts the burden of proof on the government and gives you full discovery rights. The right choice when the administrative process has been exhausted or when the facts strongly favor judicial review.
- Offer in compromise — A negotiated settlement proposing return of a portion of the seized funds in exchange for resolution of the forfeiture claim. Useful when full recovery is unlikely or when a negotiated outcome is preferable to the time and cost of litigation.
The same two evidentiary requirements that apply in international seizure cases apply here: you must be able to document the legitimate source of the funds and their legitimate intended use. See our full guide on what evidence you need to recover seized cash.
What You Should Do Immediately After a Domestic Seizure
The steps to take after a domestic cash seizure are the same as after an international one — with one additional consideration:
- Identify the seizing agency. The notice of seizure will identify which agency took the money and which forfeiture office is administering the case. This determines where to file and which procedures apply. Do not assume it was CBP — in most domestic airport and carrier seizures, it is DEA, HSI, or a local agency acting under federal adoption.
- Note the response deadline. The notice will state the deadline for filing a petition or CAFRA claim. It is typically 30 to 35 days from the date of the notice, not the date you received it. Act immediately.
- Start gathering documentation. Bank statements, tax returns, business records, contracts, and any other documents that establish where the money came from and what it was for. The sooner you begin, the stronger your case will be.
- Do not speak to law enforcement without an attorney. Anything you say about the money — its source, its destination, its purpose — can be used against you in forfeiture proceedings and in any related criminal investigation. Politely decline to discuss the matter and contact an attorney immediately.
