In August 2013, CBP officers at Luis Muñoz Marín International Airport in San Juan seized $34,685 from a passenger arriving from Venezuela. The money was not all cash. Officers found an envelope holding $12,000, a second envelope tucked inside a book holding $3,335, and a plastic bag containing seven checks worth $19,350. The traveler, a Florida resident, had given officers an inaccurate figure. The currency was seized under bulk cash smuggling authority and Homeland Security Investigations made an arrest.
Most coverage of this case would stop at the total. The interesting question is narrower and more useful: of that $34,685, how much was actually reportable? Because the answer is not obviously all of it.
Not Every Check Counts Toward the $10,000
This is one of the least understood rules in the entire reporting regime, and it matters here because more than half the seized value was in check form.
The reporting obligation attaches to “monetary instruments,” a defined term. It reaches:
- Currency, U.S. and foreign, at its equivalent value.
- Traveler’s checks, in any form.
- Negotiable instruments, including personal checks, business checks, cashier’s checks, official bank checks, promissory notes, and money orders, where the instrument is in bearer form, endorsed without restriction, made out to a fictitious payee, or otherwise in a form where title passes on delivery.
- Incomplete instruments that are signed but have the payee’s name left blank.
- Securities or stock in bearer form.
It does not reach checks or money orders made payable to a named person that have not been endorsed, or that carry a restrictive endorsement. A check written to a specific payee and left unendorsed is not a monetary instrument for these purposes, because it cannot simply be handed to someone else and cashed.
The test is whether title passes on delivery
The rule is not about the type of paper. It is about whether whoever holds the instrument can convert it to money. A cashier’s check endorsed in blank travels like cash and is reportable. The same check made out to a named payee and left unendorsed does not, and is not. Signing the back of a check before you fly can change its status.
In this case the distinction did not save the traveler. The cash alone came to $15,335, which is over the threshold on its own, and an inaccurate declaration is a violation regardless of what else was in the bag. But the classification of the checks still mattered, for a reason covered further below.
Converting Cash to Checks Is Not a Workaround
Once people learn that some checks fall outside the definition, the obvious next thought is to restructure how they carry money. That instinct creates a worse problem than the one it solves.
Deliberately arranging your affairs to avoid triggering a reporting requirement is structuring, addressed at 31 U.S.C. § 5324, and it is an offense in its own right. Converting $30,000 in cash into instruments chosen specifically because they will not have to be reported is precisely the conduct the statute targets. The fact that each individual step is lawful is not a defense; the purpose behind the arrangement is the violation. Our page on structuring under 31 U.S.C. § 5324 covers how these allegations arise.
When in doubt, report it
Nothing prevents a traveler from listing non-reportable instruments on the form anyway. Over-reporting carries no penalty, no tax, and no limit. Under-reporting because of a technical argument about bearer form is a gamble made at the counter, in front of an officer, with no opportunity to consult anyone.
Puerto Rico Is U.S. Customs Territory
The seizure happened in San Juan on a flight from Venezuela, which is an international arrival into the United States and is treated exactly like an arrival at Miami or New York.
The point worth clarifying is the other direction. Travel between Puerto Rico and the U.S. mainland is domestic travel. There is no CBP currency reporting requirement on a flight from San Juan to Orlando, because no border is being crossed. Travelers sometimes assume the opposite because they see CBP and agricultural inspection personnel at the airport, and they occasionally assume the reverse as well, treating an international arrival into San Juan as somehow outside the reporting rules. Neither assumption is correct. Our page on cash seized at the San Juan port of entry covers how these cases are handled locally.
Why the Reportable Amount Still Matters After a Violation
A common assumption is that once a violation is established, the analysis is over and everything present is forfeitable. In practice the amount is contested territory, and it drives the outcome.
CBP’s mitigation guidelines work from the amount involved. Where relief is granted on payment of a fine, the fine is calculated as a proportion of that figure. A dispute over whether $19,350 in checks belonged in the calculation at all is therefore not academic, even in a case where the cash alone established the violation. The same is true of foreign currency conversion rates, of amounts belonging to a traveling companion, and of funds a third party can show they own.
Arguments like these are made in the written submission, with documentation, not at the inspection counter. Officers in the field are not adjudicating the definition of a monetary instrument, and a traveler who tries to litigate it on the spot generally makes matters worse. Our page on the best option for getting seized cash back from CBP covers how the choices differ and what each requires.
As for the envelope inside a book: that was enough for CBP to invoke bulk cash smuggling authority. Concealment for these purposes does not require a fabricated compartment, though the government still has to establish that the concealment was intended to evade the reporting requirement rather than to deter theft. Our page on bulk cash smuggling and CBP currency seizures covers that element. Outcomes in all of these matters depend heavily on the specific facts and the documentation available.

Frequently Asked Questions
Do checks count toward the $10,000 reporting threshold?
Some do and some do not. A check in bearer form, endorsed without restriction, or otherwise transferable by delivery counts. A check made payable to a named person and left unendorsed generally does not. Traveler’s checks always count.
Can I avoid the reporting requirement by carrying checks instead of cash?
Arranging your money specifically to stay below a reporting threshold is structuring, which is a separate offense. The fact that each step is individually lawful is not a defense where the purpose was to avoid the report.
Do I have to report cash flying between Puerto Rico and the mainland?
No. Puerto Rico is U.S. customs territory, so that travel is domestic and no CBP currency report is required. An international arrival into San Juan is a different matter and is treated like any other arrival into the United States.
If part of what CBP seized was not reportable, does that help me?
It can. Mitigation is calculated from the amount involved, so disputing whether particular instruments or funds belonged in that figure can affect what a fine looks like. The argument belongs in the written submission, supported by documentation.
