You have an ISF penalty notice for $5,000

The claim in your hand is liquidated damages under your customs bond, not a fine handed down by a judge, and that difference is the good news: a claim under a bond can be petitioned and it can be mitigated. Here is what the $5,000 is, how long you have to answer it, what CBP's published guidelines allow on a first violation, and the one popular belief about ISF penalties that is simply false.

Petition for relief

60 days from the date the notice was mailed to you

19 CFR 172.3(b) runs the 60 days from the date of mailing of the notice of claim, not the date you opened it. Two things move that window, so do not treat it as a flat rule: 172.3(c) lets Fines, Penalties and Forfeitures grant an extension, and 172.3(e) says that where fewer than 180 days remain on the statute of limitations, FP&F may set a shorter reasonable period, but not less than 7 working days. Read the notice for the period it actually gives you, and if you want us to read it with you, send it over today.

What the $5,000 actually is

It is a claim for liquidated damages under the bond you already have on file. The amount is not discretionary and it is not calculated from the value of your cargo. It comes from a condition written into every basic importation and entry bond at 19 CFR 113.62(j): if the principal defaults with regard to any obligation, the principal and surety, jointly and severally, agree to pay liquidated damages of $5,000 for each violation.

So CBP is not accusing you of smuggling. It is calling a term of your own bond. That is why the answer to it is a petition rather than a defense, and why the numbers below are cancellation amounts rather than plea bargains.

One structural note that matters if you import without a continuous bond. If no bond is in place, liquidated damages cannot be assessed for failing to file an ISF at all, because there is no bond condition to breach. That is not a loophole worth chasing: the remedies that replace it are holds, seizure, and 19 USC 1595a(b), which are worse than a claim you can petition.

There is no $10,000 cap, and the myth costs people money

You will read everywhere that ISF damages are $5,000 per violation, capped at $10,000 per filing. The cap is not real. The $10,000 figure people repeat is the amount of a stand-alone ISF single-transaction bond, which is a bond size, not a limit on damages.

More than one violation can attach to a single ISF, and CBP's own ISF FAQ walks through exactly that: $5,000 for a late filing, $5,000 for an inaccurate filing, and $5,000 for the first inaccurate update. One shipment, three violations, $15,000 of exposure. If you are budgeting your problem against a $10,000 ceiling, you may be budgeting for the wrong number.

Violations that can attach to a single ISF
ViolationLiquidated damagesWhere it comes from
Late ISF$5,000Bond condition, 19 CFR 113.62(j)
Inaccurate ISF$5,000Bond condition, 19 CFR 113.62(j)
First inaccurate ISF update$5,000Bond condition, 19 CFR 113.62(j)
No bond on file at allNone assessableNo bond condition to default; holds, seizure and 19 USC 1595a(b) instead

The three violation types above are the ones CBP's ISF FAQ describes stacking on one filing. The $10,000 figure circulating as a cap is the stand-alone ISF single-transaction bond amount.

What CBP's mitigation guidelines provide

This is the part worth reading twice, because it is where a $5,000 claim usually stops being a $5,000 problem. CBP Dec. 09-26, published in the Customs Bulletin, Vol. 43 No. 28, July 17, 2009, sets the mitigation guidelines for ISF liquidated damages. Section IV.D provides that on a first violation the claim may be cancelled upon payment of an amount between $1,000 and $2,000, depending on the presence of mitigating or aggravating factors, if CBP determines that law enforcement goals were not compromised by the violation. For subsequent violations, the guidelines provide for an amount not less than $2,500.

Three conditions travel with that range and none of them is optional. First, it applies to late, inaccurate and inaccurate-update violations, and not to a failure to file at all. Second, it is conditioned on law enforcement goals not being compromised, and the guidelines say plainly that no relief will be granted if CBP determines that law enforcement goals were compromised. Third, it is a cancellation amount available on petition, not the amount of the claim: the claim still issues at $5,000, and the lower figure is what CBP may accept to cancel it.

These are published guidelines issued under 19 USC 1623, not regulation, which is why we write that CBP's guidelines provide for these amounts rather than promising you a price. CBP Dec. 09-26 is dated July 17, 2009, and guidelines can be superseded by a later Customs Bulletin notice, so we confirm the current guideline before a petition goes in rather than quoting a 2009 range at you as settled. A good petition is the difference between the two ends of that range, and sometimes between relief and none.

Cancellation amounts under CBP's published guidelines
SituationGuideline amountCondition
First violation$1,000 to $2,000Depending on mitigating or aggravating factors
Subsequent violationsNot less than $2,500Same law enforcement condition applies
Law enforcement goals compromisedNo reliefStated flatly in the guidelines
Failure to file at allOutside these guidelinesThe range covers late, inaccurate and inaccurate-update violations

CBP Dec. 09-26, Customs Bulletin Vol. 43 No. 28, July 17, 2009, section IV.D. These are published guidelines under 19 USC 1623, not regulation, and a later Customs Bulletin notice can supersede them, so we confirm the current guideline before petitioning. The assessed claim remains $5,000; these are amounts CBP may accept to cancel it on petition.

The deadline you probably missed, and the one still ahead of you

Almost every ISF violation we see traces to the same misunderstanding, and the regulation is more precise than the shorthand everyone repeats. Under 19 CFR 149.2(b), eight of the importer's elements are due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port: seller, buyer, importer of record number or FTZ applicant identification number, consignee number, manufacturer or supplier, ship to party, country of origin, and the HTSUS number.

The other two ride a different clock. Container stuffing location and consolidator, the stuffer, are due as early as possible and in no event later than 24 hours prior to arrival in a United States port, or upon lading at a foreign port that is less than a 24 hour voyage from the closest United States port. So it is wrong to say all ten elements are due 24 hours before lading, and it is much more expensive to say the ISF is simply due before arrival. Eight elements ride the lading clock, which means the filing has to be underway while your supplier is still stuffing the container. Importers who plan the whole thing around the arrival date are late before the vessel ever sails.

The deadline still ahead of you is the petition window in the box at the top of this page. Answer that one and the first one becomes a process fix rather than a recurring bill.

For completeness on the outside edge: the statute of limitations on a claim like this is six years, under 28 USC 2415. That is CBP's window to act, not yours to relax in. Your window is the one printed on your notice.

The honest limit

If your petition window has already closed, a broker cannot reopen it. That is the part of this we cannot fix, and you should be suspicious of anyone who tells you otherwise. What is still worth doing in that case is separating what is settled from what is not: whether more claims are coming on other filings, whether your ISF process is still producing violations, and whether the bond you are carrying is the right one for how you import.

If the window is open, the useful work is immediate and specific. It turns on the date your notice was mailed, the case number, whether this is a first violation for your importer number, and what actually went wrong on the filing. Those four facts decide everything, and none of them are on this page. They are on your paperwork.

FAQ

Is the ISF penalty really capped at $10,000?

No. There is no per-filing cap. Liquidated damages are $5,000 per violation under the bond condition at 19 CFR 113.62(j), and more than one violation can attach to a single ISF. CBP's own ISF FAQ describes $5,000 for a late filing, $5,000 for an inaccurate filing and $5,000 for the first inaccurate update, which is $15,000 on one shipment. The $10,000 figure that circulates as a cap is the amount of a stand-alone ISF single-transaction bond.

How long do I have to respond to an ISF liquidated damages notice?

19 CFR 172.3(b) gives 60 days from the date the notice of claim was mailed to the bond principal. Read your notice rather than the calendar, because 172.3(c) lets FP&F grant an extension and 172.3(e) lets FP&F set a shorter reasonable period, never less than 7 working days, where fewer than 180 days remain on the statute of limitations.

Can a $5,000 ISF penalty be reduced?

Often, on petition. CBP's published guidelines in CBP Dec. 09-26 section IV.D provide that a first violation may be cancelled upon payment of $1,000 to $2,000 depending on mitigating and aggravating factors, and subsequent violations at not less than $2,500, in both cases only if CBP determines that law enforcement goals were not compromised. It does not cover a failure to file at all, and the claim itself still issues at $5,000. These are published guidelines rather than regulation, so we confirm the guideline currently in force before a petition goes in.

When is the ISF actually due?

Two clocks, not one. Under 19 CFR 149.2(b), eight elements are due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port: seller, buyer, importer of record or FTZ applicant identification number, consignee number, manufacturer or supplier, ship to party, country of origin and the HTSUS number. Container stuffing location and consolidator are due as early as possible and no later than 24 hours prior to arrival in a United States port, or upon lading at a foreign port less than a 24 hour voyage away. Reading the whole filing as an arrival deadline is behind most of the late-filing claims we see.

What happens if I just ignore the notice?

The claim stands and becomes collectible against you and your surety jointly and severally, your surety will look to you for it, and the petition route that could have cancelled it for a fraction closes. CBP has six years to act on the claim under 28 USC 2415. You do not have six years to answer it.

I do not have a customs bond. Can they still hit me with $5,000?

Liquidated damages for failing to file an ISF depend on a bond condition to default under, so with no bond in place there is nothing to assess. That is not a good position to be in. Without a bond the tools that remain are holds, seizure and 19 USC 1595a(b), and none of those can be petitioned down the way a bond claim can.
