Penalties for customs duty and tariff evasion run on three tracks that the government can pursue at the same time: civil fines that reach up to the full domestic value of the imported goods, criminal sentences of up to 20 years for smuggling, and permanent forfeiture of the merchandise itself. On top of any penalty, the importer still owes every dollar of duty that should have been paid, plus interest. A single fraudulent shipment can generate consequences many times larger than the duty the importer was trying to avoid.
Civil Penalties Under 19 U.S.C. § 1592
The main civil enforcement tool is 19 U.S.C. § 1592. It prohibits entering merchandise by means of any false statement, document, or material omission, whether or not the government actually loses revenue.1Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence The statute sorts violations into three fault tiers, each with its own ceiling.
At the negligence tier, when an importer fails to exercise reasonable care, the maximum penalty is the lesser of the domestic value of the merchandise or two times the lost duties and fees. If no duties were affected, the cap is 20 percent of the dutiable value.1Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence
Gross negligence, meaning reckless disregard for accuracy, raises the ceiling to the lesser of the domestic value or four times the lost duties and fees. Where no duty loss occurred, the cap is 40 percent of the dutiable value.1Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence
Fraud, meaning an intentional false statement or omission of material facts, carries the harshest civil penalty: up to the full domestic value of the merchandise. There is no alternative cap tied to lost revenue.1Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence
Those are statutory ceilings. CBP’s own mitigation guidelines set narrower disposition ranges within each tier. Negligence penalties typically fall between 0.5 and 2 times the total duty loss. Gross negligence runs from 2.5 to 4 times. Fraud cases generally start at 5 to 8 times the duty loss, capped at domestic value.2eCFR. 19 CFR Part 171 Appendix B – Customs Fines, Penalties, and Forfeitures Whatever number lands, it stacks on top of the underlying unpaid duties, which the importer must still pay in full.
Interest on Unpaid Duties
Interest attaches to every dollar of duty that should have been paid. The rate follows the IRS underpayment formula under 26 U.S.C. § 6621, which is the federal short-term rate plus three percentage points. For the first quarter of 2026, that works out to 7 percent.3Federal Register. Quarterly IRS Interest Rates Used in Calculating Interest on Overdue Accounts and Refunds of Customs Duties Interest runs from the date of liquidation until the importer actually pays. The longer the evasion sits undetected, the larger the bill grows.
Criminal Prosecution
When the conduct is deliberate and systematic, federal prosecutors can move the case out of the civil column and into criminal court. Several statutes are available, and the exposure escalates with the seriousness of the conduct.
False Classification and False Statements
Under 18 U.S.C. § 541, anyone who knowingly enters goods at less than their true weight or measure, or under a false classification, to pay less than the legal duty faces up to two years in federal prison.4Office of the Law Revision Counsel. 18 USC 541 – Entry of Goods Falsely Classified A companion statute, 18 U.S.C. § 542, covers entry through fraudulent invoices, false declarations, or any other deceptive act or document, also carrying a maximum of two years per offense.5Office of the Law Revision Counsel. 18 USC 542 – Entry of Goods by Means of False Statements Because both statutes rely on the general federal fine provision, the monetary exposure is up to $250,000 per count for an individual and $500,000 per count for a corporation.6Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
Prosecutors must prove intent beyond a reasonable doubt, a much higher bar than the civil standard. Customs investigators build these cases over months or years, often with cooperating witnesses. Double invoices and altered certificates of origin tend to speak for themselves.
Smuggling
The most serious criminal exposure sits under 18 U.S.C. § 545. Anyone who knowingly and willfully smuggles merchandise that should have been invoiced, or who imports goods contrary to law, faces up to 20 years in prison.7Office of the Law Revision Counsel. 18 USC 545 – Smuggling Goods Into the United States The same statute reaches anyone who receives, conceals, or facilitates the sale of goods they know were imported illegally. Mere possession of smuggled merchandise can support a conviction unless the defendant can explain it to the jury’s satisfaction. Goods imported in violation of § 545 are automatically subject to forfeiture.
Seizure and Forfeiture of the Goods
Beyond fines and prison time, the government can take the merchandise itself. CBP has authority to seize shipments at the port of entry or from a bonded warehouse when a violation is found. Once seized, the goods are held while the government decides whether to pursue forfeiture, which permanently transfers ownership to the federal government.
Two tracks exist depending on value. If the seized merchandise is worth $500,000 or less, CBP can process the forfeiture administratively without going to court.8Office of the Law Revision Counsel. 19 USC 1607 – Seizure; Value $500,000 or Less Higher-value or contested cases go through judicial forfeiture in federal district court, where the importer has the right to a full hearing. After forfeiture is final, the government may destroy the goods, use them for official purposes, or sell them at auction.
An owner whose merchandise has been seized can file a petition for relief asking CBP to return the goods or reduce the forfeiture amount. The deadline is short: 30 days from the date the notice of seizure was mailed.9eCFR. 19 CFR Part 171 Subpart A – Application for Relief If fewer than 180 days remain on the statute of limitations, CBP can compress that window to as little as seven business days. Extensions exist but are not guaranteed.
Cutting the Penalty Through Prior Disclosure
An importer who finds a problem and reports it before CBP opens a formal investigation can drop the civil penalty sharply. The statute lays out the reduced ceilings.10Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence For negligence or gross negligence, the penalty falls to the interest on the unpaid duties, provided the importer tenders the duty owed. For fraud, the penalty is reduced to 100 percent of the lost duties (rather than the full domestic value), or 10 percent of the dutiable value if no duties were affected.
The catch is timing. The disclosure has to come before the importer knows CBP has begun investigating. A person is presumed to have known about an investigation once a customs agent has made inquiries, requested records, issued a pre-penalty notice, or seized the goods.11eCFR. 19 CFR 162.74 – Prior Disclosure The disclosure itself must identify the merchandise, the entry numbers or ports involved, the specific false statements or omissions, and the correct information. Oral disclosures need a written follow-up within 10 days. The importer must pay the outstanding duties at the time of disclosure or within 30 days after CBP calculates the amount.
Prior disclosure also blocks seizure of the merchandise. That matters, because recovering seized goods requires a separate and slower legal fight.
How Long CBP Can Come After You
The government does not have unlimited time. For civil penalties under § 1592, the general limitation is five years from the date of the violation. Fraud runs on a different clock: five years from the date the fraud was discovered, which can push the window out significantly when the scheme was well hidden. Forfeiture actions must be filed within two years after the government discovers the property’s involvement in the violation, or five years from the violation itself, whichever is later. The clock pauses while the person is outside the country or while the property is concealed.
Criminal charges carry their own limitations under federal law, generally five years for most felony offenses. Because customs fraud often surfaces during routine audits or through informant tips years after entry, the discovery rule for civil fraud can keep an importer exposed well beyond what the calendar suggests.
Recordkeeping Penalties Are Separate
Every importer, consignee, entry filer, and customs broker must keep records related to each importation for five years from the date of entry.12Office of the Law Revision Counsel. 19 USC 1508 – Recordkeeping That covers invoices, shipping documents, classification decisions, and any electronic data tied to the entry. Drawback records must be retained until three years after the claim is liquidated. CBP can demand access at any time during the retention period.
Failing to produce records on lawful demand carries its own penalties, on top of any evasion charge. A willful failure can cost up to $100,000 per release of merchandise, or 75 percent of the appraised value, whichever is less. A negligent failure can cost up to $10,000 per release, or 40 percent of the appraised value.13Office of the Law Revision Counsel. 19 USC 1509 – Examination of Books and Witnesses If the missing records related to a preferential duty rate, CBP can also reliquidate the entry at a higher rate. A destroyed file or a lost laptop can turn a closed entry back into a live liability.
