CBP Penalty Mitigation: Petitions Under 19 U.S.C. 1618

Under 19 U.S.C. 1618, an importer or other party against whom CBP has issued a penalty may petition the agency to remit or mitigate that penalty. A well-prepared petition, filed on time and supported by the right evidence, can substantially reduce the amount owed. The governing procedures are found in 19 CFR Part 171, and the outcome depends heavily on how CBP weighs published mitigating and aggravating factors.

Why the Petition Right Matters

CBP penalties under 19 U.S.C. 1592 can be severe. The statute establishes three culpability levels: negligence, gross negligence, and fraud. Penalty ceilings at the higher levels can equal or exceed the domestic value of the merchandise involved. For many importers, the assessed penalty bears little resemblance to actual harm caused, which is precisely why Congress created a formal mitigation pathway. A petition is not an appeal to a court; it is an administrative request asking CBP to exercise its discretionary authority to reduce or cancel the penalty before any payment is due.

The Petition Process Under 19 CFR Part 171

Where and how to file

Petitions must be filed with the CBP Center of Excellence and Expertise (CEE) or the office that issued the penalty notice, as directed in the notice itself. The petition must be in writing and signed by the petitioner or an authorized representative, such as a licensed customs broker or attorney.

The 60-day deadline

Under 19 CFR Part 171, the petitioner generally has 60 days from the date of mailing of the penalty notice to submit a petition. This deadline is firm. If you miss it, CBP may still accept a late petition at its discretion, but there is no guarantee, and the leverage you have in the administrative process diminishes significantly. Calendar the deadline the day you receive the notice.

What the petition must contain

• A clear statement identifying the penalty notice (case number, date, amount).
• The specific grounds on which remission or mitigation is requested.
• All supporting facts, documents, and arguments relevant to those grounds.
• A statement whether the petitioner believes the alleged violation occurred and, if so, an explanation of the circumstances.

Omitting key facts or documents at the petition stage can hurt you later. CBP evaluates petitions primarily on the written record, so this is the time to present everything favorable to your position.

Supplemental petitions

If CBP issues a supplemental penalty notice, or if the petitioner obtains new information after the original petition is filed, a supplemental petition may be submitted. The same format and factual-support requirements apply. Supplemental petitions are also used when CBP's initial decision on a petition is unfavorable and the petitioner has additional grounds or evidence to present. There is a defined window for supplemental filings stated in CBP's written decision, so review that decision carefully and act promptly.

Mitigating Factors CBP Considers

CBP's published penalty mitigation guidelines identify specific circumstances that can reduce a penalty. While the exact weight assigned to each factor is discretionary, the following consistently appear in CBP's framework:

• Cooperation with CBP: Voluntarily disclosing the violation, providing complete records promptly, and assisting in the investigation are among the most powerful mitigating factors.
• Prior disclosure: A valid prior disclosure filed before CBP has initiated a formal investigation can qualify the importer for significantly reduced penalties. See our related guide on CBP Prior Disclosure: How It Works and When to File for details on that separate but related process.
• Inexperience: A new importer with no prior history of violations may receive more favorable treatment than a seasoned importer who should have known better.
• Absence of prior violations: A clean compliance record is a meaningful mitigating factor.
• Immediate remedial action: Taking corrective steps, such as implementing a compliance program, retraining staff, or amending entry procedures, before the petition is filed demonstrates good faith.
• Inability to pay: If a penalty in full would cause genuine financial hardship, documented financial information can support a reduced settlement. Supporting financials must be detailed and credible.
• Minimal harm to government revenue: Where duties were paid in full or the revenue impact was negligible, CBP may view the violation more leniently.

Aggravating Factors That Can Increase Exposure

Just as certain facts help a petitioner, others work against them. CBP's guidelines identify aggravating factors that can prevent mitigation or push the penalty toward the statutory maximum:

• Prior violations: A history of similar violations, especially those that were previously mitigated, signals that earlier leniency failed to deter non-compliance.
• Intentional conduct: Evidence that the violation was deliberate or designed to evade duties shifts the culpability level toward fraud and limits mitigation.
• Obstruction: Failure to cooperate with CBP's investigation, providing false or incomplete records, or destroying documents are serious aggravating circumstances.
• Substantial revenue loss: Large underpayments of duty, particularly those spread across many entries, weigh against significant mitigation.
• Continuing violations: Violations that persisted over a long period after the importer had reason to know of the problem are viewed more harshly than isolated incidents.

Understanding these factors before you draft a petition helps you frame the narrative accurately and avoid inadvertently highlighting unfavorable facts.

How CBP Decides and What Comes Next

The decision letter

After reviewing the petition, CBP issues a written decision. The decision will either grant mitigation (reducing the penalty to a stated amount), deny mitigation, or offer a settlement figure. If mitigation is granted, the petitioner typically has a specified period to pay the mitigated amount. Failure to pay within that window can cause the offer to lapse and the original penalty to be reinstated.

Further review options

If the petition is denied or the mitigated amount is still unacceptable, the petitioner may file a supplemental petition with additional grounds, or pursue further administrative or judicial review. Each of those paths has its own deadlines and procedural requirements. The initial petition decision letter will outline what options remain and how long you have to exercise them.

Relationship to audits and Form 29 actions

Penalty notices often arise out of CBP audits or post-entry review. Understanding how those processes work can help importers respond strategically. Our guides on CBP Focused Assessment: How the Audit Works and How to Prepare and CBP Form 29 Notice of Action: Proposed vs. Taken and Your Options explain the earlier stages of these proceedings.

What Importers Should Do

1. Act immediately upon receiving a penalty notice. Calendar the 60-day petition deadline, identify the issuing CBP office, and begin gathering all relevant entry records, correspondence, and internal compliance documentation.
2. Assess culpability honestly before filing. Review each transaction at issue and determine whether the facts support a negligence, gross negligence, or fraud characterization. Framing arguments at the wrong culpability level undermines credibility with CBP reviewers.
3. Document every mitigating factor with evidence. Assertions without supporting documents carry little weight. Attach compliance program records, training logs, corrective-action plans, financial statements, or any other materials that substantiate your claims.
4. Consult a licensed customs broker or trade attorney before filing. The petition is a legal document that becomes part of the administrative record. Professional review before submission can prevent missteps that are difficult to correct later.
