What 19 U.S.C. § 1433 and § 1436 Require

These two statutes work together to establish reporting requirements for vehicles and vessels arriving in the United States and to authorize CBP to impose civil penalties when those requirements are not met.

19 U.S.C. § 1433 — Reporting Requirements

Section 1433 requires that the master, operator, or person in charge of any vessel, vehicle, or aircraft arriving in the United States report its arrival to CBP, present all persons and merchandise on board for inspection to a CBP officer, and comply with related documentation requirements. The reporting requirement applies to commercial trucks, private vehicles, rail cars, and vessels. The documentation required includes invoices, bills of lading, ACE manifests, and other records depending on the type of conveyance and cargo involved.

The statute also requires that all cargo be manifested — meaning every item on the vehicle must be listed on the manifest before arrival. Cargo discovered during a CBP inspection that is not on the manifest is considered unmanifested cargo and constitutes a violation regardless of the reason it was omitted. For commercial shipments arriving from Canada and Mexico, 19 CFR § 123.92 adds a specific advance cargo information requirement — that information must be transmitted to CBP electronically before the carrier reaches the first U.S. port of entry.

19 U.S.C. § 1436 — Civil Penalty Authority

Section 1436 is the enforcement provision — it is what authorizes CBP to assess a monetary penalty when a carrier or operator violates the reporting and documentation requirements of § 1433. The statute identifies four categories of unlawful acts: failing to comply with § 1431, § 1433, or § 1434; presenting or transmitting any forged, altered, or false document, paper, information, data, or manifest to CBP without revealing the facts; failing to make entry or obtain clearance as required; and failing to comply with any regulation prescribed under those sections.

The civil penalty amounts are fixed by statute: $5,000 for a first violation and $10,000 for each subsequent violation. Any conveyance used in connection with a violation is also subject to seizure and forfeiture. In addition, when merchandise is imported or brought into the United States in a conveyance that was not properly reported or entered, the carrier faces a separate civil penalty equal to the value of the merchandise — on top of the standard $5,000 or $10,000 penalty — and that merchandise may be seized and forfeited unless properly entered by the importer or consignee.

For intentional violations, § 1436 also carries criminal exposure: a fine of up to $2,000 or imprisonment for up to one year, or both. If the conveyance carries prohibited merchandise, the criminal penalty increases to up to $10,000 or five years imprisonment, or both.

Common Violations That Trigger § 1433 and § 1436 Penalties

Based on CBP penalty notices issued at northern border ports, the most frequently cited violation categories are as follows. Each category has different mitigation potential depending on the facts and the carrier’s prior history.

Failure to Report Arrival

A carrier that crosses into the United States at an unmanned port, uses an unauthorized crossing, or fails to present at the designated CBP inspection area has failed to report arrival — one of the most basic requirements of § 1433. This violation is sometimes committed by drivers who are unfamiliar with the port of entry layout, who follow GPS directions that bypass the inspection facility, or who cross at a location that was formerly staffed but has since been reduced to unmanned status. It is also a common violation for private aircraft pilots who land at non-designated airports without reporting to CBP.

Unmanifested Cargo

Cargo discovered during a CBP physical examination that does not appear on the manifest is unmanifested cargo. Common examples include tools left in the cab, personal items belonging to the driver, merchandise loaded at the last minute without updating the manifest, or items overlooked during the manifest preparation process. Even a single item not listed on the manifest can support a § 1436 penalty — and if the unmanifested cargo has significant value, the additional value-based penalty under § 1436 can substantially exceed the base $5,000 or $10,000 amount.

False or Inaccurate Cargo Descriptions

When the physical cargo does not match the description on the manifest — for example, when the manifest lists “skids” but the actual cargo is cartons of merchandise, or when the number of pieces differs from what was declared — CBP may assess a penalty for presenting a false manifest under § 1436(a)(2). These violations frequently result from miscommunication between the shipper, broker, and carrier during the manifest preparation process.

ACE Manifest Errors

Incorrect consignee or shipper information transmitted electronically through the Automated Commercial Environment system prior to arrival can constitute a violation even if the physical documents presented at the port are correct. Under 19 CFR § 123.92, advance cargo information for commercial truck shipments from Canada must be transmitted at least 30 minutes before the carrier reaches the first U.S. port of entry; for rail, the requirement is 2 hours. Late, incomplete, or inaccurate ACE filings are a growing source of § 1436 penalties as CBP’s advance electronic filing requirements have expanded.

Failure to Present Required Documentation

A carrier that arrives at a port of entry without the required invoices, bills of lading, or other entry documentation — whether because the documents were not provided by the shipper, were left at the carrier’s terminal, or were lost in transit — has violated § 1433’s documentation requirements. CBP does not accept the absence of paperwork as a defense to the penalty, but the circumstances surrounding why documentation was missing can be a significant mitigating factor in the petition.

Improper Transport of Hazardous Materials

Carriers transporting hazardous materials through ports of entry are subject to additional documentation and routing requirements. A carrier that presents at a port without the required hazmat documentation, uses an unauthorized route, or fails to identify hazardous materials on the manifest faces both § 1436 penalties and potential referral to DOT for additional enforcement. These cases often involve the additional value-based penalty if the hazardous materials were not manifested.

Northern Border Ports Where These Penalties Are Commonly Issued

CBP issues § 1433 and § 1436 penalties at every northern border port of entry. The highest-volume ports for commercial carrier crossings — and therefore the highest volume of carrier penalty notices — include the following locations. Each port has its own FP&F office or refers matters to the relevant CBP field office, and enforcement priorities can vary by location.

CBP Mitigation Guidelines for § 1433 and § 1436 Penalties

CBP’s published mitigation guidelines for § 1433 and § 1436 violations establish ranges within which penalties can be reduced based on the nature of the violation, the carrier’s prior history, and the presence of mitigating or aggravating factors. These guidelines are the starting point for every petition — but they are not the ceiling. A well-prepared petition that documents the facts comprehensively, addresses the specific circumstances of the violation, and presents the carrier’s compliance posture can achieve results at or below the low end of the published range. The mitigation ranges below are drawn from CBP’s published guidelines and from GLCL’s own experience handling these cases.

How the Petition Process Works

When CBP issues a penalty notice under § 1433 or § 1436, the notice will identify the specific violation, the amount of the penalty, the port where the violation occurred, and the FP&F office handling the matter. The notice will also state the deadline for filing a petition for mitigation — typically 60 days from the date on the notice.

Step 1 — Review the Notice Carefully

Before doing anything else, read the penalty notice in full. Confirm the violation type CBP has alleged, the amount assessed, and the deadline. Check whether this is being treated as a first or subsequent offense — if CBP has incorrectly characterized your violation history, that is worth challenging directly in the petition. Note the FP&F office address where the petition must be submitted and confirm the response deadline from the date printed on the notice, not the date you received it.

Step 2 — Gather Documentation

The strength of your petition depends on the quality of your documentary record. You will need the original manifest, the ACE filing records, the bill of lading, the invoice, any communications between the carrier, dispatcher, shipper, and customs broker relating to the shipment, and any internal records that explain how the discrepancy occurred. If the violation involved a driver action at the port — such as using the wrong crossing or failing to stop — a written statement from the driver explaining what happened is also important.

Step 3 — Prepare and File the Petition

The petition must be addressed to the FP&F Director at the port that issued the penalty, submitted within the deadline, and structured to present the factual record, the legal basis for mitigation, and the mitigating factors that support a reduction. The petition should also address any aggravating factors CBP is likely to raise — such as prior violations — proactively, and explain what the carrier has done to prevent recurrence. A supplemental petition can be filed if the initial petition receives an unfavorable response.

Step 4 — FP&F Decision

The FP&F officer assigned to the matter reviews the petition and issues a written decision. If the initial petition is denied or the reduction is insufficient, a supplemental petition presenting additional facts or legal arguments can be filed. If all administrative options are exhausted, the matter can be escalated to CBP’s Office of Regulations and Rulings or litigated in federal court, though most carrier penalty matters are resolved at the administrative petition stage.

What Evidence Helps Your Petition

CBP’s mitigation guidelines give FP&F officers discretion within a range. The evidence and arguments in your petition determine where within that range — or below it — the outcome lands. The following categories of evidence consistently make a difference in carrier penalty petitions.

Clean Prior Violation History

A carrier with no prior § 1433 or § 1436 violations, or with a long gap since any prior violation, is in a significantly better position than a carrier with a recent history of the same type of violation. If your company crosses at the northern border regularly and has a strong compliance record, that record should be documented and presented in the petition — not assumed. CBP checks its own systems for prior violations at any port, not just the port where the current penalty was assessed.

Root Cause Analysis

CBP responds well to petitions that explain specifically how the violation occurred — not just that it was a mistake. If a dispatch error caused the wrong cargo description to appear on the ACE manifest, explain the dispatch process, identify where the error entered the system, and describe what controls have been implemented to prevent recurrence. A vague statement that “a clerical error occurred” is less effective than a specific, documented account of what happened and why.

Corrective Action

Describing the steps your company has taken since the violation to improve compliance is a standard element of an effective petition. This can include driver training on reporting requirements, updated dispatcher checklists, additional review steps for manifest preparation, or new broker coordination procedures. The more specific and documented these steps are, the more weight they carry with the FP&F officer reviewing the petition.

Good Faith Cooperation With CBP

If the driver cooperated fully with CBP officers at the port — provided requested documents, answered questions honestly, and did not attempt to conceal the discrepancy — that cooperation should be documented in the petition. CBP officers’ notes from the port examination are part of the penalty record, and cooperation at the port is a recognized mitigating factor under CBP’s guidelines.

Related CBP Penalty Types

Carriers crossing the northern border may encounter other types of CBP penalties in addition to § 1433 and § 1436 violations. The following penalty types frequently appear alongside or in connection with carrier manifest violations.
