Customs Manifest Requirements Under 19 USC 1431: Filing and Penalties

Customs manifest requirements come from 19 USC 1431 and require the master or person in charge of any vessel, aircraft, or vehicle arriving in the United States to file a document identifying the transport and describing every piece of cargo on board before anything is unloaded.¹ The specifics — what data goes on the form, when it has to reach Customs and Border Protection, and what a violation costs — vary by transport mode, and almost all of it now moves electronically through the Automated Commercial Environment.

Who Has to File

The filing duty sits with whoever commands the arriving transport. On a ship, that is the master. On an aircraft, the pilot or the airline’s designated agent. On a truck or rail car, the driver or the carrier’s authorized representative.¹ An authorized agent of the vessel’s owner or operator can sign and transmit the manifest on the master’s behalf, which is how most large shipping lines actually handle it.

The duty extends to any vessel arriving from a foreign port, any foreign vessel arriving from a domestic port, any U.S. vessel carrying foreign merchandise that has not yet been entered, and any vessel that has visited a hovering vessel outside U.S. territorial waters.² Small size or owner-operation does not exempt a commercial vehicle.

What Goes on the Manifest

The Secretary of the Treasury sets the specific data elements by regulation under 19 USC 1431(d).¹ A complete cargo manifest covers five core areas:

Vessel or vehicle identity: name, nationality, and voyage or trip number.
Ports: the foreign port where cargo was loaded and the U.S. port of arrival.
Cargo description: a specific description of the goods, the marks and numbers on containers or packages, and the total number of packages or quantity.
Shipper and consignee: full names and physical addresses on both ends.
Bill of lading number linking the manifest line to the shipping contract.

Vague cargo descriptions are one of the most common reasons CBP flags a shipment. Inspectors match the goods on the dock against the paperwork, so the marks, numbers, and descriptions have to correspond to what is actually in the container. Shipper and consignee identities matter for the same reason: CBP uses them to trace chain of custody when something does not add up.

Hazardous Materials

Hazmat shipments need additional fields on top of the standard ones. The carrier must include the UN or North American hazardous materials code and a description of the material, and may add the hazard class code, an emergency contact name and phone number, and the flashpoint temperature.³ The hazmat code and description are mandatory whenever hazardous cargo is on board. Missing that flag creates a CBP compliance problem and a separate safety violation at the same time.

Empty Containers With Residue

A container that looks empty but holds residual cargo cannot be manifested as “empty.” Residue has to be classified, entered, and manifested, because CBP has a security interest in knowing what is inside every container crossing the border.⁴ For ocean shipments, different procedures apply depending on whether the residue exceeds 3% of the container’s capacity.

Filing Deadlines by Mode

The advance filing window depends on how the cargo is arriving. Each mode has its own cutoff, and missing it can hold up the entire shipment.

Ocean, containerized cargo: the electronic equivalent of CBP Form 1302 must reach CBP 24 hours before the cargo is loaded aboard the vessel at the foreign port. This is the “24-hour rule.”⁵
Ocean, bulk and exempt break-bulk cargo: data must be transmitted 24 hours before arrival at the U.S. port, not before loading at the foreign port.⁶
Air carriers: manifest data must be transmitted no later than 30 minutes before the aircraft is secured (doors closed) at the foreign departure point.⁷
Commercial trucks: one hour before arrival at the U.S. border. Free and Secure Trade (FAST) loads get a shorter 30-minute window.⁸
Rail: no later than two hours before the train arrives at the first U.S. port of entry.⁹

These are hard cutoffs. If CBP has not received the data by the specified time, the cargo can be held or denied permission to proceed. For ocean carriers, missing the 24-hour pre-loading deadline can mean the container is not loaded onto the vessel at the foreign port at all.

How the Filing Actually Happens

Paper manifests still exist for narrow situations, but the great majority of cargo declarations now move through the Automated Commercial Environment (ACE) or the older Automated Manifest System (AMS). Ocean carriers submit the electronic equivalent of CBP Form 1302, the Inward Cargo Declaration.¹⁰ Air, truck, and rail carriers each have their own ACE modules. Whatever the transmission method, the legal responsibility for accuracy stays with the master or person in charge.

The 10+2 Rule for Ocean Shipments

For ocean cargo, the carrier manifest is only half of the advance data picture. Importers separately file an Importer Security Filing (ISF) with ten data elements, and the vessel-operating carrier provides two additional data sets. CBP calls this the “10+2” rule.¹¹

The importer’s ten elements are: importer of record number, consignee number, seller name and address, buyer name and address, ship-to party, manufacturer name and address, country of origin, commodity HTS-6 code, container stuffing location, and consolidator name and address. The carrier’s two elements are the vessel stow plan and container status messages.

The ISF has to be filed no later than 24 hours before the cargo is loaded, the same clock as the containerized carrier manifest. Each ISF links to the manifest at the shipment level through the lowest bill of lading number in AMS.¹¹ Mismatched bill of lading numbers between the ISF and the carrier manifest are a frequent source of flags, so importers and carriers need to coordinate that number early.

Manifest Data Is Partly Public

Manifest information is not fully private. Under 19 USC 1431(c), the name and address of each importer or consignee, the name and address of the shipper, and the general character of the cargo are all subject to public disclosure when they appear on a vessel or aircraft manifest.¹² Competitors, journalists, and data aggregators pull this data routinely.

Importers and consignees who want their identities kept out of public view can file a biennial certification requesting confidential treatment. Once approved, CBP removes the shipper name and address, consignee name and address, and notify party information from public manifest data.¹³ The certification runs two years; renewal requests should reach the Vessel Manifest Program Manager at least 60 days before the current one expires.

Separately, the Secretary of the Treasury can withhold information on a shipment-by-shipment basis when disclosure would pose a threat of personal injury or property damage. CBP is also required to strip personally identifiable information like Social Security numbers and passport numbers from any manifest before public release.¹²

Penalties for Getting It Wrong

Two statutes drive manifest penalties, and they cover different failures.

Under 19 USC 1584, a master or person in charge who fails to produce a manifest when an officer demands it faces a $1,000 penalty. Merchandise found on board that was not listed on the manifest, or that does not match what was declared, brings a penalty equal to the lesser of $10,000 or the domestic value of the undeclared goods. Merchandise listed on the manifest but not actually on the vessel triggers a separate $1,000 penalty.¹⁴

Under 19 USC 1436, presenting a forged, altered, or false manifest carries a civil penalty of $5,000 for a first violation and $10,000 for each subsequent violation. The conveyance itself can be seized and forfeited. Intentional violations add criminal exposure: a fine up to $2,000 or one year in prison, or both. If the vessel is carrying prohibited merchandise, the criminal fine rises to $10,000 and the prison term to five years.¹⁵

On top of the statutory fines, 19 USC 1431(d) makes the owner, operator, or any party responsible for a manifest irregularity liable for whatever penalty the law prescribes.¹ CBP can also deny permission to unload cargo from a vessel that arrives without a valid manifest, and repeat noncompliance can cost a carrier trading privileges at specific ports.

Petitioning to Reduce a Penalty

An initial penalty is not the final number. A petition for mitigation goes to the Fines, Penalties, and Forfeitures Officer at the port where the violation happened. If that petition is denied or the relief is not enough, the carrier can file a supplemental petition within 60 days of the decision, whether or not the mitigated amount from the first round has been paid.¹⁶ From there, denied petitions get forwarded to a designated CBP Headquarters official. When fewer than twelve months remain before the statute of limitations would bar the government’s claim, the deciding official may require the carrier to sign a waiver extending that deadline as a condition of accepting the petition. Mitigation tends to work best for carriers who can show reasonable care and a genuinely unintentional error.

Record Retention

Federal regulations require carriers to keep manifests and supporting documentation for five years from the date of entry or the date the record was created. Records for manifested cargo exempt from formal entry need to be kept only two years.¹⁷ CBP can audit at any point in that window, so the files need to stay accessible, not archived off to a place no one can reach.
