How Canadian Highway Carriers Get U.S. Authority to Haul Freight Into the United States

Overview

To cross commercially into the United States, a Canadian highway carrier typically needs the correct Canadian commercial registration, U.S. operating authority where applicable, a valid Standard Carrier Alpha Code, ACE eManifest capability, accurate shipment documents, and customs broker coordination when the freight requires formal release.

For most U.S.-bound commercial shipments, the Canadian carrier transmits trip, conveyance, driver, equipment, and shipment data to U.S. Customs and Border Protection before the truck reaches the border. The customs broker separately handles the entry or release process for shipments such as PAPS.

For Canadian carriers getting U.S. authority

Canadian trucking companies that want to haul commercial freight into the United States need more than Canadian operating registration. To report commercial freight to U.S. Customs and Border Protection, a Canadian carrier generally needs a SCAC code, ACE eManifest filing capability, PAPS barcode paperwork, broker coordination, and driver documents that match the U.S.-bound shipment.

A Canadian NSC number, CVOR certificate, provincial safety registration, or CBSA carrier code does not replace the SCAC code and ACE eManifest workflow used for U.S. customs reporting. Treat U.S. authority as its own onboarding workflow with separate account setup, customs reporting, and dispatch procedures.

What Canadian carriers should prepare

• Legal company name exactly as registered in Canada.
• Any trade names, operating names, or previous legal names.
• Province or territory of registration, incorporation date, and entity details.
• Physical and mailing addresses.
• Officer, owner, or director contact details.
• Canadian commercial carrier registration such as NSC, CVOR, or provincial safety registration where applicable.
• U.S. operating authority, USDOT, MC, insurance, and process agent requirements where applicable.
• SCAC code setup for U.S. customs reporting.
• ACE eManifest filing process through BorderConnect.
• Printed PAPS labels and ACE Manifest lead sheets for dispatch and driver workflows.

Commercial carrier registration

Before handling regular U.S.-bound freight, a Canadian trucking company should confirm that it is properly registered to operate commercially in its home jurisdiction and that its company details are consistent across dispatch, broker, ACE eManifest, and paperwork systems.

Carrier registration is separate from customs reporting, but it forms the operating foundation for cross-border freight. Dispatch should confirm which legal entity, Canadian registration, U.S. authority, SCAC, and carrier profile should be used before the company accepts U.S.-bound loads.

Registration tips

• Use the same legal business name across Canadian registration, U.S. authority, SCAC, broker, and eManifest records.
• Keep company address, contact, insurance, authority, driver, and equipment details current.
• Document which SCAC and company entity should be used by dispatch.
• Confirm requirements before onboarding new drivers, trucks, dispatch locations, or partner carriers.

U.S. operating authority

Some Canadian carriers need U.S. operating authority before hauling freight into or within the United States. Requirements can depend on the carrier’s operation, cargo, authority type, insurance, and whether the company is operating as a for-hire motor carrier.

Do not assume that Canadian registration alone is enough for U.S.-bound work. Before accepting freight, confirm whether the company needs USDOT registration, MC authority, insurance filings, a process agent filing, or other FMCSA-related setup for the planned operation.

SCAC code

A Standard Carrier Alpha Code, or SCAC, is a carrier identifier used in U.S.-bound customs and transportation workflows. In ACE eManifest, the SCAC is tied to the carrier and is used with trip numbers, shipment control numbers, and PAPS references.

Canadian carriers should confirm that the SCAC used by dispatch, the customs broker, the PAPS label, and the ACE eManifest all match before the driver is released toward the border.

SCAC setup tips

• Register or renew the SCAC before accepting regular U.S.-bound freight.
• Use the same SCAC across PAPS labels, broker paperwork, and ACE eManifest records.
• Train dispatchers not to reuse trip numbers or shipment references.
• Keep broker, carrier, and software profiles updated when company details change.

Bonded vs non-bonded carriers

Bond status affects what kind of U.S. customs movement a carrier can handle. A standard non-bonded carrier may handle freight expected to release at the first U.S. port, while bonded or in-bond movements involve additional customs control, paperwork, and compliance responsibility.

Canadian carriers should confirm whether a load is a standard PAPS shipment, an in-bond movement, or another shipment type before dispatch. Do not accept freight that requires bond authority unless the carrier and paperwork are set up for that movement.

ACE eManifest requirements

ACE eManifest is the U.S. CBP pre-arrival reporting process for commercial highway carriers. Highway carriers bringing goods into the United States have had to comply with ACE Manifest requirements since 2007 by filing an ACE Manifest at least one hour before arrival at the border.

For PAPS shipments, both the ACE Manifest and the customs broker entry number should be on file with CBP for at least one hour before the driver arrives. Missing, late, or unmatched information can result in border delays, refused entry, or penalty action.

ACE data commonly includes

• SCAC and carrier identity.
• Unique trip number.
• U.S. port of entry and estimated arrival time.
• Truck, trailer, VIN, plate, and equipment details.
• Driver name and travel document details.
• Shipment Control Number, often SCAC plus PAPS or bill number.
• Shipment type, such as PAPS, in-bond, free of duty, empty, or another broker-directed shipment type.
• Shipper, consignee, commodity, quantity, and weight details.
• Hazmat details when applicable.

PAPS shipments and broker entry

PAPS is the Pre-Arrival Processing System used for many standard commercial shipments entering the United States by highway. The PAPS barcode label connects the Canadian carrier’s shipment reference to the commercial invoice, customs broker entry, and ACE eManifest shipment record.

If the PAPS number, SCAC, broker entry, ACE shipment, or paperwork do not match, the driver may face delays or secondary processing before the load can proceed.

PAPS workflow

1. Apply a valid BorderPrint PAPS barcode label to the invoice or shipment paperwork.
2. Send the paperwork to the U.S. customs broker before the truck reaches the border.
3. Confirm the broker has submitted and matched the entry.
4. Create and transmit the ACE eManifest through BorderConnect.
5. Provide the driver with the ACE Manifest lead sheet or trip receipt and matching shipment documents.

PAPS resources

ACE Manifest lead sheets

When the driver arrives at the U.S. border, the officer needs a way to connect the truck at the booth with the ACE eManifest that was already transmitted. A PAPS barcode, barcoded ACE lead sheet, or legible trip number can help the officer retrieve the ACE Manifest more efficiently.

For Canadian carriers, consistent lead sheets reduce manual lookup risk by giving drivers a clear, repeatable document to present with invoices, bills of lading, and PAPS paperwork.

• Use high-contrast printing so the barcode scans clearly.
• Avoid shrinking, stretching, or distorting the barcode.
• Do not reuse the same trip or shipment reference for unrelated crossings.
• Keep the driver copy clean, flat, and easy to present at the booth.
• Order printed ACE Manifest lead sheets from BorderPrint if your team wants consistent physical paperwork.

PAPS vs ACE eManifest vs broker entry

PAPS, ACE eManifest, and the customs broker entry are connected, but they are not the same thing. For a typical U.S.-bound commercial shipment, the Canadian carrier is responsible for ACE eManifest reporting, while the U.S. customs broker handles the entry tied to the commercial paperwork.

A common dispatch mistake is assuming that a PAPS barcode label alone means the shipment is ready to cross. In reality, the PAPS number, broker entry, SCAC, ACE shipment, and driver paperwork all need to line up before arrival.

What happens at the U.S. border?

At the first U.S. port of entry, the driver presents identification and the shipment paperwork prepared for the load. CBP can retrieve the ACE Manifest electronically, and a PAPS barcode or barcoded lead sheet can help the officer locate the correct manifest faster.

The officer verifies the reported trip, driver, equipment, shipment, and release information. CBP may release the shipment, refer the driver to secondary inspection, or require additional documentation depending on the load and status.

Shipment types

The shipment type selected in ACE eManifest tells CBP how the goods are expected to enter, release, or move. Choosing the wrong shipment type can create delays, rejection messages, broker mismatches, or secondary processing.

In-bond freight

In-bond freight moves under customs control and generally requires more careful coordination than a standard PAPS shipment. The Canadian carrier should verify the in-bond number, destination, bonded movement instructions, broker or filer responsibilities, and driver paperwork before dispatch.

If the in-bond movement is missing, misreported, or assigned to the wrong carrier or destination, the driver may face delays or corrections at the border.

Common mistakes that delay U.S.-bound trucks

Most border delays are caused by mismatches between the paperwork, broker entry, SCAC, PAPS number, ACE eManifest, lead sheet, port, ETA, driver, or equipment details.

ACE rejection reasons and troubleshooting

An ACE eManifest rejection means the transmitted data needs correction before the carrier should proceed as if the shipment is ready. Dispatchers should treat rejected, incomplete, or unmatched manifests as operational exceptions.

The safest workflow is to correct the rejection, verify ACE acceptance, confirm broker entry status where applicable, and then give the driver updated paperwork before arrival.

Brokered loads and subcontracted carriers

Brokered and subcontracted loads create extra risk because the company selling the freight, the carrier on the paperwork, and the carrier physically hauling the load may not be the same company. Dispatchers should confirm who is acting as the carrier for customs reporting before the load is accepted.

For subcontracted loads, the parties should confirm which SCAC, PAPS number, ACE Manifest, driver, and equipment records will be used before the driver is dispatched.

Port code and ETA accuracy

The U.S. port of entry and estimated arrival time are not just planning details. They are part of the transmitted ACE data and should match the driver’s actual route, dispatch plan, and timing.

If a driver changes crossings, has a major delay, swaps equipment, or changes the arrival plan, dispatch should review the ACE eManifest before the truck reaches the booth.

• Confirm the intended U.S. port before transmitting the manifest.
• Update dispatch notes if the driver changes route or border crossing.
• Use a clear internal process for ETA changes and equipment swaps.
• Keep trip numbers and shipment control numbers separate to avoid reference conflicts.

Documents needed by shipment type

The exact paperwork depends on the shipment type, broker instructions, importer requirements, carrier status, commodity, and port. The table below gives dispatchers a practical starting point for U.S.-bound load planning.

Cargo exemptions and special reporting

Some U.S.-bound movements may involve exemption or special reporting scenarios, but dispatchers should not guess. The carrier should confirm the shipment type, broker instructions, importer requirements, and ACE reporting details before the driver is sent to the border.

CBP penalties and compliance risk

U.S.-bound carriers can face delays, refused entry, or penalty action when ACE eManifest, broker entry, shipment, or driver information is missing, late, inaccurate, or not properly matched.

For PAPS shipments, both the ACE Manifest and the entry number by the customs broker should be on file with CBP before the driver arrives at the border. Dispatch should build in time for broker matching, ACE responses, corrections, and driver paperwork updates.
