The Complete Cross-Border Trucking Guide: US • Canada Freight Operations

Everything independent carriers must know regarding SCAC codes, PAPS, PARS, ACE/ACI eManifests, and cabotage laws when hauling between the US and Canada.

Hauling freight across the 49th parallel offers lucrative rate-per-mile premiums, but demands strict adherence to US Customs and Border Protection (CBP) and Canada Border Services Agency (CBSA) regulations.

PAPS vs. PARS: What Every Driver Must Know

PAPS (Pre-Arrival Processing System): Required when hauling freight Southbound into the United States. Your PAPS barcode must be transmitted to the US Customs Broker and accepted in the ACE portal prior to reaching the border.

PARS (Pre-Arrival Review System): Required when hauling freight Northbound into Canada. The Canadian Customs Broker submits the entry to CBSA under your 4-digit Canadian Carrier Code.

Avoid Costly Cabotage Violations

Foreign carriers cannot haul domestic freight within the other country. A Canadian carrier cannot move a load from Chicago to Atlanta, and a US carrier cannot move a load from Toronto to Montreal.

Frequently Asked Questions

What happens if a PAPS barcode is not cleared at the border?
The commercial vehicle will be directed to secondary inspection, resulting in border clearance delays and potential examination fines.
