Cross-Border Freight Compliance: A Shipper's Guide to US–Canada Transport
US–Canada cross-border freight moves over $2 billion in goods every day, yet it remains one of the most misunderstood shipping lanes in North America. Customs delays, missing documentation, and broker miscommunication can turn a 48-hour transit into a week-long headache. Here's what every shipper needs to know before their first cross-border load.
PAPS and PARS: The Core Numbers
Every cross-border shipment needs a pre-arrival processing number. Southbound (Canada to US) shipments use PAPS — Pre-Arrival Processing System. Northbound (US to Canada) shipments use PARS — Pre-Arrival Review System. These bar-coded numbers are assigned by the customs broker and must appear on the bill of lading before the truck reaches the border. Missing or incorrect PAPS/PARS numbers are the single most common cause of border delays.
Required Documentation
Every cross-border shipment requires: a commercial invoice (shipper, consignee, full description of goods, HS tariff codes, declared value, and country of origin); a bill of lading; a packing list; and the PAPS or PARS bar code. For certain commodities — food, chemicals, textiles, and goods subject to USMCA preferential treatment — additional certificates of origin or FDA prior notice filings may be required. Your customs broker should review the commodity list before the first load moves.
Choosing a Customs Broker
A licensed customs broker is not optional — they are the legal agent who files your entry with CBP (US) or CBSA (Canada) on your behalf. Choose a broker with experience in your commodity category and one who can file electronically 24/7. Many border delays happen not because of the carrier, but because the broker filed late or used an incorrect tariff code. CargoNet works with a vetted network of cross-border brokers and can make introductions for shippers who don't yet have a broker relationship.
Driver and Equipment Requirements
Cross-border drivers must hold a FAST card (Free and Secure Trade) or be prepared for standard secondary inspection, which can add 2–4 hours to transit. Equipment must meet both US FMCSA and Transport Canada safety standards. CargoNet's cross-border fleet is maintained to dual-compliance standards, and all drivers in our cross-border division hold current FAST cards.
