What Documents Do You Need to Ship Freight From Canada to the US?

Missing or incorrect documentation is the single most common reason freight gets held at the Canada-US border. Not the wrong product. Not carrier issues. Paperwork.

The good news is that cross-border documentation is not complicated once you understand what each document does and why customs officers on both sides of the border need it. The bad news is that a small error on any one of them, a mismatched product description, a missing HS code, an incorrect declared value can stop your shipment and cost you time, money, and, in some cases, a retail delivery window.

What you need, what each document covers, and where businesses most commonly get it wrong.

Bill of Lading

The bill of lading is the foundation document for any freight shipment. It is the contract between the shipper and the carrier, and it is the document that travels with the freight from origin to destination.

For a Canada-US cross-border shipment, your bill of lading needs to include the full name and address of the shipper, the full name and address of the consignee, the port of entry or border crossing point, a description of the goods being shipped, the weight and quantity of the shipment, and any special handling instructions.

The description of goods on the bill of lading must match the description on your commercial invoice. Any discrepancy between these two documents, even a minor difference in wording, can trigger a customs hold at the border.

Commercial Invoice

The commercial invoice is the document that customs authorities on both sides of the border use to assess duties, taxes, and compliance. It needs to be accurate, complete, and consistent with every other document in your shipment package.

A commercial invoice for a Canada-US freight shipment must include:

The date of the invoice and a unique invoice number. The name, address, and contact information of the seller and the buyer. A detailed description of each product being shipped, specific enough that a customs officer can identify what it is and classify it correctly. The quantity of each item. The unit price and total value of each item in the currency of the transaction. The currency being used. The country of origin for each product. The applicable Harmonized System (HS) tariff code for each product. The terms of sale, typically expressed as Incoterms such as FOB or CIF. And any applicable freight, insurance, or other charges.

The declared value on your commercial invoice must reflect the actual transaction value. Under-declaring value is a customs violation with serious consequences. Over-declaring creates unnecessary duty liability. Get it right.

Packing List

The packing list is the detailed inventory of everything in the shipment. Where the commercial invoice covers the financial and trade details, the packing list covers the physical contents.

It needs to include the number of packages or units in the shipment, the dimensions and weight of each package, a description of the contents of each package, and any package markings or reference numbers that correspond to your commercial invoice line items.

Customs officers use the packing list to verify that the physical shipment matches the commercial invoice. If the numbers do not line up, package counts, weights, item descriptions, that inconsistency can flag the shipment for examination.

CUSMA Certificate of Origin (formerly NAFTA)

The Canada-United States-Mexico Agreement replaced NAFTA in 2020. If your goods qualify for preferential duty treatment under CUSMA, meaning they were produced or substantially transformed in Canada, the US, or Mexico, you can claim that preference with a CUSMA Certificate of Origin.

This document certifies that the goods meet the rules of origin requirements under the agreement. When it applies, it can significantly reduce or eliminate the duties your US buyer pays on import.

Not all goods qualify. The rules of origin under CUSMA are specific to each product category and require that a minimum percentage of the product's value was added in a CUSMA country. If you are not sure whether your product qualifies, your customs broker can help you determine eligibility and complete the certificate correctly.

A common mistake here is claiming CUSMA preference for goods that do not actually qualify, or completing the certificate incorrectly and having the preference rejected at the border. Either way, your buyer ends up paying duties they were not expecting.

Canada Customs Invoice (for higher-value shipments)

For commercial shipments entering the US from Canada that are valued above certain thresholds, US Customs and Border Protection may require a Canada Customs Invoice in addition to the standard commercial invoice. This form captures specific information in a standardised format that US Customs uses for assessment purposes.

Your customs broker will advise you on whether this document is required for your specific shipment based on value, product type, and the port of entry being used.

Electronic Export Information (EEI), for high-value shipments

If your shipment from Canada to the US has a value of $2,500 USD or more per Schedule B commodity code, US export regulations require the filing of Electronic Export Information through the Automated Export System. This filing is typically handled by your customs broker or freight forwarder and creates a compliance record with the US Census Bureau and Customs and Border Protection.

Failure to file EEI when required is a US export violation, not a Canadian one, but the consequence is the same. Your shipment does not move.

Importer Security Filing (ISF), for ocean freight

If you are shipping by ocean container from Canada to a US port, the Importer Security Filing, sometimes called the 10+2 filing, must be submitted to US Customs at least 24 hours before the cargo is loaded on the vessel. This is a US requirement for ocean freight specifically and does not apply to road freight crossing at land border points.

For most Canada-US cross-border freight that moves by truck through Windsor, Niagara, or other land crossings, the ISF requirement does not apply. It is worth knowing about if your distribution ever involves ocean movement.

Hazmat documentation, if applicable

If your shipment contains any goods classified as hazardous materials under Transport Canada regulations or US Department of Transportation rules, additional documentation is required. This includes a Dangerous Goods Declaration, proper labelling on packages, and in some cases special carrier authorisations.

If you are not sure whether your product contains any regulated hazardous components, certain industrial chemicals, lithium batteries in electronics, aerosol products, or some agricultural inputs, check before you ship. Undeclared hazmat at the border is a serious compliance violation on both sides.

What your customs broker does with all of this

A customs broker is the professional who takes your shipping documents, verifies their accuracy and completeness, and files the customs entry on your behalf with US Customs and Border Protection. They are the person who knows whether your HS codes are correct, whether your goods qualify for CUSMA preference, and what to do when something in your documentation triggers additional scrutiny.

For anyone shipping freight from Canada to the US with any regularity, a customs broker relationship is not optional, it is fundamental. The cost of professional brokerage is a fraction of the cost of a single border hold that delays a retail delivery window or holds temperature-sensitive product outside a controlled environment for 12 additional hours.
