Cross-Border Shipping to Canada and Mexico: What U.S. Shippers Need to Know

Canada and Mexico aren't niche international markets for U.S. businesses. They're two of the country's largest trading partners, with nearly $1.6 trillion worth of goods crossing U.S. borders with Canada and Mexico in 2025.

For businesses, that creates plenty of opportunity. But cross-border shipping also comes with requirements you don't encounter when freight stays within the United States. Customs paperwork, tariffs, product classifications and other rules can affect your costs and how quickly a shipment reaches its destination.

The good news? You don't need to become a customs expert to ship across the border. You do need to understand the basics, know where problems commonly occur and work with experienced partners who can help keep your shipments moving. Here's what to know to ensure your cross-border shipping is a success!

What's changed with cross-border shipping?

One of the most significant changes to cross-border shipping involves de minimis, a rule that historically allowed many shipments valued at $800 or less to enter the United States without duties. For shippers, the exemption meant lower costs and a simpler customs process for qualifying imports.

That changed in 2025. After first ending de minimis treatment for certain goods from China and Hong Kong, the U.S. suspended the exemption for shipments from all countries effective Aug. 29, 2025. As a result, goods entering the U.S. from Canada, Mexico and elsewhere can no longer qualify for duty-free treatment simply because the shipment is valued at $800 or less.

How the De Minimis Rules Changed

Date	What Changed
Aug. 29, 2025	The U.S. suspended the $800 de minimis exemption for shipments from all countries.
Feb. 20, 2026	The government confirmed that the de minimis suspension would remain in place. The $800 exemption did not return.
June 24, 2026	U.S. Customs and Border Protection (CBP) put the indefinite suspension into its regulations, reinforcing the change for goods entering the U.S.
July 1, 2027	The de minimis exemption is scheduled to be eliminated under federal law.

What does this mean for shippers?

Shipments valued at $800 or less are no longer automatically exempt from duties when entering the U.S. Depending on what you're shipping, that could mean additional costs and customs requirements. The change can also affect goods returning to the U.S., including customer returns, replacement products and items sent back after repairs.

Cross-border shipping tip: Before shipping goods into the U.S., check the current customs requirements and understand what duties, taxes or fees may apply.

Parcel, LTL or truckload: Which shipping mode makes sense?

Cross-border shipping isn't one-size-fits-all. A few boxes headed to Canada require a very different transportation strategy than several pallets or a truck moving into Mexico.

For U.S. shippers, the three primary options are parcel, less-than-truckload (LTL) and truckload shipping. The right choice depends on the size and weight of your shipment, how much you're sending, your destination and how quickly it needs to arrive.

Here's how the three options compare:

Shipping Mode	Often Best For	What to Know
Parcel	Smaller shipments and individual packages	A practical option when goods can be shipped as individual packages
LTL	Palletized freight that doesn't fill a trailer	Your freight shares trailer space with other shipments, so you pay for only the space you need
Truckload	Larger shipments that require most or all of a trailer	Your shipment gets dedicated trailer space and typically has fewer handling points

Don't choose based on the freight rate alone. Cross-border shipping can include brokerage, duties, taxes and other costs, so consider the total cost as well as transit time and service requirements.

How does freight cross the border?

When freight moves between the U.S., Canada and Mexico, it may stay in the same trailer for the trip (through-trailer service) or be transferred to another trailer at the border (transloading).

Through-trailer service means fewer handling points, which can help reduce the risk of freight damage and delays. Transloading adds a handling step but may provide more carrier and routing options, particularly when different carriers handle the shipment on each side of the border.

Neither approach is always better. What matters is understanding how your freight will cross the border and choosing the service that best fits your shipment, route and delivery requirements.

What documents do you need for cross-border shipping?

Paperwork may not be the most exciting part of international shipping, but it's one of the most important. Customs officials use shipping documents to understand what's crossing the border, where it came from, what it's worth and where it's going. Missing or conflicting information can lead to delays and unexpected costs.

Requirements vary by product and shipment, but here's a good starting point.

Shipping to Mexico from the U.S.

Depending on what you're shipping, documentation may include:

• Mexican customs declaration (pedimento), which provides customs authorities with information about the goods entering the country
• Commercial invoice
• Bill of lading (BOL)
• Packing list
• United States-Mexico-Canada Agreement (USMCA) origin information, when needed to claim reduced or eliminated tariffs on qualifying goods
• Electronic export information or other U.S. export documentation when required
• Product-specific permits or certifications when applicable

Each document plays a role in getting your freight across the border. The commercial invoice provides customs officials with details about the transaction and goods, including their description, quantity and value. The BOL document provides the carrier with the information needed to transport the freight. For shipments entering Mexico, the pedimento serves as the official customs declaration and is typically prepared with the help of a Mexican customs broker.

Accuracy matters across all of these documents. Product descriptions, quantities, values and other shipment details should be complete and consistent. Even small discrepancies can create questions during customs clearance and potentially delay your freight.

Shipping to Canada from the U.S.

When shipping to Canada, essential documentation may include:

• Canada Customs Invoice or the required commercial invoice information
• Bill of lading
• Required customs entry information
• USMCA origin information when claiming preferential tariff treatment
• Additional permits, licenses or certificates for certain products

Before shipping to Canada from the U.S., confirm the requirements with your carrier and customs broker. Getting the paperwork right before pickup is much easier than fixing it while your freight is waiting at the border.

What is an HS code, and why does it matter?

A Harmonized System (HS) code is essentially a standardized way for customs authorities around the world to identify what you're shipping.

Think of it as a product classification system. Instead of relying only on a written description such as "machine part" or "plastic container," customs officials use classification codes to determine exactly what type of product is entering or leaving a country.

Those classifications matter because they can help determine:

• How much duty applies
• Whether the product may qualify for USMCA benefits
• What customs requirements apply
• Whether another government agency regulates the product

The U.S., Canada and Mexico all use the Harmonized System to classify goods crossing their borders. Those classifications help customs officials determine what rules and duties apply to each product.

Why should a shipper care?

The wrong classification can mean the wrong duty amount, a customs delay or other compliance problems. If you're unsure how your goods should be classified, don't guess. Work with a qualified customs professional to determine the appropriate classification.

What does USMCA mean for cross-border shipping?

The USMCA is the trade agreement  among the United States, Mexico and Canada. It replaced NAFTA in 2020. For shippers, one of its biggest benefits is the possibility of reduced or eliminated tariffs on goods that qualify for preferential treatment.

The key word is qualify.

A product doesn't automatically qualify for USMCA benefits just because you're shipping it from the United States to Canada or Mexico. It has to meet specific rules of origin, which determine whether enough of the product or its production comes from within the USMCA region.

Here's a simple example: A product manufactured overseas doesn't become a U.S.-origin product simply because it sits in a warehouse in Texas before being shipped to Canada. That's why determining a product's origin is important before assuming USMCA will eliminate the tariff.

How do you certify that goods qualify for USMCA?

If you want to claim USMCA tariff benefits, you generally need to certify that your goods meet the agreement's rules of origin. Unlike NAFTA, USMCA doesn't require a specific certificate or government form. Instead, the required information can be provided on an invoice or another document that accompanies the shipment.

For businesses that regularly ship the same qualifying goods, one certification can cover multiple shipments for up to 12 months.

Some shipments don't require certification based on their value. For example, goods entering Canada valued at C$3,300 or less generally don't require it. USMCA also provides an exemption for qualifying imports valued at US$1,000 or less, although requirements can vary by country.

The takeaway: USMCA can reduce your costs, but don't assume a shipment qualifies. Verify the product's origin and certification requirements first.

How much does it cost to ship to Canada or Mexico from the U.S.?

There's no single answer because the freight rate is only part of what a cross-border shipment can cost. Weight, dimensions, freight class, distance, transportation mode and service level all affect the shipping cost. Then there are the expenses associated with crossing an international border.

To understand what a cross-border shipment really costs, look beyond the freight rate to your total landed cost: everything you spend to get your goods from their starting point to their final destination.

What's included in landed cost?

Product cost + transportation + duties + taxes + brokerage + surcharges + other border-related costs = total landed cost

Cost	What It Means
Product	Cost or declared value of the goods
Transportation	Parcel, LTL or truckload shipping charges
Duties	Charges that may apply when goods enter another country
Taxes	Applicable destination-country taxes
Brokerage	Cost of customs clearance services
Surcharges	Fuel, carrier or other applicable charges
Other costs	Storage, demurrage, reclassification or expedited services that may apply

Why does this matter?

Suppose one transportation option has a lower freight rate but creates more handling, brokerage costs or delays. Another option may have a higher rate but a lower overall landed cost. Looking at the entire cost gives you a better basis for choosing a shipping mode, setting prices and protecting your margins.

Does USMCA mean my shipment is duty-free?

Not necessarily. Qualifying goods may receive preferential tariff treatment under USMCA. Goods that don't meet the agreement's rules of origin may still be subject to tariffs and duties.

Remember: Where a product ships from and where it originated aren't necessarily the same thing.

DDP vs. DAP: Who pays the import costs?

When goods cross an international border, the buyer and seller need to agree on who is responsible for different parts of the shipment. That's where incoterms come in. These are standardized international trade terms that help buyers and sellers define responsibilities for transportation, risk and certain costs.

Two terms you may encounter are Delivered Duty Paid (DDP) and Delivered at Place (DAP).

	DDP	DAP
Import clearance	Seller is responsible	Buyer is responsible
Duties and taxes	Seller pays applicable import duties and taxes	Buyer pays applicable import duties and taxes
Buyer experience	Costs are generally more predictable	Buyer may have costs due at import
Seller responsibility	Higher	Lower

For B2B cross-border freight, the right choice often depends on the buyer's experience and preferences. A company that regularly imports goods may already have a customs broker and prefer to manage the import process itself. Other buyers may prefer the seller to handle those responsibilities.

The important thing is to agree on those responsibilities before the shipment moves. That helps prevent unexpected costs or delays at the border.

Don't Forget About Cross-Border Returns

It's easy to focus entirely on getting products across the border. But what happens when something needs to come back? Cross-border returns can include much more than ecommerce purchases. Businesses may need to return damaged freight, send products back for repairs, replace warranty items, recover reusable equipment or manage rejected shipments.

Bringing goods back across the border can involve many of the same transportation, documentation and customs requirements as the original shipment.

Before you start shipping internationally, consider:

• Who will arrange and pay for the return?
• What paperwork will be required?
• How will returned goods be classified?
• Can multiple returns be consolidated into one shipment?
• Could previously paid duties qualify for recovery or relief?
• Where will the returned goods ultimately go?

If returns are common, building a process in advance can be much less expensive than treating every return as a new logistics problem.

Other Cross-Border Shipping Considerations

A few other factors can affect your costs, service and customer experience.

Currency and pricing

If you're selling across borders, exchange-rate changes can affect your margins. Consider currency fluctuations when setting prices and estimating your total costs.

Country-specific rules

Products that meet U.S. requirements don't automatically meet Canadian or Mexican requirements. Depending on what you sell, there may be different labeling, safety, environmental or product-specific rules.

Transit times

A domestic shipment can usually keep moving once it's picked up. Cross-border freight has another major step: customs clearance. Inspections, missing paperwork or other customs issues can add time, so build realistic border clearance into your delivery expectations.

Carrier and customs broker coordination

Your carrier transports the freight. Your customs broker helps manage the customs-clearance process. Those roles are different, but they need to work together. Shipment information should be consistent, paperwork should be ready before the freight reaches the border and everyone should know who is responsible for each step.

Cross-Border Shipping Checklist

Before your next shipment to Canada or Mexico leaves the dock, ask:

• Am I using the right shipping mode for this shipment?
• Are my goods classified correctly?
• Have I checked current tariff and customs requirements?
• Are my shipping documents complete and consistent?
• Have I determined whether the goods qualify for USMCA benefits?
• Do the buyer and seller understand their responsibilities?
• Does my customs broker have what they need?
• Do I know my total landed cost, not just the freight rate?
• Have I allowed enough time for customs clearance?
• Do I know what happens if the goods need to come back?
