Remember those long weeks of waiting for customs paperwork and deliveries? Those days are over. In addition to Amazon and Walmart, major shipping carriers are now handling cross-border logistics more efficiently.

Just moving products across borders isn’t enough. You need real strategies. Create smooth shopping experiences for international customers. Provide reliable customer support. Offer payment options that make sense locally.

With cross-border operations between Canada and the U.S., our North American logistics network makes it easier than ever to keep your business running smoothly from coast to coast. 

You’re looking at significant unrealized revenue, and all you have to do is to ensure that your products reach across the border. 

So, how massive is this cross-border opportunity? 

Well, trade between the United States and Canada hit $52 billion in 2023. Cross-border transactions are growing 18% faster than domestic online sales. And this trend extends beyond North America.

According to a report published by Juniper Research, international e-commerce will nearly double in size, from $1.6 trillion in 2023 to $3.3 trillion by 2028. While you’re competing in crowded U.S. markets, Canadian shoppers are spending 23% more per transaction than their American counterparts.

Most sellers tend to overlook this profitable opportunity. In today’s marketplace, market expansion is no longer optional; it’s essential.

Learn in detail about shipping costs for cross-border transactions if you are an Amazon or Walmart seller.

US-Canadian Market Dynamics and Strategic Opportunities

The best way to do cross-border shipping between Canada and the United States opens the gateway to a convenient entry point for e-commerce companies for global expansion.

Crossing this border is easier to sell through than entering distant markets, due to established trade alliances, good transport infrastructure, and buyers with similar buying habits.

However, businesses must still navigate market differences, build the right operational foundation, and address competitive challenges to achieve meaningful results.

The proximity and familiarity between these neighboring markets shouldn't mask the real work required. Companies need to understand regional preferences, establish proper fulfillment capabilities, and develop strategies to stand out in competitive landscapes. 

While the Canada-U.S. corridor offers advantages over more complex international expansions, success still demands thoughtful preparation and execution.

Essential key marketing data

Canadian market size

Analysts estimate that Canada's online retail market could reach $81.5 billion by 2032, having generated about $39 billion in the previous year.

Platform Competition and Market Control

Amazon's Electronics Dominance

Amazon controls approximately half of all online electronics sales in the U.S., giving it significant influence over pricing and customer expectations.

Different Market Conditions

The way business works varies between the two countries, so sellers need different approaches for each market.

What It Takes to Succeed

Running a successful cross-border operation requires good inventory tracking, reliable shipping partners, and understanding how each platform works.

How To Do Cross-Border Shipping as an Amazon/ Walmart Seller

This can help businesses compete globally without spending huge amounts on their international shipping systems. Sellers can use these platforms' warehouses and delivery services to send products worldwide.

Possible methods:

  • Amazon FBA Export fulfills international orders on autopilot
  • Walmart's container transport from China to US warehouses
  • Collaborate with international shipping firms
  • Directly send packages to overseas customers
  • Establish seller accounts across several different countries

How Cross-Border Amazon FBA operates

With Amazon's FBA Export program, sellers don't have to do any additional work to ship goods to customers globally. When someone in another country buys a product, selling on Amazon FBA in Canada and the U.S picks it from its warehouse and ships it overseas. 

The buyer sees all costs upfront, including shipping and import fees.

For bigger international expansion, sellers can use Amazon's Global Selling program. This means storing products in Amazon warehouses in Europe and other regions. Sellers must handle tax registration in each country first.

Amazon takes care of customs forms, tracking, and delivery. They spread inventory across different warehouses to speed up delivery and keep shipping costs lower for customers.

Step 1: Getting Your Business Set Up

Before you can start selling, you need to register on the right Amazon site, Amazon.ca if you're targeting Canada or Amazon.com for the US. 

This means getting your tax paperwork in order and setting up your bank account so Amazon can pay you. 

You'll also want to spend time looking at what other sellers charge for similar products and think about how you'll handle customer questions when they come in.

Step 2: How to Receive Your Items (From Canada into the U.S.)

So, you’ve figured out what’ll sell south of the border and when folks will be looking for it. Now comes the part where you get your stuff across the line and into Amazon’s U.S. warehouses without a big headache.

Get Your Products Ready on Our Side

Before you send anything, double-check Amazon.com’s FBA requirements. They’re a bit different from Amazon.ca.

  • Anything with a best-before date needs it to be printed and easy to read.
  • Make sure every unit has its FNSKU label so Amazon knows it’s yours. You can do it yourself or pay Amazon to do it, but keep in mind they’ll charge you per item.
  • If you’re bagging items, toss on a suffocation warning.

Set Up Your Shipment in Seller Central (U.S.)

You’ll need to be logged into your Amazon.com seller account, not the .ca one.

  • Print the shipment labels they give you, stick ’em on the boxes so customs and Amazon both know what’s what.
  • Tell Amazon what you’re sending and how much.
  • They’ll tell you which U.S. warehouse wants it.

Figure Out How You’re Crossing the Border

You’ve got a few choices here:

  • Book a courier like UPS, FedEx, or DHL
  • Hire a freight forwarder if you’re shipping big pallets.
  • Or, if you’re a glutton for paperwork, you can self-clear, but most folks just pay a broker.

Whoever you pick will need:

  • A commercial invoice (what’s in the boxes, how much it’s worth, where it’s made).
  • A packing list (so they don’t have to guess).
  • Your Amazon shipment ID

Deal with U.S. Customs

  • Make sure you’ve got the right HS codes for your products, this decides your duties.
  • If your goods are Canadian-made, the USMCA might mean zero duty, but you’ll still need to prove origin.
  • The broker or courier files everything with U.S. Customs and Border Protection, so your shipment doesn’t end up in some warehouse limbo.

Get It to Amazon’s Door

  • For smaller shipments (think a few boxes), the courier just drives it right to the Amazon dock.
  • For pallets or truckloads, your carrier will need to book a delivery appointment with Amazon’s system.
  • Once Amazon scans your boxes in, you’ll see “Receiving” in Seller Central — then it’s just a matter of waiting for the stock to go live.

Quick Tip:

If you ship regularly from Canada to the US, open a US Importer of Record account with a broker to avoid delays. Without it, you risk packages being held at the border until the courier sorts out the paperwork.

Step 3: Amazon Takes Care of the Heavy Lifting

Once you’ve sent your products off to Amazon’s fulfilment centres, they spread them out across their warehouses so they’re nice and close to your customers. 

That way, when someone orders, Amazon ships from the nearest spot.

From your side, it’s pretty straightforward:

  • Before the sale: You send your products in bulk to Amazon, following their prep and labelling rules.
  • When the order comes in: Amazon handles the picking, packing, and shipping, you don’t have to run to the post office or chase down couriers.
  • If there’s an issue: Amazon’s local team will deal with returns and customer questions in the buyer’s language, during regular business hours.

Why this works well for Canadian sellers:

  • Faster delivery: Local warehouses mean customers aren’t left waiting weeks for their order to cross the border.
  • Lower shipping costs: You’re sending inventory in bulk, so you skip those expensive one-by-one international shipments.
  • Prime boost: That little Prime badge builds trust and helps turn browsers into buyers.
  • Less hassle with customs: Amazon deals with the tricky cross-border stuff for you.
  • Easy to grow: Need to sell more? Just send more stock no need to rent extra storage or hire more staff.
  • With FBA, you get to focus on finding great products and growing your business, while Amazon handles the shipping, customer service, and returns, from here to there, coast to coast.

Walmart's Increasing Global Reach

Walmart introduced cross-border shipping in 2024, transferring big containers from China to America. The service links Chinese factories with Walmart's US distribution centers, making it easier for sellers to deliver goods to American consumers.

Delivery times vary by location. West Coast deliveries take around 40 days, Midwest shipments need 50 days, and East Coast orders require 58 days.

Walmart gets better shipping rates than most companies, saving sellers money on transportation costs.

Walmart Marketplace International is expanding into more countries, letting sellers list products in the US, Mexico, Chile, and Canada through one account. 

Their fulfillment service now moves shipments straight from Chinese ports to US warehouses, eliminating extra handling steps and reducing costs for sellers.

Walmart Cross-Border Opportunities

Walmart Fulfillment Services (WFS):

  • Growing sophistication in fulfillment capabilities
  • Competitive alternative to Amazon FBA
  • Strong brand recognition in North American markets
  • Potentially lower competition in certain categories

Key Advantages:

  • A less saturated marketplace compared to Amazon
  • Strong offline brand recognition
  • Competitive fee structures
  • Growing customer base seeking alternatives to Amazon

Cross-Border Freight Shipping Navigation

As we move further into cross-border freight shipping, we're venturing into a universe of factors that have nothing to do with just tossing an e-commerce fulfillment package in the mail.

Freight shipping is most relevant when you are sending larger volumes of goods to replenish inventory in FBA warehouses.

Cross-Border Freight Types

Amazon FBA Freight

  • Around: 10000-30000 units per FTL shipment, weekly LTL cycles
  • Products: Electronics, books, housewares, seasonal items like (holiday décor, winter apparel, BBQ gear, school supplies)
  • When to use: Holiday rush air freight (Oct–Dec), steady sellers LTL, big & bulky or multi-package shipments
  • Where: 185+ fulfillment centers, California/Texas hubs primarily

Walmart Supply Chain Freight

  • Around: 25000-80000 units per FTL shipment, bi-weekly cycles
  • Products: Groceries, pharmacy, auto, apparel
  • When to use: FTL for bulk food, air freight for stock-outs
  • Where: 150+ distribution centers, regional grocery hubs

Difference: Amazon sends smaller, quicker batches for variety. Walmart sends in higher volumes for cost efficiencies.

Cross-Border Shipping Guidelines - Amazon 

1. Paperwork You’ll Need

  • Make sure every item has a scannable 1×2-inch label - neat and easy to read.
  • Fill out commercial invoices clearly and accurately.

2. Customs & Duties

  • Use the proper classification for your products when shipping internationally.
  • Put down the right value - fudging numbers can cause delays at the border.
  • Check the duty rules for both Canada and the country you’re shipping to.

3. Size & Weight (General Shipping)

  • Nothing longer or wider than 108 inches.
  • Keep it under 70 lbs per package.

4. If You’re Shipping to an Amazon Fulfilment Centre

  • Boxes shouldn’t be bigger than 25 inches on any side.
  • Keep weight under 50 lbs, unless it’s a single big item that’s meant to be oversized.

Walmart Shipping Guidelines

Required Documents

Walmart needs a freight bill of lading for every shipment, one per location only. Don’t combine shipments from different places. You must also have a GS1 Company Prefix to generate GTINs and UPCs for product setup.

Product Labeling

Each product must have a readable barcode, either a 12-digit UPC or a 14-digit GTIN, on the outer packaging. Unscannable labels will delay shipments.

Packaging Rules

No branding from other marketplaces or fulfillment centers. For warehouse shipments, use 40" x 48" 4-way, Grade A solid-wood pallets. Max 2,100 lbs and 72" height.

Shipping Deadlines

Orders must ship within two business days. No delays unless pre-approved. The timer starts as soon as you receive the order.

International Shipping & Customs

Make use of accurate valuations and classification codes. Recognize duty rates and abide by import/export regulations in both nations.

Time Planning

Plan for peak seasons, weather, and customs delays; they can all impact your tight two-day shipping window.

The main difference between these retailers is clear: Amazon gives you more flexibility with processing times, while Walmart demands faster turnaround. Both demand strict documentation and labeling attention, but Walmart's two-day rule makes planning more important.

Locating the Right Cross-Border Shipping Solutions

Modern cross-border shipping relies heavily on technology to manage complex global logistics networks. The right technology tools can transform what was once a complicated, mistake-prone process into a smooth, automated operation.

Core Technology Solutions

  • Shipping Management Platforms

These systems help businesses compare rates from multiple carriers, automatically choose the best shipping option, and track packages in real-time across different providers.

  • Inventory Management Systems

These platforms track stock levels across multiple warehouses and locations, automatically trigger reorders when inventory runs low, predict future demand based on market trends, and connect directly with online marketplaces and sales channels for seamless operations.

Key Benefits of Automation

Fewer Mistakes 

When software handles documentation and compliance checks, human errors drop significantly. This means fewer delays, fines, and customer complaints.

Lower Costs 

Smart routing algorithms find the most cost-effective shipping methods, while automated carrier selection ensures businesses always get competitive rates.

Time Saving 

Staff no longer spends hours on repetitive tasks like manually creating shipping labels. They can focus on more strategic work instead.

Easy Growth 

Automated systems handle increased shipping volumes without requiring proportional increases in staff. A business can ship 10 times more packages without hiring 10 times more people.

Better Compliance 

Automated checks catch regulatory issues before shipments leave the warehouse, reducing the risk of penalties and rejected packages.

Cross-Border Industry Difficulties and Solutions

Let's outline the real cross-border shipping problems you'll face and provide workable freight solutions for each.

Difficulties with Regulatory Compliance

Best Practices for Navigating Product Restrictions:

  • Before expanding, research destination country regulations.
  • Maintain up-to-date databases of commodities that are restricted.
  • Work together with compliance specialists for intricate product categories.
  • Integrate automated restriction verification into your systems.

Documentation Needs:

  • Invest in platforms for automated documentation.
  • Maintain templates for common shipment types.
  • Educate staff on proper documentation practices.
  • Build connections with customs brokers

Currency and Financial Hazards

Best Practices for Handling Exchange Rate Changes

  • Use hedging techniques when dealing with significant exposures.
  • Use dynamic pricing to account for changes in exchange rates.
  • Where possible, the price is given in local currency.
  • Regularly check rates and make necessary adjustments.

Payment Processing:

  • Collaborate with payment processors that accept a variety of currencies.
  • Understand the customs of international payments
  • Use fraud prevention when making payments abroad.
  • Consider the target markets' local payment options.

Issues with Customer Service

International Returns:

  • Provide comprehensive return guidelines for clients from other countries.
  • Where possible, provide pre-paid return labels.
  • Consider nearby facilities for processing returns.
  • Clearly explain the return procedures.

Language and Cultural Constraints:

  • Provide local languages for customer service.
  • Recognise cultural norms and desires
  • Adapt your communication style to the norms in your area.
  • Give precise shipping and delivery information.

Regulatory and Tax Concerns

International e-commerce requires navigating different regulatory and tax structures. For international operations to be sustainable, proper planning and compliance are essential.

US-Canada Trade Benefits

The USMCA agreement gives businesses real advantages when trading across borders. Companies can get reduced tariffs on products that qualify and enjoy faster customs processing. 

But products must meet origin requirements like usually 40-75% North American content is depending on what you're selling.

Sales Tax Basics

United States

Every state has its own sales tax rules. Since the 2018 Wayfair court case, businesses must collect sales tax in states where they sell more than $100,000 or have 200+ transactions per year. Tax rates go from 0% to over 10%, depending on where you're selling.

Canada

Federal GST runs 5%, plus provincial taxes that vary by province. Foreign businesses must register for GST/HST once they sell more than $30,000 yearly. Quebec has its own separate provincial tax system.

Product Standards

US Requirements 

Different government agencies watch over various products - the FDA handles food and medical devices, the CPSC covers consumer goods, and the FCC manages electronics. Many products need approval or testing before you can sell them.

Canadian Requirements 

Health Canada oversees food, drugs, and consumer products. Most items need CSA certification or similar safety marks. Consumer products must show information in both English and French.

Business Setup

Companies can work through subsidiaries, branches, or representative offices. Each option has different tax and legal effects. Most business activities need specific licenses or permits in both countries.

Main Compliance Steps:

  • Register your business where needed
  • Get the required operating licenses
  • Keep proper company records
  • File yearly returns as required
  • Maintain detailed records for customs and taxes

Working with local tax and legal experts helps you handle these requirements while avoiding expensive mistakes. Due to the complexity of cross-border business, expert advice is essential for success.

Building Customer Trust Across Borders

International customers often have additional concerns about ordering from foreign sellers. Addressing these concerns proactively is crucial for success.

Trust-Building Strategies

Transparent Communication:

  • Provide clear freight shipping time estimates
  • Explain any additional costs upfront
  • Offer multiple communication channels
  • Respond promptly to customer inquiries

Local Presence Indicators:

  • Use local fulfillment where possible
  • Provide local customer service numbers
  • Display local currency pricing
  • Offer familiar payment methods

Reviews and Social Proof:

  • Encourage customer reviews and ratings
  • Showcase successful international deliveries
  • Highlight positive customer experiences
  • Address negative feedback promptly and professionally

Cultural Adaptation

Market Research:

  • Understand local shopping preferences
  • Adapt product descriptions and imagery
  • Consider seasonal and cultural factors
  • Research local competition and pricing

Localization Efforts:

  • Translate product listings and communications
  • Adapt marketing messages for local audiences
  • Consider local holidays and events
  • Understand return and exchange expectations

FAQs

1. What is Amazon's cross-border e-commerce?

Amazon's cross-border program lets you sell products to customers in other countries through their international websites. 

2. How does cross-border shipping work for e-commerce?

A customer in another country orders your product and receives it for shipment. When the package passes through customs, officers inspect its contents and collect taxes. The customer then receives delivery by local postal services. 
Customs paperwork that details the item you are sending and its value must be filled out. The entire procedure usually takes 1 to 8 days.

3. Is cross-border shipping profitable for e-commerce sellers?

Yes, but profits per item are lower due to shipping costs. However, you reach a million more potential customers worldwide. 

It works best when you sell unique products that people can't find locally. Most sellers use international shipping to grow their business rather than to maximize immediate profits.

4. What are the three types of e-commerce?

Business-to-Consumer (B2C) refers to companies selling directly to individual customers, such as buying shoes from Nike’s website. Business-to-Business (B2B) involves companies selling products or services to other companies, like office supply wholesalers supplying businesses. Consumer-to-Consumer (C2C) describes individuals selling to other individuals, for example, selling used items on eBay or Facebook Marketplace.
