What Selling on Amazon Canada and Mexico Actually Takes

Amazon makes it easy to flip on Canada and Mexico from your existing US listings. That ease can be deceptive. The tools are familiar, but the costs, compliance obligations, and margin math are not the same business you’re running in the US, and each layer below adds its own cost before you sell a single unit.

In this post, we’re covering the six cost and compliance layers that determine whether Canada and Mexico are worth pursuing: 

1. Registration and tax obligations
2. Fulfillment tradeoffs
3. The real margin math
4. Packaging and labeling rules
5. Localization
6. The back-office overhead most sellers don’t budget for.

1. Registration and tax obligations come before the listing does

Before you ship anything to Canada, you need to figure out who’s legally responsible for bringing the goods into the country (known as the “importer of record”) and get set up with Canadian customs. Most sellers hire a customs broker to handle this instead of doing it themselves. Separately, you’ll need to sort out Canada’s sales tax (GST/HST): whether you’re required to register for it, and who’s actually responsible for collecting and remitting it. Just because Amazon collects some taxes on your behalf as the marketplace doesn’t mean you’re off the hook for your own tax obligations.

Mexico requires more paperwork upfront. You’ll need a Mexican tax ID (called an RFC), a seller classification, and your bank details on file. Without all three, Amazon can’t give you an accurate picture of what you’ll actually get paid. And a new tax law that took effect in 2026 changed how much Amazon withholds from seller payouts, including for registered businesses. Having an RFC doesn’t mean nothing gets withheld, and on top of that withholding, Mexico’s VAT (their version of sales tax) is a separate cost you still have to account for.

None of this is optional paperwork you can backfill after launch. Get it wrong and you’re dealing with withheld payouts or blocked shipments, not a slow ramp.

2. Fulfillment: pick your tradeoff, not your default

There are two ways to actually get your product to customers in these countries, and each comes with tradeoffs.

The easier option is Remote Fulfillment with FBA, sometimes called NARF. Amazon ships these orders straight from your existing US inventory, and the customer pays any import duties themselves at checkout. It’s the lower-commitment choice since you don’t need to move any inventory across the border. But it’s not free of downsides. Not every product qualifies, there’s fees to consider, and you need to check what delivery date the customer actually sees on the listing. If it’s slower than what a local seller can offer, that alone can cost you the sale. 

The other option is Local FBA: you import your inventory ahead of time and store it in warehouses inside Canada or Mexico. This gets products to customers faster and can lower your cost per order, but it comes with real downsides too. You’re now running a second inventory operation to keep those warehouses stocked, you’re tying up cash in a market you haven’t proven out yet, and you’re paying separate freight and import costs to get the stock there in the first place.

Neither option is automatically the better choice. The right one depends on your product’s margins, which is what we’ll get into next.

3. The margin math is worse than a currency conversion

In order to get an accurate pricing model, you need to build out what it costs to sell that specific product through that specific fulfillment method, all added up in one currency: what the product costs you, Amazon’s fees, shipping it into their warehouses, storage, returns, advertising, any promotions, and the cost of converting currency. On top of that, add import duties and any taxes your business has to eat rather than pass along.

One thing to keep separate: taxes that get withheld or that you can eventually recover aren’t a real cost; they’re your money, just temporarily tied up. If you lump those in with your actual costs, you’ll get a distorted picture.

4. Packaging and labeling are legal requirements, not a translation task

In Canada, most packaged non-food products need to show what the product is and how much is in it in both English and French. The company name and address can be listed in just one of the two languages, but Quebec has its own extra rules on top of the federal ones, and certain product categories have additional requirements of their own. 

In Mexico, your packaging needs to be in Spanish and meet whatever official product standard (called a NOM) applies to your category, and those standards differ depending on what you’re selling. Just translating the title on your Amazon listing doesn’t mean the actual physical product is allowed into the country. Customs cares about what’s on the package, not what’s on the webpage. 

Get this sorted before you ship any inventory. If your packaging doesn’t meet the requirements and you find out after it’s already sitting in a fulfillment center, fixing it at that point is slow and expensive.

5. Localization costs more than the listing tools suggest

Amazon has a tool called Build International Listings that can automatically copy your US listings over and adjust pricing for exchange rates and some fee differences. That’s helpful for saving setup time, but it won’t tell you whether customers will actually want to buy what you’re selling.

For Mexico, that means having someone fluent in Mexican Spanish actually review your title, bullet points, images, and A+ content, not just run it through translation software. It also means researching what people in Mexico actually search for, instead of translating your US keywords word-for-word. Those aren’t always the same thing.

For Canada, it means checking that you meet French-language requirements, that measurements are in the units Canadians expect, that spelling matches Canadian English conventions, and that your warranty terms actually apply there. It also means removing any claims or promotions that only make sense in the US.

And advertising needs its own plan and its own budget for each country. Your ad campaigns won’t perform well just because they work in the US. You need to research local search terms and build these out separately from day one.

6. The back-office cost that gets missed

Selling in multiple currencies changes your bookkeeping in ways most sellers don’t think about ahead of time. Converting currencies, reporting foreign taxes, and tracking your cost of goods sold across different currencies usually means you’ll need to upgrade your accounting software. Make sure ongoing expenses like these are actually built into your cost model, not treated as an afterthought.

Where the math actually works

Expansion pays off when three things are true at once: your landed cost and local price leave real contribution margin after every fee, tax, and return is counted; your product’s registration and labeling requirements are resolved before stock ships, not during a compliance problem; and the back-office and advertising overhead is sized against the volume these markets will realistically produce, not your US numbers. Any one of these can be fixed. All three failing at once is what turns a promising market into a line item that quietly loses money every month. Do the cost model first to ensure entering these marketplaces is the right move for your business.
