Cross-Border Ecommerce: Costs Before You Sell Anything
Every store who goes international sits down and builds a budget. Trouble is, hardly anybody builds the right one. They pencil in the freight, tack on the marketplace cut, sit back and admire their neat spreadsheet. And then they spend the next three months watching money slip out through cracks nobody told them about. A little bite in the exchange rate you never see coming. A return that costs more to drag back home than it did to send. A whole month of your best hand doing tax paperwork instead of selling.
Here's the truth of it: cross border ecommerce doesn't usually fail because the big obvious costs were too high. It fails because the real bill is longer than the one you wrote down, and the parts that hurt are the parts you couldn't see coming. So before you put one single product up for sale in Latin America, let's lay the whole thing out on the table.
What Is Cross-Border Ecommerce?
Plainly stated, it's a sale where the buyer's in one country and you're in another. Stripe calls it a real growth strategy, not some side hustle, and the numbers say the same: the market's headed from around $551 billion in 2025 to $2 trillion by 2034. That's not a fad you can wait out. That's the tide coming in.
The idea's easy. The headache starts the second your product crosses a line on a map and picks up duties, taxes, a brand-new shipping chain, a way of paying you've never seen, and a government that figures you already know the rules. Simple to say. Hard to do. That's where most budgets fall apart.
The Challenges Most US Sellers Underestimate
Here's a number worth chewing on. According to DHL, about 60% of American businesses are already selling outside the US, but only 21% of them bother to localize how they do it. Read that again. Most of your competition is shipping overseas without building a strategy that speaks to the people they're selling to. We're talking about language and cultural barriers that can significantly slow down, or even shut down, a whole sales endeavor.
And that word — localize — is where folks mistake a small chore for the whole job. It is not running your titles through a translator and calling it a day. Like we get into over in the real work of listing a product across Latin America, it means matching up your product details to each marketplace's own system, pricing to what people down there can afford, and filling in fields that don't exist on a US listing. Lokalise walks the whole thing step by step, and the honest word from that guide is this is a real journey, not a switch you flip on your lunch break.
Choosing Which Countries to Sell In
Nobody sells to "Latin America." There's no such door. You sell to Mexico, Brazil, Argentina, Chile, or whichever country you have in mind. Each one has its own tax rules, a dominant marketplace, and its own customer expectations. What you're weighing is demand, price range, shipping details, and how much red tape sits between you and your first sale.
Mexico's usually where US business like to start: big, close, and the friendliest to a newcomer. Brazil's the biggest prize and the hardest door to get through, guarded by a tax system that seems built to test your patience. Chile and Colombia round out a smart first go. Our guide to selling internationally online in Latin America lays out the order to do it in, and the top marketplaces to sell in Latin America shows you where the buyers actually are. It's real handy to know before you go shipping a pallet somewhere on a gut feeling.
How To Start Selling Cross Border in Latin America
The case for the region's about as clear as it gets. It's one of the fastest-growing ecommerce markets in the world, people shop on their phones, and it all runs on marketplaces where one seller account puts you in front of millions. Best part? It's wide open. Most US brands either skip it or ship in without ever localizing, which leaves the shelf empty for anybody willing to do it right. That's the same story behind every one of the retail brands entering Latin America that showed up treating the place like a real market and not an afterthought.
The catch is the region's good to those who plan and rough on those who wing it. The question isn't whether you can figure out all these costs yourself. The question is whether you should have to. In Latin America, the costs you forgot are exactly the ones that turn a good product into a money pit.
The Cross-Border Cost Stack, In Order
Before we lay out the costs, a quick cheat sheet: because half the confusion in cross-border pricing comes from everyone using the same words to mean different things.
A few terms worth knowing first:
- De minimis: the value cutoff below which a parcel comes in tax-free (or duty-free). Stay under it and you owe nothing, cross it by a cent and the whole parcel gets taxed, not just the part above the line.
- FOB (Free On Board): the value of the goods by themselves, before shipping and insurance. Brazil and Argentina measure their thresholds this way.
- CIF (Cost + Insurance + Freight): the goods plus what it cost to ship and insure them. Chile and Colombia tax on this, which means your shipping cost gets folded into the taxable base.
- VAT / IVA: the same thing. A sales tax added at import. IVA is just the Spanish name for it.
- ICMS: Brazil's version of that sales tax, set state by state.
- Per parcel, not per item: every money threshold below is measured against the total value of the box, all items added up. A few countries also cap how many units can ride in one parcel. We'll flag those.
Alright. Down here are, in our experience, the costs you should be planning for.
→ Spoiler alert: before that list spooks you off Latin America entirely, know that nocnoc can carry every one of those costs for you.
1. Import duties and taxes
This is the one that varies most by country because the rules aren't just different numbers, they're different systems. Here's the whole region on one screen:
| Country | Comes in free if… | Above that, you pay | Measured on | Watch out for |
|---|---|---|---|---|
| Mexico | Parcel is under $50 and US-made. | Parcels from $50 to $117: flat 17% (duty + VAT + processing combined). Parcels over $117: 19% | Parcel value | The 17% / 19% is an all-in "global rate," not just duty |
| Brazil | Never the case. | If parcel is under $50 you pay ~17–20% ICMS (the Brazilian sales tax). Parcels over $50 pay a flat 60% duty, plus 17–20% ICMS | FOB | The 60% cliff is brutal, so pricing below the $50 line matters. |
| Chile | Never the case. | Parcels under $500 don't pay import duty, but pay a 19% sales tax. Parcels from $500–$3,000 pay a 6% duty on CIF + 19% VAT on CIF + duty. | CIF | No VAT-free threshold at all. Max order $3,000; max weight set by carrier. |
| Colombia | Parcel is under $200, under 6 units and US-made. | Parcels over $200 or more than 6 units: ~5–15% duty on CIF + 19% VAT on (CIF + duty) | CIF | You need to be registered as an importer at DIAN or hire a customs agent for shipments over $1000 USD. |
| Argentina | Never the case. | FOB under $400 pays a 21% VAT + 9.5% internal taxes (by category). FOB over $400: ~16% duty + 21% VAT + 3% statistical tax + 9.5% internal taxes. | FOB | Buyers capped at 5 shipments/year, max 3 units of the same product per parcel. |
The short version: Mexico is forgiving for US sellers, Brazil punishes anything over $50, Chile taxes everything, Colombia is generous if you stay under the unit cap, and Argentina limits how often a single buyer can order from you.
2. Freight and last-mile
The cost everybody remembers, covering the trip across the border plus getting it to the door. Ship single parcels out of the US the easy way, on an express courier like DHL or FedEx, and you're looking at roughly $50 for a 1kg package, climbing toward $140 by the time you hit 10kg. Do that on every order and it eats you alive. Move goods in bulk into the region instead (LTL freight runs about $0.15–$0.45 per kilo) and then hand the last leg to local carriers, and your per-order cost drops through the floor.
The other half of the bill is that last mile, and it doesn't cost the same everywhere: a delivery in Mexico City or São Paulo is quick and cheap, while getting a box out to rural Colombia or the interior of Argentina is a whole different story. The cross-border logistics into Latin America breakdown gets into why that last mile is where the surprises hide.
3. Returns
Return rates run 15–30%, and dragging a product back over the border can cost more than sending it out did. Budgeting your returns at zero can cost you your whole operation.
Each country has consumer-protection laws that give buyers a window to send things back:
- Mexico: 5 business days after delivery to cancel.
- Brazil: 7 days after receipt.
- Chile and Argentina: 10 days after receipt.
4. Currency
When your local-currency money turns back into dollars, a few points get shaved off in the rate instead of shown to you straight. On thin margins, those few points are your margin.
5. Marketplace commission
Places like Mercado Libre take a cut by category, usually 10–20%, sometimes with tiers and shipping thresholds stacked on for good measure.
6. Paperwork time
The cost no spreadsheet has a box for: the weeks your team spends on tax setup, importer registration, and filing. That's payroll spent making paperwork instead of making sales.
The whole stack, at a glance:
| Cost | What to budget for | Who carries it when you go alone |
|---|---|---|
| 1. Import duties and taxes | From 0% up to a flat 60% duty, plus 16–21% VAT, IVA or ICMS, depending on the country and parcel value | You |
| 2. Freight and last-mile | ~$50 (1kg) to ~$140 (10kg) per parcel by express courier, or ~$0.15–$0.45 per kilo in bulk LTL, plus a last mile that costs more outside big cities | You |
| 3. Returns | 15–30% return rates, with return shipping that can cost more than the trip out, inside 5–10 day legal windows | You |
| 4. Currency | A few points shaved off every conversion back to dollars | You |
| 5. Marketplace commission | Usually 10–20% per sale, by category, sometimes with tiers and shipping thresholds | You |
| 6. Paperwork time | Weeks of team time on tax setup, importer registration, and filing | You |
How a Cross-Border Ecommerce Platform Changes the Math
Run your eye down that last column. See how nearly every cost lands on you, including the two meanest ones, paperwork and returns. That's right where a marketplace integrator in Latin America changes the whole picture. It's the difference between a cross border ecommerce platform that just puts your listings up and one that takes the parts of the bill you don't want to handle.
When working with nocnoc, there is only one thing you have to decide: how much do you want to charge per item. That's it. No hidden fees. No strategic conversations. We take care of everything else.
nocnoc stands in as the importer of record, handles the tax and compliance filing, holds your inventory down there, runs your returns through local centers, and keeps your listings lined up across every big marketplace from one screen. You keep the margin you actually planned on, because the costs that usually slip away get carried by your partner instead of by your team.
