Selling to American customers from Europe, Asia, Canada or Australia? The demand is real — but since 2024, and especially since the US ended duty-free de minimis entry in 2025, serving it order-by-order from home has become much more expensive. Most brands stall here, and it's rarely demand that stops them. It's fulfillment. Here's the math on when to move inventory into a US fulfillment center, and how to choose one.
The US is the world's second-largest ecommerce market — behind only China — and by spending power, one of the most attractive on earth: American shoppers generate more online revenue per person than any other major market. Online sales already make up roughly 17% of all US retail and are still growing faster than retail overall, according to the U.S. Census Bureau. What's less obvious is why so many strong international brands plateau the moment they start advertising to US customers at real volume. It's rarely a demand problem. It's almost always a fulfillment problem.
The short version: the fastest, cheapest way to grow in the US is to get inventory physically inside the country before you scale ad spend — not after. Shipping every order internationally from your home warehouse works fine at low volume and quietly becomes unsustainable the moment US orders become a real share of revenue. That's where a US partner for ecommerce fulfillment services changes the math.
What changed: trade costs and US market access
The underlying logic of domestic fulfillment has always been sound. What's changed since 2024 is urgency. Tariff and duty changes have reset the cost of moving goods into the United States, and cross-border ecommerce felt it immediately. When every individual parcel crossing the border carries duty, brokerage, and handling charges, the per-order cost stops making sense at exactly the volume where a brand is starting to win.
The biggest single change was the end of de minimis. For years, parcels worth $800 or less could enter the US duty-free under Section 321, which made shipping every order from abroad cheap and simple. That exemption has been suspended for all countries since August 29, 2025, and in June 2026 US Customs and Border Protection wrote the suspension into its regulations. Every low-value parcel crossing the border is now a formal import with duty attached. Cross-border fulfillment that used to work at 50 orders a day now carries a cost on every one of them.
One of our clients, the Finnish outdoor and military surplus retailer Varusteleka, described the moment plainly: they were fulfilling US orders out of Helsinki when, in their words, the world got dicey with trade uncertainty, and that had a profound effect on their US market. What they wanted was better service and stability for their American customers.
The pattern we keep seeing
Some brands absorbed the new costs. Some passed them to customers and watched conversion fall. And a number shut down US operations altogether rather than keep losing money on every order.
That third group is the interesting one, because many of them are now coming back. They still have proven American demand — they just need a different structure to serve it. Relaunching through a distribution partner lets them re-enter without a lease, a payroll, or a US operation to stand up from scratch.
Who has actually been calling. Across 2025 and 2026, our inbound has come from Australia, Canada, the United Kingdom, and Mexico, across product categories as varied as consumer tech, apparel, medical supplies and equipment, and computer hardware. What they have in common isn't an industry — it's a stage. Each had real US demand, hit a cost or logistics wall serving it from abroad, and preferred to solve it with a partner rather than a subsidiary.
One clarification worth making early
Holding inventory in the US does not make tariffs disappear. Goods still enter the country and duty is still assessed. What changes is when and how: you import in bulk and clear customs once, instead of sending thousands of individual parcels that each trigger their own charges and paperwork. Your customer, meanwhile, stops being charged at the door — which is where most of the damage to conversion and trust actually happens.
Why direct international shipping breaks down at scale
Brands that ship direct-to-consumer from Europe or Asia into the US usually hit the same three walls, in roughly this order:
Delivery times kill conversion
American shoppers are trained on 2–3 day delivery. A 10–14 day international shipment is a checkout-abandonment problem before it's ever a fulfillment problem.
Customs friction erodes trust
Orders shipped direct from abroad can get hit with duties at the door or held in customs — damaging the unboxing experience and generating support tickets.
Cost per order climbs, not falls
International parcel rates don't get meaningfully cheaper with volume the way domestic freight does. At scale, that's a structural disadvantage against every US-based competitor bidding against you.
The math: when does a US 3PL actually make sense?
This is the question every international brand is really asking before they expand ecommerce to the US. Below is an illustrative model — not a quote — showing how the two approaches compare as monthly US order volume grows. Real numbers depend on product size, weight, and origin country, but the shape of the curve holds true across most categories.
*Illustrative model only. International direct cost stays relatively flat per order regardless of volume; the US 3PL cost per order starts high at low volume (fixed import/setup costs spread over few orders) and drops sharply as volume grows. Below ~400 orders/month, shipping direct is often still cheaper — above it, a US 3PL usually wins decisively.
A concrete example
Take a European brand shipping 2,000 orders/month to US customers, direct from a home-country warehouse:
| Approach | Est. cost / order | Est. monthly fulfillment cost | Delivery time |
|---|---|---|---|
| International direct shipping | ~$27 | ~$54,000 | 10–14 days |
| Bulk import + US 3PL | ~$12 | ~$24,000 | 2–3 days |
Illustrative figures for a mid-size parcel; actual per-order cost depends on product weight/size, origin country, and current parcel contracts. A fulfillment partner can run this comparison against your real numbers in about a day.
The takeaway: below roughly a few hundred US orders a month, shipping direct is often still the right call — don't over-engineer early. Once US orders become a meaningful, steady part of revenue, the math flips hard in favor of importing in bulk and fulfilling domestically, on both cost and delivery speed.
The fix: how to expand ecommerce to the US
The standard playbook for international brands moving into a US fulfillment center, once volume justifies it:
Import inventory in bulk
Duties paid once, at bulk freight rates — not per parcel. With international freight shipping handled as one consolidated inbound, this is the step that unlocks everything downstream.
Warehouse it in the US
Inventory sits ready to ship domestically instead of crossing an ocean per order.
Fulfill US orders like a domestic brand
2–3 day delivery, no customs surprises for the customer, domestic shipping rates — with pick-and-pack fulfillment handled stateside.
Keep your home-market fulfillment exactly as-is
This is an addition to your operation, not a migration. Europe/Asia fulfillment runs in parallel, unchanged.
Two brands that made the move
The playbook above is straightforward on paper. What it looks like in practice depends a great deal on the product and the starting point. Here are two international brands who took the same route for different reasons.
Varusteleka
Varusteleka were fulfilling US orders out of Helsinki when trade conditions shifted underneath them. They started looking for a 3PL to expand their presence in the US market properly, and to give American customers the service and stability that shipping from Finland couldn't.
They found us by submitting an inquiry through our website. We called back within the hour — which, it turned out, was the part they remembered:
The partnership is early on. So far it has been visits, planning sessions, and ongoing conversations about establishing the brand and the distribution site, rather than a rush to go live. They've also noted something that doesn't appear on any 3PL capability page: that our team understands there are cultural differences between the US and Finland, and embraces them. Onboarding an international brand isn't only a logistics exercise.
Their own summary of what the partnership unlocks is the clearest answer to why brands do this at all: a US distribution site gives them a foothold in the market, and their American customers get orders faster than anything shipped from overseas without being hassled by import taxes, tariffs, and shipping costs at their end. Better customer experience, and as they put it, happy customers are loyal customers.
R&S is real people. You can pick up the phone and call or send an email and get a response. If there is a question, they ask it and don't assume.
Varusteleka · FinlandZMC
ZMC came to us in 2018, when trade costs first pushed them to rethink how they served American customers. Their product made the move harder than most: aluminum extrusions, much of it in 16-foot lengths, long enough that carriers began adding over-length fees and then declining the freight outright.
Solving it meant building the operation around the product rather than the other way around. We installed cantilever racking sized for the lengths, brought in a four-way combi lift to pick them without damage, and rebuilt the outbound plan as volume grew — from LTL, to hotshot, to three dedicated full truckloads a week.
None of that equipment was in the building before they asked (read the full ZMC case study). That's worth stating plainly, because it's the real question behind any capability page: not what a warehouse already owns, but whether they'll build what your product needs.
One client put it this way: having a US distribution site is a genuine competitive advantage — one they'd rather their competitors didn't figure out.
Why the US Southeast specifically
Location inside the US matters almost as much as being in the US at all. The Southeast — and Tennessee in particular — sits within a one- to two-day ground shipping radius of the majority of the US population, thanks to its position relative to the country's major interstate freight corridors. For a brand shipping nationally, that geographic center of gravity is the difference between a 2-day and a 4-day delivery window to most of your customer base, without paying for air freight. That's the case for an East Coast fulfillment center over a West Coast one for most national brands. And for brands importing by ocean, our Savannah, Georgia location sits beside one of the busiest container ports in the country.
What to look for in a US fulfillment center
If you're evaluating 3PLs for this move as an international brand, the brands that get it right prioritize four things above generic 3PL checklists:
Import/customs experience
A fulfillment partner who has actually handled inbound freight from your region, not just domestic replenishment.
Platform integrations
Direct, tested connections to Shopify, WooCommerce, or Amazon so US orders route automatically without manual work on your end.
Transparent, volume-based pricing
Flat per-order fulfillment costs that don't spike as you scale, unlike international parcel shipping.
Someone who answers the phone
International expansion already involves enough moving parts — entity setup, tax, customs. Across a six-to-ten hour time difference, the gap between a person and a ticket queue is a day lost per exchange. Ask who your point of contact is, and how quickly they respond.
Built for brands expanding into the US
R&S works with international ecommerce brands specifically on this transition — importing inventory, warehousing it in the Southeast, and fulfilling US orders at domestic speed and cost, with direct Shopify, WooCommerce, and Amazon integrations. You don't have to choose between your home market and the US; we're built to run alongside your existing operation, not replace it.

US expansion FAQ for international ecommerce brands
Does using a US 3PL reduce the tariffs I pay?
No, and be cautious of anyone who says otherwise. Goods entering the United States are subject to duty regardless of who stores them afterward. What a US distribution site changes is the structure: you import in bulk and clear customs once, rather than sending thousands of individual parcels that each incur duty, brokerage, and handling charges. The saving comes from consolidation and domestic shipping rates, not from avoiding tariffs.
Can I still ship parcels to the US duty-free under $800?
No. The $800 de minimis exemption (Section 321) has been suspended for all countries since August 29, 2025, and CBP formalized the suspension in June 2026. Low-value parcels are now dutiable imports, which is a major reason international brands are moving inventory into a US fulfillment center and importing in bulk instead.
Who is the importer of record when I use a US fulfillment center?
Usually your company, not the 3PL. Foreign businesses can act as a non-resident importer of record, working through a licensed US customs broker who files entries and handles duty payments on their behalf. The 3PL receives, stores, and ships the inventory once it clears. Confirm the setup that fits your situation with a customs broker before your first shipment.
Do I need a US business entity to use a US fulfillment center?
Not necessarily to start. Many international brands begin by importing inventory to a 3PL under their existing entity and address US tax/entity questions in parallel with an accountant. Fulfillment and entity setup don't have to happen in the same step, but it's worth confirming your specific situation with a tax advisor.
How much volume do I need to justify a US warehouse?
There's no fixed minimum, but the math typically favors a US warehouse once bulk freight plus domestic fulfillment costs less than the per-parcel cost of shipping internationally at your current volume — often in the low hundreds of orders per month. A fulfillment partner can run this comparison for you directly against your real numbers.
Will my customers still get charged duties if I fulfill from a US warehouse?
No. Once inventory has cleared customs and is warehoused in the US, orders shipped to US customers are domestic shipments. Duties are paid once, in bulk, on the import — not per order.
We pulled out of the US market. Can we relaunch through a 3PL?
Yes, and it's one of the more common conversations we're having. Brands that shut down US operations when costs rose usually still have proven American demand; what they need is a structure that doesn't require a lease, a payroll, and an operation to run from abroad. Relaunching through a distribution partner lets you restart with limited inventory, measure real demand and delivery performance, and scale from there.
Can I keep fulfilling my home market the same way I do now?
Yes. Moving US fulfillment stateside doesn't require any change to how you fulfill orders in Europe or Asia — it's an addition to your operation, not a replacement.
Which US region should I choose for a fulfillment center?
Location inside the US matters as much as being in the US at all. The Southeast, and Tennessee specifically, sits within a 1–2 day ground shipping radius of most of the US population, making it a strong default for brands shipping nationally.
What if my product is oversized, heavy, or unusual?
Ask about it early, because many 3PLs quietly cap out around 50–70 lbs. We handle non-standard shipping for products that fall outside standard parcel networks, including 16-foot lengths that require cantilever racking and specialized lift equipment.
Will your fulfillment connect to my existing store?
Yes. R&S connects directly to your storefront so US orders, inventory, and tracking flow automatically, with dedicated integrations for Shopify, WooCommerce, and Amazon.
