Selling online to the USA is an attractive option as your eCommerce business scales. With a population of over 330 million, strong consumer spending, and a market that’s already comfortable buying from overseas brands, the opportunity is clear.
But selling in the USA from the UK isn’t as simple as switching on global shipping and hoping for the best. From longer delivery distances and higher shipping costs to customs checks and different customer expectations, there are a few extra moving parts to get right. Miss them, and you’ll quickly feel it in delayed orders, rising costs or unhappy customers.
How Selling Online to the USA Compares to Selling in the UK
At first glance, selling to customers in the USA might feel similar to selling in the UK. You’re still operating in English, using familiar eCommerce platforms like Shopify or Amazon, and dealing with customers who have similar online shopping habits.
But under the surface, there are a few key differences that can catch brands off guard if they’re not prepared.
Quick View of Differences Between UK vs USA eCommerce
| Factor | UK Customers | US Customers |
| Preferred marketplaces | Amazon, eBay and Shopify stores | Amazon dominates, plus Walmart, Shopify stores |
| Tax | VAT included in product price | Sales tax varies by state and is added at checkout |
| Returns expectations | Structured returns, often stricter policies | Easy, low-friction returns expected as standard |
| Payment methods | Debit/credit cards, PayPal, Klarna, Apple Pay | Credit cards dominate, plus PayPal, Apple Pay |
| Delivery expectations | 2-3 working days are widely accepted | Faster delivery expected, even from overseas |
| Fulfilment costs | Lower domestic shipping costs | Higher shipping costs due to distance and zones |
What Changes When You Start Selling in the USA
Customer Expectations
US consumers are used to a smooth, predictable online shopping experience. That means clear communication from the moment they place an order. They want to know when it’s arriving, how it’s being delivered, and where it is at every stage.
Tracking updates, accurate order confirmations, and proactive communication all play a big part in building trust, especially when buying from overseas brands. If that visibility isn’t there, customers are far more likely to raise queries or lose confidence in the purchase.
Returns Expectations
Returns are a bigger deal in the US market, with approximately 24.5% of all online sales ending in a return. Customers expect the process to be simple, quick, and easy to understand. If it feels complicated or expensive, they’re more likely to think twice before buying in the first place.
For UK brands shipping internationally, this can get tricky. Sending items back across borders isn’t cheap, so having a clear and manageable returns setup is important if you want to keep customers coming back.
Pricing Perception
Pricing works a little differently, too. UK-based customers are used to seeing Value Added Tax (VAT) included upfront. In the US, extra costs like sales tax and shipping are often added at checkout. That means your pricing needs to be clear, with no surprises at the final step.
Unexpected fees, especially duties or shipping costs, are one of the quickest ways to lose a sale. Nobody enjoys getting to checkout and feeling like the total has suddenly shot up.
Shipping to the USA from the UK: What You Need to Get Right
Shipping is where most of the real challenges sit when entering the US market. It’s also where customer experience is won or lost.
Delivery Times
Shipping from the UK to the US will take longer than domestic orders, so the focus is on getting the balance right between cost and reliability, not chasing the fastest option.
In reality, most US shoppers are willing to wait. Over 80% will still complete a purchase if delivery takes four to seven days, as long as shipping is free, and more than 95% prefer free standard delivery over paying for faster shipping. Only a small percentage prioritise speed above everything else.
That means consistency matters more than speed. Clear delivery estimates, reliable services, and hitting the timeframes you set are what keep things running smoothly. If customers know what to expect and you deliver on it, longer delivery times become far less of an issue.
Shipping Costs
International shipping isn’t cheap, and trying to cut costs too aggressively can backfire. Lower-cost services often mean longer delivery times, less reliable tracking and a higher risk of delays. That might save a few pounds upfront, but it can cost you in refunds, complaints, and lost repeat business.
You need to strike a balance between cost and service so your customers feel they’re getting a fair deal.
Carrier Choice
Relying on a single carrier can be limiting, especially when shipping internationally. Different carriers perform better depending on the destination, parcel type and delivery speed. Having access to multiple options gives you the flexibility to choose the best route for each order.
It also helps you stay competitive on pricing and avoid disruptions if one service runs into delays.
Customs, Duties & US Tax Basics
For UK eCommerce brands, getting your head around US tax rules and cross-border duties is one of the most off-putting aspects of getting started with selling to the US.
It’s not complicated once you understand it, but if you bury your head in the sand or get paperwork wrong, it can frustrate your customers pretty quickly.
Customs
Every order you send to the USA will go through US customs. If any paperwork is missing or incorrect, shipments can be delayed, held, or even returned.
So what can you actually do to get this right?
- Use clear product descriptions: Avoid vague terms like “accessories” or “goods”.
- Make sure values are accurate: Under-declaring might look tempting, but it can lead to fines, delays, or rejected shipments.
- Use the correct commodity (HS) codes: These tell customs what your product is and how it should be treated. Getting this wrong can cause issues at the border.
- Work with carriers or a 3PL that handles this regularly: Most experienced shipping partners will guide you on documentation and flag issues before your parcels leave UK soil.
- Keep things consistent: Using the same formats and processes for every shipment reduces errors as you scale.
Duties & Taxes
One of the biggest decisions when selling to the USA is how you handle import duties and taxes. The US tax system works differently from the UK. Instead of a single VAT rate, sales tax is handled on a state-by-state basis, and your obligations can change depending on how and where you’re selling.
If you’re selling on US marketplaces like Amazon or reaching a certain level of sales in specific states, you may create an economic nexus. This can mean you need to register and collect sales tax from US shoppers, even without a physical presence in the country.
There are two common ways to deal with these taxes, and it’s up to you which approach you take:
- DDU (Delivered Duties Unpaid) – the customer pays duties and taxes when the parcel arrives
- DDP (Delivered Duties Paid) – you cover the costs upfront and include them in the total price
With DDU, customers may be contacted by the courier and asked to pay before delivery. If they’re not expecting it, it can lead to delays, refused parcels, or support headaches.
With DDP, everything is handled upfront. The customer pays once at checkout, and the order arrives without extra charges.
Product Compliance
Some products need extra checks before they can be sold and shipped into the USA, and this is where a few brands get caught out.
In the US, different regulators oversee different product types. If you’re selling cosmetics, skincare, food, or supplements, you’re likely dealing with the FDA. General consumer goods fall under the CPSC, while electronics and anything with wireless features are usually covered by the FCC. Each of these has its own rules around labelling, ingredients, safety standards, and documentation.
And no, you can’t get around this by adding a label like “Made in the UK”. Where a product is made doesn’t override US import rules. It still needs to meet US standards to be allowed into the country.
So what does that mean in practice?
- You may need specific labels or warnings on your products
- Ingredients or materials might need to meet US-approved standards
- Some products require registration, testing, or certification before they can be sold
This is all manageable with a bit of upfront work. Checking the relevant guidelines for your product category, confirming details with your manufacturer, and working with experienced fulfilment or shipping partners can help you avoid issues before your products even leave the warehouse.
How to Make Selling to the USA from the UK Scalable
Inventory Management
Inventory management and calculating stock turnover become more important once you’re selling overseas. If you run out of stock, customers are waiting longer for orders that already take more time to arrive. On the flip side, overstocking ties up cash and warehouse space.
Having clear, real-time visibility over your inventory helps you stay ahead of demand, so that you can plan reorders properly and avoid unnecessary delays.
Order Processing
As order volumes grow, fulfilment speed and accuracy need to keep up. A few manual steps might work when you’re processing a handful of orders a day. Once that turns into dozens or hundreds, it becomes harder to keep everything consistent.
Order fulfilment mistakes lead to incorrect shipments, delays, and more time spent fixing problems than moving forward. That’s usually the point where manual processes stop being workable.
Shipping optimisation
Rather than relying on a single courier service, it’s better to build a flexible setup that lets you choose between carriers and delivery speeds based on each order. That might mean using one option for standard delivery and another for faster shipments, or switching based on parcel size and destination.
If you’re unsure which routes make the most sense, it’s worth comparing how different carriers perform across international deliveries – for example, Evri vs DHL, as this can vary more than you’d expect.
Over time, reviewing your shipping data helps you spot patterns, reduce unnecessary costs, and keep delivery performance consistent as you scale.
Technology
Managing orders, inventory, and shipping across separate platforms might work early on, but it doesn’t take long before it starts slowing everything down. More manual input means more room for errors, delays, and time spent fixing issues instead of growing the business.
An automated fulfilment setup removes a lot of that friction. Orders can move straight from your eCommerce platform into your fulfilment system without manual handling. Stock levels update in real time, picking and packing are triggered automatically, and tracking is shared with customers as soon as their order is on the move.
This becomes even more important when you’re selling across multiple channels. Whether orders are coming through Shopify, Amazon, or TikTok, having everything linked keeps things consistent and easier to manage.
It also means you’re not jumping between systems trying to work out what’s been shipped, what’s in stock, and what still needs attention.
Why eCommerce Brands Use a 3PL for Fulfilment in the U.S
Instead of building out your own international setup, you can plug into an existing global fulfilment network. That means your products can be stored closer to your customers, or shipped directly from the UK using reliable international routes.
For many brands, starting with UK-based fulfilment is the simplest option. Orders can be picked, packed, and shipped overseas with delivery in around 1-2 weeks, without needing to commit to stock in another country. As demand grows, having access to global fulfilment centres gives you the option to reduce delivery times further, without rebuilding your entire operation.
Behind the scenes, it also brings consistency. Orders are processed quickly, stock is tracked in real time, and accuracy stays high even as volumes increase. That’s what keeps customer experience steady as you scale, rather than becoming harder to manage.
And because a 3PL ships at volume across multiple carriers, you benefit from better courier rates than you’d usually get on your own. Over time, that can make a noticeable difference to your margins.
