Selling Online in the USA: What International Stores Need
In this article9 sections
To sell online in the USA successfully as an international store, you need to get five things right: sales tax rules that differ by state, import duties and customs paperwork, fast and predictable delivery, the payment methods Americans use, and a store that meets local expectations on accessibility, privacy and customer service. None of these is impossible, but each one is different from selling at home. Stores that plan for them before launch avoid the costly surprises that catch many cross-border sellers.
Key takeaways
- There is no national sales tax; each state sets its own rules, and you may owe tax in a state once your sales there pass its threshold.
- Import duty rules changed in recent years, so check current customs guidance before you set prices.
- American shoppers expect clear delivery dates, easy returns and prices shown in US dollars.
- Offer cards, digital wallets and buy now, pay later options at checkout.
- Build accessibility and state privacy rules into the store from the start.
Is the US market right for your store?
The size of the US market attracts many sellers, but size alone is not a plan. Before investing, look at whether there is demand for your specific products and whether you can compete on delivery and price.
- Check demand. Look at search interest in the US for your product terms, and at whether American customers already visit or buy from your store.
- Study competitors. Who already sells similar products to Americans, at what price, with what delivery promise?
- Do the maths on landed cost. Add shipping, duties, taxes, payment fees and returns to your product cost. Can you still sell at a competitive price?
- Decide where to start. Some sellers begin by shipping from home, then move stock to a US warehouse once demand is proven.
It also helps to think in regions. Delivery times, climate and seasonal buying patterns differ widely between, for example, the Northeast, the South and the West Coast. A product that sells well in Florida in January may not sell at all in Minnesota.
Sales tax: one country, many rules
Sales tax is the area that surprises international sellers most. Unlike VAT or GST in many countries, there is no single national sales tax in the United States. Each state sets its own rules, and many cities and counties add their own rates.
How economic nexus works
Since a 2018 Supreme Court decision, South Dakota v. Wayfair, states can require remote sellers to collect sales tax once their sales into that state pass a threshold, even if the seller has no office or staff there. This is called economic nexus. The thresholds and rules vary by state, and they apply to foreign sellers too.
What this means in practice
- Track your sales by state from the first day.
- Register to collect tax in each state where you pass the threshold.
- Calculate tax at checkout based on the delivery address, not a single flat rate.
- File returns and pay the tax collected on the schedule each state sets.
Most stores use a sales tax service that plugs into the platform, calculates the right rate for each address and helps with filing. Marketplaces often collect and pay sales tax on your behalf, which is one reason some sellers start there. Take advice from a US tax professional before you launch; this is an area where rules change and details matter.
Show prices the American way
American shoppers expect prices without tax, with sales tax added at checkout once the address is known. Showing tax-inclusive prices, as is normal in many other countries, can confuse them.
Customs, duties and shipping into the US
If you ship from outside the country, every parcel passes through US customs. Duty rules for low-value parcels have changed significantly in recent years, so check the current position with US Customs and Border Protection or your carrier before setting prices.
Decide who pays duties
You have two broad options:
| Approach | How it works | Customer experience |
|---|---|---|
| Delivered duty paid (DDP) | You calculate and pay duties and charge the customer at checkout | No surprise fees at the door |
| Delivered duty unpaid (DDU) | The customer pays duties and fees on delivery | Unexpected charges, refused parcels and complaints |
For consumer orders, charging duties at checkout is almost always the better experience. Many carriers and cross-border services offer tools to calculate the amount in advance.
Get the paperwork right
- Describe every product accurately on the customs declaration.
- Use the correct tariff classification code for each product.
- Declare the country of origin and the true value.
- Check whether any products are restricted or need extra approval, such as some cosmetics, food and electronics.
Delivery expectations
Large online retailers have taught American shoppers to expect fast, tracked and often free delivery. You may not match the fastest options from abroad, but you can be clear and reliable. Show an estimated delivery date at checkout, give tracking for every order, and explain any delays honestly. For faster delivery, consider a US fulfilment partner once your volumes justify it.
Payments American shoppers expect
Cards remain central, but the US checkout has become more varied. Make sure you offer:
- Major credit and debit cards, with clear security branding.
- Digital wallets, such as Apple Pay, Google Pay and PayPal, which make mobile checkout much faster.
- Buy now, pay later options, which are popular for higher-priced items.
Charge in US dollars. A price in a foreign currency, followed by a currency conversion fee from the customer's bank, is a common reason for abandoned checkouts. Choose a payment provider that can settle US dollar payments to your account at a fair exchange rate. Our guide to reducing cart abandonment explains why payment choice matters so much at the last step.
Fraud and chargebacks
US customers can dispute card payments through their bank, and chargebacks are common in cross-border trade. Use your provider's fraud tools, keep proof of delivery and write a clear description of each product, so you can respond to disputes with evidence.
Localise the store for American customers
Translation is not the issue for most English-language stores, but localisation still matters. Small differences signal that a store was not built with American shoppers in mind.
- Spelling and terms: "color" not "colour", "cart" not "basket", "zip code" not "postcode", "pants" rather than "trousers".
- Units: inches, feet, pounds and ounces, with metric as a secondary option if useful.
- Sizes: US clothing and shoe sizes, with a conversion chart.
- Dates and phone numbers: month before day, and a US-style phone number if you have one.
- Address forms: state dropdown, zip code field and address validation.
- Holidays and seasons: plan around Thanksgiving, Black Friday, Cyber Monday and the end-of-year holidays.
Customer service hours matter too. If your team is in another time zone, be clear about when you answer, offer email or chat that customers can use any time, and aim to reply within one business day.
Legal basics: accessibility, privacy and consumer rules
This section is an overview, not legal advice. Speak to a US lawyer about your specific situation.
Accessibility
Many US businesses have faced lawsuits claiming their websites are not accessible to people with disabilities. Building the store to the WCAG guidelines from the start is the practical way to reduce that risk, and it makes the store easier for everyone to use.
Privacy
There is no single national privacy law for consumer data, but several states, starting with California, have their own. They give consumers rights to know what data is collected, to delete it and to opt out of its sale or sharing. Write a clear privacy policy, collect only what you need and give customers a simple way to exercise their rights.
Consumer protection
The Federal Trade Commission's mail, internet or telephone order rule, published as 16 CFR Part 435, requires sellers to ship within the time they state, and to give customers a choice when there is a delay. Be accurate about delivery promises, honest in reviews and endorsements, and clear about subscription terms if you sell recurring products.
Marketing to American shoppers
Getting found is the next challenge. American shoppers compare widely, read reviews closely and respond to clear value. A few approaches tend to work well for international stores entering the market.
Search and content
Make sure your pages use the words Americans search for, which may differ from the terms used in your home market. "Sneakers" and "trainers" describe the same shoe, but only one will reach US shoppers. If you run separate storefronts for different countries, use hreflang tags so search engines show the right version to each audience. Our e-commerce SEO guide explains the foundations.
Reviews and social proof
Reviews from American customers carry particular weight with other Americans. Ask early US buyers for honest reviews, and show the reviewer's location where your platform allows. Follow the FTC's rules on endorsements: never pay for positive reviews or hide negative ones.
Paid advertising
Search and social ads can bring US traffic quickly, but costs per click in competitive categories can be high. Start with a small budget on your best-selling products, track profit after shipping and duties, and expand only what earns its keep.
How to sell online in the USA: a launch checklist
| Area | Check |
|---|---|
| Market | Demand, competitors and landed cost reviewed |
| Sales tax | Sales tracked by state; registration plan; tax calculated by address |
| Customs | Tariff codes, origin and duty approach decided |
| Delivery | Carriers chosen, delivery dates shown, tracking on every order |
| Payments | USD pricing; cards, wallets and buy now, pay later |
| Localisation | US spelling, units, sizes and address forms |
| Returns | A US return address or a clear return process |
| Accessibility | Store tested against WCAG |
| Privacy | Policy updated; data rights process in place |
| Support | Hours, channels and response times published |
Returns deserve special thought. Shipping a return back across an ocean is slow and expensive. Many international sellers use a US returns address or a returns service, or offer refunds without return for low-value items. Our guide to writing an ecommerce returns policy covers the options.
Frequently asked questions
Do I need a US company to sell online in the USA?
Not always. Many foreign businesses sell to American customers directly. A US entity can make banking, payments, taxes and fulfilment easier as you grow, so take advice on whether and when one makes sense for you.
Do I have to collect sales tax as a foreign seller?
Possibly. Once your sales into a state pass its economic nexus threshold, that state can require you to register and collect tax, wherever you are based. Track sales by state and take professional advice early.
Should I start on a marketplace or my own store?
A marketplace gives quick access to US shoppers and often handles sales tax, but takes fees and controls the customer relationship. Your own store builds your brand and data. Many sellers use both.
How can I offer fast delivery from abroad?
Use an express international service with duties paid at checkout to start. As volumes grow, move your best sellers into a US fulfilment centre so you can offer domestic delivery times.
