U.S. Warehouse for Foreign Sellers: What to Check First

The short answer

• Storing inventory in the United States moves customs from every order to each inbound shipment: goods are declared once, in bulk, when they arrive.
• Duties depend on classification, origin and value of the goods, not on where they are stored.
• Since South Dakota v. Wayfair, states can require remote sellers to collect sales tax once they pass an economic threshold. Holding inventory in a state may create obligations there as well: check each state.
• A U.S. company is not always required by the warehouse, but many warehouses ask for a company to sign the contract: ask before you decide.
• The real comparison is landed cost per order, including storage, handling, freight, duties and returns.

Sellers based abroad reach a point where every order shipped from overseas hurts: slow delivery, unpredictable costs, customers asking about returns. Holding inventory in the United States solves part of that. It also creates obligations that many sellers do not expect.

This guide lists what changes, and what to ask a warehouse before you sign.

What changes when inventory is in the United States

Customs moves to the inbound shipment. Instead of declaring each parcel, you import goods in bulk and declare them once when they arrive. Our guide to customs clearance explains the steps. CBP notes that shipments valued under $2,500 can in most cases be cleared as informal entries, while larger commercial imports generally need a formal entry and a bond.

Delivery becomes domestic. Orders ship from a U.S. location, which usually shortens delivery times and simplifies returns. It also means you pay storage and handling before you sell.

Sales tax may follow the inventory. Since South Dakota v. Wayfair, states can require sellers without a physical presence to collect sales tax once they pass an economic threshold. Holding inventory in a state may create obligations there in addition to the threshold rules: check each state where you store goods. See our guide to sales tax for online sellers. [Probabile]

What does not change

• Duties: they depend on classification, origin and value of the goods.
• Your U.S. company’s yearly filings, including Form 5472 for a foreign-owned single-member LLC with reportable transactions.
• The need for accurate invoices and documents on each inbound shipment.

Do you need a U.S. company?

Some warehouses and fulfillment providers only work with U.S. companies, and others accept foreign companies with extra requirements. There is no single rule, so ask each provider. If a company is needed, see importing into the USA and the best state to form an LLC.

Questions to ask a warehouse or 3PL

1. Who can sign the contract? A U.S. company only, or also a foreign company?
2. What are all the fees? Receiving, storage, picking, packing, materials, returns and long-term storage.
3. What are the minimums? Monthly minimums, minimum inventory, contract length and how to exit.
4. What insurance covers the goods? What is covered, what is excluded and who pays for damage or loss.
5. How do they integrate with your store or marketplace? Which platforms and how orders and stock sync.
6. How do they handle returns? Inspection, restocking, disposal and the fees for each.
7. Where is the warehouse? The state matters for shipping times and for the tax questions above.
8. What are the reports? Stock levels, order errors and shipping performance.

Compare with landed cost, not with a shipping rate

Compare per-order cost from overseas with per-order cost from a U.S. warehouse. Include storage, handling, inbound freight, duties, broker fees and returns. Our guide on pricing with landed cost shows how.

Start small

A first inbound shipment of your best-selling products tells you more than a projection: it shows the real receiving time, fees and error rate. Increase volume after you see the numbers.

Frequently asked questions

Do I need a U.S. LLC to use a U.S. warehouse?

It depends on the provider. Some require a U.S. company to sign the contract, others accept foreign companies. Ask before you decide.

Does storing inventory in the U.S. create sales tax obligations?

It can. Check the rules of each state where you store goods, in addition to the economic thresholds of the states where you sell.

Do I pay duties when goods enter a U.S. warehouse?

Duties are paid on import, based on classification, origin and value, before goods are stored.

Is a U.S. warehouse cheaper than shipping from abroad?

It depends on volumes, product size and fees. Compare the landed cost per order.
