TL;DR: Foreign sellers shipping to the U.S. need their own EIN and U.S. LLC — not a freight forwarder’s or 3PL’s. Using someone else’s EIN creates customs liability, IRS complications, and loss of control over your import records. Setting up a U.S. LLC and EIN costs under $500 and takes 2–4 weeks.
If you are a foreign seller shipping products into the United States, you may have had someone advise you to take one of the following shortcuts:
- “Use your freight forwarder’s EIN.”
- “Have your 3PL act as consignee.”
- “Have your customs broker list their entity on the import paperwork instead of yours.”
It sounds efficient. It is also one of the most expensive mistakes a foreign seller can make. Here is what is actually at stake — and why the right path is simpler and cheaper than most sellers expect.
What “Using Someone Else’s EIN” Actually Means
When goods enter the United States, US Customs and Border Protection requires an Importer of Record (IOR). The IOR is the entity legally responsible for the shipment — responsible for accuracy of the customs declaration, payment of duties and tariffs, compliance with all federal regulations (FDA, CPSC, FCC, EPA, depending on the product), and any fines, penalties, or seizure actions.
The IOR is identified by an EIN — an Employer Identification Number issued by the IRS. When a foreign seller asks a freight forwarder or 3PL to put their EIN on the customs entry, they are asking that company to assume legal responsibility for the shipment.
Most reputable logistics providers will not do this. The ones who will should concern you, because they are either underpricing the risk or not understanding it.
The Sticks: What Goes Wrong Without Your Own EIN
CBP Enforcement
CBP enforces against the entity on the paperwork. If goods are detained, seized, or subject to an anti-dumping investigation, the enforcement action lands on the EIN listed as IOR — not on whoever actually owns the product. No private contract between a seller and a logistics provider overrides federal customs liability.
- Seizure and detention: If your product violates a regulation — mislabeled, missing certifications, subject to a trade restriction — the entity on the paperwork bears the consequences. You lose your inventory with no legal standing to reclaim it.
- Anti-dumping and countervailing duties: Certain product categories from certain countries trigger additional duties. If the IOR did not properly classify and declare, the penalties attach to the IOR.
- Continuous bond liability: The IOR’s customs bond is on the line. One bad shipment can jeopardize the bond a freight forwarder uses for hundreds of other clients. When they discover this, your shipments stop.
And here is something most sellers never consider: if a freight forwarder or broker is willing to share their EIN with you, they are almost certainly sharing it with others. CBP risk-scores by EIN. If any other importer using that same EIN triggers a violation — mislabeled goods, an FDA hold, an anti-dumping flag — the elevated scrutiny applies to every shipment filed under that EIN, including yours. You are inheriting risk from businesses you have never heard of, with no visibility into what they are shipping or how they are classifying it.
Sales and Use Tax Exposure
Using someone else’s EIN does not make your tax obligations disappear. It makes them invisible — until an audit makes them very visible.
If you sell through major marketplaces (Amazon, Walmart, TikTok Shop, etc.), marketplace facilitator laws generally require the platform to collect and remit sales tax on your behalf. In that scenario, the marketplace handles the filings and you may not need your own separate sales tax registrations for those transactions.
If you sell direct-to-consumer through your own website (Shopify, WooCommerce, etc.), the picture changes significantly. Once you have inventory stored in a state — which you do, if you are using a US 3PL — you likely have physical nexus in that state and an obligation to collect and remit sales tax yourself. Operating without proper registration means you are accumulating an undisclosed liability that grows with every transaction. The states have become significantly more aggressive about enforcement post-Wayfair, and voluntary disclosure is far cheaper than an audit assessment plus penalties plus interest.
Either way, none of this goes away because someone else’s EIN is on the import paperwork. The tax obligation follows the economic activity — your products, your sales, your revenue.
The Carrots: What You Unlock With Your Own US Entity
Every Major Marketplace Is Tightening Requirements
The platforms where you want to sell are increasingly requiring US entity documentation. This is not a soft preference — it is a gate you cannot pass through without proper registration.
Amazon requires sellers to submit tax information—U.S. sellers via Form W-9 (needing an EIN or SSN), while foreign sellers can use Form W-8BEN (or W-8BEN-E), which often allows them to claim treaty benefits and reduce or eliminate the standard 30% withholding on U.S.-sourced income in many cases. A U.S. entity with its own EIN can help fully avoid withholding risks entirely while also unlocking smoother compliance and features. Amazon is also now requiring non-resident sellers to designate a Legal Representative in the destination country—a clear signal that anonymous cross-border selling on Amazon is ending.
Walmart Marketplace requires a US Business Tax ID (EIN) and EIN Verification Letter from the Department of Treasury for sellers with US operations. A US entity dramatically simplifies the application and approval process.
TikTok Shop has the strictest requirements of any major marketplace. Business accounts require a US-registered entity with an EIN. Foreign sellers without US entity registration are effectively locked out of TikTok Shop’s US marketplace entirely.
eBay requires tax identification for sellers meeting reporting thresholds. With the $600 Form 1099-K threshold now in effect, virtually every active seller needs proper tax documentation on file.
Shopify does not require an EIN to open a store, but Shopify Payments, Shopify Capital, and most payment processors require US tax documentation for US-based transactions. Without a US entity, you are limited in payment options and locked out of Shopify’s financial tools.
The trend is clear and accelerating: platforms are tightening verification, not loosening it. Registering now means you are set up for every marketplace. Waiting means you may find yourself locked out of a channel exactly when you need it.
Operational Advantages
Beyond marketplace access, having your own US entity removes friction at every point in the supply chain.
- Any reputable 3PL will work with you. You choose your logistics partner based on service quality, not based on who will lend you their EIN.
- Faster customs clearance. Your own bond, your own broker relationship, your own compliance history.
- US banking and payment flexibility. US bank accounts, US payment processors, faster marketplace payouts.
- Credibility with retailers and distributors. A properly structured US entity is table stakes for wholesale partnerships.
- Clean exit or raise. Proper entity structure from the start saves months of legal cleanup if you ever sell or raise capital.
It Is Simpler and Cheaper Than You Think
Here is the part that surprises most foreign sellers: the entire setup is straightforward, affordable, and can be completed in a matter of weeks.
1. Form a US LLC. Wyoming, Nevada, Texas, and Florida are popular choices for foreign-owned entities due to low fees, straightforward processes, and well-established business law. Wyoming in particular has no state income tax, strong privacy protections, and filing fees under $200. You do not need to be physically present — the entire process can be completed online in 3–7 business days.
2. Obtain an EIN from the IRS. The IRS issues EINs to foreign-owned entities at no cost. International applicants can call the IRS directly and receive an EIN the same day, or submit Form SS-4 by mail and receive one in four to six weeks.
3. Open a US bank account. Several banks and fintech platforms now cater specifically to foreign-owned US entities. Mercury, Relay, and banks with international departments can open accounts remotely with your formation documents and EIN, typically within one to five business days.
4. Get a customs bond. Required for importing goods valued over $2,500 (essentially every commercial shipment). Your customs broker arranges this — it is routine, inexpensive, and takes 1–3 business days.
5. Register for sales tax (if applicable). If you sell direct-to-consumer outside of marketplace facilitator channels, register in every state where you have nexus — at minimum, the state where your inventory is stored. Sales tax compliance services automate multi-state registration and filing for a modest monthly fee.
Most foreign sellers can complete the entire process for well under $2,000 — less than the cost of a single pallet of inventory, and a fraction of what a single customs seizure or tax audit would cost.
The Bottom Line
The EIN shortcut is not a shortcut. It is deferred risk with compounding interest for everyone involved.
Every major marketplace is moving toward stricter seller verification. Every reputable logistics provider requires proper documentation. The window for operating in the US market without a US entity is closing faster than most foreign sellers realize.
The registration process takes days, not months. It costs hundreds, not thousands. And it unlocks the full US market — every platform, every 3PL, every payment processor — without the legal and financial exposure of trying to borrow someone else’s identity.
The sellers who build lasting brands in the US market all made this investment early. Not because they wanted to deal with American bureaucracy, but because they understood that a few days of paperwork opens the door to the largest consumer market in the world — on their own terms, with their own name on it.
