Counterfeit sales on online marketplaces can create liability for sellers while also triggering specific compliance duties for marketplace operators. Federal trademark law addresses unauthorized use of registered marks, while the INFORM Consumers Act requires covered marketplaces to identify and monitor certain high-volume third-party sellers. Buyers may also have marketplace, payment, contract, and state consumer-protection remedies.
Seller Liability and Platform Duties Are Different
A seller offering counterfeit branded goods may face claims under federal trademark law when an unauthorized counterfeit or imitation of a registered mark is used in commerce in a manner likely to cause confusion or deception. Federal law also provides special remedies in cases involving counterfeit marks.
Marketplaces have a different set of responsibilities. The INFORM Consumers Act does not simply make a platform the seller of every third-party product. Instead, it imposes identity, verification, disclosure, reporting, and suspension duties involving covered high-volume sellers.
What the INFORM Consumers Act Requires
The law generally applies to online marketplaces where qualifying high-volume third-party sellers offer new or unused consumer products. Covered platforms must collect specified banking, tax, and contact information, verify required information, keep certain information current, and disclose identifying information for sellers who meet additional thresholds.
The FTC provides official INFORM Consumers Act guidance explaining these obligations. Consumers reading consumer news coverage should remember that seller verification reduces anonymity but does not amount to a government guarantee that every product is authentic.
What Buyers Can Do After Receiving a Counterfeit
Start with the seller and marketplace dispute procedures. Preserve the original listing, photographs, order confirmation, payment record, packaging, serial numbers, seller messages, and any authentication information. Marketplace refund windows can be short, so delay can make a practical remedy harder to obtain.
The FTC advises online-marketplace shoppers to review the site’s refund rules, keep records, and use safer payment methods. Credit and debit card disputes may provide another route depending on the transaction and payment method. People comparing retail trend archives should treat platform refund policies as contractual protections that may be broader than minimum legal rights.
| Problem | Possible Route | Useful Evidence |
|---|---|---|
| Fake branded item | Seller or platform claim | Listing and photos |
| Item differs from listing | Payment dispute | Order records |
| Seller identity concern | Marketplace report | Seller profile |
| Repeated deceptive sales | FTC or state complaint | Messages and receipts |
Platform Responsibility Is Not Unlimited
The INFORM Consumers Act gives marketplaces concrete obligations, but it does not create a universal authenticity warranty for every item sold by every third party. Coverage also depends on statutory definitions and seller thresholds.
Enforcement is not theoretical. In September 2025, the FTC announced a $2 million resolution involving alleged INFORM Consumers Act violations by the operator of Temu, including allegations concerning required consumer information and reporting tools. Businesses checking company directory resources should therefore distinguish ordinary seller listings from information a marketplace is legally required to collect or disclose.
What Buyers Often Misunderstand
A low price does not prove an item is counterfeit, while professional photographs do not prove it is genuine. The FTC specifically warns that unusually inexpensive brand-name goods can be a counterfeit warning sign, but authenticity normally depends on the total evidence.
Another mistake is assuming the platform must automatically issue a refund. Marketplace guarantees vary, and legal rights may depend on the seller’s representations, payment method, state law, and the terms accepted during the transaction.
When Legal Help May Be Worth Considering
Legal advice may be appropriate when counterfeit goods involve significant value, repeated commercial sales, business inventory, personal injury, disputed authentication, or a seller refusing a substantial refund. Trademark owners facing repeated unauthorized sales may need specialized intellectual-property counsel.
Consumers can also report suspected deceptive marketplace activity to the FTC and their state attorney general.
Frequently Asked Questions
Does the INFORM Consumers Act ban counterfeit products?
Its purpose includes deterring counterfeit, stolen, and unsafe goods, but its main mechanism is marketplace transparency. It requires covered platforms to collect, verify, and sometimes disclose information about qualifying third-party sellers and provide a reporting mechanism.
Is the marketplace responsible if a seller sends a fake item?
Not automatically. Platform responsibility depends on the applicable statute, the platform’s conduct, contractual promises, and the facts. The seller and the marketplace can have different legal duties.
Can a buyer dispute a counterfeit purchase with a card issuer?
Potentially. Federal and network dispute protections depend on whether a credit or debit card was used and the nature of the problem. Buyers should report the issue promptly and keep documentation supporting the claim.
Preserve Evidence Before the Listing Disappears
The strongest practical response to suspected counterfeiting usually begins with documentation. Save the listing, seller identity, payment information, photographs, and communications before opening disputes with the seller, platform, or payment provider. Marketplace rules can move quickly, while trademark and consumer-protection claims may require a much fuller factual record.
