Defending Counterfeit and Inauthentic Item Claims

What triggers a counterfeit or inauthentic claim

Test buys are the most common source for brand-filed counterfeit claims. A brand or its enforcement agency purchases a unit, inspects it for authenticity markers such as packaging, holograms, serial numbers, or manufacturing details, and files a notice if anything does not match. Sellers holding entirely genuine inventory can still fail this check if the goods were manufactured for a different market, packaged for a different retailer, or altered somewhere in the resale chain.

Buyer-reported inauthentic complaints arise differently. A customer receives an item, believes it is not genuine, and returns it with that reason selected, or leaves a review saying so. Amazon aggregates these reports, and a cluster of them on the same ASIN, even without a formal brand filing, can trigger the same account health consequences as a rights owner notice.

Pricing and sourcing patterns draw scrutiny on their own. A price meaningfully below the brand's typical retail range, a sudden volume of sales on a previously low-selling ASIN, or a listing that mixes new sellers on an established detail page are all signals Amazon and brand enforcement teams watch for independent of any specific complaint.

Sourcing model is the underlying factor in most cases that reach us. Sellers buying through retail arbitrage, liquidation pallets, or unauthorized distributors are frequently selling genuine products, but their supply chain was never designed to produce the kind of documentation Amazon or a brand will accept as proof.

What Amazon requires to resolve the claim

Amazon's stated documentation standard is narrow and specific. It wants invoices or purchase orders from your supplier, issued within a defined lookback period, showing your business's name and address, the supplier's contact information, and quantities consistent with your actual sales volume. A document missing any one of those elements is commonly rejected outright, without an explanation of which element was deficient.

Retail receipts, packing slips without supplier letterhead, and screenshots of supplier communications generally do not satisfy the standard, even when they are completely genuine. Amazon frequently calls the supplier listed on a submitted invoice to confirm the relationship and the transaction, so a document has to be able to survive that verification, not merely look correct on its face.

Where the claim originated from the brand rather than a buyer, an invoice may not be enough even if it satisfies Amazon's format requirements. Some brands maintain closed distribution networks and will treat any unauthorized channel as a violation regardless of the goods' authenticity. In those cases, resolution usually requires either a letter of authorization from the brand or an authorized distributor, or a legal argument under the first sale doctrine that the goods were lawfully acquired and resold without material alteration.

Counterfeit allegations specifically carry consequences that extend past Amazon's own process. A brand that believes it has identified counterfeit sales can pursue civil claims independent of the marketplace dispute, which is why a counterfeit notice should never be answered with the same casual approach a seller might use for a routine listing suppression.

How Stockman & Poropat approaches it, and what non-lawyers cannot do

The first step is classification, not documentation. Inauthentic, counterfeit, and used-sold-as-new claims carry different evidentiary standards and different consequences, and treating them interchangeably is the most common mistake sellers make before contacting us. We identify precisely which claim was made, who made it, and what standard actually applies before deciding what to submit.

Where the supply chain can support it, we assemble documentation in the form Amazon and the brand will actually verify, rather than the form the seller happens to already have on hand. That sometimes means going back to the supplier for a corrected invoice or a signed authorization letter, which a seller working alone often does not know to request or cannot obtain without leverage an attorney can bring to that conversation.

Where the sourcing genuinely cannot be documented to the required standard, we say so directly. Part of this work is telling a seller candidly when a listing cannot be defended and the more productive move is transitioning away from that sourcing channel, rather than continuing to submit documentation that will keep being rejected.

Where the notice came from a rights owner, we engage as counsel rather than let the seller respond directly. Negotiating a retraction attorney to attorney, backed by a first sale or material difference analysis, resolves matters that an appeal alone cannot touch, and it removes the risk of the seller making an unintended admission in a direct email to the brand's enforcement team.

A non-attorney reinstatement service can upload documents to Seller Central, but it cannot negotiate with a rights owner's counsel, cannot evaluate a first sale defense, and cannot assess whether the brand's enforcement conduct itself is actionable. Where a competitor or brand has weaponized false counterfeit allegations to suppress a listing, that assessment can support a claim for damages, and it is a legal determination outside what any non-lawyer service is positioned to make.
