A brand sees an unauthorized seller undercutting its price on a marketplace and fires off a counterfeit report. The report gets rejected. The seller keeps selling. The brand files again, louder. It gets rejected again. Months go by before someone explains the truth: the seller was never selling fakes. They were selling genuine product bought through unofficial channels, and that is a completely different fight with completely different rules.
Gray market and counterfeit look identical to a brand manager scanning a marketplace: unauthorized seller, below-MAP price, unfamiliar storefront. But one involves fake product and the other involves real product sold the wrong way. Filing the wrong claim wastes months, burns relationships with platforms, and can even create legal exposure. Telling them apart early is one of the highest value skills in brand enforcement.
Gray market sellers deal in genuine product. They buy it legitimately, through distributors, overstock liquidators, international wholesalers, or retail arbitrage, and resell it where they are not authorized to. The item in the box is the real thing, made by the brand, with the brand's logo because the brand put it there.
Common sources include overstock from a retailer that ordered too much, international product diverted from a lower price region, and bulk purchases from a distributor that quietly sells past its authorized territory. None of this is counterfeiting. It is a distribution problem, and it is usually someone in the brand's own supply chain who let it happen.
Counterfeit claims work because platforms do not want fake goods. A clean test purchase showing a fake product gets listings removed fast, because every marketplace has a hard policy against counterfeits and the legal incentives to enforce it. Gray market claims have no such engine. Selling a genuine product you own is generally legal under the first sale doctrine, which means the platform has no policy violation to act on and no legal pressure to do so.
This is why gray market reports filed as counterfeit complaints get rejected. The platform investigates, finds genuine product, and closes the case. Worse, repeated false counterfeit claims can get the brand's own reporting account flagged, making future real counterfeit reports slower to process. Every gray market seller you report as a counterfeiter teaches the platform to trust your reports less.
Test buy from the suspect seller. This is the single most reliable step, and it works for both cases. If what arrives is fake, wrong materials, wrong packaging, misspellings, missing serials, you have a counterfeit case and your standard enforcement playbook applies. If what arrives is genuine, you have a gray market case and you need a different playbook entirely.
Look at the listing itself. Counterfeit listings usually show stolen or slightly altered product photos, odd pricing far below cost, and new seller accounts with thin history. Gray market listings often use the brand's own catalog photos, price just below MAP, and come from established sellers with long histories and real feedback. An old, high feedback seller moving volume at a slight discount is almost never a counterfeiter; counterfeiters cannot survive that long in the open.
Start upstream, not at the marketplace. Gray market product came from somewhere in your distribution chain, and the leak is worth more to fix than any single listing. Check lot codes, batch numbers, and regional packaging markers on the test buy to trace which distributor, region, or retailer the product leaked from. One conversation with a distributor moves more gray market volume than a hundred marketplace reports.
Use your authorized distribution agreements. Minimum advertised price policies, authorized seller programs, and territory restrictions are the real enforcement tools here. Amazon's Brand Registry lets brands gate listings so only authorized sellers can list against their ASINs, which cuts off gray market sellers at the marketplace level without any infringement claim. That gate is the single most effective gray market control on Amazon.
For persistent gray market sellers, a carefully drafted cease and desist from counsel can work, particularly where the seller is using your brand assets or violating MAP terms they agreed to. This is legal territory, not a reporting portal, so run it through counsel and keep the claims accurate. Threatening a counterfeit lawsuit against a genuine-product seller is exactly how brands end up as defendants.
In practice the two problems mix. A gray market seller's cheap genuine listing attracts price sensitive buyers, and counterfeiters piggyback on the same ASIN with fakes priced a dollar lower. Triage ruthlessly: kill the counterfeits first with clean test buy evidence, because that engine works fast, then take the gray market supply chain problem to your distributors. Fixing both with the counterfeit playbook alone is how brands burn a year and change nothing.
