Brand Registry, MAP & resellers
When a wholesale customer starts listing your product on Amazon, you have a commercial problem rather than a legal one. They bought genuine goods and they are entitled to resell them. Amazon will not remove them, your trademark does not reach them, and your only real lever is whether they get another order.
The good news is that this is predictable, which means it is preventable. Almost every case traces back to one of three things: you never told them Amazon was off limits, your wholesale price left them more margin on your ASIN than in their own store, or the stock reached them through a route you did not design. All three are fixable before the first pallet ships.
Why it happens
Put yourself in the buyer's position. They bought a case of twelve at 18 dollars a unit for a product that sells at 39 dollars on Amazon. In their shop they sell four a month at 36 dollars. On Amazon, the same units move in days at 33 dollars, and after referral and fulfilment fees they still clear more per unit per week than the shelf does.
Nothing about that is malicious. It is arithmetic, and you handed them the arithmetic when you set the wholesale price without thinking about what the marketplace offers as an alternative outlet.
The second common cause is silence. A brand sends a price list and ships an order without ever saying which channels are approved. The buyer assumes anything goes, because from their side it does. Naming the channels in one sentence prevents most of this, and the clause belongs in the agreement, as described in the Amazon reseller agreement.
The third is downstream leakage — the account did not list it, their customer did, or a liquidator bought their clearance. That one is invisible unless you design for it.
Decide whether you actually mind
Not every case is bad, and treating them all the same costs you accounts you should keep.
A distributor listing on your ASIN at your price, with fast fulfilment, while you are out of stock. This is arguably helpful. Your listing keeps selling, rank holds, and the customer gets the product. Some brands formalise this as a backup arrangement.
A retailer listing a small quantity at full price. Low harm. They are competing for the Buy Box occasionally and not moving the price.
Anyone listing below your floor. This is the damaging case, because the Buy Box price is what every other account and every customer sees. One discounter repricing your listing repositions the whole brand.
A seller you cannot identify at all. The one to investigate first, because it means you have lost track of where your product goes.
Deciding which of these you mind, and writing that down, turns an emotional reaction into a rule you can apply consistently. The monitoring routine that catches them early is in MAP policy monitoring and enforcement.
Price the wholesale channel so the marketplace is the worse option
This is the structural fix and it beats every enforcement mechanism.
Work backwards from the outcomes you want. You want a physical retailer to make a healthy margin selling on a shelf, and you want the same unit to be unattractive as an Amazon offer below your floor. Those two goals are compatible if you think about the marketplace maths when you set the price.
An Amazon seller pays a referral fee on the sale price, a fulfilment fee if they use Amazon logistics, and carries returns. Take the made-up numbers above: at a 33 dollar selling price, referral and fulfilment might take around 10 dollars, leaving 23 dollars against an 18 dollar cost. That is a thin five dollars, and it is thin enough that a serious retailer would rather sell it in the shop. At a 15 dollar wholesale price, the same listing leaves eight dollars, and now the marketplace looks good.
So the wholesale price is not just a margin decision, it is a channel-design decision. Going too deep on wholesale to win a big account funds that account's ability to compete with you on your own listing. The wider tension between the two channels is worked through in Amazon private label vs wholesale and wholesale for Amazon brands.
A second structural lever: sell a different configuration into wholesale. A case-pack-only version, a retail two-pack, a variant with different packaging. If the units the retailer holds do not match your Amazon ASIN, they cannot list against you without creating a new listing, which most will not bother to do.
The conversation when it happens
Keep it commercial and unemotional, because the account probably does not think they did anything wrong.
Contact them directly rather than filing anything. Name the ASIN, the price, and the term in your policy. Ask them to adjust or remove the offer within a defined window. Most do, and most did not realise it mattered.
If they push back, ask what they are trying to solve. Often it is slow-moving stock, and the better answer for both of you is a one-off buy-back or a swap for a different line rather than a clearance run on your own listing. A brand willing to take back dead stock occasionally buys itself a lot of channel discipline.
If they do not correct it, apply the ladder you published: notice, hold the next order, remove from the authorised list. Consistency is what makes this work across your other accounts, and the framework sits in an authorised reseller programme.
The one thing not to do is report them to Amazon for something they did not do. Filing an infringement complaint against a legitimate reseller wastes the report and damages your standing for the reports that matter, which is covered in how to remove unauthorized sellers.
Making the leak traceable
You cannot enforce what you cannot trace, and most brands discover this the first time it happens.
Put a lot or batch code on every case and record which code went to which account. Buy a unit from the seller in question, read the code, and you have your answer in minutes rather than months.
Require distributors to report which accounts received product, quarterly. Not as surveillance, as a normal condition of a deeper price tier.
Write an end-customer restriction into the agreement, so that accounts other than distributors may not sell on to other resellers without approval. Most leakage happens two steps downstream from the account you signed.
And if the problem is chronic rather than occasional, serialising units through Transparency turns the whole thing from an investigation into a gate, because units without valid codes cannot enter your ASINs through fulfilment.
Selecting accounts that will not do this
The cleanest prevention is choosing accounts whose business is not compatible with marketplace reselling in the first place.
A regional chain with physical stores, a specialty retailer with a curated assortment, a distributor serving independent shops — none of these have an obvious reason to list on Amazon. An online-only reseller whose entire operation is marketplace arbitrage has every reason to, and no amount of policy language changes what their business is.
That means the account selection conversation matters more than the contract. Ask on the application which channels they sell in and what share of their revenue comes from marketplaces. The answer tells you what will happen a month after the first shipment.
Finding the accounts whose business fits yours is the hard part when your entire commercial experience is a marketplace. Paste your listing into WholesalePilot and the preview shows which distributors and retailers plausibly stock products like yours, which is a better starting list than whoever happens to email you.
Questions Amazon brands ask about wholesale accounts reselling
Can I legally stop a customer reselling what they bought? You can decline to sell to them again, and a channel clause makes that clean. You generally cannot stop the resale of goods they already own.
Will Amazon remove them if I say they are unauthorised? No. Genuine goods may be resold.
Should I refuse all wholesale to avoid this? No. The channel is usually worth more than the occasional listing incident, and the incidents are manageable with pricing and selection.
What if my distributor's customer is the one listing? That is why the sub-selling clause and the reporting requirement exist. Without them you have no route to the party involved.
Is a different case pack for wholesale worth the production complexity? For a brand whose Amazon listing is its main asset, usually yes.
Do I need a separate price list for online accounts? Many brands run one, with a higher price and tighter terms for marketplace sellers. It is a reasonable way to keep both channels.
