How to protect your brand on Amazon from unauthorized sellers

As a team of Amazon sales & strategy consultants, we often talk with a lot of brand owners who are not yet actively selling on Amazon. Following our initial marketplace analysis, it might come as a surprise for these owners when we find that their products are actually being sold on Amazon, by other sellers. It then begs the question, “How are other people allowed to sell my product on Amazon without my permission?

The fact is that Amazon is a marketplace where anyone can sell goods that they legally acquired. Amazon’s strategy is to offer the largest assortment of products, with the most convenient buying experience at competitive prices. (Notice I don’t say at the cheapest price - Amazon has actively moved away from being “cheap” to “convenient”.)



Having many sellers hawking the same product in the same marketplace, has the typical result of driving prices down. This pro-buyer policy is accomplished through the “Buy Box” algorithm, which is the way Amazon’s system chooses which seller gets the sale in cases where multiple sellers are offering the same product.

How to protect your brand on Amazon from unauthorized sellers


As much as the price-reducing mechanism of having multiple sellers per product listing is helpful to Amazon and to customers, many brands are less fond of the concept. And there are various reasons: from reduced prices to brand perception and even affecting B2B relationships. While many sellers accept the rules of the game and  strive to win the Buy Box algorithm, for others, the concept of the Buy Box creates a major sticking point:

  • It generally drives down the price of their products. Having multiple sellers of a product often results in them competing on price. ‘Repricing’ software is often used by these sellers to automate the process of reducing prices of items in order to win the Buy Box and  get the sale.

  • Reduced prices may affect customer perception of the brand. If your brand has a strategic pricing model, it can be frustrating to have this undermined in such a significant market.

  • Reduced prices affect relationships with other vendors. Brands who sell to retail stores or distributors might find these relationships are affected when they see a low price on Amazon. You might have a MAP (Minimum Advertised Price) policy in place with your other vendors, which might be flagrantly ignored on Amazon by an anonymous seller.

  • Product pages that are off-brand. Anyone can create a new listing for your product if they have products in stock in new condition and an Amazon Seller Account. They may not have the correct product information or might be using a poor quality product photo. Since there is little incentive to follow brand guidelines for the listing, the brand experience may take a toll. This is frustrating for brands who have worked hard to develop consistency across their sales channels, only to have it undermined by rogue sellers.

The policing of your brand on Amazon comes down squarely on the shoulders of the brand. Some brands may even decide Amazon isn’t for them after all.

This was the case of Birkenstock, a company with a history of about 240 years, that has decided, earlier this month, it was time to move away from Amazon. Their decision is aimed to achieve better control of the brand, both in terms of authenticity and price, and  does come at a time when their products appear to be experiencing a revival.

But how about brands that are doing so well on Amazon, that they don’t want to leave it? They want to start or continue selling in this marketplace, although they might have to overcome the challenge of unauthorized sellers.



7 ways to protectyour brand on AMAZON - bobsled marketing consultants

1. Understand that Amazon will not help you take down unauthorized sellers.

Amazon wants to have multiple sellers of each product, because it often helps to keep prices competitive, hence making the products (and the overall marketplace) all the more appealing to buyers. Asking Amazon to help police your brand will fall on deaf ears, even if you have protective assets like a patent or trademark. Amazon does not view unauthorized sellers (i.e. anyone but you and your authorized distributors) as policy violators. Amazon is a catalog business which is actually designed for more than 1 seller to be on an individual listing. Only counterfeit items are against Amazon's policy.


2. Apply for the Amazon Brand Registry.

Brand Registry is an Amazon program fairly easy to enroll in if you’re the manufacturer or an OEM with a branded product. Your enrollment ensures that other sellers cannot easily make changes to your product detail page. It is an important way of ensuring that your product pages are represented correctly, but  doesn’t prevent other sellers from listing your product. It also certifies you as the brand owner  which gives you several important tools such as:

  • Allows you to not have to use UPCs to list your products
  • Your “content contribution” outweighs any other Sellers. The copy, keywords and other product listing content you submit will override any content that other Sellers try to submit.

Please take note, this presupposes the brand is registered properly, and that every product has been correctly enrolled - including Manufacturer part Number and UPC codes. If you would like an Amazon consultant to assist with your Brand Registry, please contact us.



Maintain a public website for your brand for which you can prove ownership - this is actually a requirement for applying to the Amazon Brand Registry. You should also have  your brand name printed on the packaging and the actual product. This is another requirement of the Brand Registry process, but will also help in identifying counterfeit items (see below).



Execute iron-clad agreement with distributors, resellers or retailers who may sell your product, explicitly preventing them from selling your brand on Amazon themselves, or to adhere to your MAP policy if preferred. If you find that wholesale distributors are ignoring the exclusivity or MAP clause, you can then choose to take further action which could include raising their wholesale price so that it’s financially untenable for them to continue, thereby undercutting you on Amazon.

Further protection can also be found in ncluding serialization on products. This allows you to find out which distributor might be doing this, so you can trace back to the problem distributor. Enforcing an exclusivity contract is just as important as setting it up. You’ll want to be tracking who is selling your products on a regular basis, and nip any untoward behavior in the bud.



One way we do this for Bobsled Marketing’s clients, is to proactively monitor product pages and accounts to identify when products have unauthorized Amazon sellers. When we identify such products, we have a two-step process to handle the issue:

  1. Send a 'cease and desist' style message through the Amazon system directly to the other seller. This eliminates a good percentage of unauthorized sellers.  

  2. If we believe it is a counterfeit item, we place a 'test buy' to validate. After verifying that the product is not authentic, we file a complaint with Amazon and try to have the seller’s offer taken down. You will not get any compensation from Amazon for doing this.



When you sign Fulfilled By Amazon (FBA) (read more about this program, here) , there is an option available to not apply Amazon barcode labels (stickers) to your inventory when it’s shipped in. However convenient it might seem, do not use this option. This means your product can be mixed in with potentially counterfeit items.



We have written plenty more content about Seller Central vs Vendor Central (basically the difference between selling on Amazon directly to their customers, or selling to Amazon on a wholesale basis). One other benefit of being a Vendor on Amazon is that you will become the defacto brand owner on Amazon. It will be extremely difficult for other sellers to make changes to your product detail page, such as changing the product description and product images, adding new variations, and other unwelcome changes.  


During our experience as Amazon consultants, we found the following frequently asked questions to be important considerations for sellers looking to protect their brand against unauthorized sellers. Kiri Masters, our CEO, provides the answers.



A: I advise against setting up a US entity simply for the purposes of policing your brand, as it won’t necessarily be noticeably effective. Some of these unauthorized sellers won’t be US companies either, so it won’t necessarily be easy to enforce legal action. By setting up a US entity you’ll also need to start dealing with all the paperwork, legal and tax affairs required of US companies.


Q: Will a trademark or patent help?

A: Trademarking would be prudent and give you more grounds for legal action in a ‘worst case’ scenario. But it is difficult to actually obtain the identity of many sellers on Amazon, so you may not even get to that point without considerable expense.


Q: Is it possible to Block other sellers on my product pages?

A: No, and this goes against the whole value of Amazon’s marketplace. You can put the above protections in place, but you’ll need to also supplement that with ongoing monitoring of your product pages and react to any new, unauthorized sellers.


Q: I have a MAP policy in place- shouldn't that protect me?

A: Amazon does not care about MAP and they will do nothing to enforce it. Use serialization to determine which, if any, of your distributors are violating MAP.  Also remember that from a legal standpoint, MAP is a concept that is only really used in the USA, outside the USA such practices are considered price fixing.
