How B2B Brands Can Protect Themselves from Unauthorized Distributors

Brian Beck and Andy Hoar talk with brand enforcement attorney John Groa about the hidden costs of unauthorized resellers, why most manufacturers do not know who is selling their products on Amazon, and what companies can do to take back control.

Friday 15 Podcast · Guest: John Groa, Partner at KJK

Key takeaways

  • A survey by Enceiba found that nearly 70% of B2B manufacturers have their products sold on Amazon by resellers, and over 70% of those manufacturers do not know who those sellers are.
  • Unauthorized resellers create retail price erosion, channel conflict with authorized distributors, incorrect product information, and in some cases, counterfeit or defective products reaching consumers.
  • Many manufacturers hesitate to enforce brand protection because they do not realize they have intellectual property rights, fear backlash from Amazon or distributors, or are unsure whose budget should cover enforcement.
  • Amazon positions itself as a marketplace and has historically been reluctant to intervene on authorization alone, but becomes more receptive when consumer safety is cited as a concern.
  • Consistent enforcement through monitoring, cease-and-desist letters, and occasional litigation can significantly reduce unauthorized sellers, and word spreads among resellers when a brand takes action.

The scale of the unauthorized seller problem

Brian opened with data from a survey his company Enceiba conducted among several hundred B2B manufacturers. When asked whether resellers were selling their products on Amazon, nearly 70% said yes. When asked whether they knew who those sellers were, over 70% said they did not.

He used Milwaukee Tools as an example of a major brand with significant unauthorized presence on Amazon. One of their top-selling products, generating over a million dollars annually on the platform, had nearly 50 resellers listed, many with names suggesting they were not authorized distributors. Brian noted that this situation is representative of what happens when a brand does not actively manage its marketplace presence.

The real costs of losing control

Brian outlined four categories of harm from unauthorized sellers. First, retail price erosion: unauthorized sellers typically compete by dropping prices, since they have no other differentiation. Second, channel conflict: authorized distributors see lower prices on Amazon and push back during contract negotiations. Third, incorrect product information and sometimes counterfeit goods reaching customers. Fourth, opportunity costs from lost revenue and margin that flows to unauthorized parties instead of the brand.

This is the perhaps most acute example of losing control of your brand online.

Why this matters for buyers too

Andy pushed back initially, asking why a buyer should care if the seller is authorized, since more options seem better. The hosts brought in John Groa, a partner at KJK who runs the firm’s brand enforcement practice, to address this point.

John argued that the consumer protection angle is underappreciated. An unauthorized seller may be selling product that was improperly stored, damaged in shipping, or even counterfeit. For products like power tools, supplements, or batteries, this creates real safety risks. He cited the example of motorcycle helmets sold through Amazon that turned out to be fraudulent, with documented cases of injury.

If I am someone who is invested in my brand, I do not want just any Joe off the street being a quasi ambassador for my brand.

Why manufacturers do not act

The hosts shared a LinkedIn poll asking why B2B companies fail to protect their brands online. The top answer was that companies do not feel they have a way to enforce or police. The second was lack of executive alignment. Almost no one cited lack of intellectual property protection or fear of backlash.

John explained that many manufacturers do not realize they have enforceable rights in their trademarks and copyrights, even if their products are not patented. Others fear getting sideways with Amazon or with their own distribution channels. Budget allocation is another barrier, as enforcement costs often fall awkwardly between legal and e-commerce departments.

What enforcement looks like

John described a typical enforcement program: monitoring marketplace listings, sending cease-and-desist letters, and escalating to litigation only when necessary. He noted that most unauthorized sellers stop when confronted with legal action, and word spreads through reseller communities when a brand is actively enforcing.

If you are not doing anything, I would argue doing something is better than doing nothing. A lot of companies would be surprised at how much progress they can make.

He also emphasized the importance of consistency. Selective enforcement can invite antitrust arguments, so brands should have a documented program and apply it broadly, even if they prioritize the most problematic sellers first.

Amazon’s role and evolving stance

Brian noted that Amazon has historically positioned itself as a marketplace and has been reluctant to intervene on authorization alone. However, when consumer safety is raised as a concern, Amazon becomes more receptive. He mentioned that the Consumer Product Safety Commission has recently moved toward classifying Amazon as a distributor, which could increase Amazon’s legal exposure for products sold through its marketplace.

John confirmed that his firm has a working relationship with Amazon and that manufacturers who frame their concerns around consumer safety tend to make more progress than those who focus only on authorization status.

What B2B manufacturers should take away

The practical message was that brand protection is achievable and does not have to involve expensive litigation. A monitoring and cease-and-desist program can make significant progress. Manufacturers who invest in their brands through advertising and distribution should treat enforcement as part of that investment, not as an afterthought.

Frequently asked questions

Why do so many unauthorized sellers appear on Amazon for B2B brands?

Amazon makes it easy for anyone to list products under an established brand, which attracts opportunistic resellers. These sellers may acquire products through diverted inventory, secondary markets, or promotions like Prime Day, then resell them without authorization. Because Amazon positions itself as a marketplace rather than a retailer, it does not require seller authorization from the brand.

What are the risks to manufacturers from unauthorized resellers?

Unauthorized resellers can erode retail prices by competing on price alone, create conflict with authorized distributors who see lower prices online, and damage brand reputation by providing poor service or incorrect product information. In some cases, products may be counterfeit, damaged, or improperly stored, creating safety risks that reflect back on the brand.

Can manufacturers take action against unauthorized Amazon sellers?

Yes. Manufacturers with registered trademarks and copyrights can enforce their intellectual property rights through cease-and-desist letters, reporting to Amazon, and if necessary, litigation. Many unauthorized sellers will stop when contacted by legal counsel, and the word spreads among reseller communities when a brand is actively enforcing.

Why do some manufacturers hesitate to enforce against unauthorized sellers?

Common reasons include not realizing they have enforceable IP rights, fear of getting sideways with Amazon, concern about backlash from distributors or customers, uncertainty about which department's budget should cover enforcement, and a belief that enforcement is a whack-a-mole exercise with no lasting impact. In most cases, these concerns are addressable with the right approach.

Does Amazon care whether sellers are authorized by the brand?

Amazon generally does not intervene based on authorization status alone. However, Amazon becomes more receptive when consumer safety is raised as a concern. Manufacturers can work with Amazon to address listings that pose safety risks, especially for products that could be dangerous if counterfeit, improperly stored, or damaged in transit.

What is a MAP policy and how does it relate to brand enforcement?

A minimum advertised pricing policy, or MAP policy, sets a floor on the price at which authorized sellers can advertise a product. Enforcing a MAP policy consistently helps prevent price erosion and supports authorized distribution channels. MAP enforcement is one part of a broader brand protection strategy that may also include monitoring, cease-and-desist programs, and IP enforcement.
