Brands control wholesale distribution by combining a written selective distribution policy, individual buyer vetting, signed reseller agreements, and active channel monitoring. Each of these four pieces plugs a different leak, and any brand missing one of them will eventually see products land in places they did not authorize.
This article walks through the exact structure emerging consumer brands use to decide who gets to buy at wholesale, how to write the rules down, and how to enforce them once inventory leaves the warehouse.
Why channel control matters more as a brand grows
Early on, most brands say yes to every wholesale inquiry that arrives. The revenue is real, the buyer sounds legitimate, and there is no time to run a background check on a 20-unit order. Six months later, the same brand finds its product on Amazon at 40% below MAP, sold by a seller nobody recognizes, with negative reviews from customers who received units past expiration.
The math changes as volume grows. Every unsanctioned reseller compresses margin for authorized accounts, and every authorized retailer starts asking why they are being undercut.

What is a selective distribution policy?
A selective distribution policy is a one to three page document that states the objective criteria a retailer must meet to buy your product at wholesale, and the conditions under which that authorization can be revoked. It is unilateral. You publish it, and retailers either qualify or they do not.
Typical criteria include:
- A physical or verified ecommerce storefront with the brand present alongside comparable products
- Trained staff or accurate product education content on the retailer’s site
- Approved sales channels (for example: own website, brick and mortar, sometimes Amazon under a separate approval)
- Compliance with MAP pricing
- No sales to other resellers (an anti-diversion clause)
- Adequate customer service infrastructure for returns and warranty claims
The policy protects the brand’s ability to refuse or terminate accounts without triggering antitrust exposure, provided the brand acts on its own rather than in agreement with other retailers.
The Colgate doctrine and what you can legally require
The 1919 Supreme Court decision in United States v. Colgate & Co. established that a manufacturer acting alone can announce the terms on which it will sell and refuse to deal with anyone who does not meet them. This is the legal foundation for MAP policies and selective distribution in the U.S.
The limits: the brand cannot enter horizontal agreements with competing retailers to fix prices, cannot punish and then reinstate a retailer based on promises to comply (that starts to look like an agreement), and must apply the policy consistently. Enforcement is binary. You stop selling to a violator, or you keep selling. Negotiating the violation away weakens the policy.
Consult a distribution or antitrust attorney before publishing. State laws (notably Maryland for MAP) add wrinkles.
Vetting retailers before the first order ships
A selective distribution policy is only as good as the intake process behind it. Most brands vet wholesale applicants across five points:
- Business legitimacy. Resale certificate, EIN, business license, and a matching address.
- Sales channels. Where will they list your product? Own site, physical store, Amazon, Walmart, eBay, TikTok Shop. Each channel gets a separate yes or no.
- Product fit. Does the retailer’s assortment match your positioning? A premium skincare brand next to $2 impulse items sends the wrong signal.
- References. Two other brands they currently carry, contacted directly.
- Order profile. Minimums, expected reorder cadence, and payment terms.

The reseller agreement: what to include
Every approved retailer signs a reseller agreement before the first PO is accepted. This is separate from your terms and conditions and separate from your MAP policy. It is the contract that binds a specific buyer to a specific set of channel rules.
Core sections:
- Approved channels. List each URL, storefront, and marketplace by name. Anything not listed is not approved.
- Geographic scope. Country, region, or territory limits if any.
- MAP terms. Reference your MAP policy and require acknowledgment.
- Trademark and marketing use. What images, copy, and logos they may use, and where.
- Anti-diversion. Explicit prohibition on selling to other resellers, jobbers, or unauthorized third parties.
- Serialization and traceability. Right to require lot or unit tracking to trace diverted product back to source.
- Audit rights. You can request sales channel reports.
- Termination triggers. Which violations end the relationship, and what happens to remaining inventory.
- Minimum order quantity and reorder cadence. Filters out one-time buyers looking to flip.
The agreement is not filler. When you find your product on an unauthorized Amazon listing, the anti-diversion clause and audit rights are the paper trail that lets you identify the leaking account and close it.
Enforcement: monitoring, test buys, and removal
Rules without enforcement produce a policy nobody respects. Ongoing channel control has three parts.
Monitoring. Use a MAP monitoring tool or a manual weekly sweep of Amazon, Walmart, eBay, and Google Shopping for your top SKUs. Log every seller and price. See our guide on how to enforce MAP pricing with wholesale retailers.
Test buys. When an unknown seller appears, buy one unit. The lot code, serial number, or packaging batch identifies which authorized wholesale account shipped it. That account gets a violation notice and, on repeat, termination.
Removal. Enroll in Amazon Brand Registry (requires a registered trademark). Brand Registry gives you the tools to report listing violations, remove counterfeit or unauthorized listings using your trademarks, and submit test buy evidence for enforcement.

Using a vetted marketplace to reduce screening load
Manual vetting scales badly. A brand doing 20 wholesale conversations a week spends more time saying no than shipping product. This is the problem a gated B2B marketplace addresses.
Instead of every applicant reaching your inbox, a marketplace like Catalist AI pre-screens retailers, verifies licenses and channels, and only surfaces buyers that fit your published criteria. The brand keeps final approval on every account but skips the first three steps of vetting. See wholesale distribution platforms for emerging brands and best invite-only wholesale platform for Amazon sellers for how gated platforms structure the filter.
A marketplace does not replace your selective distribution policy or your reseller agreement. It reduces the volume of unqualified applications that reach those documents, so the documents actually get used.
Putting it together
Channel control is a system, not a single document. The policy defines who qualifies. The vetting process confirms each applicant fits. The reseller agreement binds the buyer to the rules. Monitoring and enforcement close the loop. Drop any one piece and inventory finds its way to sellers you did not choose.
