Three acronyms show up in nearly every distribution agreement, and brand owners use them interchangeably far more often than they should. MSRP is a suggestion. MAP is a floor under the advertised price. UPP is a floor under the actual selling price. Each one asks something different of a reseller, and each one is enforced differently. Choosing between them is a channel decision before it is a legal one.
This guide defines the three policies, shows how each is enforced, and then covers the moment when a brand outgrows one and needs the next. Nothing here is legal advice. Before publishing any pricing policy, have counsel review it against your own products and the markets you sell into.
The three definitions
MSRP: the suggestion
MSRP stands for manufacturer's suggested retail price. It is the number the brand prints on the box and on the line sheet. It carries no obligation. A reseller can sell at MSRP, above it, or well below it, and the brand has agreed to nothing that would stop them. The Federal Trade Commission's own guidance on manufacturer imposed requirements puts it plainly: the key word is suggested, and a dealer is free to set the retail price of the products it sells.
MAP: the floor under the advertised price
MAP stands for minimum advertised price. The brand announces, on its own, the lowest price at which its products may be advertised, and attaches consequences for advertising below it. The policy governs what the reseller shows the world, not what the reseller ultimately charges at checkout. A store can ring up a lower number at the register without touching the policy in most drafts. Our primer on what MAP pricing means covers the definition and a worked example in more depth.
UPP: the floor under the selling price
UPP stands for unilateral pricing policy. The name describes the legal structure rather than what the policy controls, which is why the term confuses people. In practice, brands use UPP to mean a floor under the actual selling price rather than the advertised one. Where MAP says "do not show a price below this number," a UPP says "do not sell below this number," closing the gaps MAP leaves open, such as cart discounts and the checkout price on a marketplace listing.
Because UPP reaches the transaction price, it sits closer to resale price maintenance than MAP does, and the legal review that precedes it tends to be more careful. More on that below.
How each policy is enforced
MSRP is not enforced. There is nothing to enforce. A brand that wants resellers to hold MSRP has, in effect, already decided it wants a MAP or a UPP and has not written it down yet. The FTC guidance notes that a manufacturer can decline to use distributors that do not adhere to its MSRP, but that is an unwritten unilateral policy with none of the clarity a written one provides.
MAP is enforced by watching advertised prices. The brand or its agent watches listings and ads for a displayed price below the floor, documents it, sends notice, and applies the consequence the policy names. The evidence is a screenshot of an advertised price. The reseller's defense is usually "that was a cart price, not an advertised price," which is exactly why the definition of advertising in the policy matters so much. The enforcement playbook covers the operational ladder for marketplace listings.
UPP is enforced by watching selling prices. The evidence is a receipt or a checkout screen. That is harder to gather at scale than a screenshot of a listing, but it removes the cart price defense entirely. A UPP is also typically enforced without notice and cure steps. The brand states the consequence in advance and applies it when it sees a violation. There is no negotiation, because negotiation would turn the unilateral policy into an agreement.
In all three cases the final consequence is the same: the brand stops supplying the reseller. Every other step in a violation ladder is on the way to that decision.
The legal framing, at a high level
US antitrust practice draws a line between a brand deciding on its own whom it will sell to, and a brand agreeing with resellers on the price they will charge. The first is a unilateral decision. The second is a vertical price agreement, and it gets a very different level of scrutiny.
The unilateral side traces back to a 1919 Supreme Court decision, United States v. Colgate & Co., which held that in the absence of any purpose to create or maintain a monopoly, a manufacturer engaged in an entirely private business may exercise its own independent discretion as to the parties with whom it will deal, and may announce in advance the circumstances under which it will refuse to sell. That principle, usually called the Colgate doctrine, is why MAP and UPP policies are written as announcements rather than contracts. The brand states the policy, states the consequence, and decides on its own whether to keep supplying each reseller.
The agreement side changed in 2007. The FTC guidance summarizes it: the Supreme Court determined that manufacturer imposed vertical price programs should be evaluated using a rule of reason approach rather than being treated as automatically illegal. The same guidance adds two cautions. Some state antitrust laws still treat minimum price rules as illegal per se, and international authorities often take a stricter view than US federal courts do.
What this means in practice for a brand choosing among the three:
- MSRP raises no antitrust question on its own, because it obligates nobody.
- MAP is generally treated as the lower risk structure, because it reaches advertising rather than the sale itself. It still needs to be written and run as a unilateral policy to stay on that ground.
- UPP reaches the selling price, which brings it closer to resale price maintenance. Brands that adopt one usually involve counsel from the first draft and never negotiate terms with individual resellers.
What erodes the unilateral structure is conduct: discussing the floor with a reseller, or promising leniency for a larger order. An announcement can become an agreement that way, and the legal analysis changes with it.
When a brand moves from MSRP to MAP to UPP
A common path is to graduate through the three as the channel grows and the problems change.
MSRP only: one channel, few resellers
A brand selling through its own website and a handful of boutiques usually runs on MSRP alone. The resellers are known and nobody is discounting because nobody has a reason to. A MAP policy at this stage is paperwork without a problem to solve.
The trigger for MAP: a second reseller advertises below the first
MAP becomes necessary the first time two resellers advertise the same product at different prices and the higher priced one calls to complain. The retailer investing in shelf space or paid advertising cannot keep doing it while a discounter undercuts the number they show customers. A MAP policy gives the brand a consistent written answer and gives every reseller the same floor to plan around. The MAP strategy guide covers how to set the number and how the policy fits a wider channel design.
The trigger for UPP: the advertised floor holds and the selling price does not
UPP becomes the conversation when resellers have learned to comply with the letter of MAP while defeating its purpose. The listing shows the floor. The cart shows something else. A bundle arrives priced so that the product inside it is effectively below the floor. A marketplace seller displays MAP and then applies a promotional discount at checkout. Each of these is arguably compliant with a policy that only governs advertised prices, and each of them puts the honest reseller back where they were before the MAP policy existed.
The brand then has two choices: tighten the MAP policy's definition of advertising until it covers cart prices and coupons, which brands typically try first, or move to a UPP that governs the selling price directly. The second route is easier to enforce and harder to adopt.
How marketplaces change the picture
The advertised versus selling price distinction was built for print ads and store shelves, where the two could genuinely differ. On a marketplace listing, the displayed price is the advertisement and, in most cases, the transaction price. The same collapse happens on Amazon, Walmart Marketplace, eBay and any other venue where the listing price is the checkout price.
MAP behaves almost like UPP on a marketplace. Because the listed price is what the customer pays, holding the advertised floor and holding the selling price become nearly the same act. A brand selling mostly through marketplace listings gets most of UPP's practical effect from a MAP policy that explicitly covers listings and cart prices.
The gaps that push brands toward UPP are marketplace features. Clipped coupons, subscription discounts and promotional codes all lower the price a customer pays without changing the number displayed at the top of the page. A MAP policy that is silent on these features will be defeated by them. A policy that names them stays a MAP policy while closing most of the distance to a UPP.
Marketplaces do not enforce any of the three for you. A marketplace has its own pricing rules, built around the customer's interest in a low price rather than the brand's interest in a floor. Enforcement there is the brand's job: find the seller under the floor and trace that seller's supply back to an authorized account. Our guide on unauthorized sellers covers the tracing side.
Choosing the policy that fits
A short way to decide:
- If no reseller is discounting and you talk to every account personally, MSRP is enough for now. Draft the MAP policy anyway so it is ready when the first complaint arrives.
- If resellers are advertising different prices and the full service accounts are pushing back, adopt MAP. Write the definition of advertising broadly enough to cover marketplace listings and cart prices from day one.
- If advertised prices hold and selling prices do not, tighten MAP first. If that fails, and the channel is mostly independent retail rather than marketplace, take the UPP conversation to counsel.
Whichever policy you land on, the same thing keeps it defensible. The brand decides alone, announces in advance and applies the consequence every time.

Get in TouchFrequently asked questions
What is the difference between MAP and MSRP?
MSRP is the price a brand suggests, with no obligation attached. MAP is the lowest price a reseller may advertise, set by the brand in a unilateral policy with consequences for going below it. A product can carry both at the same time, with MAP sitting below MSRP to leave room for promotions.
What is the difference between MAP and UPP?
MAP governs the advertised price. UPP, as brands use the term, governs the actual selling price, including cart discounts and checkout prices. UPP closes the gaps that a MAP policy leaves open, and because it reaches the transaction price, it usually gets closer legal review before adoption.
Is UPP the same as resale price maintenance?
Not when it is structured as a unilateral policy that the brand announces and enforces on its own, without agreements with resellers. Resale price maintenance, in the legal sense, involves an agreement on price between the brand and the reseller. The distinction turns on conduct, and it is one to work through with counsel rather than assume.
Can a brand have a MAP policy and a UPP at the same time?
Brands do run both, typically a UPP for a core line where the selling price must hold and MAP for the rest of the catalog. Running two policies doubles the monitoring and the documentation, so brands typically start with one and add the second only when the first has a specific gap they cannot close by rewriting it.
Does MAP apply to Amazon and other marketplaces?
Only if the policy says so. A well drafted MAP policy names marketplace listings and cart prices explicitly as forms of advertising. On a marketplace the displayed price is usually the transaction price, so a MAP policy that covers those mechanics delivers most of what a UPP would, without the additional legal weight.
Who enforces MAP or UPP on a marketplace?
The brand or its authorized distributor. Marketplaces do not police a brand's price floor. Enforcement means documenting the seller under the floor, sending the notice the policy calls for, and tracing that seller's inventory back to an authorized account.
