What is MAP pricing?
MAP pricing means minimum advertised price: the lowest price a manufacturer’s policy allows its resellers to advertise for a product. It limits the price shown in a listing or ad, not necessarily the price a customer finally pays. The exact rules come from each manufacturer’s written policy. MAP is a manufacturer’s policy, not a law.
Key takeaways · if you read nothing else
- MAP stands for minimum advertised price, and it limits the advertised price of a product, not necessarily the final selling price.
- The manufacturer sets MAP part by part, and its written policy decides what counts as advertising and which exceptions apply.
- A dealer listing below MAP is only a potential issue until the exact part, the MAP in effect on that date and the policy’s exceptions have been checked.
- The FTC distinguishes a manufacturer’s unilateral pricing policy (lawful) from a collective agreement among competitors (unlawful), and notes that some state laws are stricter.
- Monitoring MAP means checking listings, one part number at one dealer, so 25 parts across 5 dealers is 125 listings to watch.

What does MAP stand for, and what does it limit?
MAP stands for minimum advertised price. It sets a floor on the price a reseller shows, such as the price on a dealer’s product page or in an ad, under the terms of the manufacturer’s MAP policy.
Not the selling price
MAP is about what’s advertised. Whether a lower price in the cart, at checkout or over the phone counts as “advertised” depends on the policy’s wording.
Not MSRP
MSRP is a suggested retail price. MAP can equal MSRP or sit below it; the manufacturer’s price sheet says which. See MAP vs MSRP.
Not a statute
No law sets a MAP. It exists because a manufacturer wrote a policy, and that policy’s terms are the reference.
You’ll also see iMAP (internet MAP), which usually means a MAP policy that applies to online advertising, and UPP (unilateral pricing policy), which usually goes further and covers the resale price itself. Usage varies by manufacturer, so read the term in the policy you’re working with. The glossary of MAP, iMAP, UPP and MSRP compares them.
Who sets MAP, and where does it apply?
The manufacturer sets MAP. It decides which parts have a MAP, what the amount is for each one, which sellers and channels the policy covers and what happens when an advertised price falls below it.
In the aftermarket, that usually shows up as two documents:
MAP policy
Who it applies to, what counts as advertising, exceptions (bundles, coupons, promotions, dates) and how the manufacturer responds
Decides whether a low price is a problem at all
MAP price sheet
A MAP amount for each manufacturer part number (MPN), with an effective date
Decides which number a listing is compared against
Both change over time. A new price sheet can raise or lower MAP on a set date, and the old number stays relevant for anything captured before that date (more on this below). How a policy turns into a working process, from scope and versioning to dealer communication, is covered in what a MAP pricing policy must operationalize.
How the manufacturer chooses each MAP amount is its own business decision. This guide doesn’t recommend a formula.
How does MAP pricing work? One part across five dealer listings
MAP is applied one listing at a time: one part number on one dealer’s site, compared against the MAP in effect when the price was captured. Here’s what that looks like for a single part.
Illustrative example: fictional manufacturer, dealers and part numbers. Not a real MAP violation or real pricing.
Sample Manufacturer Co. sells EXM-CAI-4120-BK, a cold-air intake kit in black. MAP is $449.00 under MAP policy v2, effective Mar 1, 2026. Prices were captured on Oct 6, 2026, between 9:02 and 9:31 a.m. CT.
Five fictional dealer listings for one intake kit plotted against a $449.00 MAP line: one below, one at, one above, one bundled and one that couldn't be checked. Part EXM-CAI-4120-BK, MAP $449.00 (Policy v2 · effective Mar 1, 2026). Dealer A: $412.99, Potential below-MAP observation, after review. Dealer B: $449.00, At MAP. Dealer C: Could not check (HTTP 403). Dealer D: $429.00, Bundled with a filter kit · policy question. Dealer E: $449.95, Above MAP.
- Only Dealer A gives a clean comparison. It’s the exact part, a plain advertised price and the MAP in effect that day. The arithmetic is $412.99 − $449.00 = −$36.01, and −$36.01 ÷ $449.00 = −8.0% of MAP. Even so, it’s a potential observation. Whether it breaches the policy is the manufacturer’s call.
- Dealer D shows why the policy matters. Against the intake’s MAP alone, $429.00 is $20.00 below. Against a combined MAP for the intake and its filter kit ($449.00 + $69.00 = $518.00), it’s $89.00 below. Same listing, two honest numbers; the policy decides which comparison applies.
- Dealer C is a gap, not a pass. A page that couldn’t be read tells you nothing about its price. A useful record says so instead of counting it as fine.
Try it with your own numbers
Subtract MAP from the advertised price. A negative result means the advertised price is below MAP. For example, an ad at $171.99 against a $189.00 MAP is $171.99 − $189.00 = −$17.01, or −9.0% of MAP. That number is a starting point for review, not a conclusion.
Numbers only · no verdicts · nothing is savedWhich prices does MAP cover?
MAP always covers the price advertised on the listing itself. Almost everything else depends on how the manufacturer’s policy is written, which is why two brands can treat the same dealer page differently.
| What the shopper sees | Covered by MAP? |
|---|---|
| The price displayed on the product page | Yes. This is the advertised price MAP is about. |
| A price shown only after “add to cart” | Depends on the policy’s definition of advertising |
| A coupon code shown beside the price | Depends on the policy. Some treat an advertised code as advertising the lower price. |
| A bundle or kit sold with other items | Depends on the policy and on whether the bundle has its own MPN and MAP |
| A “% off” badge or a struck-through MSRP | Depends on the policy; the displayed price still has to be checked against MAP |
| An ad inside a promotional period the policy defines | Follows the policy’s terms for that window |
| A price quoted by phone or email to one customer | Usually outside “advertised”, but read the policy |
For aftermarket parts, three catalog problems cause most confusion before price even comes into it:
Finishes and configurations
Black and polished versions can be different MPNs with different MAPs.
Kits
A kit can carry its own MPN and MAP, separate from its components.
Superseded part numbers
An old MPN can stay listed after the price sheet moves to a new one.
A price only means something once the listing is matched to the exact part on the current sheet. The advertised vs. cart price guide works through these cases in detail.
Why do manufacturers use MAP?
Manufacturers use MAP to set a floor on how their products are advertised, while leaving the final selling price to the dealer.
The reasoningThe FTC’s guidance explains the reasoning behind minimum price rules generally. An agreement to set minimum (“floor”) prices “may encourage dealers to provide a level of service that the manufacturer wants to offer to consumers when they buy the product.”
FTC · Manufacturer-imposed Requirements
Free ridingThe same guidance quotes the Supreme Court’s concern about free riding. Without such restraints, “discounting retailers can free ride on retailers who furnish services and then capture some of the increased demand those services generate.”
FTC · Manufacturer-imposed Requirements
The trade-offIt also notes the trade-off: restrictions on dealers can reduce competition among dealers selling the same brand, and those benefits “must be weighed against any reduction in competition from the restrictions.” That weighing is a legal question, covered next.
FTC · Manufacturer-imposed Requirements
Checking takes work
Even a small scope adds up: 125 listings checked daily is about 3,750 checks a month.
Every response involves a dealer you still sell to
Acting on a weak or mistaken observation costs goodwill, which is why evidence matters.
The policy needs care
The wording decides what counts, and counsel should review how it’s set up and applied.
Is MAP pricing legal?
Under U.S. federal law, there’s no blanket yes or no: it depends on how the policy is set up and applied. These points come from the FTC’s own guidance page, Manufacturer-imposed Requirements:
Unilateral vs. agreed“The critical distinction is between a unilateral decision to impose a restraint (lawful) and a collective agreement among competitors to do the same (unlawful).”
FTC · Manufacturer-imposed Requirements
A manufacturer acting on its own“If a manufacturer, on its own, adopts a policy regarding a desired level of prices, the law allows the manufacturer to deal only with retailers who agree to that policy. A manufacturer also may stop dealing with a retailer that does not follow its resale price policy.”
FTC · Manufacturer-imposed Requirements
Federal vs. stateIn 2007, the Supreme Court determined that “all manufacturer-imposed vertical price programs should be evaluated using a rule of reason approach.” The FTC adds that “some state antitrust laws and international authorities view minimum price rules as illegal, per se.”
FTC · Manufacturer-imposed Requirements
Dealer complaints“A manufacturer can listen to its dealers and take action on its own in response to what it learns from them.” Problems may arise “if it appears that the dealers have agreed to threaten a boycott or collectively pressure the manufacturer.”
FTC · Manufacturer-imposed Requirements
MAP in co-op advertisingThe law gives a manufacturer “considerable leeway in setting the terms for advertising that it helps to pay for.” The FTC has also challenged MAP policies it found “unreasonable in their reach.”

This is general information, not legal advice. MAP policies and their enforcement can raise antitrust issues; talk to qualified counsel about your policy.
Can a dealer sell below MAP?
Often, yes. MAP limits the advertised price, so a lower final price isn’t automatically outside the policy.
Whether a cart-only price, a coupon or a negotiated quote is allowed depends on the manufacturer’s policy. Dealers should read their manufacturers’ policies, and manufacturers should make the wording clear.
What happens when a dealer listing is below MAP?
A listing below MAP is a starting point, not a verdict. Before it’s worth raising with anyone, four things should line up:
- Exact match. The listing is the same MPN and variant as the MAP row: same finish, same kit.
- Right MAP. The MAP row was in effect on the capture date. If the sheet changed on Mar 1, a February capture is compared with the old number.
- Advertised price. The price was displayed on the listing, recorded as shown and timestamped.
- No exception. Nothing in the policy covers it, such as a bundle, a coupon rule or a promotion window.
Illustrative example: fictional part and policy versions. Not real pricing.
| Policy version | Effective | MAP for EXM-CAI-4120-BK |
|---|---|---|
| v1 | Sep 1, 2025 | $429.00 |
| v2 | Mar 1, 2026 | $449.00 |
A dealer advertising $429.00 was at MAP on Feb 20, 2026 and $20.00 below MAP on Oct 6, 2026. Same listing, same price, different answer. Comparing every capture against today’s sheet gets one of them wrong.
What the manufacturer does next is its own decision under its policy. The MAP pricing violations guide walks through six real-world-style cases (fictional data) and the evidence each one needs.
How do manufacturers monitor MAP?
Monitoring MAP means checking listings: the exact product pages where your part numbers appear at each dealer. Scope is counted in listings, not part numbers.
25 priority MPNs across 5 dealers is 25 × 5 = 125 listings, and checking each one daily comes to about 3,750 checks a month.
Manual spot checks
You visit dealer pages yourself. This works for a handful of listings, but gaps are easy to miss and hard to document.
Software
A self-service tool collects prices and you run the review. Ask any vendor what it counts as a listing, how it matches part numbers and how it reports failed checks.
A managed service
Someone else matches, checks and reviews, and sends you the evidence.
Whichever you choose, each observation is only useful with these fields:
| Field | Example (illustrative) |
|---|---|
| Listing and dealer | Dealer A product page for EXM-CAI-4120-BK |
| Match | Verified exact MPN and finish |
| Advertised price, as shown | $412.99 |
| Captured at | Oct 6, 2026, 9:14 a.m. CT |
| MAP row and policy version | $449.00, policy v2, effective Mar 1, 2026 |
| Result | Completed check, or the reason it failed (blocked, not found, timeout) |
For how collection, matching and review fit together, see how MAP monitoring works across retailer sites.
We monitor an agreed list of independent online parts dealers for your priority part numbers. Each listing is matched to the exact MPN before it’s compared with the MAP in effect on the capture date. A person reviews every potential below-MAP observation, and you get the evidence in a weekly report, including the checks that couldn’t be completed. We don’t contact dealers, cover marketplaces or make legal calls.
FAQ
Does MAP apply on Amazon and other marketplaces?
It can, if the manufacturer’s policy covers them; the policy decides. Marketplace listings raise their own questions about which seller made which offer. Price Axle’s pilot covers independent dealer sites, not marketplaces. The MAP on Amazon guide explains what public observations can and can’t show.
Is MAP the same as a price floor?
It’s a floor on the advertised price under the policy’s terms. It isn’t a floor on the final selling price unless the policy goes further, and that’s when UPP and the legal questions above come in.
Who decides whether a below-MAP listing breaches the policy?
The manufacturer, under its own policy and with its counsel where needed. Monitoring provides the evidence; it doesn’t make the call.
