Mastercard treats certain high-risk businesses as “specialty merchants.” If you fall into that category, Mastercard requires you to register for a specific program and pay additional fees that other merchants never have to deal with.
Here’s what that means in practice:
- Your acquirer must register you with Mastercard before you can process Mastercard-branded cards.
- There’s an annual registration fee that applies every year.
- As of June 2026, new fees apply to every Mastercard sale if you’re registered.
- How those costs reach your statement is ultimately up to your processor.
The new costs may appear small. But they add up fast at volume.
And like most network fees, what you actually end up paying depends on how your processor decides to pass them through.
Which Businesses Are Required to Register With Mastercard
According to the latest edition of Mastercard’s Security Rules and Procedures, if your business falls into one of the following categories, your acquirer has to register before you can process anything:
- Adult content and services (CNP): MCC codes 5967 and 7841
- Online gambling and betting: MCC codes 7995, 7801, and 7802
- Online pharmacies primarily offering remote prescription sales: MCC codes 5122 and 5912
- Tobacco and vape products sold online: MCC code 5993
- Government owned lotteries: MCC code 7800 in the US, and 9406 elsewhere
- Skill games (including fantasy sports): MCC code 7994
- High-risk cyberlockers: MCC code 4816
- Binary options, CFDs, forex options, and high-risk securities: MCC code 6211
- Cryptocurrency purchases: MCC code 6051
- Negative option subscriptions for physical products (like supplements and cosmetics): MCC code 5968
- Recreational cannabis in Canada: regardless of MCC code
It’s common for sweepstakes operators to get pulled into this too when their underlying activity falls into one of these categories.
Your acquirer also has to give Mastercard every website URL where these transactions can happen. So if you run more than one merchant account, you’ll need to ask whether each one is registered separately. This matters because the annual fee is billed per registration.
Mastercard Specialty Merchant Fees
For businesses in the US, there are three primary Mastercard Specialty Merchant Registration Fees that you need to be aware of:
- $1,000 annual registration fee per merchant account
- 0.10% (10 bps) of Mastercard volume
- $0.02 on every Mastercard transaction
Mastercard bills all three to your acquirer, who passes them to you.
These charges sit on top of interchange, Mastercard’s regular assessments, and whatever high-risk markup your processor already charges.
Mastercard has historically charged an annual fee to merchants in these categories. But they doubled the fee from $500 to $1,000 effective May 1, 2026. The volume fees and per-transaction fees are both new as of June 3, 2026.
The annual registration fee can be annoying but is honestly a drop in the bucket if you’re doing any real volume. But the two new fees are where things end up costing you.
It’s worth noting that both the transaction and volume fees also apply to refunds. Meaning if you refund a $100 order, you pay 0.10% + $0.02 twice, on the initial transaction, and on the refunded amount. And that’s just the specialty merchant fee component, not your all-in cost.
Do the Fees Apply to All of a Specialty Merchant’s Mastercard Sales?
In most cases, yes. Mastercard flags specialty transactions with a network-level code. And for most categories it assigns that code (P72) based on the merchant.
Mastercard doesn’t see what’s in the cart. It just sees a registered merchant and an amount being charged.
Let’s say you sell vapes online but also sell t-shirts on the same website through the same merchant account. If you’re registered as a specialty merchant, the t-shirt sales carry the same code. Which means you’ll pay the same $0.02 and 10 basis points.
Crypto and high-risk securities work a little differently. For those, the acquirer codes the specific crypto or securities purchases.
That makes your registration status worth checking.
For example, with the tobacco category, that covers merchants whose primary business is selling tobacco online. Whereas a business that sells mostly apparel with a few vape products may not belong in the program at all. That’s your acquirer’s call, and it’s worth asking.
Penalties for Failing to Register a Specialty Merchant
So, what happens if you don’t register?
If Mastercard finds an acquirer processing for a specialty merchant that isn’t registered, the acquirer faces penalties of:
- Up to a $10,000 assessment
- $5,000 per month for up to three months if the merchant isn’t registered within 10 days of the first notice
- $25,000 per month (after the first three months) until this is fixed
As you can see, Mastercard puts the pressure on acquirers in this scenario. That’s why yours might be asking you for additional paperwork if they think there’s a chance you’re in any of these categories.
Though Mastercard can also treat the merchant as violating its rule on illegal or brand-damaging transactions, which would put the merchant account itself at risk.
How Specialty Merchant Registration Drives Up Other Processing Costs
The 0.10% + $0.02 per transaction and a $1,000 annual fee is only part of the cost that you can see. Mastercard also made it more expensive and riskier for acquirers to take on specialty merchants at all.
Here’s what acquirers are dealing with now:
- $50,000 annual license fee
- Express written consent from Mastercard before taking on a specialty merchant at all (as of May 1, 2026)
- Penalty exposure (mentioned above), starting at $10,000 and climbing to $25,000 per month if not resolved
- Ongoing compliance work to collect licenses, legal options, independent certifications, etc.
And your acquirer isn’t going to eat those costs. They’re guaranteed to make their way to your statements in one form or another.
Another Layer That Can Increase Your Costs
Additionally, many specialty merchants can’t go through traditional payment processors. If you couldn’t get standard processing and had to get a dedicated high-risk merchant account, you may have an ISO or PayFac sitting between you and the acquirer.
Mastercard’s own rules for this program reference ISOs, so the structure is obviously common enough to be written into those standards.
But every party in the chain has to get paid. The acquirer has to cover its $50,000 license, compliance costs, plus the regular risks of dealing with high-risk transactions. And the ISO has to earn its margin on top.
Each additional layer is a chance for the Mastercard fees and everything surrounding them to get marked up again before they reach your statement.
So will you see the $1,000 annual fee on your statement? Potentially. But you may not be able to identify every other markup that’s also a result of Mastercard’s Specialty Merchant Registration Program.
I can practically guarantee those charges are in your statement somewhere, though they aren’t always obvious.
