Are you fulfilling Shopify and TikTok Shop orders out of your FBA stock without getting the 35% discount? Most sellers doing exactly that have no idea the money is on the table.
Amazon MCF for Shopify and TikTok Shop orders is simple to switch on and easy to misconfigure, which is why so few brands know what theirs actually costs. This guide gives you the full picture, from what Amazon charges to which orders qualify for a discount and which channels belong on MCF at all.
We have managed $1.2B+ in ecommerce revenue across 400+ brands, and the same lesson keeps surfacing. The cost problem is rarely the fee itself and almost always the routing, so understanding how orders reach Amazon matters more than memorizing a rate card.
Our Amazon agency covers MCF fee math, discount eligibility, and channel routing in this guide. We also work through TikTok warehouse compliance, restock limit effects, and the numbers that prove the channel is paying for itself.

TL;DR - Amazon MCF for Shopify and TikTok Shop Orders
Amazon MCF fulfills your Shopify and TikTok Shop orders from the same FBA stock that serves your Amazon listings. What it costs depends less on the rate card than on how each order reaches Amazon.
- One inventory pool serves every channel
- Peak fulfillment fees start October 15
- The 35% TikTok discount requires order attribution
- Manual and legacy-app orders pay full price
- Bulky SKUs usually belong with a 3PL
The same 6 oz unit costs about $7.61 shipped from Shopify and about $4.95 shipped from TikTok Shop when the order is attributed correctly. At 2,000 orders a month, that spread is roughly $5,300 decided by configuration alone.
10 Reasons To Choose FBA over FBM (And When Not To)
What Is Amazon MCF and How Does It Work?
Amazon Multi-Channel Fulfillment lets you ship orders from Shopify, TikTok Shop, and other off-Amazon channels using the FBA inventory already sitting in Amazon’s warehouses. Nothing moves, and nothing gets duplicated, because MCF and FBA draw from one shared pool and use the same picking and packing operation.
The connection runs through an app or integration that passes each order from your selling channel into Amazon, then returns the tracking number to the customer. That turns Amazon into a logistics provider for your whole catalog rather than a fulfillment service for your Amazon listings alone.
How Amazon MCF Works for Shopify and TikTok Shop Orders
Amazon MCF ships your off-Amazon orders out of the same FBA stock that serves your Amazon listings. Nothing moves, nothing gets duplicated, and no second warehouse relationship gets signed.

The referral fee row is the one operators miss when they build the model. An off-Amazon sale skips the 15% cut, which is why a Shopify order can out-earn the identical Amazon order even while carrying a higher fulfillment fee.
Can I Use My Amazon FBA Inventory To Fulfill Shopify Orders?
Yes, and you can do it without selling on Amazon at all. Amazon’s Shopify integration setup guide offers a standalone MCF account for brands that want the fulfillment network and nothing else.
For everyone already running FBA, the single pool is the whole argument. Amazon reports that sellers using both programs cut out-of-stock rates by 19% and improved inventory turnover by 12%, based on trailing data from 590,000 sellers.
What Does Amazon MCF Not Cover?
MCF is a last-mile service wearing a full-service costume. It does not handle inbound freight, customs clearance, FBA prep, branded unboxing, or reverse logistics.
Some of those gaps close inside Amazon’s own network, since Amazon Warehousing and Distribution covers upstream bulk storage and replenishment into FBA. The rest need a partner, so solve them before you commit a channel rather than discovering the returns gap in week two of Q4.
What Amazon Multi-Channel Fulfillment Costs Before Q4
MCF pricing runs on product size tier, shipping weight, units per order, and delivery speed. Two additional charges sit on top of that base rate, and both of them landed in 2026.
Why Are My Amazon MCF Fees Higher Than My FBA Fees?
Amazon widened the gap deliberately on January 15, 2026, when most single-unit orders rose by $0.35 to $0.41 per unit. A 3.5% fuel and logistics surcharge then applies to US MCF fees on top of that new base.
The seasonal layer is the one that catches operators off guard. Amazon’s MCF pricing page confirms holiday peak fulfillment fees run October 15, 2026 through January 14, 2027, with the surcharge stacked on those elevated rates.
Amazon MCF Fees by Size Tier and Delivery Speed
Fees are set by size tier, shipping weight, units per order, and delivery speed. The table below shows single-unit rates from Amazon’s MCF peak rate card, which is the window your Q4 orders will ship in.
| Size tier and weight | Standard (3 days) | Expedited (2 days) |
|---|---|---|
|
Small standard, 4 oz or less
|
$7.18
|
$10.38
|
|
Small standard, 8 to 12 oz
|
$8.01
|
$11.13
|
|
Large standard, 4 oz or less
|
$7.44
|
$10.60
|
|
Large standard, 1 to 2 lbs
|
$10.60
|
$13.37
|
|
Large standard, 2 to 3 lbs
|
$11.75
|
$14.12
|
|
Large bulky, up to 30 lbs
|
$18.59 plus $0.73 per lb over 2 lbs
|
$20.21 plus $0.73 per lb over 2 lbs
|
Units per order is the biggest lever on this card, and almost nobody pulls it. That same small standard 4 oz item drops to $3.83 per unit in a four-unit order, which is a 47% cut for doing nothing but bundling.
The Cost Gap Between a Shopify Order and a TikTok Shop Order
Take a 6 oz small standard item shipping Standard, which bills at $7.35 before surcharges. On Shopify, you add the 3.5% fuel and logistics surcharge and land at roughly $7.61 per order.
That same unit sold on TikTok Shop and attributed correctly runs about $4.95 after the 35% discount. At 2,000 orders a month, the spread is roughly $5,300 you either capture or hand back, decided entirely by whether your connector passes the channel field.
The Three Amazon MCF Discount Programs and Who Qualifies
Three discount programs exist, and they do not all combine. Read the middle column before you assume anything applies to your account.
| Program | Benefit | The catch |
|---|---|---|
|
TikTok Shop promotion
|
35% off Standard and Expedited
|
Attributed orders only, US addresses
|
|
2026 Preferred Pricing
|
Up to 15% off plus $1 FBA credit per unit
|
Ends at 12 months or 100,000 units
|
|
New Seller Incentive
|
25% off first 100 units
|
One-time, new accounts
|
Preferred Pricing runs on rolling volume, so your tier recalculates as your shipping pattern changes. TikTok orders replace the Preferred Pricing discount rather than stacking with it, though those units still count toward your volume thresholds without draining your benefit cap.
Amazon MCF vs 3PL Fulfillment Compared
The choice is rarely one or the other, and it is never decided at the brand level. Four factors settle it per SKU, which are unit economics after surcharges, the delivery promise your channel makes, whether branded packaging is part of your offer, and how often the item comes back.
| The decision | Amazon MCF wins | A 3PL wins |
|---|---|---|
|
Order volume
|
Below a 3PL minimum you cannot fill
|
Steady volume that earns negotiated rates
|
|
Product size
|
Small and large standard
|
Bulky, heavy, or oversized
|
|
Packaging |
Plain box is fine
|
Branded unboxing drives repeat purchase
|
|
Returns |
Low return rate
|
High return rate needing inspection
|
|
Destination |
Domestic US orders
|
International, freight, or customs
|
Standard-size domestic orders usually favor MCF because you are reusing a network you already fund. The math flips fast on bulky items, since a 30 lb order starts at $18.59 before surcharges and a 3PL with negotiated carrier rates will often beat that.

The Attribution Rule Behind Your 35% TikTok Shop Discount
Amazon began offering 35% off Standard and Expedited MCF rates for US TikTok Shop orders on July 16, 2026, for at least twelve months. The promotion needs no enrollment, which is exactly why so many sellers assume they already have it.
Why Is My TikTok Shop Discount Not Showing Up?
The word doing the work in Amazon’s terms is “attributed”. Your order has to reach MCF carrying proof that it came from TikTok Shop, and that proof only travels through a supported integration partner.
Three causes account for nearly all of the failures we see. Orders keyed in manually through Seller Central are explicitly excluded, an unsupported connector strips the channel field, and the legacy Shopify app does not pass origin data at all.
What Happens to the Legacy Shopify App on September 30, 2026?
Amazon deactivates the older MCF: US Fulfillment app for Shopify on that date. Brands still running it need to install the MCF and Buy with Prime app, migrate SKU mapping by CSV export, and rank Amazon Fulfillment above Amazon MCF in Shopify order routing.
Skipping the migration costs you twice over. You lose the 35% discount on every TikTok order routed through Shopify, then you lose fulfillment entirely once the app goes dark.

How to Set Up Amazon MCF for Shopify
Amazon’s free app handles the connection directly, so most brands need no third-party middleware for Shopify alone. Setup takes an afternoon, and the failure points are predictable.
- Connect your Amazon selling account inside the MCF and Buy with Prime app
- Map Shopify SKUs to Amazon SKUs, one at a time, since no bulk tool exists
- Build a dedicated shipping profile and map each rate to an MCF speed
- Automate submission through Shopify Flow or automatic fulfillment settings
- Rank Amazon Fulfillment above Amazon MCF in order routing
- Place a test order and confirm it appears in Seller Central before going live
Two constraints deserve a note in your SOP. MCF rejects any order above 250 units or 100 unique SKUs, and inbound stock is invisible to the app until Amazon receives it.
Amazon vs Shopify
How to Set Up Amazon MCF for TikTok Shop
TikTok confirmed MCF as a supported fulfillment path in early 2026 after months of uncertainty. The configuration now depends entirely on whether your shop retained Seller Shipping access.
- Check your Seller Shipping status, because shops that still have it need no warehouse setup
- Connect an integration that attributes orders, such as WebBee, AfterShip, Rithum, or LINGXING
- Designate one central fulfillment center address if you lack Seller Shipping
- Set the provider to Amazon Shipping plus Amazon MCF and pass the MCF tracking number
- Point your returns address at a location you control, never an Amazon warehouse
- Run one manual return end to end so your team knows the workflow
Amazon’s TikTok Shop fulfillment guide names CMH2 in Groveport, Ohio as a sample central address. Returns cannot point at Amazon because inventory gets routed dynamically across facilities, so no single return address exists.
How to Measure Whether Amazon MCF Is Paying Off
Fulfillment decisions get made on assumptions and reviewed on invoices, which is backwards. Pick five numbers and check them on a schedule.
- Landed fulfillment cost per unit, by channel
- Discount capture rate against eligible units
- Peak variance versus your September baseline
- Dispatch and delivery rate against channel SLAs
- Days of supply by child ASIN
Weekly during peak and monthly the rest of the year is the right cadence. Pull actual fees from the Payments statement export in Seller Central, and confirm discounts in the Multichannel Fulfillment dashboard rather than trusting the rate card.
Frequently Asked Questions About Amazon MCF
Get Your Shopify and TikTok Fulfillment Right
Amazon MCF ships your Shopify and TikTok Shop orders out of the FBA stock you already own, which is why both channels look cheap until the invoice arrives. Size tier, delivery speed, units per order, and the October 15 peak window decide what each one actually costs.
Routing decides the rest. A TikTok Shop order attributed through a supported integration takes 35% off while the same order keyed in manually pays full price, and bulky SKUs belong with a 3PL no matter which channel sold them.
