Amazon MCF in 2026: how it works, what it costs, and the 35% TikTok Shop discount

A practical guide to Amazon Multi-Channel Fulfillment for sellers running more than one sales channel, including how to qualify for Amazon’s 35% discount on US TikTok Shop orders.

What is Amazon MCF?

Amazon Multi-Channel Fulfillment (MCF) is a service that ships orders from your other sales channels using inventory stored in Amazon’s fulfillment centers. You send stock to Amazon once, and Amazon picks, packs, and ships each order no matter where the customer bought it: TikTok Shop, Shopify, eBay, your own website, or a wholesale account.

An MCF order is simply an order placed somewhere other than Amazon that Amazon fulfills. It draws from the same FBA inventory as your Amazon orders and ships through the same network that handles Amazon’s own volume.

For sellers already using FBA, that means one pool of inventory can serve every channel, instead of splitting stock across Amazon and a separate warehouse or 3PL.

How Amazon MCF works

Every MCF order follows the same four steps:

Amazon’s own data suggests sharing inventory this way pays off beyond convenience:

The 35% Amazon MCF discount for TikTok Shop orders

Starting July 16, 2026, Amazon is taking 35% off standard and expedited MCF fees for TikTok Shop orders shipped to US addresses. Here’s how it works:

The attribution requirement is the part to plan around. The discount only applies if each order reaches MCF with TikTok Shop recorded as its source, which in practice means routing orders through a supported integration rather than copying them over by hand. The setup in Base is covered below.

To check what you’re saving, open the Multichannel Fulfillment dashboard in Seller Central. Its TikTok Shop Discount benefits table shows the discount amount and number of discounted units by order. The data can lag by 24 to 48 hours.

Amazon MCF fees

MCF has no subscription. You pay a per-unit fulfillment fee on each order, based on four things:

Inventory you hold for MCF is the same inventory you hold for FBA, so it’s charged the normal FBA monthly storage fees. There’s no separate storage charge for MCF.

Non-peak rates from Amazon’s MCF rate card as of June 1, 2026. TikTok Shop columns show 35% off the listed rate, rounded. Amazon applies the discount to the fees in effect when an order ships, so during holiday peak season (mid-October to mid-January) it comes off the higher peak rates. Figures don’t include the 3.5% fuel and logistics surcharge Amazon adds to MCF fees. Orders with more than one unit cost less per unit. Check Amazon’s current rate card before modeling your own catalog.

Delivery speed and tracking

Amazon offers two MCF delivery speeds: standard, which delivers within 3 business days of the order, and expedited, within 2 business days. You choose the speed per order, or set a default through your integration. If you sell on your own website, MCF with Prime lets you show Prime delivery to Prime members at the same price as standard.

Speed matters most on TikTok Shop, which requires orders to be dispatched within two business days and delivered within six business days of entering Awaiting Shipment. Amazon reports that 96% of MCF orders are dispatched and 99% are delivered within those timelines.

When Amazon ships an MCF order, it creates a tracking number. If the order came in through an integration, that tracking number is passed back to the original channel so the customer can follow it there. You can also look up any MCF order in Seller Central.

Amazon also offers unbranded packaging for MCF orders, which matters for channels where Amazon-branded boxes would confuse customers or break marketplace rules.

Which channels you can use MCF for

MCF works with most channels, but each has its own rules on packaging, carriers, and delivery times. Check these before you route orders:

Amazon MCF vs. Walmart MCS, Fulfilled by TikTok, and 3PLs

MCF isn’t the only way to fulfill orders from more than one channel. The right choice mostly depends on where your inventory already sits.

Walmart is also running an introductory offer on Multichannel Solutions: sellers trying MCS for the first time get 20% off fulfillment fees for 90 days after their first order. The offer ends January 31, 2027. We covered it in our Walmart Let’s Grow 2026 recap. Plenty of sellers run two of these side by side, for example MCF for TikTok Shop orders and a 3PL for their own store.

When MCF makes sense, and when it doesn’t

MCF works best when most of your volume is already on Amazon. The stock is already in FBA, so your smaller channels can draw from it without a second warehouse. You avoid splitting inventory, and you avoid the stockouts that come with it.

It gets harder as your other channels grow. MCF fees are generally higher per unit than FBA fees for the same item, so the cost adds up at volume. And because every channel shares one pool of FBA inventory, a stockout on Amazon becomes a stockout everywhere.

At that point, many sellers split inventory between FBA and a second option, and route each order to whichever location makes sense. That only works if every channel’s orders and stock levels are visible in one place, which is where most multichannel and omnichannel operations run into trouble.

Routing TikTok Shop orders to Amazon MCF with Base

TikTok Shop and Amazon MCF are both integrated in Base, so connecting them is a setting rather than a build. In Workflow Automation you pick the event (a new order), the condition (source is TikTok Shop, destination is a US address), and the action (fulfill through Amazon MCF). Save it once, and every matching order routes itself with its TikTok Shop attribution intact, so eligible orders get the 35% discount.

The same approach works for any channel. You can send Shopify or eBay orders to MCF with a different rule, or route orders to MCF only when your own warehouse is out of stock. Three things make this work:
