Amazon quietly updated its Multi-Channel Fulfillment (MCF) rate card on June 15, rolling out cost increases averaging 12–18% on standard-size units and a steeper 22% on oversized items — changes that took effect July 1, 2026. For the tens of thousands of sellers who rely on MCF to fulfill Shopify, Walmart, and TikTok Shop orders out of Amazon’s warehouses, the math on that hybrid strategy just got significantly harder.
The increases follow Amazon’s FBA storage fee overhaul announced in February, compounding pressure on sellers who had already restructured their inventory posture for H2. What’s different this time is that the MCF hike directly taxes the off-Amazon revenue stream many sellers had been quietly building as a hedge against marketplace fee exposure.
What Exactly Changed in Amazon’s MCF Rate Card?
The revised MCF fee schedule, published in Seller Central under the Fulfillment by Amazon fee schedule update, reflects increases across nearly every weight tier. A standard-size item weighing 1 lb now costs $5.38 to fulfill via MCF, up from $4.61 in Q1 2026 — a jump of $0.77 per unit. On a SKU moving 3,000 units per month off-Amazon, that’s roughly $2,300 in additional monthly cost at a single weight tier.
- Standard-size units (up to 1 lb): up 16.7%, from $4.61 to $5.38
- Standard-size units (1–2 lb): up 14.2%, from $5.09 to $5.81
- Large standard units (2–3 lb): up 18.4%, from $6.10 to $7.22
- Oversized small (up to 70 lb): up 22.1%, from $9.73 to $11.88
- Two-day MCF delivery surcharge: introduced at $1.25 per unit for non-Prime destinations
Amazon has framed the changes as a reflection of carrier cost normalization and increased handling complexity in its fulfillment centers. But sellers are skeptical. “They’re essentially taxing you for the audacity of selling somewhere other than Amazon,” said Kiri Masters, founder of Bobsled Marketing and a longtime Amazon channel strategist. “MCF was always a convenience play, not a cost-optimization play — but now the convenience premium has gotten hard to justify.”
Which Sellers Are Most Exposed to This Fee Increase?
The sellers most vulnerable to the MCF hike fall into two camps. The first is the classic “Amazon-first” brand that built its 3PL strategy entirely around FBA, using MCF as a lazy extension for DTC and Walmart orders rather than investing in an independent fulfillment infrastructure. The second is the mid-market seller running 500–2,000 orders per day across channels, where the per-unit delta compounds fast enough to blow a quarterly P&L.
“We were running about 40% of our Shopify volume through MCF because the SLA consistency was hard to match elsewhere. Now we’re running the numbers and the blended cost is just not competitive anymore. We’re moving that volume to ShipBob’s Chicago node starting August 1.” — Jake Rheingold, founder, Apex Home Goods, $14M annual revenue seller
Sellers in the home goods, pet supplies, and sporting goods categories — all high-volume, moderate-weight SKUs — appear to be the most exposed based on the weight tier structure of the new rate card. Beauty and personal care sellers are somewhat insulated due to lighter unit weights, though the new two-day surcharge is creating friction for brands that had been using MCF’s two-day SLA as a competitive differentiator on their Shopify storefronts.
Are 3PL Providers Seeing an Immediate Influx of Displaced MCF Volume?
According to multiple operators, the answer is yes — and the pipeline is moving faster than typical 3PL sales cycles. ShipBob, which operates over 40 fulfillment nodes across the U.S. and Europe, confirmed to Ecommerce Times that it has seen a material uptick in inbound inquiries from Amazon sellers since the MCF rate announcement dropped. Flexport’s fulfillment division and Whiplash have reported similar dynamics.
ShipBob’s standard pricing for a 1 lb standard-size unit pick-and-pack fulfillment currently runs approximately $3.90–$4.40 depending on storage tier and volume commitment — meaningfully below the revised MCF rate even before accounting for ShipBob’s negotiated carrier rates with UPS, FedEx, and USPS. For sellers shipping primarily to domestic addresses, the math increasingly favors a dedicated 3PL relationship.
“We’re onboarding sellers in seven to ten days right now for merchants who were MCF-dependent. The fee change created an urgency that we haven’t seen since the 2022 FBA surcharge cycle. Sellers are moving fast.” — Dhruvil Sanghvi, CEO, LogiNext, speaking at a fulfillment operations roundtable in Chicago last week
The migration isn’t frictionless. Sellers moving off MCF need to either ship inventory to a new 3PL network or manage a split-inventory model where Amazon FBA handles marketplace orders and a third-party 3PL handles everything else. That split model adds operational complexity — separate inbound shipments, separate inventory tracking systems, and the need for a middleware layer like Linnworks, Skubana (now Extensiv), or Pipe17 to keep oversell risk manageable.
How Does This Change the FBA vs. FBM Calculus for Multi-Channel Sellers?
The MCF hike is accelerating a strategic realignment that was already underway. Increasingly, sophisticated Amazon sellers are treating FBA purely as an Amazon marketplace tool — leveraging it for Buy Box eligibility, Prime badge access, and the SLA guarantees that drive conversion on Amazon.com — while building independent fulfillment infrastructure for all off-Amazon channels.
That model requires more upfront capital and operational overhead, but it insulates brands from Amazon’s continued fee increases and gives them more carrier flexibility. Sellers running Walmart Marketplace orders through MCF face an additional complication: Walmart’s Seller Fulfilled Prime equivalent, the Walmart Fulfillment Services (WFS) program, has improved its SLA reliability significantly in 2026, making WFS-to-WFS a cleaner option for Walmart-native volume.
- FBA remains optimal for Amazon.com marketplace orders where Prime eligibility drives Buy Box share
- MCF is now questionable for Shopify and DTC orders unless SKU weight is under 8 oz
- WFS is increasingly competitive for Walmart Marketplace orders, with standard fees running 8–15% below comparable MCF rates
- Independent 3PLs (ShipBob, Whiplash, Flexport) offer the most flexibility for true multi-channel operations
- FBM with your own 3PL is gaining renewed interest among sellers who want to reduce Amazon fee exposure entirely
“The sellers who are winning right now have completely decoupled their Amazon fulfillment strategy from their DTC fulfillment strategy,” said Destaney Wishon, CEO of BetterAMS and a prominent Amazon PPC strategist. “MCF was a crutch. The fee increase is forcing that discipline.”
What Should Sellers Do Before the August Inventory Cycle?
Operators who spoke with Ecommerce Times recommended a four-step triage process for sellers evaluating their MCF exposure heading into Q3:
- Run a unit economics audit by channel: Pull your MCF volume by SKU and weight tier from the last 90 days. Apply the new rate card and calculate the incremental monthly cost. Any SKU where MCF adds more than $1.50 per unit versus a 3PL alternative is a candidate for migration.
- Get 3PL bids immediately: ShipBob, Whiplash, Deliverr (now part of Flexport), and regional operators like Saltbox and Stord are all actively quoting MCF migrants. Expect standard onboarding timelines of 10–21 days depending on inventory complexity.
- Audit your inventory middleware: If you’re splitting inventory between FBA and a 3PL, you need a reliable order routing and inventory sync layer. Extensiv, Pipe17, and Linnworks are the most commonly deployed solutions for sellers in the $5M–$50M revenue range.
- Don’t touch your FBA inventory for Amazon.com orders: The Prime badge and Buy Box implications of pulling out of FBA entirely are severe. The play is surgical — keep FBA for marketplace orders, move off-Amazon volume to an independent 3PL.
“Sellers are panicking and making the mistake of pulling inventory out of FBA entirely. That’s wrong. You want FBA for the Amazon channel. You want a 3PL for everything else. Those are two different jobs.” — Kiri Masters, founder, Bobsled Marketing
Is This Fee Increase a Sign of Amazon Deprioritizing MCF?
Some operators believe the MCF fee hike is part of a deliberate Amazon strategy to push sellers toward keeping their entire fulfillment operation — including off-Amazon channels — inside the Amazon ecosystem through Amazon Buy with Prime. Buy with Prime, which allows merchants to embed Prime-badged checkout on their own DTC sites while fulfilling through Amazon’s network, has seen aggressive merchant adoption pushes throughout 2025 and 2026.
By making standalone MCF more expensive, Amazon may be nudging sellers toward Buy with Prime, which carries its own fee structure but bundles payment processing, fulfillment, and returns handling in a way that competes more directly with Shopify’s native checkout. For sellers already on Buy with Prime, the MCF rate increase is largely irrelevant — their DTC fulfillment is already running through Amazon’s infrastructure under a different fee arrangement.
Whether that’s intentional product strategy or simply cost-reflective pricing, the practical outcome is the same: multi-channel sellers now face a more complex fulfillment decision tree than they did 60 days ago, and the right answer varies meaningfully by SKU weight, channel mix, and order volume. The sellers who run that analysis before Q4 inventory commitments lock in will be better positioned than those who don’t.
