Amazon’s New Inbound Placement Fees Are Splitting FBA Sellers Into Two Camps

Fourteen months after Amazon quietly introduced inbound placement fees as part of its broader 2025 fee restructuring, the fallout is becoming clearer — and it’s dividing the FBA seller community into two distinct operating camps. Sellers moving high-velocity, standardized SKUs are largely absorbing the cost and holding position. Everyone else is recalculating.

The fee, which charges sellers anywhere from $0.21 to $0.89 per unit for single-location inbound shipments depending on size tier, was initially absorbed by many as a rounding error. By Q1 2026, with Amazon tightening its inbound split requirements and directing more inventory to four and five FC destinations rather than two, the line item has become material. Sellers running sub-35% net margins on mid-volume SKUs are now watching inbound placement eat 2 to 4 percentage points of margin they don’t have.

How significant are the new inbound fees on a per-unit basis?

The math varies sharply by product category and shipment volume. For a standard small-size item — think a $22 phone accessory or a $19 kitchen tool — the placement fee at the highest split tier runs roughly $0.27 per unit. That sounds manageable until a seller is shipping 8,000 units per month. At that volume, the fee adds approximately $25,900 in annual cost that didn’t exist in 2024.

Kiri Masters, founder of Bobsled Marketing and one of the more closely followed voices on Amazon fee policy, has been tracking the downstream impact with a handful of her agency’s clients since Q4 2025.

“We’ve modeled this across 23 active catalog clients and the average drag on net margin is 2.7 points for sellers doing under $500K monthly on Amazon. For those doing over $1M with broad SKU assortments, it’s actually closer to 1.4 points because they’re qualifying for the Partnered Carrier discounts more consistently. Scale is offering a real offset here.”

Masters’ team has started recommending that smaller FBA sellers actively pursue Amazon’s Partnered Carrier Program for all inbound shipments where possible — a move that can reduce the per-unit placement fee by 30 to 45% depending on the shipment origin and destination FC pairing.

Are sellers shifting back to FBM to escape the fee pressure?

Some are — but the move is more surgical than wholesale. Sellers aren’t abandoning FBA. They’re auditing their catalogs and pulling specific SKUs out of FBA when the placement fee math erodes the benefit of Prime eligibility below a defensible threshold.

Brandon Young, founder of Seller Systems and a frequent presence on the Amazon seller conference circuit, outlined the framework his team is applying to client catalogs in a private Slack group that was later shared with Ecommerce Times.

“The rule we’re using is: if your FBA net margin after all fees — storage, placement, referral, fulfillment — drops below 18% on a SKU, and that SKU isn’t in a category where Buy Box suppression is a real threat without Prime, you pull it to FBM and run Seller Fulfilled Prime if you can qualify. That’s the threshold where FBM wins on the math.”

Seller Fulfilled Prime re-qualification remains a bottleneck. Amazon’s SFP program requires a 99% on-time ship rate and a sub-0.5% cancellation rate, maintained over a 90-day trailing window. For sellers without robust 3PL relationships or in-house operations, the bar is difficult to hit consistently.

The sellers who are executing the FBA-to-FBM switch most cleanly are those with established relationships with regional 3PLs — companies like ShipMonk, Whiplash, or Stord — that can handle two-day ship commitments reliably enough to maintain SFP eligibility. The ones without those relationships are largely staying in FBA and cutting elsewhere.

What tactical adjustments are winning sellers making right now?

Beyond the FBA/FBM arbitrage, sellers who are managing the placement fee impact effectively are executing a cluster of specific operational changes:

• Consolidating SKU count: Sellers are discontinuing tail SKUs — products below $18 average selling price with less than 15 units per day velocity — where placement fees eliminate any margin buffer. Several multi-brand operators told Ecommerce Times they’ve cut catalog breadth by 20 to 30% since January 2026.
• Negotiating directly with prep centers: Sellers using Amazon-approved prep and inspection centers are renegotiating rates specifically to absorb a portion of the placement cost through higher-volume throughput commitments. One California-based prep center operator described receiving three such renegotiation requests in April alone.
• Shifting to palletized LTL inbound: For sellers doing 500+ units per SKU per shipment, palletized LTL through Amazon’s Partnered Carrier network is consistently delivering the lowest net placement fee. Sellers previously defaulting to small parcel UPS are switching in meaningful numbers.
• Using Inventory Placement Service selectively: Amazon’s opt-in Inventory Placement Service, which allows sellers to send all units to a single FC in exchange for a higher per-unit fee, is being used by some sellers during peak prep crunch periods as an operational simplicity trade-off — not a cost optimization.
• Running tighter reorder cadences: To reduce average unit exposure to aged inventory fees while managing placement costs, some sellers are cutting order quantities per shipment and increasing shipment frequency. The tradeoff is higher per-shipment inbound cost, but lower aged inventory risk on slower-moving SKUs.

How is the placement fee affecting Amazon PPC strategy?

The ripple effects into advertising are real. As placement fees compress margin, sellers have less room to absorb high ACoS (Advertising Cost of Sale) on defensive or growth campaigns. The practical result is that many mid-market sellers are tightening target ACoS thresholds — pulling back on top-of-funnel Sponsored Display and Sponsored Brand Video spend and doubling down on high-converting Sponsored Product exact-match campaigns against their own ASINs and direct competitor ASINs.

Ritu Java, CEO of PPC Ninja and a recognized figure in the Amazon advertising community, described the shift she’s observing across her client base of approximately 200 active Amazon sellers.

“The placement fee is functioning like a hidden COGS increase. When COGS goes up, rational sellers compress their TACoS targets. We’re seeing clients drop their blended TACoS targets by 2 to 3 points, which means campaigns that were previously acceptable are now getting paused. It’s making the auction less competitive in some niches — but it’s also meaning some sellers are conceding rank they held before Q1.”

Java noted that sellers with strong organic rank — typically those with 200-plus reviews, optimized A+ Content, and a high conversion rate relative to category benchmarks — are weathering the PPC compression better because they’re less dependent on paid traffic to maintain Buy Box share and page-one placement.

Is Walmart Marketplace picking up displaced FBA volume?

Anecdotally, yes — though the scale remains modest relative to Amazon’s overall FBA volume. Several multichannel operators who spoke with Ecommerce Times said they’ve accelerated Walmart WFS (Walmart Fulfillment Services) onboarding for SKUs they’ve pulled from FBA, specifically in categories where Walmart’s marketplace penetration is strong: home goods, pet supplies, and consumables.

Walmart Connect’s aggressive seller recruitment through Q1 2026 — including a reported waiver of WFS onboarding fees for sellers migrating from FBA with verified monthly GMV above $10,000 — has made the economics more attractive. WFS per-unit fulfillment fees remain approximately 8 to 12% lower than FBA equivalents in the standard-size tier as of May 2026, and Walmart has not implemented an equivalent to Amazon’s inbound placement fee structure.

The conversion caveat is traffic. Walmart Marketplace’s search traffic is roughly 14% of Amazon’s in the categories where FBA sellers are most concentrated, according to internal estimates shared by two agency operators. Sellers who migrate SKUs to WFS without actively building their Walmart PPC presence — particularly Walmart Sponsored Products — are finding that the fee savings are offset by lower sales velocity.

What should sellers do right now to protect margins?

The operators navigating this most effectively are treating the inbound placement fee not as a standalone problem but as a forcing function for a broader catalog and operations audit that was probably overdue anyway.

The practical checklist emerging from agency operators and experienced sellers in the community:

• Pull an ASIN-level profitability report using Sellerboard, Helium 10 Profits, or a custom Seller Central data export, and layer in actual placement fees incurred in the last 60 days per ASIN.
• Identify any ASIN where placement fees plus FBA fulfillment fees plus referral fee exceeds 45% of the selling price. Those are your highest-risk SKUs.
• Evaluate SFP eligibility for your business. If you’re shipping 200+ orders per day from your own warehouse or a qualifying 3PL, SFP is worth pursuing aggressively in 2026.
• For catalog SKUs below $15 ASP, run the math on whether Amazon remains the right primary channel. Walmart, eBay, and direct-to-consumer channels may deliver better unit economics for low-ASP products where Amazon’s fee stack is most punishing.
• If you’re shipping inbound via small parcel, get a freight quote for palletized LTL through Amazon Partnered Carrier. For many sellers, this is a simple operational change that reduces placement fees materially within 60 days.

The fundamental tension is unlikely to resolve soon. Amazon has structural incentives to push sellers toward multi-FC inbound distribution — it reduces its own fulfillment cost and improves Prime delivery speed — and the placement fee is the mechanism. Sellers who build operations around that reality will absorb less friction than those who keep treating it as a temporary anomaly.
