Amazon's Inventory Rebalancing Fee and More: FBA Fee Hikes Reshape Seller Economics in 2026

Amazon's 2026 FBA Fee Storm: What Sellers Must Know

Amazon's new inventory rebalancing fee, rolled out on June 3, 2026, is forcing FBA sellers to rethink their distribution strategies. This per-unit surcharge of $0.08 to $0.27 applies when inventory is unevenly spread across Amazon's fulfillment network, directly penalizing sellers who rely on single-origin 3PL partners or skip split shipments. The fee is part of a broader wave of cost increases that collectively raise landed FBA costs by 11–17% for mid-size sellers, according to an analysis by Ecommerce Times.

What Is the New Amazon Inventory Rebalancing Fee?

The inventory rebalancing fee is a charge Amazon assesses when a seller's inventory is not optimally distributed across its fulfillment centers. The fee ranges from $0.08 to $0.27 per unit, depending on the item's size and the degree of imbalance. The stated goal is to encourage sellers to use Amazon's Split Shipment program, which distributes inventory to multiple receive locations, or to adopt Amazon's AWD (Amazon Warehousing and Distribution) service. In response, many mid-market sellers are pivoting to a "3PL buffer" strategy: holding bulk inventory at independent warehouses and replenishing Amazon fulfillment centers in smaller, more frequent batches. This approach avoids the rebalancing fee while maintaining Prime eligibility. Full details are available in this Ecommerce Times report.

Inventory Rebalancing Fee (June 2026)	Standard-Size	Oversize
Per-unit surcharge	$0.08 – $0.18	$0.12 – $0.27
Trigger	Uneven distribution across FCs	Same
Avoidance method	Use Split Shipment or AWD	Same

Inbound Placement Fee Expansion: Up to $1.58 per Unit

Six months after Amazon expanded its inbound placement fee structure, the financial impact is clear. Fees now range from $0.27 to $1.58 per unit depending on SKU characteristics, such as size, weight, and shipping method. Sellers who send shipments to a single Amazon receive location pay the highest fees, while those who split shipments to multiple locations pay significantly less. Amazon's AWD program also offers reduced fees for bulk distribution. The fee expansion, effective June 2, 2026, is detailed in this analysis by Ecommerce Times. Mid-size sellers are re-evaluating their supply chain: some are shifting volume to Fulfilled by Merchant (FBM) or third-party logistics providers to sidestep the fees entirely.

Overall Fee Impact: 11–17% Cost Surge for Mid-Size Sellers

Beyond the inventory rebalancing and inbound placement fees, Amazon has raised FBA fees three times in spring 2026. A 3.5% fuel and logistics surcharge and a change in payment holding (sellers now wait seven days after delivery for payouts) compound the increases. The cumulative effect: an 11–17% rise in the average landed FBA cost per unit for mid-size sellers, as reported by The Conveyor. With Prime Day 2026 scheduled for June 23–26, sellers are forced to offer less aggressive discounts to preserve margins. Inventory cutoff dates have already passed for many marketplaces, as discussed in Reddit’s AmazonFBA community.

The Alleged Seller Account Purge: Project Meridian?

Since mid-May 2026, Amazon has reportedly suspended or permanently banned an estimated 300 to 500 established seller accounts, many with long-standing positive performance. The bans come with minimal explanation, fueling speculation that a new AI-driven account review system—dubbed "Project Meridian"—is the culprit. The alleged purge is raising alarm among brand aggregators and individual sellers alike, particularly with Prime Day imminent. Affected sellers are scrambling to appeal while facing lengthy reinstatement times. Read more in this Ecommerce Times investigation.

Prime Day 2026: Strategies for Fee-Riddled Sellers

With Prime Day June 23–26, sellers face a tough balancing act. Inventory deadlines have passed for most, but alternative fulfillment options exist for latecomers. Sellers are discussing creative workarounds on forums and YouTube, such as using FBM for remaining inventory or running lightning deals off-Amazon. The FBA New Selection program is expanding benefits starting July 30, offering bigger incentives for new ASINs—a potential bright spot for post-Prime Day launches. Meanwhile, sellers are auditing their listings for agent-ready attributes to compete in AI-driven discovery, as outlined in this SellerSprite guide.

Conclusion

The 2026 fee landscape on Amazon is the most challenging in years. Between the inventory rebalancing fee, inbound placement hikes, and the alleged account purge, FBA sellers must be proactive. Adopting a 3PL buffer, splitting shipments, and diversifying fulfillment channels are no longer optional—they are survival tactics. With Prime Day days away, the sellers who adapt quickly will weather the storm.
