The Amazon marketplace is evolving faster than ever. For sellers — whether you’re a solo entrepreneur running a small storefront or a multi-million-dollar brand — staying on top of Amazon marketplace policy news is no longer optional. It’s survival. From sweeping fee restructures and tightened compliance requirements to new AI-powered seller tools and the impact of global tariffs, 2025 and 2026 have brought a wave of changes that are reshaping how business gets done on the world’s largest e-commerce platform.
This article breaks down the most significant Amazon marketplace policy updates, what they mean for your business, and what you should be doing right now to stay ahead.
1. FBA Fee Changes: A Stable 2025 Followed by a 2026 Reset
One of the most closely watched areas of Amazon marketplace policy news is always the fee structure. In a move that surprised many sellers, Amazon kept U.S. referral and FBA fees unchanged throughout 2025 — a rare moment of financial stability on a platform known for annual increases.
However, that stability has given way to a modest reset for 2026. <cite index=”80-3,80-4″>In 2026, FBA fees will increase by an average of $0.08 per unit sold, or less than 0.5% of an average item’s selling price — on top of no increase in U.S. referral and FBA fees in 2025.</cite> Amazon has framed this as a minor adjustment, noting that <cite index=”80-6″>the fee changes are significantly less than inflation and less than the 3.9%–5.9% annual cost increases from other major U.S. carriers during the last two years.</cite>
While the increase may seem small on paper, the impact is not uniform. <cite index=”75-21″>The U.S. increases are minor on paper, but sellers absolutely need to re-model their margins — especially lower-priced goods where eight cents can erase already thin contribution margins.</cite>
Meanwhile, sellers operating in Europe are seeing a very different picture. <cite index=”75-10,75-11″>On December 2, 2025, Amazon announced one of its largest-ever fee reductions for European marketplaces. For 2026, Amazon will lower fees by an average of £0.15/€0.17 per unit sold across Europe, driven mainly by FBA and referral fee cuts.</cite> <cite index=”75-18″>For brands selling in both North America and Europe, this creates an interesting split: modestly higher costs in the U.S., but new savings opportunities in EU stores.</cite>
2. The New Policy Compliance Dashboard
One of the most operationally significant Amazon marketplace policy updates of 2025 was the overhaul of how sellers manage compliance documentation. <cite index=”61-1″>Beginning May 29, 2025, all product and food safety compliance details moved from the Manage Your Compliance dashboard to the new Policy Compliance section — a centralized hub designed to simplify regulatory management.</cite>
This new section consolidates product safety, food safety, and documentation status across an entire catalog in a single interface. For sellers managing large product catalogs or operating in regulated categories, this change is significant — it means all compliance flags, documentation requirements, and regulatory notices are now visible in one place, making it harder to miss critical issues before they escalate into listing suppression or account penalties.
3. Tightened Lab Compliance and Product Safety Standards
Amazon’s approach to product safety has shifted dramatically. <cite index=”64-1,64-2″>In July 2025, Amazon announced a sweeping update that directly impacts product testing across the marketplace. Compliance reports are now only accepted from labs that meet Amazon’s internal safety standards.</cite>
For sellers in the toys and children’s products categories, the stakes are even higher. <cite index=”63-6,63-7″>Amazon introduced a specific additional requirement for the toys and children’s products category from September 3, 2025. Sellers must now complete annual testing or documented verification through a compliant Testing, Inspection and Certification (TIC) provider on a recurring basis — not once at product launch.</cite>
The implications are clear: <cite index=”64-23,64-24,64-25″>for years, sellers often treated compliance as a checkbox exercise — submit a test report, clear the hurdle, and move on to the next launch. But Amazon’s new stance suggests that those days are over.</cite> <cite index=”64-26″>By placing more weight on the credibility of testing providers, Amazon is signaling that compliance is about trust and risk management, not just paperwork.</cite>
Sellers should immediately cross-reference their current testing providers against Amazon’s Suspended Validation Labs list inside the Service Provider Network in Seller Central. A rejected submission from a suspended lab counts as a non-submission on your Account Health record.
4. FBA Reimbursement Policy: A Major Shift in How Losses Are Calculated
Another significant piece of Amazon marketplace policy news that caught many sellers off guard was the change to FBA inventory reimbursements. <cite index=”68-5,68-6″>Amazon overhauled how it reimburses FBA sellers for lost or damaged inventory. Starting March 10, 2025, reimbursements for inventory lost before a customer order are based on manufacturing cost, not retail or sales price.</cite>
<cite index=”68-9,68-10″>Previously, Amazon’s reimbursements for warehouse losses often approached retail value. Now, unless you manually submit your actual manufacturing cost, Amazon will estimate it based on similar listings — which often means getting pennies on the dollar.</cite>
To protect your margins under this new policy, sellers should log into the Inventory Defect and Reimbursement Portal and manually enter true manufacturing costs for all high-volume or high-ticket ASINs. Leaving this to Amazon’s estimates is a costly mistake.
5. FBM Refund Policy Update: More Time, More Responsibility
Sellers who fulfill their own orders — known as Fulfilled by Merchant (FBM) — faced a notable policy change effective January 26, 2026. <cite index=”66-12,66-13,66-14″>The processing window for refunds extended from two business days to four calendar days before Automated Refund triggers. For most return delivery days, sellers gain additional processing time. However, if a refund is not processed within four calendar days of receiving a returned item, Amazon may issue an automatic refund.</cite>
For high-volume FBM sellers, this means having a documented return processing SLA assigned to warehouse or VA teams — with a built-in buffer to avoid triggering automatic refunds that could also affect SAFE-T claim eligibility.
6. Inventory Commingling Ends: A Win for Brand Integrity
A long-standing concern for brand-conscious sellers is finally being addressed. <cite index=”78-1″>Amazon will fully end inventory commingling by March 31, 2026, meaning sellers’ products will no longer be mixed with identical items from other sellers, significantly reducing counterfeit and safety risks.</cite> <cite index=”78-8″>For Amazon sellers, this increases buyer trust and brand protection, but resellers will now be required to use Amazon barcodes, adding labeling costs and operational changes for compliance.</cite>
7. Tariffs and Global Trade Pressures
No discussion of Amazon marketplace policy news in 2025 is complete without addressing the impact of tariffs. <cite index=”62-12,62-13,62-14″>The removal of the de minimis exemption for low-value imports from China in 2025 created new costs for sellers relying on low-value shipments. Sellers reported higher duties and slower clearance times, forcing many to reevaluate sourcing and pricing strategies. This policy change reshaped category-level margins and shifted competitiveness across multiple product lines.</cite>
<cite index=”73-21,73-22″>Tariff volatility threatens margin assumptions. Big macro moves can suddenly make a supplier unaffordable overnight.</cite> Sellers are advised to build tariff contingency plans with at least two alternate sourcing options for high-risk suppliers and to run sensitivity analyses at multiple tariff scenarios before finalizing pricing.
8. The Rise of AI in the Amazon Marketplace
Amazon’s investment in artificial intelligence is reshaping the seller experience from the inside out. New AI-powered tools are being integrated across Seller Central, Amazon Ads, and the customer-facing shopping experience. <cite index=”71-25,71-26″>An “Account Memory” feature introduced in late 2025 incorporates a shopper’s purchase history, Prime Video viewing, and Audible listening into recommendations. The “Help Me Decide” comparison feature launched in October 2025 means that listings with clear, specific differentiation perform better in head-to-head AI comparisons than listings relying on generic benefit statements.</cite>
For sellers, this signals that listing optimization is no longer just about keywords — it’s about content quality, specificity, and how well your product data feeds into Amazon’s AI systems.
9. Account Health: The Most Important Metric You Might Be Ignoring
Across all of these Amazon marketplace policy changes, one theme is constant: Account Health matters more than ever. <cite index=”61-25,61-26″>Amazon tightened its Account Health enforcement in 2025 by expanding its Account Health Rating and Account Health Assurance programs. The current system requires sellers to keep a score above 200 to stay healthy, while lower scores might lead to suspension.</cite>
<cite index=”61-2″>Building a monthly ritual around checking the Account Health page, resolving any policy flags, and documenting your processes is just as important as tracking ACoS or TACoS.</cite>
What Sellers Should Do Right Now
The pace of Amazon marketplace policy news shows no signs of slowing. Here is a concise action checklist for sellers:
- Re-model your margins with the 2026 FBA fee increases factored in, especially for lower-priced SKUs
- Audit your compliance labs against Amazon’s Suspended Validation Labs list
- Enter your manufacturing costs manually in the Inventory Defect and Reimbursement Portal
- Build a return processing SLA for FBM operations with a four-day buffer
- Explore European marketplace opportunities given the significant fee reductions in EU stores

<cite index=”62-26,62-27″>Amazon’s landscape continues to evolve at a rapid pace, from shifting compliance rules and fee updates to global tariff pressures and changing seller strategies. For entrepreneurs and brands, staying informed isn’t just useful — it’s essential for staying competitive.</cite> The sellers who treat every policy update as a planning opportunity — not a panic moment — are the ones who will come out ahead.
