Amazon Sellers Hit with New Fees, Lawsuits, and Insurance Rules in 2026

The life of an Amazon seller has never been simple, but the fourth quarter of 2026 is shaping up to be especially tumultuous. Between new cancellation penalties timed for the festive season, a bombshell lawsuit over a secret ad-pricing mechanism, a looming insurance mandate for thousands of sellers, and state-level antitrust actions, the landscape for third-party merchants is shifting rapidly. Here is what every Amazon seller needs to know about the major developments rocking the platform.

What Are the New Cancellation Fees on Amazon and Flipkart?

Amazon has introduced a cancellation fee of up to 10% of the order value for sellers, effective ahead of the 2026 festive season. The fee applies when a seller cancels an order after it has been placed, regardless of the reason. The penalty is calculated as a percentage of the item’s price, with a maximum cap that varies by category. This marks a significant shift from earlier policies where cancellation penalties were either flat fees or nonexistent in many cases.

According to TechShots, sellers are upset because the fee structure eats directly into already thin profit margins, especially during high-volume sales events when cancellations may spike due to inventory or logistics issues. Small and medium-sized businesses are the most vulnerable, as they lack the buffer to absorb a 10% loss on an order they could not fulfill.

Flipkart, Amazon’s main rival in India, implemented a three-tier penalty system at the same time. The table below compares the two structures.

Feature	Amazon (India)	Flipkart
Fee structure	Percentage of order value (up to 10%)	Three-tier flat fee based on order value bracket
Effective date	September 2026 (festive season)	September 2026
Seller concern	High percentage hurts margins unpredictably	Tiers may be less punitive for high-value orders but still significant
Small business impact	Severe – no minimum exemption	Moderate – low-value orders see lower absolute fees

Both platforms framed the changes as efforts to reduce frivolous cancellations and improve customer trust, but the timing – right before Diwali and Christmas — has many sellers feeling squeezed.

How Did Amazon’s Hidden Ad Surcharge Allegedly Cost Sellers Billions?

A federal lawsuit filed by the FTC and 22 states alleges that Amazon quietly introduced a “soft reserve price” into its advertising auctions in 2019, effectively creating a phantom bidder to push up costs. According to an analysis by PrimoInteractive, this hidden surcharge added tens of billions of dollars to sellers’ advertising bills over seven years. The lawsuit contends that Amazon never disclosed this mechanism to advertisers, violating competition laws.

Amazon’s advertising business has grown to become a major profit center, largely paid for by third-party sellers who rely on sponsored product ads to gain visibility. Sellers have long complained that ad costs are opaque and rising, but this lawsuit provides an accounting of the alleged tactic: Amazon’s system would set a reserve price — below which no winning bid could fall — and then bid on behalf of a fictional participant to ensure the advertiser paid more. The result, the FTC argues, is a platform that manipulates its own marketplace to extract more from sellers.

For sellers, the implications are twofold. First, if the lawsuit succeeds, they might receive refunds for overcharges — though any payout could take years. Second, the revelation has already triggered a backlash: in April 2026, CNBC reported that sellers boycotted Amazon ads to protest policy changes and payment structures. The hidden surcharge saga adds fuel to that fire and may lead to more advertiser pushback.

What Does the New $1 Million Insurance Requirement Mean for Amazon Sellers?

Starting November 2, 2026, Amazon will require third-party sellers of products in “enhanced safety categories” to carry $1 million in commercial general liability insurance, regardless of their sales volume. The policy was announced earlier but is now approaching its effective date. According to PPC.Land, affected categories include children’s products, cosmetics, ingestibles (vitamins, supplements, food items), and products containing lithium batteries.

Previously, Amazon only required insurance for sellers exceeding $10,000 in monthly sales. The new rule eliminates that threshold, meaning even a brand-new seller listing a single lipstick or baby toy must obtain a policy. Additionally, sellers based in Mainland China are required to purchase insurance exclusively through Amazon’s Insurance Accelerator program, which may limit options and increase costs.

This mandate creates a significant barrier to entry for small entrepreneurs. A $1 million policy can cost anywhere from $500 to $2,000 per year depending on risk category and location. For sellers already operating on thin margins, this is another fixed cost that must be absorbed. The change also imposes recordkeeping and policy-listing requirements, adding administrative burden.

Why Are California and Other States Suing Amazon Over Seller Pricing?

California Attorney General Rob Bonta filed an antitrust lawsuit alleging that Amazon uses its market power to coerce third-party sellers into not offering lower prices on other platforms. As reported by Noah News, the lawsuit claims Amazon penalizes sellers — through reduced product visibility, suppressed rankings, or account suspension — if they list items cheaper elsewhere. The practice effectively forces sellers to maintain price parity with Amazon, stifling competition from other ecommerce sites.

California is not alone. The Guardian covered leaked emails that show internal communications where Amazon executives discuss raising seller fees, which in turn force sellers to raise prices on all platforms. The state argues that Amazon’s policies function as an illegal price-fixing scheme that harms consumers and small businesses.

For sellers, this lawsuit — alongside the FTC ad case — could reshape how Amazon operates. If courts impose restrictions on Amazon’s ability to enforce price parity, sellers could finally list products for lower prices on other marketplaces or their own websites, increasing margins and reducing dependency on Amazon traffic.

How Is Amazon Responding to AI Agents Like Meta’s Muse?

Amazon has formally asked Meta to remove the retailer from its new Muse AI agent experience, an AI tool that can make purchases on behalf of users. According to Retail Dive, Amazon stated it was not given advance notice or authorization to be included in Muse. The company emphasized that third-party applications making purchases on its platform should operate openly and respect service providers’ decisions about participation.

This development matters to sellers because it signals Amazon’s position on AI-mediated commerce. If Amazon restricts or regulates how AI agents interact with its infrastructure, sellers may need to consider how their listings and advertising strategies adapt to an AI-driven purchasing environment. The broader trend — AI shopping agents like Music AI, ChatGPT’s browsing mode, or Perplexity’s shopping features — could reshape traffic sources and buyer behavior. Sellers should monitor Amazon’s evolving API policies and terms of service regarding automated access.

What Is the Shadow Bribery Market Inside Amazon?

A rare investigative report by Bloomberg, the Los Angeles Times, and the Mercury News revealed a shadow market where sellers bribe Amazon employees for favorable treatment. The Los Angeles Times detailed how middlemen offer access to Amazon insiders who can reinstate suspended accounts, remove negative reviews, or boost product rankings. The bribes range from hundreds to tens of thousands of dollars.

The investigation highlights a systemic problem: desperate sellers, particularly those from overseas, are vulnerable to exploitation because Amazon’s internal appeals process is opaque and slow. While Amazon has publicly condemned the practice and claims to have fired involved employees, the report suggests the problem persists. For honest sellers, this creates an uneven playing field and underscores the need for more transparent dispute resolution mechanisms.

What Is the Fuel Surcharge Amazon Is Applying to Sellers?

Amazon announced a 3.5% fuel and inflation surcharge on fulfillment fees for third-party sellers, reported by the Wall Street Journal. The surcharge, applied to Fulfillment by Amazon (FBA) fees, is meant to offset rising transportation costs. For sellers who use FBA, this adds another percentage point to already rising logistics expenses. The surcharge came into effect earlier in 2026 and remains in place.

Sellers have responded by diversifying fulfillment strategies — using their own warehouses, third-party logistics providers, or Amazon’s Buy Shipping with their own rates. The surcharge, combined with the other fee increases, is accelerating a trend toward multi-channel fulfillment.

How Are Amazon’s AI Image Policies Affecting Sellers?

Amazon has cracked down on the use of AI-generated images by sellers following a New York state law requiring transparency. As CNBC reported, Amazon now mandates that sellers label product images containing AI-generated depictions of people. The policy applies to lifestyle and model shots, but not standard product-only photos.

This affects sellers who use AI tools for product photography — a growing trend. Platforms like Loomadesign.ai offer AI-powered product photography suites specifically designed for Amazon sellers, creating realistic images without expensive photo shoots. Sellers using such tools must now ensure compliance with labeling requirements, especially for apparel, beauty, and children’s products that commonly use human models.

What Does the Reversal of Amazon’s Seller Partner API Monetization Mean?

Amazon rolled back its planned monetization of the Selling Partner APIs after seller backlash, according to Fivetran. The company had intended to charge for API access, but reversed course due to community pressure. The reversal was seen as a win for sellers and third-party developers who rely on free API access for inventory management, order processing, and analytics. The Fivetran blog notes that maintaining open APIs is critical for seller ecosystem health.

This episode demonstrates that collective seller action — including boycotts and public criticism — can influence Amazon’s decisions. It also highlights the ongoing tension between Amazon’s desire to monetize every part of its ecosystem and the need to keep sellers competitive.

Conclusion: A Pivotal Moment for Amazon Sellers

Amazon’s third-party marketplace has grown into a complex ecosystem where policy changes can make or break businesses. The developments of 2026 — cancellation fees, hidden ad charges, insurance mandates, antitrust lawsuits, AI regulation, and bribery scandals — represent a convergence of financial, legal, and operational pressures. Sellers who stay informed and adapt quickly will be best positioned to survive and thrive.

The key takeaway is that Amazon is facing unprecedented scrutiny from regulators and sellers alike. The outcomes of the FTC ad lawsuit, California antitrust case, and other legal challenges could reshape the platform for years to come. In the meantime, sellers should audit their costs, diversify their sales channels, and ensure compliance with the new insurance and image-labeling requirements.
