Let’s get to it!
AI-Generated Content Now Requires a Disclosure
In response to a New York state transparency law regulating "synthetic performers," Amazon is now requiring third-party sellers to tag any product photos, videos, or A+ Content featuring photorealistic, AI-generated people. To remain compliant, sellers must include specific metadata (such as the contains-synthetic-performer tag) in their media files prior to uploading them to Seller Central. Amazon will then display a visible disclosure on the product listing, informing consumers when an image or video utilizes synthetic human models rather than real human talent.
The catalyst for the requirement is New York's S.8420-A legislation, which penalizes undisclosed AI-generated human likenesses in commercial advertising shown to state residents with fines reaching up to $5,000 per violation. Because Amazon maintains a single uniform product catalog across the United States rather than customizing listing images by state, the policy effectively applies platform-wide. As a result, sellers who adopted AI-generated lifestyle models to reduce photography costs must now audit their product imagery to ensure compliance and avoid potential listing suppression or account suspension.
TL;DR Most seven-figure Amazon sellers lose margin and speed on the inbound half of the supply chain, between the supplier and the moment a unit becomes Prime-eligible. Eight levers control that stretch: inventory positioning, time to Prime, replenishment cycle length, placement fees, dock appointments, surge capacity, prep accuracy, and managed services.
Amazon Warehousing and Distribution (AWD) now only accepts inbound ASINs/units smaller than 18" x 14" x 8", and lighter than 20lbs. Box dimensions shouldn't exceed 25 inches on any side, and must be 50lbs or lighter. Anything exceeding these thresholds should be sent directly to the fulfillment network using the Send to Amazon workflow.
Amazon continues in their announcement to state that this change is to make these bulky and oversized items reach fulfillability faster, supporting faster delivery speeds to the customers.
Beginning September 30th 2026, Amazon will begin enforcing a new performance metric for FBM sellers. Keeping in line with their mission to be the world’s most customer-centric brand, Amazon is implementing a new benchmark for FBM sellers to ensure the on-time delivery of Amazon Business customer orders, minimizing re-delivery attempts.
All FBM Seller Business Hour Delivery Rates (BHDR) must be 90% or higher before October 30th. This is the measurement of seller fulfilled orders that were delivered within a business’s customer business hours. Failure to reach this benchmark will result in deactivation of offers for Amazon Business customers.
