What happened?
Amazon Seller Forums still featured extensive discussion of USPS shipping adjustments on September 14. Some sellers reported that shipping adjustment fees were added to past orders, with public examples showing additional charges of approximately $0.37 and $1.74 per shipment. Amazon’s official response advised sellers to verify the product dimensions, weight, and return address entered in Seller Central to avoid correction charges after carrier remeasurement. The source also noted that forum discussions do not mean Amazon has announced a new uniform rate, nor can they be used to infer that the platform has formally expanded the retrospective billing period or that all sellers will be charged. Sellers using Buy Shipping and USPS, offering low-priced lightweight products, or managing large volumes of historical orders may be more exposed. Sellers should download fee details, compare declared dimensions with carrier measurements on a shipment-by-shipment basis, and distinguish actual shipping-cost differences from system-generated adjustments.
What does this mean for cross-border sellers?
USPS shipping adjustments may raise fulfillment costs for sellers using Buy Shipping or USPS, particularly those selling low-priced lightweight products. Additional charges of approximately $0.37 and $1.74 have appeared on some orders. Verify dimensions, weight, return addresses, and fee details, but do not interpret forum discussions as confirmation of a new uniform Amazon rate or an expanded retrospective billing period.
