Hello,
To improve the accuracy of weight and dimension inputs for domestic US Amazon Partnered Carrier shipments, notifications in Seller Central inform you when carriers find differences between the measurements that you enter and your shipment's actual measurements.
If the measured weight, dimensions, or freight class (when applicable) of your small parcel or less-than-truckload shipment differs from what you provided at shipment creation, you see a notification in the Inbound Performance dashboard.
Starting on June 12, 2025, these measurement differences will result in a fee adjustment including a credit to your account if your provided measurements were too high or a charge if they were too low.
You can view your measurement differences by following these steps:
Go to the Inbound Performance dashboard.
Select Inaccurate transportation weight/dims under Defect group.
Click View details to see the specific measurement difference.
For more information, go to Amazon Partnered Carrier program FAQ.
