Hi @Seller_EAhfGnOpWHr1b

Christine here from Amazon Forums.

First, you'll need to gather comprehensive documentation. This includes clear photos of the packaged item being measured with a tape measure or ruler visible in the image, photos showing the package on a calibrated scale, a copy of your original BOL (Bill of Lading), any relevant shipping manifest documentation, and NMFC freight classification documentation if applicable.

For your first appeal, navigate to Seller Central, go to Performance, then Shipping Performance. Locate the specific shipment in question and click "Dispute Charge." You'll need to upload all documentation mentioned above and provide a detailed explanation in the comments section.

If your first appeal is denied, open a case with Seller Support. Select "FBA Issues" then "Transportation." Make sure to include the case number from your first appeal, upload all documentation again, and specifically request escalation to the Transportation Team.

Some crucial points to remember: Always ensure your measurements include packaging materials, and document weight and dimensions BEFORE shipping. Take photos of pallets or cartons from multiple angles, maintain records of all carrier documentation, and include any relevant NMFC codes and documentation.

While carriers do have significant authority in determining final measurements, they must provide evidence of their measurements if challenged. If you haven't received this documentation, request it through Seller Support.

Remember to maintain detailed records of all communications and disputes for future reference. If you continue to experience similar issues with specific carriers, please alert us so we can investigate potential systematic problems.

Christine.
