You booked a shipment to an Amazon fulfilment centre, accepted the shipping estimate and sent your inventory. Later, you find an additional carrier charge in Seller Central. Before you dispute it, match the charge to the shipment and check what changed between booking and billing.
This checklist is for sellers reviewing inbound shipments sent through the Amazon Partnered Carrier program.
1. Match the charge to the shipment
Open the relevant transaction in Seller Central and note the charge date, amount and description. Then pull up the shipment and compare the FBA shipment ID, carrier and tracking number. For freight, use the bill of lading or other shipment reference if available. If the charge does not show a shipment ID, ask Seller Support to identify the shipment and explain the charge.
2. Compare the estimate with what you were billed
Put the original shipping estimate and the posted charges side by side. Check whether the new entry is a separate adjustment or the full shipping charge. Include any related credits when you calculate the difference. For example, if the original $120 charge remains posted and a separate $35 adjustment appears with no offsetting credit, the amount to investigate is $35.
3. Check the recorded weight and dimensions
Compare what you entered in Send to Amazon with your packing records and any carrier measurements available. For parcels, use the outside dimensions and weight of each packed carton. For freight, check the loaded pallet dimensions, total weight and freight class where applicable.
Amazon says a measurement difference can result in a charge or a credit for domestic US Partnered Carrier shipments. For partnered LTL or FTL shipments, Amazon also notes that actual charges can exceed the estimate if the carrier determines that the pallets are heavier than declared or the freight class is incorrect.

4. Gather evidence for the specific discrepancy
- The shipment ID, carrier, tracking number or freight reference.
- The original shipping estimate and a screenshot or export of the posted transaction.
- Packing records, scale readings or dated photos showing the labelled carton or pallet and its measurements, if available.
- Any carrier measurement notice, pickup paperwork or bill of lading that helps explain the difference.
A delivery receipt can help match paperwork to the shipment. If the dispute is about weight or size, include records that show those measurements.
5. Request a review through Seller Central
Give Seller Support the shipment ID, transaction date and amount. State exactly what differs and attach the records that support your request. If the reason for the adjustment is unclear, ask for a breakdown and the measurements or shipment details used to calculate it. If the records point to an error, request a review of the specific adjustment.
