When an FBA fee jumps because Amazon recorded larger dimensions or weight, compare the Fee Preview row with the packaged unit you actually send. Record length, width, height, and weight using the same packaged configuration, calculate the fee difference under the current rate card, and submit a remeasure request with clear measurement photos.
A fee-tier change can come from a real packaging change, a measurement error, or a new rate card. The audit needs to separate those causes. A product dimension taken without retail packaging is not comparable with Amazon's packaged measurement, and an old fee table cannot prove a current overcharge.
What the record changes
The discrepancy table should show Amazon's recorded dimensions, the seller's measured dimensions, the method and date of measurement, and the per-unit fee under the same current schedule. Photographs should show the whole package, each measuring edge, and the scale display. The request asks Amazon to remeasure. It does not promise which result Amazon will record.
- Seller Central contains a recurring set of threads titled around FBA fee overcharges and incorrect dimensions, which is direct evidence of the same report-level discrepancy.
- Fee Preview data and the seller's own packaged-unit measurements are sufficient to build a precise remeasure request without account access.
- The delivered audit uses the rate table in force on its delivery date and flags any measurement or packaging detail that cannot be confirmed.
How to use this answer
A reimbursement check compares events in the Inventory Ledger, Reimbursements, Returns, and Fee Preview exports. The same unit or fee can appear in more than one report, so the reports have to be reconciled before a claim is counted. Each surviving line receives a claim type, value at Amazon's policy basis, current window state, case wording, and a reference to the policy version used.
- Export fresh reports from Seller Central and keep the marketplace and report date with each file.
- Match inventory, return, reimbursement, and fee events before treating any single row as an open claim.
- File the oldest open lines first, but leave out rows that are too early, already reimbursed, expired, or unsupported.
Where the service stops
You download the reports and file every case yourself. Reality Contact, LLC never logs into Seller Central, keeps credentials, files a case, or contacts Amazon for you. A listed event only appears claimable under the policy version cited on the delivery date. Amazon decides whether it pays. This is not legal advice, tax advice, or accounting advice.
