The FBA Fee Changes page helps you identify cases where Amazon has changed the FBA fee charged for a product and may have overcharged you as a result.
Fee changes often occur when Amazon updates a product’s dimensions or weight. In some cases, these changes are incorrect and lead to higher fulfillment fees than justified. sellerboard highlights such cases so you can review them and request reimbursement when appropriate.
Use this page to:
- Detect unexpected FBA fee increases
- Identify affected ASINs and orders
- Estimate potential overcharges
- Prepare structured reimbursement requests for Amazon
What the FBA Fee Changes page shows
sellerboard continuously monitors the FBA fees applied to your products.
When a new or different FBA fee is detected for an ASIN in a newer order, that order is flagged and listed on this page.
For each case, sellerboard shows:
- The previously charged fee
- The newly applied fee
- The difference between them
- The estimated overcharged amount
At the top of the page, you’ll see an Estimated reimbursement amount, representing the approximate total value of all flagged cases.
This amount is an estimate only. Amazon may reimburse a different amount or reject a claim based on their review.
Data range and date selection
The FBA Fee Changes report supports analysis for up to 18 months.
How do I select a date range?
- Use the date picker at the top of the page.
- Choose a start and end date (up to 18 months total).
- Apply the range to refresh the data.
sellerboard does not provide data older than 18 months in this section. For earlier periods, Amazon’s historical records must be reviewed directly.
Reviewing fee change cases
Not every fee change is incorrect.
Before contacting Seller Support, you should:
- Review the affected ASINs
- Check whether the new fee aligns with known changes in size, weight, or packaging
- Focus on clear discrepancies where the increase appears unjustified
Manual review helps avoid unnecessary or rejected support cases.

Contacting Amazon Seller Support
sellerboard does not contact Amazon on your behalf.
You must submit reimbursement requests manually in Seller Central.
Recommended support category
In Seller Central, open a case under:
Fulfillment by Amazon → Investigate other FBA issue → Confirm / Request reimbursement for product weights and dimensions
This category is specifically intended for FBA fee disputes related to measurements.
Using the support message template
sellerboard provides a pre-written message template to help you communicate clearly with Amazon.
How do I access the template?
- Scroll to the Contact Seller Support section on the page.
- Click Show template.
- Copy the message and paste it into your support case.
You can adjust the wording if needed, but the template already includes the essential structure Amazon expects.
Best practices for submitting fee change cases
To improve resolution chances:
- Open one support case at a time
- Attach the downloaded sellerboard report
- Include ASINs, order IDs, and fee details
- Politely request re-measurement or clarification
Submitting many cases at once can slow responses or lead to rejections.
If Amazon rejects the request
If your reimbursement request is rejected:
- Review Amazon’s response carefully
- Clarify the suspected weight or dimension discrepancy
- Provide additional evidence where possible (for example, measurements or packaging details)
- Resubmit the case with clearer references
Rejections do not always mean the fee change is correct, but they do require stronger documentation.
