I am reaching out to the Amazon seller community for help regarding a serious FBA misclassification issue that has resulted in significant overcharges on my FBA fees for several months. Despite multiple requests to Seller Support and irrefutable evidence, I have yet to receive any resolution. Here’s the situation:

Amazon misclassified my two ASINs (B0D2YF2GHB & B0D2YFV7PC) because their dimensions were miscalculated.This error overestimated my total inventory volume by more than 40%, directly increasing my storage and FBA inbound fees.

As a result, Amazon wrongly classified my products as "Large Bulky Parcels" instead of "Large Standard-Size". This misclassification led to an overcharge of $6,131 in FBA Inbound Fees, as Amazon applied the incorrect fee bracket. Due to this excessive charge, my account has been suspended multiple times, directly affecting:

Sales (no transactions could take place while the account was blocked).

Marketing efforts, as the negative balance prevented me from using MCF (Multi-Channel Fulfillment) marketing tools.

Despite multiple escalations, submitting official product dimensions, and providing Die lines that show the exact product sizes, no correction has been made. Even worse, despite undeniable evidence proving a clear mistake, Amazon insists that everything is correct, refusing to acknowledge or fix the issue. We have opened multiple cases with Seller Support, all of which have been unsuccessful. We also contacted our Account Manager, who confirmed that he would escalate the issue nearly a month ago, yet nothing has changed.Meanwhile, this situation is causing undeniable damage to my brand and generating excessive costs due solely to Amazon’s error.

This situation is counterproductive, as it not only causes significant financial losses for my brand but also seriously damages the Amazon Seller experience.Additionally, Amazon risks losing a seller who could generate far more revenue for them in the long run than the "small amount" they need to refund today. This inefficient handling of a clear mistake raises serious concerns about the reliability and fairness of the FBA program for serious sellers looking to invest and grow on the platform.

What I Need Help With:

Has anyone experienced a similar ASIN misclassification and FBA overcharge issue?

What escalation methods have you used to get a resolution when Seller Support was unresponsive?

Are there any direct Amazon contacts or specialized teams that could resolve this issue quickly?

My business is suffering significant financial losses due to Amazon’s inaction, and I urgently need a solution.

Any help or shared experiences would be greatly appreciated! Thank you in advance for your support!

Warm Regards
