Fulfillment Center Refuses to Update Wrong Dimensions
Title: Fulfillment Center Refuses to Update Wrong Dimensions — Case ID 17755674151, Need Help
Hi fellow sellers,
We’re a small business and have recently encountered a serious issue with Amazon’s fulfillment center regarding incorrect product measurements that led to an unjustified “Oversize” classification. I’m posting here in hopes of getting some advice or hearing from others who’ve faced similar situations.
The problem:
One of our large-size products was mismeasured by Amazon and is now being classified as an “Oversize – 50 to 70 lb” item. The backend currently shows:
Dimensions: 39 x 19 x 9.5 inches
Shipping weight: 51.00 lb
Product weight: 19.949 lb
Dimensional weight: 50.643 lb
We opened a case (Case ID: 17755674151) and Amazon did remeasure the product. They confirmed that the actual dimensions are smaller, and the product should be categorized under Large, not Oversize. Their measured values are:
39 x 19 x 9 inches
Weight: 19.85 lb
Dimensional weight: 47.97 lb
However, the fulfillment center refuses to update the backend data, claiming that we “changed the packaging.”
But that’s simply not true.
This ASIN has only been shipped once this year. All inventory was from the same production batch, packed identically, and shipped in one FBA shipment (though Amazon split it into multiple fulfillment centers). We never changed the packaging — there was no opportunity to even do so.
We believe the only reason the FC refuses to update the data is because it would result in a retroactive FBA fee refund. This feels deeply unfair and punitive to small sellers trying to play by the rules.
We need help on:
1-Has anyone successfully gotten FC measurements updated when they wrongly cite “packaging changes”?
2-Are there escalation paths beyond Seller Support when the warehouse won't accept verified remeasurements?
3-Any advice on how to push for backend correction based on confirmed data from Amazon itself?
This issue is costing us significantly, and it feels like we’re being penalized for Amazon’s own measuring error. As a small business trying to stay compliant and survive, this experience has been incredibly disheartening.
Any advice, suggestions, or support would mean a lot. Thanks in advance!

Hmmmm..... if I'm reading your post correctly, your item is still oversized.
https://sellercentral.amazon.com/help/hub/reference/G63ZD2BUDXF28WEC?locale=en-US
Any of the following:
Longest side 18 to 70 inches
Median side 14 inches or more
Shortest side 8 inches or more
Unit weight 20 to 50 lb
Looks like you have *all* of the above.

Hey @Seller_2dlF1lhUo1Z08
Like @Seller_z3XfkorVSmnEY said, even with the updated dimensions (39 x 19 x 9 inches) and shipping weight, your product still qualifies as Oversize.
You can check the official Product size tiers help page for details. According to Amazon’s latest size tier table (starting Feb 5, 2024):
- Large Standard size is up to 20 lb and max dimensions 18 x 14 x 8 inches.
- Your product exceeds both the weight and all those dimension limits.
- That means your product falls under the “Extra-large 0 to 50 lb” or possibly “Extra-large 50+ to 70 lb” category.
If you feel the measurements are still wrong, it’s definitely worth pushing Support, but by the numbers here, the product shouldn’t be in Large Standard.
Hope that clears things up! Ezra

Thanks again — really appreciate the discussion and the link you shared!
To clarify, my item is not being classified under the general Oversize category, but more specifically under the “Extra-large 0 to 50 lb” tier — which is significantly more expensive in terms of FBA fees.
However, based on Amazon’s official size tier breakdown (effective February 5, 2024), my item clearly qualifies for the “Large Bulky” tier, which is a sub-tier under Oversize. Here’s why:
Large Bulky Tier Requirements:
Weight: Up to 50 lb
Longest side: Up to 59"
Median side: Up to 33"
Shortest side: Up to 33"
Length + girth: Up to 130"
My Product (confirmed via Case ID 17755674151):
Dimensions: 39 x 19 x 9 inches
Weight: 19.85 lb
Length + girth = 39 + 2×19 + 2×9 = 95" ✔️
So yes, my product is Oversize overall — but within the Oversize tier, it should be classified as “Large Bulky,” not “Extra-large.”
The current classification as “Extra-large 0 to 50 lb” is incorrect and leads to unnecessary FBA fee increases.
I hope this clears up any confusion, and if anyone has tips on how to get the FC to apply the correct sub-tier classification, I’d be super grateful!
