I’m selling a doormat, the product is 18" x 30" x 0.5". The mat will be rolled up and shipped in a box that is 18" x 6" x 6". Product weight is 4.5 pounds.
I’m planning to send to FBA but my fear is that the product will be classified as small oversize instead of large standard size and I will incur and additional fee per the FBA fulfillment fees for size tiers.
I am doing my first FBA shipment, the item is showing as Standard Size currently. I assume Amazon will measure on their end when they receive it. Is their a chance that they will change it to Oversize?
