If you create a listing that competes with someone else’s high volume product you will get fake reviews claiming the product is expired. Multiple times this has happened on a brand new listing with no sales, before the product even arrives at Amazon. Expired is one of the go-to false complaints.

In my experience Amazon reliably push expired product back to the seller, at least using the dates that were declared by the seller. This does not stop a seller from claiming what they like, I suppose.
