Advice on removing & replacing ASIN?

Hi Sellers,

Has anybody with FBA had experience with removing a product ASIN & then relisting the product under a new ASIN? If so were there any complications managing the stock with Amazon warehouses etc?

In short we had our product restricted from product advertisements due to HFSS restriction. It’s been incorrectly applied to the product as we’re exempt but after 8 months of trying to get through to Seller Support we’ve given up.

We’re going to attempt to remove the product & relist it so the restriction will no longer apply but knowing how frustrating Amazon can be, wanted to know if anybody had similar experiences & met with any challenges?

Thanks in advance!
