Hi,
I just received this email from WFS, Walmart Fulfillment Services, for an item that has been selling through WFS for over a year. I opened a case on Walmart Seller Center asking for an actual reason that this item was suddenly can no longer be fulfilled by Walmart. So far, they wouldn’t be able to tell me. 
So, I’m posting here hoping that maybe someone here have been through this before. Please advise. Thank you.
Hard to say without knowing what the item is.
Can you tell us the category, at least?
WalMart will not deliver your meth. 
If battery, hazmat, of mains powered, UL/shock hazard. Maybe not NSF cause it’s for drinking water?
IDK, those are the three that come into my head, but that should prevent sale, not just WFS. That’s strange.
Thank you for your reply. They didn’t block me from selling. The listing is still active. According to their email, they told me to fulfill on my own (seller fulfill). I can’t do seller fulfill. Therefore I retired the item for now to prevent the new orders until I could figure out the problem.
If it was hazmat, should I create a new listing from scratch? The current listing that has problem isn’t mine. Someone created it and I tagged along because it was the same product and already has good reviews. Please advise.
I dont know how walmarts catalog works so I cant advise on making a new duplicate listing. Sorry
Walmart Duplicate Listing Policy
I mean if you want to buy a new UPC nobody can stop you.
If a Marketplace item is offered by multiple sellers and it shares the same product identifier (or product ID), the items will be combined into a single listing to help create a better navigation experience for customers. If you submit an incorrect product ID for an item that is already sold on Walmart.com, it may result in duplicate listings.
