How should I provide Amazon with transparency identifier?

I was auto approved to list this product. Tonight I get an email from Amazon saying that this has to be a transparency enabled product?

Are you selling under other sellers listing or its your own listing?

It looks like you are selling under other brand’s listing and they are using transparency code on their product.

So to sell these items you need to purchase directly from brand with transparency codes.

If you don’t have transparency barcodes, you will need to remove any FBA inventory, as Amazon will block it after a while of you not uploading them.
