For months l've been trying to create my first Amazon shipping label for my item after FINALLY getting my item approved but l keep receiving errors

Problem 1: I need to change my condition from New to NewOem but it’s locked and greyed out which is why they think it’s causing the issue. Amazon wants me to start over with the listing and select proper condition but that means I have to pay for GS1 again for a new bar code. I also don’t want to do this because it took months to approve this one listing. I cant start over.

Problem 2: I’m having trouble getting Amazon to approve my product in other 2 color options. They only approved 1 color.

For Problem 1, you most likely do NOT need to buy another GS1 barcode. In many cases, Amazon support can update the condition type internally or you can create a variation/relist using the same GTIN if the product itself is identical. “New OEM” is treated differently from standard “New,” and if the condition was selected incorrectly at listing creation, the locked field usually requires Catalog Team intervention instead of normal Seller Support.
