Hello @Seller_XtkMA7mhSqRRP,

This is Sakura from Amazon. Welcome to the Seller Forums.

The process depends on the type of product you have, but I recommend reviewing this Guide that will walk you through different scenarios and required steps to list your product on Amazon.

Below is the link to the Seller University Guide:

How to List on Amazon - Guide (PDF)

Let us know if you have any further questions and if you managed to create a new ASIN!

Regards,

Sakura
