Hello from Amazon Selling Partner Support,​

We have reviewed your email and understand that your issue is regarding inactive listing of the ASINs. We will check and help you with this.

1. We have placed new restrictions on existing products that either require you to qualify or we may not be accepting applications currently. If your account becomes eligible to sell this product, you will see “Apply to sell” next to the product in the “Add a Product” feature in Seller Central.

2. You have received a performance notification related to your product and are required to provide additional information before you can sell it again. You can view these notifications through your performance notifications or your Account Health page.
