If you have signed into Seller Central and have the option for Scoutify to check restrictions automatically turned On in your Settings, you will see a red Restrictions button appear on the Details screen with an item if you are restricted.
For information on these settings, please see Scoutify 2: Settings - Restrictions
Please keep in mind that it does take just a moment after you enter the Details screen for this button to appear while Scoutify is collecting the information with Amazon.
Tapping the Restrictions button will show you what conditions you are allowed to sell the product in as well as what conditions you are restricted from selling it in.
This information will allow you to avoid listing and shipping items that will inevitably end up stranded inside of your seller account.
Note: will see the Restrictions button for a product if you looked the product up again on the Search History screen.
