We understand that not every seller requires an expiration date for the bulk of their items. For this, we have an option inside of your List process that allows you to toggle on/off the option to enter an expiration date.
The Expiration Date field defaults to Off on your Item Listing Details page.
To change the Expiration Date field On, click the eye icon next to it.
Once clicked, the field will no longer be grayed out and you will input your expiration date.
This option is set specifically on the computer you are using. It will stay turned on on your account unless: You toggle the option Off, clear your browser cache, or use another computer.
Note: If Box Content is set to Off for the batch, the expiration date will not carry over into your shipment in Seller Central and will need to be inputted again within the shipment.
Entering expiration dates with Box Content tuned Off will still allow you to create a Reminder for when the product will expire.
