Amazon introduces three mandatory ASIN attributes – September 30, 2021

Posted by Jimi Patel | September 30, 2021

Effective October 26, 2021, Amazon has introduced the following three mandatory attributes for listings created one at a time or in bulk.

• Net Content: A new attribute set for eight Product Types
• Item Form: A previously optional attribute that will become mandatory for 86 Product Types
• Number of Items: A previously optional attribute that will become mandatory for 154 Product Types

With these changes, all ASINs for select Product Types must have these attributes populated when you submit new ASINs or update existing ASINs. If sellers fail to populate these mandatory attributes, they won’t be able to create any new selection creation in the relevant Product Types after October 26, 2021.
