Beginning in Q4 of 2020, Amazon began implementing new requirements for clothing with an eye to improving customer experience and standardized sizing. The requirements are clothing type specific, and Zentail has made updates to make it easy for you to keep your data compliant.

Because the data requirements vary depending on the clothing type, please refer to the section below for the type of clothing you want to sell for information on the attributes you need to include in Zentail to meet Amazon's requirements.

Multiple Clothing Types

Sweaters, Dresses, Coats, Tunics, Socks, Underpants, Sweatshirts, Pajamas, Tunics, Suits, Robes, Tights, Blazers, Track Suits, Salwar Suits, and Vests

Be sure that you have each of these mandatory attributes (Target Gender, Age Range, and Size) and your Smart Type filled out with valid values, and Zentail will be able to infer the rest! Each of these attributes is available in QuickEdit and is importable and exportable, so it's easy to export your SKUs with the correct fields, make the edits to the download spreadsheet and import back into Zentail.

We've set up a QuickEdit view to help you get started! Refer to the Valid Values section below for more information.

Shirts
