Material_composition was a mandatory attribute, and fabric_type was an optional attribute.
We’ll simplify the listing experience by using only one attribute (fabric_type) as the attribute for composition of material. With this change, sellers are requested to use fabric_type when they submit the attribute for composition of material.
To make listing even easier, we are introducing validation on fabric_type and making the attribute mandatory so that users are notified and prevented from creating a new listing with a non-valid composition of material attribute. This validation will be effective from the enforcement date. The fabric_type attribute remains a free-text input. With this change we request that sellers submit composition of material attributes in the valid format.
The changes apply to the following listing experiences: 1X1/Add a product, Custom/Category Template, XSD/XML feeds.
Customers use the composition of material attribute to discover and evaluate products. This change simplifies the information for a better customer experience.

The validation applies to new contributions only. After the enforcement date, you must submit a valid value in fabric_type to list new contributions.
Sellers should review the values in fabric_type for existing ASINs to ensure that the information is correct. Amazon will copy values between material_composition and fabric_type. You will notice this change in your existing inventory. This change doesn’t impact variation themes.
The changes will take place for the following product types (if available for your country): shirt, dress, pants, coat, sweater, underpants, swimwear, kurta, pajamas, robe, socks, hat, bra, salwar_suit_set, shorts, suit, skirt, blazer, sweatshirt, tunic, track_suit, undergarment_slip, camisole, corset, vest, tights, overalls, underwear, outerwear, sockshosiery, kimono, jinbei, yukata, chanchanko, sleepwear, and saree.
