Before this change, material_composition was a mandatory attribute, and fabric_type (Fabric Type) was an optional attribute. Both were free text attributes (without enumerations).
There are two changes:
The changes apply to the following listing experiences: 1X1/Add a product, Custom/Category Template, XSD/XML feeds.
In 1X1/Add a product, the attribute “fabric_type” may appear as “Fabric Type”.
Customers use composition of material to browse, search and evaluate products. The availability and consistent representation of composition of material in the catalog enables relevant matches to appear in search results, presence of the product in refinements, and availability of relevant information for product evaluation on the product detail page.
Previously, there were no guardrails in listing experience to help sellers submit composition of material in valid and uniform formats. These changes will help the sellers submit the values in a valid format to enhance product discovery and evaluation.

The migration to fabric_type will happen after November 4, 2021 and the label format validation will happen on December 13, 2021.
The validation of the fabric_type attribute applies only to new listings and there is no validation check on this attribute for existing ASINs. To create new listings for apparel products after the enforcement date, we recommend that you submit values in the fabric_type attribute as per the valid format.
The impacted product types (if available for your country) are: 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, saree.
If you try to upload an invalid fabric_type format, you will receive an error message. Make sure to follow the above guidelines to create a compliant fabric_type.
The change in the listing experience is applicable to the US, EU and UK, India, and Japan stores.
