Overview

On September 29 2024, Amazon rolled out a comprehensive revision of listing attributes and enumeration values across all marketplaces. The update removes redundant fields, tightens allowed values, and enforces uniform attribute usage worldwide. Sellers must audit and adjust feeds before the change takes effect to prevent listing rejections and maintain product visibility.

Key Points

• Attribute pruning — Amazon will delete duplicate fields such as “Fabric Type” that appear in both apparel and bedding categories, simplifying data requirements.
• Enumeration refinement — Valid values for attributes like “Color” and “Size” are narrowed; for example, “Red” remains the sole acceptable entry for many apparel listings, replacing vague terms like “Reddish”.
• Cross‑marketplace consistency — The new schema applies identically to North America, Europe, and Asia‑Pacific, ensuring a product listed in the US and the UK uses the same attribute set.
• Mandatory updates — Listings that still use removed attributes or invalid values will be flagged and may be rejected until corrected.
• API and Seller Central updates — Product Advertising API endpoints and bulk upload templates will reflect the revised attribute structures from the effective date.
• Impact on feed templates — Existing bulk upload files must be revised to drop obsolete fields and incorporate new required ones, such as replacing “Fabric Type” with “Material” for apparel.
• Validation tools — Amazon’s “Validate Attributes” API and Seller Central validation feature will now enforce the updated lists, providing real‑time feedback on compliance.
• Rejection rates — Early reports indicate a 15‑20 % drop in attribute‑related rejections after the change, highlighting the importance of timely updates.
• Seller Central guidance — Amazon released a detailed attribute guide and sample feed templates to aid sellers in mapping their data to the new schema.
• Monitoring metrics — Post‑update, sellers should track listing health and traffic metrics to detect any inadvertent attribute misconfigurations.
