Overview

Amazon will roll out a comprehensive update to product listing attributes and enumeration values beginning January 26 2025. The changes aim to eliminate duplicate fields, standardize value options, and tighten compliance across every marketplace. Sellers who do not adjust their listings risk having them flagged, rejected, or removed from search results, which can directly impact visibility and sales.

Key Points

• Effective Date — From January 26 2025, all marketplaces will enforce the new attribute schema.
• Broad Scope — The update covers dozens of categories, including electronics, apparel, home & kitchen, pet supplies, and sporting goods.
• Duplicate Removal — Fields such as “Color” and “Shade” will be merged into a single, more descriptive attribute.
• Enumeration Standardization — Lists for sizes, finishes, and materials will be trimmed and renamed for consistency.
• Compliance Consequences — Listings that still use deprecated attributes may be flagged, rejected, or hidden from search.
• API Impact — Calls to MWS or SP‑API that include obsolete attributes will return errors, requiring payload updates.
• Bulk Upload Requirements — CSV and XML templates must reflect the new attribute names and values before the next upload cycle.
• Global Rollout — The changes apply to every Amazon marketplace, affecting sellers who operate in multiple regions.
• Enhanced Search Precision — Cleaner data will improve filter relevance and recommendation accuracy.
• Seller Support — Amazon will provide a detailed report and help resources to guide sellers through the transition.

How the Update Works

1. Catalog Audit — Amazon’s catalog team reviews each product type to spot redundant or outdated attributes.
   Example: In the “Pet Supplies” category, the attribute “Material” is replaced by “Composition.”
