Overview

Amazon will roll out a new set of listing attribute rules on October 26, 2025. The change affects sellers who submit product data through the SP‑API Listings Items endpoint and the JSON LISTINGS FEED. Because the update lands during the holiday shopping surge, any non‑compliant listings risk being blocked at a time when sales potential is highest.

Key Points

• Mandatory fields added — Attributes that were optional last month must now be present, or the listing will be rejected.
• Enumeration refresh — Dropdown selections for several attributes have been expanded, and older choices have been retired.
• Product‑type schema tweaks — The JSON definition for each category has been tightened, altering required nesting and data types.
• Granular categorisation — Broad groups such as “Electronics > Accessories” are split into finer sub‑categories, improving relevance in search results.
• Global enforcement — The new rules apply to every Amazon marketplace, from North America to APAC and the Middle East.

How the Update Works

1. Schema download — Pull the latest product‑type definitions via the Product Type Definitions API. For example, a seller of Bluetooth headphones would retrieve the updated JSON schema that now lists “Bluetooth Version” as required.
2. Feed adjustment — Modify JSON LISTINGS FEED files to include any newly required attributes and replace deprecated enumeration values. A seller previously using “Color: Grey” would switch to the new “Color: Charcoal” option if “Grey” has been removed.
3. Validation run – Submit the revised feed to Amazon’s sandbox environment. If a listing for a kitchen appliance still omits the new “Energy‑Star Rating” field, the sandbox will return a validation error code 400‑X.
4. Production push – Once the sandbox passes, upload the corrected feed to the live Listings Items API. Successful submissions will receive a 200‑OK response, confirming the listing is now compliant.
5. – Review processing reports after October 26 for any new error messages, such as “Missing required attribute: Battery Life.” Promptly correct any failures to avoid downtime.
